The farmers in the northern part of the lower peninsula of Michigan or the area commonly referred to as the "cut-over" area of Michigan (Figure l) were particularly distressed. For various reasons agriculture in this area has never_ attained the degree of stability found in southern Michigan. Many of the farmers are forced to rely upon factory jobs in adjacent industrial cities for supplemental income and others eke out a bare subsistence from poorly equipped and ill managed marginal or sub-marginal land. The cut-over area of Michigan has approximately 40,000 families. The history of this area indicates that most of them intend to stay even though it might be to their advan- tage to relocate. Regardless of the purely social aspects, of agricultural deve10pment in the cut-over area, there are immediate and more practical aspects. One of the most pressing problems confronting the farmers in this area is that of adequate housing, including dwellings as well as livestock and storage structures. Al- though farm buildings throughout Michigan are in a critical state of depreciation and obsolescence, the buildings in the cut-over area are even more seriously depleted. Numerous requests for assistance in obtaining more “I r ’. _ .. -.——.-—_..——— DICKINSON / . Figure No. 154) Cut-over Area of Lower Michigan Cut-over area of lower Michigan.

Some interest is shown in using readily available native woods such as jack-pine, aspen, balsam, poplar, etc., but the majority of lumbermen, local builders, and even farmers, are pre- Judiced against using such "inferior" woods. It may be of interest to note that at a meeting called by the County agricultural agent in one of the cut-over counties to dis- cuss this problem the suggestion that these so-called infer- ior woods be used in farm construction was received with _ evident disfavor. One farmer even stated that he would go without buildings before he would be guilty of using such_ worthless lumber. The appearance of the buildings in this county would seem to indicate that other farmers felt the same way. In 1935 the Farm Security Administration was set up to help deserving farmers rehabilitate themselves.’ One of the first requests from this agency was for plans of farm build- ings that could be constructed entirely from farm woodlot' timber without the necessity of buying any article, except possibly nails and other hardware. Since most of these farmers did not have available cash for the purchase of standard lumber from their local dealer, the utilization of local lumber seemed like a practical approach to the problem of obtaining more adequate buildings for the far- mers in the cut-over area of Michigan. In this cut-over area there are approximately 7,000,000 acres of timber land with a potential supply of lumber that provide adequate housing for the farm families and all their livestock, crops, and equipment. Much of this timber is on individual farms and could be converted into usable lumber at a cost of only a few dollars per thousand board feet for sawing, plus some farm labor for cutting and hauling the logs to a local mill. Additional timber is available on thousands of acres of state and national forest land and can be purchased from the preper authorities for a very low_stumpage fee (Figure 2). At the time this project was started, this fee for some species of timber was as low as one dollar per thousand board feet. There is evidence that the supply of aspen and jack- pine is increasing so fast that the problemof clearing its from state lands is becoming a serious problem. The Michigan State Department of Conservation would welcome an Opportunity to c00perate with farmers in making this timber available for farm construction.(5gl One wonders why more of this timber has not been used. This project was undertaken in an attempt to answer this question byrv l. Ascertaining the need for farm building construc- tion in the cut-over area of Michigan. 2.

DeveIOping plans adapted to native lumber or adapting it to present plans. It was the original intention to make these studies in a representative county in each of the "Type of Farming" areas in this region as classified by the Farm Management Department of Michigan State College (Figure 3). Owing to tire and gasoline restrictions, most of the field studies were made in Midland, Clare, Gladwin, and Alcona Counties. Since these counties are typical of the larger part of northern Michigan where farm improvements are needed and_ where the type of building material available is similar, if not identical, the findings reported here may be applied to the entire northern half of the Lower Peninsula and the whole of the Upper Peninsula of Michigan. REVIEW OF LITERATURE Numerous general statements have been made concerning the desirability of using native lumber for farm building construction but definite recommendations have usually been omitted regarding specific uses of the species of lumber most readily available to Michigan farmers at the present time. The practicability of using native lumber for farm construction is indicated by the following statement from a federal publication: "The importance of the home forest as a reserve for 'pinch' times cannot be overestimated. In the midst of the lumber shortage and high prices during the fall of 1919 and the spring of 1920, for example, communities and individual farmers having local supplies of standing timber are reported to have suffered the least from the widespread deterioration of farm buildings and deferment of necessary new construction. The effect has been not only smaller losses of cr0ps and livestock but better farm conditions and more contented farm labor. "Lack of knowledge of the proper use of timber is one form of farm mismanagement. It is a mistake to saw up choice logs of white oak, ash, cherry, and yellow poplar for rough uses at home or to‘ use clear black walnut for gate boards or split up white oak butts for fence posts. Many valuable logs go into crossties which would bring the owner much more if sold as saw logs."(28) This bulletin was prepared for national distribution but most of the woods mentioned are native to Michigan. When this statement was made, most of the "choice woods" had been disposed of through various wood using industries in the state and were no longer available. However, atten- tion was called rather forcefully to the practicability of using native woods for farm lumber and to the lack of know- ledge if all woods were not used to best advantage. No information was given on what woods could be used for farm lumber, how they should be handled or where they should be used to best advantage. This author also comments on the importance of the farm woodlot as a source of firewood when he says that in 1920 enough firewood was cut from the farm woodlots of this coun- try to reach four times around the world. However, there was no word of caution about using for firewood timber that might better have been used for rough lumber. This would also seem to be a factor contributing toward mismanagement of the farm woodlot. A publication released by Michigan State College includes the following: "The farm woodlot is capable of producing much of the rough construction and repair lumber, fence posts, part or all of the fuel wood needed on the farm, and may also produce periodically an excess of timber suitable for sale." (12) No mention is made of what woods to use for firewood, what ones would be most suitable for farm construction or those which would be most in demand as commercial timber. An experience of a Michigan farmer in using native lumber follows: "Glenn Ingram, a farmer living near Hastings, Michigan, reports very satisfactory returns from 10 acres of woodland. During a period of eighteen years, from 1910 to 1928, Mr. Ingram out 55,000 feet of timber, part of Which was sold and part used on the farm for building purposes. The complete record of returns, uses made of tim- her, and years of cutting follows: 1910 - out 14,000 feet; built a farm home. 1913 - cut 13,000 feet; sold and cash put into improvements. 1918 - cut 7,000 feet; used for shed, henhouse, and flooring. " 1927 - cut 17,000 feet; built a barn. 1928 - cut 2,000 feet; used for repairs. "In addition to these returns, the woods have produced an average of 100 gallons of maple sirup a year, besides furnishing fence posts, Whipple- trees, and other products as needed on the farm. "Mr. Ingram has followed a simple cutting plan, taking out the larger ripe trees and leaving the younger ones to grow another crOp of timber. ‘ Special care was taken in cutting operations to protect all young promising poles and sapling trees. This system kept the woods in good tim- ber- producing condition. The woods were pastured at first but after studying the problem, the owner decided that his stock damaged the timber, so he has fenced it off. "'This lO-acre woodland is just as valuable as any other field on the farm,’ Mr. Ingram says. A recent offer of $2,500 for the 10 acres was no inducement to Mr. Ingram to sell. ’He has'"”' decided that his woodland holds a very necessary place in his farm-management program."(45) A more recent reference to the use of home grown timber for farm construction in a state where conditions are almost identical to those in Michigan still calls attention to the use of hardwoods that are scarce and rapidly becoming more so. Little effort has been made to encourage the use of Jack-pine and aspen although in most of the cut-over areas of Michigan,where economical farm buildings are primarily needed, these woods represent the most readily available source of lumber. In much of the earlier cut-over region, trees of the above species are from thirty to fifty years old and are ready to be harvested. Yet farmers in this area are going without adequate buildings because they can't afford to buy the out-of-state lumber usually handled by local dealers, but they still hesitate to use such so- called inferior wood for building purposes. AGRICULTURAL HISTORY OF CUT-OVER AREA OF MICHIGAN The amount of lumber used on any farm or in any farming community will vary with social and economic conditions pre- vailing in that area, and upon the decree of development or stability of its agriculture. The lumber required will be used for the following purposes: 1. Repair and maintenance of present buildings. 2. Replacement of existing obsolete and wholly inadequate buildings. 5. Construction of new buildings for: a. Expansion on present farm units. b. Anticipated increases in farm units. Although there seems to be some tendency in the more highly develOped agricultural communities to replace lumber with more permanent building materials, it is estimated that at the present time more than ninety per cent of all farm buildings in the United States are constructed of lumber.(17) The cut-over area of Michigan would certainly be no exception unless the percentage of wood buildings be even greater than in typical agricultural regions. In most farming communities, agricultural deve10pment has reached its peak. Therefore, future lumber consumption in these communities can be quite accurately estimated because lumber will be needed primarily for'maintaining the present farm buildings by repair and replacement. Social and economic conditions in the cut-over area of Michigan are somewhat uncertain and perhaps a brief history, of the agricultural developments of this area will be helpful in analyzing the lumber consumption based upon farm building requirements for this area. The development in the northern part of the lower penin- sula of Michigan has lagged far behind the deve10pment of agriculture in the southern part. Variation in soil and climate are not;the only reasons for this difference. In southern Michigan the timber was cut primarily to prepare the land for farming and most of the lumber was used either on the farms or was sold to local wood using industries and the money so obtained used to further develop the farms. In the northern part of lower Michigan, the pine forest was cut primarily for the lumber and not to clear farm land as it was needed. As long as the timber remained, local communities prospered but from the very beginning it was the gold rush type of prosperity. The environment of the lumber camps provided little inducement to farmers who were seeking the security of a more permanent agricultural commu- nity. Most of the camp followers came north in the winter to earn cash wages which they either spent at the end of the season or took south to live on while developing farms in southern Michigan, Ohio, or Indiana. A few clearings close to lumber camps and villages were converted into farms which helped to supply the demand for large quantities of food and forage. A more permanent type of agriculture was discouraged by the large lumber companies “who feared that brush fires incidental to land clearing would endanger their mills and timber holdings and also because they wished to avoid the higher taxes required for schools, roads, and other improvements in permanent agricultural communitiesJEG) In such an atmosphere of insecurity it is not surprising that few permanent farm buildings were constructed. In fact, very few were needed. In most cases even the part-time far- mers lived in the lumber camps. The crops were consumed almost as soon as they were harvested. The few head of live- stock roamed the range in the summer and in the winter were stabled with the camp horses. -10.. In the short span of about twenty years the land had been cleared with a thoroughness that left little doubt as to the future of lumbering or of agriculture in this cut- over area. With the disappearance of the lumber industry, the only enterprise that could have sustained agriculture until it became self-sufficient, went the hepes of agri- culture. As the lumber mills moved westward, land in northern Michigan was left to become tax delinquent and many of the inhabitants were left in a wilderness of brush and stumps without funds, without employment, and without markets for their products (Figure 4). Even though they might have had capital to sustain themselves during the five to ten year period required for the development of selffsufficient farms, they could not survive without mar- kets. One author gives the following summary of this critical period: "In the northern part of the state, agriculture was more or less incidental until after lumbering had passed its zenith. All of the timber that could be disposed of was cut, and most of the ' rest was destroyed in logging or by fires. The land did not remain timbered until it was wanted for farming, as in the southern counties, but was practically stripped of merchantable material before it was made available to settlers. When the settlers came, they feund little standing timber to supply their needs for building material, posts, or even fuel, except for scattered patches in the swamps. Without enough capital to buy such material, they were compelled to get along with crude, makeshift buildings, and poor fences or none. The pine stumps and roots supplied fire- wood for many years, and in some localities are still the principal saurce of fuel and fencing, but where the stumps have been consumed many farmers have no wood except small birch and aspen, hardly large enough for bean poles. In many in- stances, even the farmers who have timber cannot sell it because the sawmills and wood using indus- tries have gone, taking their railroads with them." (41) Figure No. 4B Figure No. 40 -11- "A wilderness of brush and stumps." This was the settlers' heritage. Ground cover suitable for grazing, the first step in converting this land to agriculture. Grazing was followed by cultivation between stumps, but time- consuming and costly land clearing opera- tions were necessary for even subsistent farming. -12- Although conditions may have seemed almost h0peless to some individuals, the Opportunities in the cut-over area were grossly exaggerated by others who stood to profit by rapid settlement. The large lumber companies wished to dispose of their holdings to avoid the burdensome tax and the railroads to bolster their diminishing traffic. Either directly or through colonization agencies, they organized intensive advertising campaigns to dispose of their holdings. A development bureau is quoted as follows: "Thousands of settlers have come during the past few years, other thousands have bought land for investment or for future settlement. Everywhere there are new farms, new clearings, new buildings, good roads, schools, and churches. The country ' has passed from a lumbering to a farming community."(40) The success of these land selling schemes is indicated by the growth of farms shown in Table No. 1. TABLE NO.

The demand for farm products at relatively high prices during and after World War I gave added impetus to the colonization movement although the number of.farms continued to decline after 1910. Many of the partially developed and abandoned farms of pre-war settlers were resold to these new farmers. The type of agriculture prevalent.in the cut-over area during this period is indicated in Tables No. II and No. III. TABLE N0.

The total capital of the average farm studied is $6,856 and the average family income only $559. This is little enough on which to live; even when none of it has to be used to pay interest." (51) In spite of low farm income, these farmers invested heavily in land clearing Operations and in other improvements such as buildings out of all proportion to the productive_ capacity of the land. The increase in building investment is shown in Table No. IV. Some idea as to the source of capital that was used to make these investments in shown in Figure 5. As prices began to decline at the end of the war, the fate of many farmers, particularly those who had settled on the poorer type of soil, is shown by the large number of .NOI N \ HV'HOO jO cn C‘ v '90. m ‘9 ammq maacemog Exam zqumon “H1 m .02 osswam _qm_myrflzm_ mzsozqamago mzaon moqoamo§.§mqu m; mmm_ 0mm. m«w_ on_ new” alml -- -4- - - u - i vallli---------J..-iil|--.i-fil - - - - _ ----, -. --.:1;-a-'-- r;,.,,‘. a -- - -1 .1 - n - - + i m. + + m_ M? - + I Q I - , n , _ \ I 4-...m.-m_§w,.3m_-zsT - Tl! . ,. l .J 8 l 1 . “a .t i. 1T1?

(Figure 6). Other farmers, perhaps because they had no place to go, were forced to remain and seek part time employment in the nearby shOps to maintain a standard of living that was a mere subsistence. (Figure 7.) Fortunately for these farmers as well as for those on better developed farms, part time employment and greatly expanded markets were created by the tremendous growth of the automobile and allied industries in Michigan and by the increased volume of tourist trade. Had it not been for these sources of additional income, the number of foreclosures and abandoned farms would undoubtedly have been larger during the prolonged period of depressed farm prices of the 1920's. Regardless of accumulating evidence that much of the cut-over area was not suited to permanent agriculture and that the apparent prOSperity of the region was built upon borrowed capital and nourished by markets of a highly variable nature, those interested in the region continued to exploit its resources. "It would be easy to cite by title and page the overt encouragement given by state and federal agencies to the land deve10pment schemes of private Operators. They too were blinded by the emotional appeal of the movement to the practical and long time problems incident to a Judicious use of natural resources."(20) In the May, 1959, report of the National Resources Committee may be found the following statement: "This booming of wild land for farms is not ancient history. It was only two decades ago that govern- ment agencies in each of'the three Lake States, in common with other states, put out booster lit- erature encouraging the selling of cut-over lands for farms and promising the settler that he could grow rich in these regions."

Yet census reports showed a decided drop in the rate of increase in farms in the cut~over area of the three Lake States by 1920, and in Michigan, which had been cut over earlier, the rate of increase in some counties reached its peak about 1910. Even during the first World War some people began to realize that abnormal war production had clouded the real issue of prOper land utilization and management. In the early 1920's, this was said: "Most of the land not now in farms is worth more for forests or grazing."(55) In 1923. Dr. L. C. Gray, in discussing the problems of land economics and land utilization, indicated that there was little need for the development of new lands, particularly wild lands of doubtful value, and that continued unlimited production as urged upon farmers as a war measure would lead to trouble- some agricultural reverses. (55) In spite of these warnings farming conditions in the cut-over area of Michigan remained about the same until the agricultural depression which began in 1921 and continued through the 1920's, with only minor indications of recovery, finally culminated in the total depression of 1929. Omitting reactions to the second World War, farming in the cut-over region since 1929 needs little elaboration. It was a period of curtailed income, high taxes, increased debts, moratoriums on foreclosures, jobless thousands re- turning to farms and finally direct government relief for approximately 8,000 rural families in Michigan. This review of the history of the cut-over area has -18- been given to acquaint the reader with the social, economic, and agricultural background of conditions that prevailed when this study was undertaken. ECONOMIC IMPORTANCE OF ADEQUATE FARM BUILDINGS It hardly seems necessary to justify the need for adequate farm buildings. The fact that the farm building investment in Michigan is approximately 500,000,000 dollars would seem to indicate the importance of farm buildings to any agricultural enterprise. The investment in buildings is almost as large as the investment in land and nearly four times as large as the investment in machinery. (9) The investment in buildings by counties of the lower peninsula of Michigan is shown in Figure 8. The relationship between buildings and farm income is shown in Table No. V. A study of this table reveals that on farms of eighty acres or less with an average of sixty-six tillable acres there were 5 2/5 tillable acres per animal unit for the third highest labor income group and 4 1/2 tillable acres per animal unit for the third lowest labor income group. This shows a greater concentration of livestock on the farms having higher labor incomes. The value of crOps per till- able acre for the third highest labor income group was $15.44 and for the lowest labor income group was $12.55. This may reflect the value of fertilizer in the form of farm manure returned to the land which would not be avail- able without livestock. On these same farms the livestock income per tillable acre was $28.12 for the third highest MACK/NM Figure No. 8 (8) Building Valuation by Counties. Less than 1,000,000 1 to 2,000,000 2 to 3,000,000 3 to 4,000,000 4 to 5,000,000 - 5 to 10,000,000 More than 10,000,000 ° -19- labor income group and $16.15 for the third lowest labor income group. The number of livestock seems to be a most important factor and livestock require buildings. The building investment per tillable acre was $44.89 for the highest labor income group and $58.80 for the lowest labor income group. Although buildings seem to be necessary for a suc- cessful farm program, it may be possible to have a larger building investment than the most practical farm program _ can Justify. It is interesting to note that in two of the farm classifications, according to size, the building in- vestment per tillable acre was higher for the third highest labor income group but the building investment per animal unit was lower for the third highest labor group in every case. Perhaps the buildings for the lower income group were not utilized to capacity. Certainly an increase in the number of animal units would have lowered the building investment per unit, but there is also the possibility that the building investment was abnormally high. There is a growing realization on the part of farm building specialists that the investment in farm buildings may be dispr0portiona11y high. A proper concept of low cost farm'buildings does not presume a lowering of stan- dards or a reversion to outmoded methods. On the contrary the problem of designing low cost farm buildings constitutes a challenge in the adaptation of plans and utilization of available materials that will reflect greater utility value rather than the wealth put into their construction. -20- As an example, the Doane Agricultural Service of St. Louis, Missouri, in establishing allowable building costs for their clients have ad0pted a capital investment of $22 per unit of livestock for a beef animal including all buildings and accessory equipment such as yard fences, feed bunks, and water tanks.(14) Actual experiences show that costs of $60 to $70 per unit of livestock are not unusual for buildings of this type exclusive of the above mentioned equipment. As a means of lowering building costs, the Doane Service suggests a careful study of building plans with the idea of adapting them to the use of native materials. In discussing the problem of how to obtain adequate farm buildings with limited income, Deane G. Carter suggests that there are almost inexhaustible supplies of native materials such as stone, logs, poles and low grade lumber that can be used in the construction of satisfactory farm buildings. (11) This would seem to be particularly applicable in farming areas of low income such as the cut-over area of Michigan. A project on the utilization of jack-pine and aspen for farm buildings in areas where it is readily available is therefore in line with current opinion on the use of building materials for farm construction. LUMBER REQUIREMENTS FOR REPAIR AND REPLACEMENT OF PRESENT BUILDINGS Lumber for farm construction will be required to repair and maintain existing buildings, to replace obsolete or in- adequate buildings and to build new ones.

Table No. IV also shows the number of farms and the value of farm buildings for the state and for four typical cut-over counties from 1900 to 1940. It is interesting to compare the per cent change in number of farms with the per cent change in the value of farm buildings. From 1900 to 1910 the number of farms increased only 1.55% while the value of buildings increased 80%. From 1910 to 1920 the number of farms decreased 5% although the value of buildings increased 75%. This increase in building valuation resulted in part from additions andimprovements on individual-farms during this period of agricultural prosperity as previously mentioned. It was also influenced by the general upward trend of basic price indices. The graph in Figure 9 shows the rela- tionship between prices paid to farmers and the price of building materials during the period from 1910 to 1915. This price differential was favorable for the construction of new farm buildings. By following these curves through the years from 1929 to 1940, it is not difficult to understand why the building valuation on many farms declined and why improvements and repairs were neglected. . From 1920 to 1950 the number of farms decreased 15.7% but the value of buildings increased 28%. Agricultural -22.. prosperity for this region had apparently reached its peak. The period from 1950 to 1940 needs no explanation, and the -increase in number of farms while the building value de- creased tells the story of the back to the land movement and depressed farm incomes. It is apparent that most of these farm buildings were constructed prior to 1920. There- fore the majority of them are from 20 to 50 years old and many of them much older. If the average life of a farm building may be assumed to be 40 years, it is obvious that those buildings constructed from 1910 are 100% depreciated. Many of those that have been maintained and are still usuable are obsolete and wholly inadequate for present production methods. But if these buildings are to be maintained, an annual eXpenditure of $15,041,952 will be required to provide for an annual depreciation of 2%% on a building valuation of - $521,677,519. No sum approaching this figure has been spent. What actually happened is shown in Tables No. VI and No. VII. Beginning in 1951 and continuing through 1955, the money spent for buildings on scme of the better farms of Michigan failed to cover the cost of depreciation. This accumulated depreciation over the past ten to twenty-year period must be faced eventually either by making needed repairs or by replacement. Enormous expenditures will be required during the next few years to make up for past neglect and to care for current depreciation, repair and replacement. In addition to these data showing the need for lumber, it has been estimated that approximately 850 board feet of lumber will be required annually on each farm in Michigan to meet the requirements for repair and replacement of existing buildings and an additional 150 board feet per farm per year to provide for new construction based on the 1920 to 1950 distribution of new farms.(18) These estimates are average for all farms in the state and probably are too low to meet the requirements in the cut-over area where many of the original pioneer buildings are still being used and where repairs and improvements to more modern buildings have consistently been neglected. Additional data showing the need for repairs are ref ported in the Sixteenth Census of United States for 1940. Table No. VIII was taken from this census. Various other surveys in recent years have provided conclusive evidence of the need for farm building improve- ment by giving statistics on specific structural require- ments for lumber, by showing financial loss owing to unchecked depreciation and by showing a photographic record of existing buildings. Because of the difficulty of further adequate descrip- tion on this subject, a photographic record of typical farm buildings in the cut-over area is given on the following pages. med mfl.mm em I we H.m mm.HH d.m mm.HH mma emmm flea- eaeenH toned amoeba m\H Hes oo.mm ooa mm m.ma emeH m.m mmima HmH mame cam . me - eanem Ham mmam Hm.mmm sea Haam mdma mo.omm H.e ma.mam Hom mommm mmeam eaoeeH gonna pneumam m\a Hma - mmmom mammamHa mmmmm>mu mmmum mammquHa mm>o qzm flea , mma me.em mm Hm m.m Hm.ma m.m mH.mH moa mmma mad maeeeH aepmq neeeoq m\H meH mm.mm mHH om m.m emeH m.e em.ma moa mmmm mam me - easem Ham meam moummm mad Hoam odm sodomm mde HmeHm wad Hmemm ommam eaoenH gonna enenmam m\a moa3v mmmom mummmaHe.mmmmm>m . mwmom mmmmqua oea on em mea om.mm me me ¢.e mH.mH m.e mm.mH em «and .mmH- eeeenH genes amoeba m\H omH amine ooa Hm m.m meiam m.m om.ma mm mama Hem - me - manna Ham Hmam mm.eem mod beam e.m ma.mmm edm eeimam mm Hommm mme m eaeeeH moped neenmam m\H mm --mmmom mammque mwmmm>«.u mmmmm mammqua om zmme mmmq ‘ Wmlma dmmu HN SO 0N VOW. rm LOA VTu .dnu In... 3...... mmu mm mm mm emu mu nme mu 3 we 88p vsp «be Dan-Ad 8m 99% We swan—v 9T... 8 00 new nus m.u I4? 03?

A better appreciation among farmers in general as to the actual value of adequate but inexpen- sive farm buildings. 2. The development of a government subsidized post-war rural housing project. 5. The degree of improvement in rural living standards. In addition to the need for repairing and remodeling old buildings, there is a need for additional new buildings to accomodate the increased livestock and feed, if the present small farms in the cut-over areas are supplemented from out- side labor in nearby factories. In the event that factory employment wanes and the} farmers are obliged to depend more and more upon farming, . they will have to increase very materially the average area under cultivation, if they are to continue in the business. This can be done by clearing more land where feasible or by consolidating existing units and reducing the number of farms. If the present number of units remains, it will be necessary to add 500,000 acres of improved land in the upper peninsula and 950,000 acres in northern lower Michigan just to bring them up to the 70 to 90 acre farms of the better developed southern counties. .This is more land than has been cleared in the whole state during the last quarter century, and for the upper peninsula it would mean more than doubling the present improved area. But as it is, settlers have already cleared the better lands in the cut-over districts and many of them have cleared about all the contiguous land that the topo- graphy and soils will permit. In many places the surface is so broken or the good soils are so spotted in distribution that it is physically impossible for a settler to increase his area of cultivable land except by acquiring that of some other settler. An increase in improved acreage is by no means all that is needed to insure the future of farming in the north. Much labor and money must also be eXpended to provide more adequate farm buildings and other equipment, and to build more attrac- tive farm homes, or the more desirable elements of the next generation will gradually pull up stakes and leave the region. Many of the farms in northern Michigan are still in the frontier stage with lands only partially cleared, fences lacking or temporary makeshifts, barns usually crude and inadequate and rarely painted, and dwellings largely taZpa- _ per shacks of one or two rooms or even log cabins, chin ed with clay. Such conditions are perhaps to be expected in a frontier settlement, but hardly in the homes of a permanent, prosperous agricultural community. National attention was focused on better rural housing as an aid in the solution of unemployment previous to the present war emergency and it is evident that new measures will be used to stimulate farm construction when the time comes. This problem ranks high on the list of post-war pro- jects and some rural housing program is almost a certainty. -34- The effect of this program upon lumber requirements will depend upon the number of houses constructedjwhich in turn will depend upon what the farmers accept as a minimum desirable standard. It is difficult to set a minimum stan- dard for any group or class of people. No definite informa- tion exists as to what farmers in the low income group will adopt as a minimum dwelling for themselves or how many are now living in dwellings below their proclaimed standards. PRESENT SOURCE OF MICHIGAN LUMBER It is estimated that less than half of the nearly 400 billion board feet of Michigan's original stand of tim- ber was actually converted into lumber and very little of this was used for the construction of farm buildings in Michigan. As early as 1920 nearly 60% of the wood used in Michigan was shipped in from outside sources primarily from the southern hard pine region and from the west coast douglas fir region. The transportation charges alone on this lumber amounted to $16,000,000 in 1920 or 50% of the total cost. The dependence upon outside sources for lumber steadily increased and the price of imported lumber also continued to advance. The fol- lowing tables show the source of lumber consumed in Michigan in 1958 and the price by years. -35- TABLE NO. IX (58) TOTAL APPARENT CONSUMPTION OF ALL WOODS IN MICHIGAN IN 1958 IN M FEET B.

Figures are not available to show what part of the lum- ber consumed in Michigan is consumed on the farm nor the per cent of consumption by species but experience would indicate that at least 90% of all lumbe: used on the farms of Michigan, at the time the study was made, was also imported. However. as previously mentioned, the small amount of this lumber used on the farms of the cut-over area was insufficient to provide adequate buildings. If these assumptions are correct and this study indicates that they are, the supply of native timber certainly should be given more consideration as a source of lumber for farm construction. AVAILABILITY OF ASPEN Aspen occupies more area of forest land in Michigan than any other tree species. Together with other poplar species it occupies nearly one-third of the forest cover in the cut- over area (see Figure 15.). 5- \\ e!’ mama/4 ”CRIN“ /, «‘EK- / F'— .54 Figure No. 15 — Acreage of Forest Cover Types in Cut-Over e _ “ Area of Michigan (47) M” "m 7% _ Species Acres mm. mm ‘ Other Pine 75,000 ' / We. - ammw , u ,.1 - M//// / "0'0" 44.

However, an estimated volume of saw timber is given in Figure 14. The relatively small volume of saw timber from such a large area is explained by the fact that the majority of aspen trees are small diameter stockymeasuring less than six inches in diameter.

On this basis it is predicted that within 25 years 15 to 40 per cent of this stand will become merchantable_and in 25 to 50 years 60 to 85 per cent will become merchantable.

If the figures in Table No. XII are assumed to be average for the entire area of aspen forest in the cut-over area and it is further assumed that this forest cover is soil of medium fertility, then the volume of sapen on the 2% million acres of cut-over land is increasing at the approximate rate of 250,000 cords per year only on the stands 25 years of age and over. This volume of wood can be converted into equivalent board feet of lumber per cord by using the conversion factors from Table No. XIV. By using the conversion factor of 265 for aspen bolts of six inch t0p diameter, this 250,000 cords of aspen would be equivalent to 66,250,000 board feet of lum- ber. The fact that this increase in the volume of aspen wood cannot all be converted into lumber should be emphasized. These estimates, however, do indicate the rapid increase in the total volume of aspen wood, and it seems reasonable to assume that the increase in the supply of potential aspen lumber is proportional. In concluding their study of aspen, Johnson, Kittridge, and Schmitz say, "The large area of land occupied by aspen forests in the Lake States makes it essential that the species be utilized more extensively. The wood is growing faster than it is being used and the short life of the tree requires that consumption be more nearly balancedwith growth, otherwise a large portion of the crop will be wasted." (24) PROPERTIES AND UTILIZATION OF ASPEN Available information on the pr0perties and utilization of aspen generally has been limited to the large commercial users of this wood. There has been little incentive to make this information available to small local builders, since aspen has been so little used for building construction. However, those industries, particularly the paper and excel- sior manufacturers, which are the largest users of aspen, have known of its desirable properties for these specific uses. Wood distributors and users in the aspen area have always been prejudiced against the use of aspen. This attitude is due chiefly to the relatively small size of the mature tree and the generally poor appearance of the tree and the finished lumber. ' Other species such as cottonwood, eastern hemlock, jack pine and red gum have passed through a similar stage. A com- parison of the properties of aspen with those of other, better known, woods should remove some of the prejudice against aspen and aid in the more extensive utilization of the species. A comparison of the properties of aspen with those of other woods for which it might be substituted is made in Table No. XV. In discussing the use of aspen for structural lumber, Johnson, Kittridge, and Schmitz, have this to say: "That a8pen can be used for lumber and that such lumber will give good service under certain con- ditions has been amply demonstrated.

Although such construction was undertaken during this study, it is questionable whether the time alloted will be sufficient to draw any definite conclusions upon which design recommendations can be made. However some preliminary data have been obtained which are discussed later. To obtain data which could be applied immediately to recommendations on the utilization of native lumber, particu~ larly aspen, in farm building construction, a survey was made in previously identified areas where such construction is most urgently needed. No definite survey procedure was followed in making this study. The primary objective was to contact individuals who had used native lumber and by inspecting the buildings and studying the building requirements of these individuals determine: 1. The need for native lumber. 2. How native lumber was being used. 5. The durability of native lumber under actual service conditions. 4. The user's reaction to the desirability of using native lumber. 5. What improvements in the manufacture, distribution and utilization of native lumber would increase its use. The users of native lumber visited in this survey were located through contacts with county agents, local saw mill -47- operators, and by inquiries from those interviewed in the course of this survey. The data collected are recorded on the following pages. The first eight reports are on farm buildings and the remainder are reports on miscellaneous types of construction.

Other buildings needed on this farm and which will be constructed are: a new poultry house for 200 hens, a granary for 2500 bushel of grain, a machine shed, and the house, which was not photographed at the request of the owner, will be remodeled. It is estimated that at least 20 M boardfeet of lumber will be required for these proposed buildings. If the supply of Norway pine lasts until these proposed buildings can be constructed, it will be used. Otherwise, the owner says he will use jack pine or aSpen. -49- Figure No. 16 Farm - No. 2 Location - Gladwin County Size of Farm - 120 Acres Woodlot - 60 Acres of Timber Type of Farming - General,Livestock and Dairy Type of Soil - Class 1 Sandy Loam Buildings Needed - Barn Poultry House Granary House Remodeled Lumber Requirements - Estimated 40 M Board Feet Type of Lumber Likely to be Used - Mostly Aspen, Other Hardwoods The young couple who had moved from the city onto this farm left to them by aging parents were considerably depressed over the probable cost for new buildings which they considered essential.

As he says, this cannot be accomplished until the necessary buildings are constructed.

One of the advantages of using aspen logs for this type of construction is its relative freedom from cracking in the process of seasoning. This character- istic is shown in the enlarged section of a corner of’the building. Figure No. 258 Note freedom from cracking in all 10gs except one. This one is a spruce log. -57- Figure No. 24A Figure No. 24B This new poultry house was constructed in 1941 of aspen poles approximately four inches in diameter. It will replace the old poultry house also shown. The actual cash outlay for this building was less than $25, which includes the con- crete foundation, roofing and windows. The poles were cut from the woods in the background. The use of small aspen poles or logs is one practical method of using small dimension trees for much needed build- ings on marginal or part time farms. The poles are slabbed on two sides to form a tight wall without making it necessary to chink the cracks. If aspen poles are used in this manner, placed upon a concrete foundation and preferably treated with some preservative, they should last for many years. A small stack of well-piled aspen lumber has also been accumulated for needed repairs and other construction on this small farm. ~58- Figure No. 25 This 56' x 72' dairy barn was recently constructed using native material consisting mainly of aspen and jack pine. The cash investment in this barn was approximately $1500, and the barn probably would never have been con- structed had the owner not been able to use readily available native lumber. Part of this lumber was cut from the owner's wood lot and part of it purchased from the Tanner mill at East Tawas. -59- 4] ‘. ' *o' ,_ is, n..-.

About that time hemlock lumber was in much the same position as aspen lumber is today. It was considered a very inferior wood and it is inferior in many respects to white pine which had been so abundant in the years just pre- vious to the time this silo was constructed. This silo has been filled every year for the past 50 years. The silage has kept in good condition and the lumber is still sound. With continued painting, using asphalt or creosote on the outside, it should last for another 50 years. Note the crib construction and theuniform width of the boards and also the freedom from cracks. -51- f H5 w ,—. Ni '--' 9'15“ 392‘ :3... "f; {'5’ r. ' ‘ .. «L: ”Q‘s“? - u '2’. J! 01,-." D c A, - .4!

It has been painted once since it was constructed. ~64- Figure No. 51 This 36' x 50' barn was constructed by another Farm Security Administration client for a cash outlay of about $900. The lumber for this barn was obtained partly from the owner's woodlot and partly from the Huron National Forest. The Farm Security Administration supervisor for this region says that before this barn was constructed, the owner was housing four cows and a like number of young stock in an entirely inadequate 16' x 24' barn, without feed storage, and the sales per cow for the year probably did not exceed $50. During the first half of the year after building the new barn, the owner was milking twelve cows, had about 18 head of young stock and the barn had adequate space for storing all required feed and bedding. Under these condi- tions, the income per cow was almost double what it had been previously. -65... .‘\ .— I ' :3 .2"- Figure No. 52 Another use for native lumber. These calf stanchions are constructed of cedar poles, but there is no reason why other species of native lumber could not be used for similar purpose if they were first preperly treated with some preservative and kept reasonably free from moisture. -66— EXPERIMENTAL CONSTRUCTION Since most of the prejudice against aspen is due to small dimension and relatively low grade lumber, it seems desirable to give some serious consideration to types of construction in which the sizes and grades of available aspen lumber could be used most profitably. A high per cent of the aspen trees ready to be har- vested in the cut-over area of Michigan are under six inches in diameter and the saw logs from these trees will vary from eight to twelve feet in length. The accepted practice is to saw these small diameter logs into narrow one-inch boards or into two-inch by four-inch dimension lumber. Most standard designs for farm building construction are adapted to the use of this small dimension lumber. However, it is almost always used in conjunction with commercial materials such as flooring, siding or roofing. The sugges- tion that this native material be used exclusively for some low cost type of construction that would be practical for farmers in the cut-over area is a wide departure from recognized construction practices. However, when such a prOposal was made, a type of construction known as "crib" construction was suggested as having possibilities. This particular type of construction was used quite extensively before the steel and reinforced concrete era for the walls of grain elevators and for storage binsfiwhere a high degree of resistance to lateral pressure was desirable. .A crib constructed silo is shown in Figure 27. This type of con- struction has also been used for rough floors of various -57- types of structuresobut to use it for finished floors, walls Iand roof with neither an interior or exterior covering seemed extremely questionable. Per haps no further study would have been made had it not been for the critical farm housing situation in the cut-over area and the need for buildings requiring an absolute minimum of cash investment. In view of these facts, additional studies were made on the . practicability of using crib construction for such buildings. The advantages of "crib" construction are: 1. It is adapted to small dimension lumber manufactured from small diameter logs. 2. Only one size (cross-section) dimensioned lumber is required for any building. 3. Random length lumber reduces waste. 4. No skilled labor is required for construction. 5. No commercial building materials are required except nails and even these could be replaced by wood dowels in extreme cases. 6. Has greater insulating value than standard frame construction. 7. Has greater strength and rigidity than standard frame construction. The disadvantages of "crib" construction are: 1. More lumber is required per unit of area enclosed. The per cent increase will depend upon the type of construction used for comparison. 2. It is difficult to obtain smooth surfaces free from cracks unless carefully sawed or planed lumber is used. Specifications for a crib constructed grain elevator are given in a text book, "Walls, Bins, and Grain Elevators" written in 1919 by Milo s. Ketchum as follows: (26) -68- "The bins shall be constructed by planking in courses laid as follows: All walls shall be laid up plumb and true, forming square corners in the bins. Each course of planking shall be securely nailed with 50d wire nails 4%" long, said nails not exceeding 22 to a pound. At all interior crossings two nails shall be driven in each end of each piece of plank in the 4" and 6" walls. At all outside crossings five nails shall be driven in each end of each plank crossing the wall and four nails in the’ plank at right angles to it. The intermediate nails shall be spaced and staggered. At the base of the walls and for 11' -o" in height the nails shall be spaced not to exceed 14" centers, and for each additional 11' -0" in height the distance apart may be increased 2". The heads of the nails shall be well bedded in the wood." Another reference to the use of crib construction for grain storages is quoted from Farmers' Bulletin No. 1656, "Farm Bulk Storage for Small Grains." "In the crib type, the walls are built up of 2" lumber laid flat and spiked tOgether, the width‘ being determined by the height of the structure. For building 24 feet or less in height, 2" x 4" lumber is used. In walls 24 to 40 feet high the lower 16 to 18 feet are usually build of 2 x 6" material. The crib type of framing is preferable when the storage capacity exceeds 10,000 bushels. A metal clad farm elevator of this type of con- struction costs no more than a baloon type ‘ building of the same capacity would have cost." (25) Following the basic specifications for "crib" construc- tion as outlined by Ketchum, a small experimental building was constructed of 2" x 2" basswood taken from the Sanford woodlot at Michigan State College. Basswood was used in place of aspen for most of this building to avoid delay7 since the aspen originally requested was not as yet avail- able. In many reSpects, basswood is similar to aspen and it was decided that most preliminary observations could be made by using basswood. .The factors upon which preliminary observations were to be made are: 1. General construction procedure. 2. Methods of closing the cracks between mis-sawed boards. 3. Dimensional variation in the building owing to expansion and contraction of the lumber with changes in atmospheric humidity. A photograph of this first experimental building com- pleted except for the door and window is shown in Figure 55. _ This building was constructed for a portable tool shed to be used by the Forestry Department of Michigan State College. The skids are cedar poles; the floor is composed of three different woods: aspen, balm of Gilead and basswood. The small amount of aspen and balm-of-Gilead available was used in the floor since it would be more rapidly subjected to deteriorating influences and evidence of decay could be more readily detected. One-half of the floor of each species was painted with creosote and the other half used without treatment. The treated lumber was painted on all four sur- faces as it was nailed in place. As construction with the side walls progressed, it became increasingly evident that one of the most serious objections to using unplaned, rough-sawed lumber was the irregularity in dimensions, and particularly the difference in thickness of the individual boards. This is not a criti- cism of the species used but of the method of manufacturing the lumber. One of the first attempts to compensate.for minor variation in the thickness of the 2" x 4" was to paint the tOp surface of the thinner one with a coat of heavy white lead paint or aSphalt paint. This might have been practical if sufficient time had been given for the paint to dry, but as succeeding layers of 2" x 4" were nailed in place, the paint was forced from the cracks. This method of attempting to fill the cracks between the 2" x 4" was discontinued in favor of laying 4" strips of heavy asphalt paper over the thinner 2" x 4". This method seemed to be satisfactory and was used for the re- mainder of the building. See Figure 34. This building was constructed in the Agricultural Engineering laboratory during the summer of 1942 and was taken to the Forestry woodlot in the fall of that year. Observations were made at various times during the winter and the following summer to determine any variations in the dimensions of the wall owing to shrinkage or swelling with changes in atmospheric moisture. No significant variations were observed. It is entirely possible that the space between the 2" x 2" members oi'the wall compensated for any changes in thickness of the lumber. Although at no time were the open cracks completely closed by the swelling of the wood. Insufficient time has elapsed since this building was constructed to make any predictions as to its ultimate dura- bility. There is no evidence after three years of exposure to indicate a rate of deterioration more rapid than would be expected of other wooden structures. -71- Figure No. 55 An experimental building made of crib constructionj using 2" x 2" material (mostly bass-wood).

A SMALL HOUSE MADE FROM SCRAP WHITE PINE LUMBER BY USING CRIB CONSTRUCTION As a result of conferences with various individuals regarding the use of native lumber and the possibilities of using crib construction for various types of farm build- ings, the small house shown in Figures 55A, B, C, and D was constructed. This small house is particularly interesting. The outside walls, floors and interior partitions are constructed entirely of scrap lumber from a sash and door manufacturing plant. The cost of this scrap lumber was $60 and the owner of this building estimates that the total cost of material for the entire house was less than $550. Although the con- struction of this house was not undertaken as a definite part of this project on experimental construction, it was inspired by the project and built while this study was being made. Naturally this house was carefully observed during and after the construction. The white pine blocks, of which the main part of the house was constructed, are approximately 1" x 5" in cross- section and of random length from 4" to 16". The material was waste from kiln dried stock, but no effort was made to control the moisture content of this lumber as it was being used. However, the outside walls were painted with a penetrating oil as the work progressed. The outline for the outside walls and partitions was marked on the concrete floor slab and 1" x 5" boards were bolted to the concrete as a nailing base for the successive -74- layers of block. See Figure 558. It was necessary to build all partition walls at the same time since all inter- secting walls are tied together by courses of overlapping blocks. See Figure 550. Some additional precaution was taken in selecting blocks for the outside wall for the purpose of breaking joints properly and to find pieces with clear faces for the outside surface. It was not particularly difficult to keep the walls straight and plumb owing to the fact that the blocks were uniform in width and if all edges of the blocks were flush, the wall was reasonably true to line. As an extra precau- tion, the walls were checked every few courses for any error that might tend to become cumulative. Door and window openings were provided by building the wall to proper height and then letting the ends of the blocks overhang to be sawed off later when the door or window frames were inserted. No record is available of the actual time required for constructing this house since it was built during spare time while the owner was working. The owner estimates that a similar house could be constructed in less time than would be required for standard frame construction owing to the fact that no extra labor is required for sheathing or siding and that the time could be still further reduced by using longer material. It certainly seems reasonable to believe that if a house could be so easily constructed of thin, short blocks of uniform cross-section that it would be even more simple to construct a similar building using 2" x 4" pieces, providing these 2" x 4" could be sawed to uniform cross-section. There was some question as to the amount of swelling which might be eXpected in the outside walls owing to ab- sorption of moisture and the damage which might result in cracked plaster and cracks around windows and doors. There- fore before any interior finish was applied to the outside walls, measurements were taken over a period of several weeks including extremely humid and extremely dry weather to determine any variations in the height of the outside walls. These measurements were taken by driving a nail into the wall near the ceiling at a given distance from the floor and measuring at intervals the distance between the floor and the nail. When no significant change was observed in the height of the wall, the original plan of applying the insulating lath over furring strips was discarded and the lath nailed directly to the interior surface of the wall. As an extra precaution against moisture, the inside surface of the outside wall was painted with asphalt paint and 50-pound asphalt paper applied before the lath was nailed directly to the wall. At the present time, after the house has been lived in for three years, there is no apparent indication of defects which could be contributed to shrinkage or swelling of the walls. See Figure 55D. -76- Figure No. 55A Figure No. 55B This attractive and livable house was built in 1941 at a cost for material of approximately $550 by using scrap soft pine lumber and crib construction. -77- Figure No. 350 Detail of wall construction for house shown in Figure 55A.

This would be particularly true for deep bins which appear to be more practical than shallow bins from the standpoint of handling grain from a centrally located vertical elevator. The following photographs show the construction of a crib type farm granary in which 2" x 4" yellow pine was used for all outside walls and bin partitions. The original gra- nary (without the lean-to additions shown in Figure 56) was 50 feet square and 20 feet high, divided into bins 10 feet square. This granary holds approximately 12,000 bushels of grain, most of which can be handled by the vertical elevator through spouts connecting each bin with the bottom of the elevator pit. By substituting standard frame construction for the crib construction, it would have been necessary to use 2" x 14" studs,l2" on center or material of equivalent strength sheathed either outside and inside or double boarded on the outside. This type of construction would require 52 board feet of lumber for each square foot of wall against only 48 board feet for crib construction. While it is true that smaller dimension studs could be used if the walls were adequately braced, a higher quality lum- ber used was accurately dressed to prOper dimension. However, -79- the simplicity of crib construction and the fact that it is adapted to the use of short length and relatively low grade lumber diould make it more pOpular as a method of constructing certain types of farm buildings. Note: Computations for determining the required strength for the walls of a grain bin 10 feet square and 20 feet high were based upon Janssems formula: wR (1 - 1 ) in which T ( 1th ) ( 2.7181“ ) Lateral pressure at depth h. Weight per cubic foot of grain. Hydraulic radius of the bin. Coefficient of friction of grain on bin walls. Ratio of lateral to vertical. Depth of grain. fixttwét“ Figure No. 56 The central portion of the building is a 10,000 bushel granary made of crib construction. See Figures 57 and 58 for details of construction. -80- Figure No. 57 All bin partitions are tied into outside walls by overlapping alternated layers of 2" x 4", making an extremely rigid build- ing. Figure No. 5B The maximum value of crib construction is in deep bins which would require heavier construction members and extra bracing, if ordinary construction was used. The owner estimated that the cost of this granary is no greater than the cost of one of similar capacity using standard stud construction. C‘ J .r'. I” slid- E.

DIMENSIONAL VARIATION IN THE MANUFACTURE OF NATIVE LUMBER As a result of the difficulties encountered in handling poorly manufactured native lumber, it seemed desirable to obtain additional data on the factors contributing to poor quality lumber as a basis for making corrective suggestions. 7 One of the primary factors contributing to poor quality is improper sawing resulting in a large amount of off-dimen- sion lumber. The extent of this defect in representative samples of native lumber is shown in the following tables. 'The data for these tables were obtained by visiting local saw mills and measuring samples of lumber produced in these mills. Figure 59 indicates the dimensional variation within individual pieces of 2" x 4" jack pine and shows the per cent distribution of pieces with the same variation of mis- manufacture regardless of actual dimension. For example, the chart shows that 24 per cent of the pieces measured varied 2/32" between their maximum and minimum thickness, but the actual dimensions of the pieces are not given. Figure 40 shows in addition to the dimensional varia- tion the relationship between actual dimensions and nominal dimensions as indicated by the base line Which represents a thickness of two inches. For example, the first board re- presented by the bar at the extreme left of the chart varied in thickness from I 29/32" to 2 2/52". The second board shows no variation. The third and fourth boards vary from 1 30/52" to 2". -85- Figures 41 and 42 show similar data for one inch boards of aspen, and beech and maple lumber. It is not difficult to visualize the discrepancies which would occur in any building where such lumber is used. The second factor contributing to poor quality lumber is careless piling. Most small saw mills, many of which are portable, do not have yard facilities nor adequate labor for prOperly piling the lumber as it is sawed. Therefore, most - of it is improperly piled at the mill or is taken by the owners and carelessly piled as indicated in Figures 45 and 44. Lumber properly piled is shown in Figure 45. This pile was made at the College saw mill and for convenience was piled among trees which is objectionable from the stand- point of air circulation through the pile of lumber. Improperly piled lumber. Figure No. 44 Unless this lumber is used soon, it will gradually deter- iorate owing to stain and decay. ‘7 9, — ...

Most of the service buildings and many of the dwellings are so near total depreciation that they have no actual physical value, but are still standing, if somewhat precariously, and are still used for storage and shelter. The younger farmers particularly are aware of the need for better buildings, more carefully designed to meet the needs of their type of farming and are willing to c00perate in most any way to get them. They do feel that the present prices of local building materials are too high and freely express their unwillingness to build if they have to pay these prices. In most instances, they cannot afford to buy standard materials. One farmer admittedthat he might have to pitch a tent because his present house was almost unlive- able and he could not afford a new one of standard construc- tion. 0n the other hand, they cannot afford not to have adequate buildings. Every year losses are sustained which could be prevented and the entire community is handicapped owing to blighted moraliI For example, one farmer stored some beans in one of the typical storages found in this area and lost the entire cr0p valued at more than $200. A new building to house his entire grain crop could have been constructed for less than $200 by making use of native lumber on his own farm. A young, recently married couple were about ready to leave a ~86- farm in Gladwin County. The husband was interested in farming and wanted to stay but the wife was fearful of losing their friends because she was ashamed to invite them to her "shabby" house. Perhaps a house similar to the one illustrated in this report would have solved the housing problem of these young peOple. Such houses when constructed of native lumber are entirely practical and would do much to keep our desirable young people on the farm and to stimulate a higher standard of living in their communities. In addition to the need for new buildings, an extensive program for remodeling and repairing existing structures is imperative. It has been estimated that 850 board feet of lumber will be required annually on each farm in Michigan to meet this need. The demand for lumber in the cut-over area may be even greater than this estimate, owing to the fact that the farm buildings in this area have been neglected for so long. If it was difficult for these farmers to obtain standard lumber for farm construction before the present war, their plight will be even more serious when building restrictions are lifted to prepare the way for an enormous program of post-war construction. One answer to this problem, and it seems a most logical one, is to make better use of our supply of native timber, particularly aSpen and jack pine in the cut-over areas of Michigan. This study shows the volume of aspen alone is increasing at the rate of 66,250,000 board feet annually in the stands which are 25 years of age or older. -87- Even though a large part of the available supply of native lumber has been used to meet war requirements, as would seem reasonable, it is even more desirable to con- serve and properly utilize the remainder where it can be used.most economically. This would appear to be on the farms and in the rural areas where this lumber is available. The prejudice against aspen as a building material that has consistently retarded its use may be partially overcome by the expanded utilization of this wood for war purposes. In addition to this stimulating influence, sufficient evi- dence has been presented here to show the desirable proper- ties of both aspen and jack pine which alone should warrant their extended use. However, if the use of such native lumber is to be increased fast enough to furnish any appreciable degree of relief in the anticipated post war building program, its advantages will have to be demonstrated in a more authentic manner by all interested agencies. Some consideration should be given to demonstration buildings constructed c00peratively by the Michigan State College Extension Service, the State Conservation Department, the Farm Security Administration and others, to show that the use of‘native lumber even of low grade is practical and to call attention to the struc- tural details that will insure it greater durability. In this connection, it is interesting to note that the State Conservation Department offered to furnish the lumber for a number of such demonstration buildings. -88.. In addition to encouraging farmers and local builders to properly use all species of native lumber, some effort should be made to obtain a higher quality of manufacture from small local mills. The disadvantages of using rough sawed, poorly dimensioned, warped,stained and knotty lumber should be more or less obvious to anyone whether or not he is familiar with all the details of building construction. It is difficult to persuade builders to use poor quality lumber even at a reduced price or to encourage farmers to haul their logs to a local mill that will only "butcher" them. It is equally difficult to arouse much enthusiasm on the part of local mills when the market for their pro- ducts is so uncertain. The most common defects found in locally manufactured lumber can be corrected by proper sawing promoted through an effective educational program on the same basis as suggested for promoting the proper use of native lumber. However, such programs are inadequate to insure a constant reliable source of native lumber. Additional equipment7such as edging and trimming saws, planing mills and in some cases even dry kilns will be required. Few local mill Operators have sufficient capital to finance such an outlay of equip- ment. Although it is not in the realm of this study to make specific recommendations, it seems desirable that finan- cial aid in some form should be available to local operators who show evidence of ability and interest in undertaking such a project. Additional studies should be made as to the most effective methods of providing this financial assistance. The c00perative association formed in Alcona County by the Farm Security Administration for the sale of pulp wood is an effective possibility that warrants closer observation. In the report on the successful deve10pment of several forest products COOperatives in the United States, the author gives a brief summary of one. "Management plans are made for each woodland; farm building plans are prepared, and require- ments in terms of trees are computed; trees are marked and cut on order to fill the bill for lumber; and then the lumber is seasoned and processed in the final stage for use. At the present time, 26 farm buildings are scheduled; ll structures have been sawed out by portable mills since March 18, 1941, involving 70,000 board feet of native lumber (mostly oak and cottonwood); and five buildings are now under construction. Farmer members are delighted with the low-cost, high quality lumber which is making possible new construction and farm building repairs needed for many years." (15) In addition to privately financed mills and cOOperative associations, there is a possibility of combining small local mills with established retail lumber yards.‘ This arrangement would seem to have certain advantages. The retail dealer through his financial interest in the mill could maintain quality lumber standards and a more constant and reliable source of supply. Some farmers would patronize the retail dealer through their contacts with the mill who might not otherwise do so. CaSper Bloomer, the County Agent in Alcona County, cites several instances where farmers now have adequate buildings owing to the fact that they used native lumber for all dimension stock and by so doing saved enough to buy all the other materials, such as cement, siding, shingles, paint, hardware, electrical wiring, etc., which they would not have been able to buy had they been forced to buy all their lumber from the retail yard. To avoid some competition between local mill and retail yard, an arrangement could be worked out whereby the mill produced only dimension stock. Another reason for this arrangement is the difficulty of producing high quality one-inch lumber from the small legs which most local mills would be required to handle. Rather than to pile this lumber improperly and let it deteriorate, the retail yard should haul it to their yard where it could be properly piled, seasoned to use and, if necessary, re- sawed to dimension. Lumber dealers, particularly those in the cut-over area, should realize the need for more adequate farm build- ings in their communities. The dealers themselves would profit by living in a more tidy and prosperous community. They are the logical ones to promote better buildings, owing to their position as lumber dealers and servicing institutions for farm buildings. Also, they should realize that they would be increasing their own sales of supplemen- tary lumber and other building materials such as cement, hardware, shingles and other materials of similar nature by promoting the sale of a better grade of‘native lumber. SAWDUST AND PLANER SHAVINGS FOR FARM BUILDING INSULATION The insulating value of dry sawdust or dry planer shavings has long been recognized and it compares favorably with commercial insulating materials. .From unpublished data compiled by the Forest Products Laboratory, the use of these materials might well be increased. The primary consideration is to obtain dry material and use it in such a way that it will remain dry. It is not the intention here to propose that sawdust or shavings be substituted for commercial insulation in all cases even in this cut-over area where low cost housing is being pro- moted. However, there are numerous buildings including the house, vegetable storages and livestock buildings that need additional insulation and it seems logical to suggest that local materials be used wherever practical. Interest in sawdust concrete is maintained by periodical reference to its merits as a lightweight concrete for the floors of livestock buildings, particularly for poultry houses. If the right kind of sawdust is used, it is possible to make a lightweight concrete having considerable strength. Samples of this material have been observed in small blocks which appeared to have possibilities as a wallboard. Its use is mentioned here because previous investigations have shown that jack pine and aspen sawdust are among the few types that can be satisfactorily used in sawdust concrete. In most sections of the cut-over area it is difficult to obtain adequate supplies of straw for bedding farm ani- mals. In these areas it is possible to use sawdust and shavings as a satisfactory substitute. The above suggestions for using sawdust and shavings apply particularly to the small mills where the supply of these materials would not be commercially important. For -92- larger mills the expanding wood plastics and related industries might be a more profitable market. THE USE OF SMALL DIMENSION TIMBER, EDGINGS AND TRIMMINGS It is usually unprofitable to saw small dimension logs into dimension lumber, but it might be profitable to saw such logs into stock that could be resawed into slats for crates and boxes. Additional material for this purpose might be salvaged from the edgings and trimmings. To supplement the manufacture of crates and boxes for which there is only a seasonal demand, the small logs and salvaged stock could be converted into wooden:ware, rustic furniture and novelties. There are at the present time many such small industries in the cut-over area that furnish part-time employment for the local farmers and others. FENCE POSTS AND FIREWOOD In addition to the actual by-products of the sawmill for which suitable markets could be develOped, there are timberland by-products which should be harvested to make way for more desirable young growth in some stands and for good woodlot management in others. Where there are suitable stands of cedar or some desirable hardwoods, the sale of fence posts should be encouraged. One of the reasons for retarded livestock deve10pment in some cut-over lands is the absence of suit- able fences. It might even be practical to install inexpen- -95- sive equipment for treating of nondurable woods to increase the life of fence posts cut from them. In every timber stand there are crooked, multiple- branched trees that might better be converted into firewood or cut into bolts for pulp wood or excelsior. In addition to such trees, there are large limbs and the slabs from saw logs that can be and usually are converted into firewood. The most discouraging angle is that little attempt is made to market these forest products in an orderly and profitable manner. But, the development of such markets for all timberland and sawmill by-products is as much a part of the problem of promoting the use of native lumber as the establishment of markets for the sale of the lumber itself. -94- CONCLUSION 1. There is a definite need for more adequate farm buildings in the cut-over area of Michigan. The investment in buildings on farms in this area is shown in Figure 8. The depreciation on this investment for a typical county such as Midland amounts to approximately $150,000. Yet, during the years preceding World War II, the money spent on farm buildings was insufficient to pay for this deprecia- tion as indicated in Tables No. VI and No. VII. 2. Personal interviews with farmers, county agricultural agents and farm security administrators leave one with the impression that this delay in farm building improvement may be contributed partially to the high cost of lumber imported from other states. For the report on these personal inter- views, see pages 47 to 66. 3. That native lumber, and particularly aspen lumber,. can be and is being used by the farmers of the cut-over area for their buildings is amply demonstrated by photo- graphic and other data collected during this study. Invar- iably the cost of these buildings is below the estimated cost of similar buildings erected with lumber obtained from the usual source. 4. The physical properties of aspen as discussed in this report (Pages 38 to 46) indicate that it is satisfactory for most farm building purposes. Present indications are that aspen will last for thirty years if used for such purposes as framing lumber, siding, sheathing, rafters, roof boards or -95- for other purposes where it is not subject to moisture. 5. Aspen timber is available to farmers in Michigan and discrimination against this readily available native wood as a source of potential lumber will decrease with expanded use for building purposes. 6. State and Federal Governments are anxious to find a market for the continually increasing volume of aspen which is reaching maturity and marketable age each year in state and national forests. The Michigan Department of Con- servation expressed a particular desire to cooperate with farmers in the cut-over area to promote the use of aSpen lumber for farm building construction. 7. The quality of locally sawed native lumber must be improved if it is to compete successfully with commer- oially produced lumber. The typically poor quality of native sawed lumber is indicated by the dimensional varian tions in 2" x 4" stock and one-inch boards shown in Figures 59 to 42. Several lumber dealers in the cut-over area rather grudgingly admitted that they would handle native lumber in their yards if the quality of this lumber was materially improved. 8. Additional studies are needed to: (1) encourage the production of better quality native lumber by improved methods of sawing and handling of this lumber, (2) develop . methods of construction adapted to the use of native lumber. 9. The building industry of the entire nation is now engaged in trying to promote a program for farm building improvement. The use of native material and particularly aspen seems to fit definitely into this program. ~96- COMMON AND SCIENTIFIC NAMES OF TREES NATIVE TO MICHIGAN WITH SUGGESTED USES SPECIES SUGGESTED USE IN FARM BUILDING CONSTRUCTION Ash, black (Fraxinus nigra) Ash, white (Fraxinus americana) ASpen, pOpple (POpulus tremuloides) Balm of Gilead (Populus balsamifera) Balsam (Abies balsamea) Basswood (Tilia glabra) Beech (Fagus grandifolia) Birch, yellow (Betula lutea) Butternut (Juglans cinerea) Cedar, white (Thuja occidentalis) Cherry, black (Prunus serotina) Cottonwood (Populus deltoides) Elm, rock (Ulmus racemosa) Elm, slippery (Ulmus fulva) Elm, American (Ulmus americana) Hemlock (Tsuga canadensis) Hickory (Hicoria spp.) Locust, black (Robinia pseudoacacia) Studs, interior finish Framing Sheathing Sheathing Sheathing Siding, sheathing, trim, cupboards Flooring, framing Studs, sheathing, flooring Finish, sheathing Shingles, siding, silos Finish, sheathing Sheathing Stall flooring, framing Sheathing, framing Sheathing, framing Sheathing, framing Sheathing, framing Sills, stalls -97- COMMON AND SCIENTIFIC NAMES OF TREES NATIVE TO MICHIGAN WITH SUGGESTED USES (CONTINUED) SPECIES Maple, hard (Acer saccharum) Maple, soft (Acer rubra) Oak, red (Quercus borealis) Oak, white (Quercus alba) Pine, jack (Pinus banksiana) Pine, red, Norway (Pinus resinosa) Pine, white (Pinus strobus) Spruce, white (Picea glauca) Sycamore (Platanus occidentalis) Tamrack, (Larix laricina) Walnut, black (Juglans nigra) Willow, (Salix nigra).
