Vol. 4, No. 6 LOAM FOR CONTROL With the advent of the present Chairman of the Greens Committee a t Belmont Spring Country Club it was decided to investigate ways and means of heating loam used f o r topdressng to destroy the weed seeds. While three years work has not produced a method entirely f r e e f r o m faults, very definite results on weed control have been demonstrated and the writer has become thoroughly converted to the practice of heating' loam f o r weed control. One of several troubles at Belmont Spring, four years ago, was t h a t of weeds in the Greens. Probably Chickweed was the worst, at any rate that received the most publicity; however Plantain, Dandelion and Shepherds Purse were all too numerous. The looks of more than one Green a f t e r these three weeds had been dug' out is still a vivid memory. The operation bordered on the heroic but the membership was most tolerant and bore with the new Greenkeeper, despite the f a c t t h a t he had reduced some of the putting surfaces to shell torn terrain. As f o r the Chickweed, the high point in number of plugs in one Green alone would undoubtedly, if stated, set the writer up as a competitor of Baron Munchausen. It was not difficult to determine t h a t the chief source of weed infection was our top-dressing. Investigation of our loam brought to light t h a t aside f r o m this drawback it was ideal f o r our conditions. To work up any of our waste land into a compost of equally good physical condition as our purchased loam meant a long, slow, expensive program and when we had reached t h a t point, we had no guarantee t h a t our weed contamination would be any less, f o r our waste land is full of Chickweed which is as resistant to destruction through cultivation as any weed we have, clover not excepted. Chemical extermination did not nor does it now present a very happy solution. A cure which does not begin somewhere near the source of the trouble is, at best, a makeshift. To arrive at this point took some time. Next ways and means f o r heating loam were investigated. Dry heating by piling loam over a fire, much as sand is dried, did not seem to fill the bill. Wood is usually used for fuel in this method and under our conditions the fuel cost would be prohibitive. Also our experience had not been too conclusive of its economical effectiveness. Labor costs are high and there seems to be too much chance f o r uneven heating unless closely supervised and checked through frequent temperature readings. Subsequent experience proved t h a t a mass of loam is surprisingly re sistant to heat and t h a t it is almost impossible to heat it uniformly if there is any depth to it. It is also well known t h a t dry heat is much less effective in destroying seeds than is moist heat. Dry heating was ruled out and we turned to steam which ¿eemed the ideal medium f o r obtaining the desired results. No matter what method we looked into f o r getting- steam into a given amount of loam our stumbling block was boiler costs. Our situation is such, both as to location and legality, that we cannot run a boiler which is not capable of passng the Massachusetts Standard, and three years ago a second hand boiler which would do this had a first cost t h a t prohibited asking f o r an appropriation f o r the boiler alone, not considering the other items which would have run the installation cost well over $1,000. We believed t h a t if the moisture content of loam was normal, a given amount of loam exposed to sufficient heat would generate steam which would percolate through the loam and destroy the weed seeds. To get this heat we decided to use oil as fuel. As there is always the possibility of s a t u r a t i n g some of the loam with oil because of f a u l t y combustion we had to apply the heat indirectly Our set-up was a boiler plate box approximately three feet deep with a drop side f o r unloading and a slip cover. The capacity was one cubic yard. This box was put on a six inch fire brick wall with a wall cf common brick about f o u r inches away f r o m the sides of t h e box and closed in a t the top. The drop side was not bricked in and the fire brick wall was vented to allow the heat to escape and r u n up around the sides of the box between it and the common brick. Heat was furnished by a Hauck Burner. This is an oversize blow torch which throws a 30 inch flame, generating 1800 degrees of heat, using either kerosene or f u r n a c e oil for fuel. The burner was set up to throw its flame through a 4 inch opening left in the fire brick into the chamber beneath the boiler plate box. In a surprisingly short time this chamber became a roaring inferno f n d apparently we had heat enough f o r all our needs. Until we learned to respect this heat, shoes, gloves and clothing would smoke and char when we stood too near the box f o r only a very short time. We went to work optimistically. Dry, moist or soaking wet, it made no difference, we could not get uniform heating through the loam. With the box full, half or quarter loaded the heat would travel unevenly. A spot would show 190 degrees and a few inches away the loam would not be hot enough to be uncomfortable to t h e bare hand. There was too much handling of loam, too much time lost standing around waiting for the loam to heat; in fact, our first attempt was most unsatisfactory, but not a total failure, f o r we learned t h a t loam heated to 190 degrees with a normal amount of moisture in it before heating will be practically weed free. The test was of sufficient length to bs conclusive. A box was divided in half, unheated loam in one side and heated loam in the other. This was set out of doors f o r three months, watched to see t h a t it did not become too dry, and at the end of t h a t time the difference in numbers and types of germinated weeds was so marked t h a t those of us who had been skeptical up to this time were convinced t h a t heating loam to kill weed seeds was of sufficient value to w a r r a n t f u r t h e r investigational work. A f t e r taking stock of our first years •work we found that we had convinced ourselves of the soundness of the practice and t h a t we muat work up some scheme of keeping a continuous flow of loam passing through indirect heat of sufficient temperature to do the job. In 1931 we set up what is our f u n d a mental principle. A continuous flow of loam heated uniformly to the necessary temperature, by indirect heat. This set up is two sections of 10 inch cast iron pipe, 18 feet in total length. Inside this pipe is a 9 inch screw conveyor of the same length hung in three bearings, the whole being supported a t the ends and in the middle, with a pitch of 10 to 12 inches. Probably the pitch is of little consequence as the screw conveyor is slung off center in the water pipe, leaving only enough clearance to keep the flanges of the conveyor f r o m rubbing on the bottom. The center support is of the bridge type, allowing p a r t of the Hauck burner flame to shoot through and acting also as a baffle forcing the upper p a r t of the flame around the pipe. The upper end of the pipe is closed in with sheet metal with a hopper on top to facilitate loading. The cast iron pipe is bricked in f o r three-quarters of its length starting f r o m the lower end. Better design of the upper support would permit bricking in of the pipe f o r its entire length but in order to set our Hauck burner in the proper position it was necessary to leave the upper part of the pipe unbricked. For a cover we salvaged boiler plate f r o m our box of the previous year having it cut to the proper width. Our screw conveyor is driven by a one and one-half horse power electric motor through a reduction gear, chain and sprockets. By changing the ratio of the sprockets the speed of the conveyor can readily be speeded up or slowed down. The results f r o m the first year of this set iip were most satisfactory. Under normal conditions loam came through continuously and uniformally heated to 190 degrees, but when winds were strong or mid-day temperatures much below freezing there was considerable fluctuating in the temperature of the loam as it came f r o m the discharge end of the pipe. In 1932 we added another Hauck burner. Running one f r o m the upper end, as before, and shooting the flame f r o m the second one in the side about mid-way of the pipe. We were able to increase the speed of the conveyor appreciable, lowering labor costs and reducing t h e liability of jamming. Our heat jumped to a constant 200 degrees and we r a n through some 70 cu. yds. at a not unreasonable cost. The loam f r o m this 1932 batch has had a very thorough testing. We have used nothing else in raising seedlings of annual flowering plants which we g'row f o r a cutting garden f o r the Club House. We have potted up several hundred plants in this loam in addition to the loam in the flats where the seed was germinated. Obviously conditions in the hot bed were as favorable f o r t h e germination of weed seeds in the loam as the planted seeds but we have germinated just two weed seeds, both clover, and not over six grass plants. The grasses are noted because a f t e r t h e loam is screened we cover it with hay to keep it f r o m freezing before we run it through the heater. The upper layer of the loam must be filled with the seeds of wild grasses and the f a c t t h a t we have so few g'rass plants germinate is still f u r t h e r proof of the effectiveness of the heating. For our last top dressing of 1931 we were obliged to use unheated loam and the amount of Shepherds Purse present in all our Greens brings home once again the effectiveness of heating loam to destroy weed seeds. For our first year we r a n the conveyor in plain bearings, but this last year we fitted it with roller bearings. The upper one served both as an annular and thrust bearing'. We believe this to be important, f o r under operation there is a heavy t h r u s t load on the conveyor which if not properly taken up, causes undue wear and cuts into the efficiency of operation materially. The middle bearing, much to our surprise, gave us no trouble. We were unable to secure any definite recommendations on a special bearing to fit this condition so put on an ordinary annular bearing which r a n unoiled in a known temperature of 400 degrees and when examined this Spring was in very good shape. When the machine is set up next Fall we shall put in a new bearing, the expense f o r this being much less than to r u n the old bearing and perhaps have it fail in the middle of the work. Jamming may happen f o r two reasons. Rocks occasionally get in, but with the speeding up of the conveyor we found t h a t what few rocks did get in were run through without any serious jamming. Loading' the conveyor too heavily will also make it jam. Experience soon teaches the proper loading speed and our second year took care of this also without any real difficulties. The speed at which the conveyor can be r u n depends basically on the amount of heat inside the cast iron pipe. W h a t heat is actually needed inside t h e pipe to kill the seeds we do not know, neither do we know j u s t how long the loam should be in passing through the heat. We do know t h a t we have 400 degrees minimum heat in the hottest p a r t and t h a t the loam flows through in approximately two minutes, coming out a t 200 degrees. There is still considerable study to be made of the three factors, speed, heat and time of flow to bring them into the most efficient correlation. Our weakest point is that our set up is not permanent. Our loam shed is small with one side open. Seventy-five cubic yards of loam are put in, screened through a power screen and then out conveyor heater set up just inside the open side of the shed. A f t e r the loam has been run through we must t e a r down the set up to get our loam out easily. Our construction consequently is much lighter than is desirable. Our motor and reduction unit must be taken up at the end of each day's work, causing us some minor trouble in keeping it in perfect alignment. This coming year with our past experience to work from, we may be able to correct some of these minor weaknesses and improve upon the efficiency of the machine as a whole. Undoubtedly by now many readers have condemned the practice of heating loam because, " I t does something i n j u r ious to it." The field of micro-biology is not one in which we even attempt to enter, being satisfied to leave t h a t to men who have studied and trained f o r t h a t particular field of science. We are content to depend on their opinion, which is, t h a t if heating is injurious to soil bacteria it is of little consequence f o r the soil of the golf course is teeming with micro-organisms which will immediately correct a sterile condition of the heated loam, if such a condition does exist. Practically speaking, we have germinated a wide variety of annual flowering plants and have grown them along f o r two months or more in nothing but heat treated loam. The resulting plants are strong, healthy and vigorous. We are, therefore, convinced t h a t heating' loam, at least as we are doing it, has done nothing more to the loam than kill the weed seeds t h a t were in it. I have purposely omitted figures on labor costs and cost of building a conveyor heater. We have these figures, but as our original material was for the most p a r t second hand, the figures are Exclusive New England Distributors For: Premier Brand Pulverized Poultry Manure Rams Head Brand Pulverized V.

Our labor costs are not secret but it is our observation that maintenance figures when put before the public are wrongly applied and analyzed and so do harm rather than help. That this is so is a sad observation on the mental processes of us all; however I am straying f r o m the point. We do not believe that anything new or revolutionary has baen instituted: if this report of our experiences is of help to anyone we are more than satisfied. We are not interested in debating the pros and cons of heat treating loam as a maintenance operation. We do believe, unreservedly, that for our conditions a t Belmont Spring' Country Club we are rendering a distinct service to the Club throug'h this maintenance operation, the cost of which is more than justified. We admit that the efficiency of the machine can be improved upon, but we do not claim perfection for it. The evolution of this practice and the development of our conveyor heater is in no sense the result of individual work. We are indebted, in particular, to the following; The Hacck Manufacturing Co., Mr. Harold Robie of Bellamy, Robie and Sargent who would have liked to build us a drag link conveyor but told us that our principle was sound and to stick to it; Mr. Malcolm S. Cate of the engineering department of the Hood Rubber Co., for much practical advice; Mr. Duncan Shenk for his friendly criticism; Mr. J . F. Buel who helped us, materially, in adapting the various parts into one workable unit; Mr. Osborn Bezanson of the Merrimac Chemical Co., for assistance in locating much of the material used, and, of course, none of this work could have come to pass without the co-operation. confidence and encouragement of Mr. F. D. Shenk, Chairman of the Greens Committee of Belmont Spring Country Club. Charles W. Parker. RHODE ISLAND FIELD DAY The third annual Greenkeepers Field Day was held at the Rhode Island State College and Experiment Station on May 23, 1932. Following registration, those present visited the experimental plats, where Dr. T. E. Odland and Prof. H. F. A. North explained the various plots and experiments being conducted on them. The old lawn plots, established in 1905, are still of much interest. Various new experiments with compost, the effect of different soil reactions on newly seeded R. I. Bent, arsenate of lead, etc. are also of interest. On the golf green plats, the plats of Yorkshire velvet, B. P. I. 14276, and Kernwood velvet attracted much attention, as probably the best plats at this time. Two series of seed production plats show that Rhode Island is a seed producing region, and that the experiment station is trying to help those who grow grass f o r seed production. Following lunch, Director B. E. Gilbert of the Experiment Station presided at the Grass and Turf Conference. President Raymond G. Bressler of Rhode Island State College welcomed the visitors to the campus, and announced that the College would offer a five day Short Course for greenkeepers this coming Winter, probably in February. He read a sample program for approval. Other speakers were R. Wallace Peckham for the Rhode Island Greenkeepers Association, Dean Adams of the College, Melvin Brightman in behalf of the seed testing department of the R. I. Dept. of Agriculture, and P r a n k H. Wilson, J r . who brought greetings f r o m the Greenkeepers Club of New England. The main address was presented by Dr. Howard B. Sprague of the New Jersey Agricultural Experiment Station. Dr. Sprague spoke on "Soil Conditions and Plant Growth". He pointed out t h a t this subject is not a single one nor is it easy to understand. It will be some years before we understand soil conditions. Practically everything we do to grass is effective through the soil; theref o r e it is very important. Get best system of management to manage soil to get best results. We look for sources of information—what is the best combination of soil conditions to bast grow grass? Dr. Sprague pointed out the differences between the soil in eastern United States, originally n a t u r a l forests, and the western soil, n a t u r a l grass land. The textures are similar, most obvious difference is in color, black soil in west, color due to organic matter, distributed f u r t h e r down in soil. Also differences in structure,, east f a i r l y light on surface, down some inches denser in struct u r e ; in west, more or less same structure all the way down, with good drainage. E a s t soil is usually acid, prairie soil neutral. Eastern soils are more deficient in plant food, poor in phosphorus, also lime; the n a t u r a l supply of potash is lower. Our soils are not naturally suited f o r grass production. The conditions in West are maybe not ideal, but they show the trend. Experiments show t h a t most grass roots are confined to the first inch, with a substantial development down to five inches, a little to seven inches. Grasses produce a new root system every year, starting when grass becomes green. The old roots are dying, begin to decompose, conditions must be right in soil f o r root development. Any accumulation of organic matter tends to lose its capacity for holding water, especially material not decomposed. How f a r should we go in changing soil textures? On fairways, we sometimes must take them as they come1, except on sandy fairways, where they can be topdressed' with clay soils. On greens, ideal is toward sandy loam. This is most likely to give best results. We cannot hope to get the organic m a t t e r con- tent same as prairie soils, but we should increase the organic matter content on greens. Bent grasses, even though tolerant of acidity, probably do best on soils not more acid t h a n 5.5 pH. On strongly acid soils the danger of i n j u r y to grasses is greatest. I t is wise to provide nitrogen in several f o r m s ; the solution of problem of supplying nitrogen is a compromise by supplying all forms, nitrate, ammonia, and organic N. Dr. Sprague showed and explained several charts picturing results of various experiments conducted by him in New Jersey. One experiment on the effect of adding organic matter to soil on w a t e r holding capacity and growth of g r a s s " showed t h a t all materials used increased t h e water holding capacity f r o m untreated soil, and also increased the top growth of grass, in both sandy and clay soils. The more thoroughly material has been decomposed, the better source f o r soil improvement. Layers of organics are very undesirable; if we can produce a blend of these materials ill soil, improvement will show. Peat moss is better composted unless it can be kept wet while decomposing. Following a short question period, the annual meeting of the Rhode Island Greenkeepers Association was held, with President Peckham presiding. The following officers were elected: Pres., Lawrence Hay of Agawam H u n t ; V. Pres., Thomas Galvin of Rhode Island C. C.; Sec., Woodworth Bradley; Treas., Martin Greene of Wannamoisett. Exhibits and demonstrations of sprinklers, putting green mowers, hand and power, lawn mowers, and other small equipment completed the day's program. This third Field Day was blessed with fine weather, a f t e r the two previous had plenty of rain. The cooperation between th^. State College and Experiment Station staffs and the greenkeepers of the State is a fine thing for golf in Rhode Island. Prof. John B. Smith tested many soil samples during the day. Dean Adams brought out the three rules f o r a successful public speaker-— to stand up, speak up, and shut u p ! We wonder where this "world's worst golf course" is, on which all the staff play.

AGAWAM HUNT At present we are topdressing our greens f o r the second time this season with compost. We have added to our equipment a power screen, which is a great help; also a five g a n g mower has been changed to a seven gang by adding two units. The greens are cut by power mowers, this being the third season, and are a success. Lawrence Hay, Greenkeeper. NEWS The Agawam Hunt, one of the oldest golf courses in the State of Rhode Island, has reached the stage where it is so well established t h a t few changes can be made in the n a t u r a l layout f r o m year to year. Yet we have never passed up the opportunity to make minor improvements whenever there is a chance to better the present layout. This year we have added a few more t r a p s and altered some of our greens. The third f a i r w a y received first attention; nearly an acre of sod was lifted in order to eliminate casual water which remained there a day or two a f t e r a heavy rain. The f a i r w a y was regraded and all the low spots filled, resodded, and topdressed. The brook in f r o n t of the 4th green has been filled in, and the contour of the sloping green built up so as to afford a better approach shot. The sixth f a i r w a y was topdressed and seeded. Being on high ground, we have put in a water supply. The 17th and 13th have had same treatment with water supply. NEW JERSEY FIELD DAY You are cordially invited to attend a field-day program devoted entirely to turf culture, a t the New Jersey State Agricultural Experiment Station on Monday, June 20, 1932. The meeting is sponsored jointly by The New Jersey State Golf Association, The New Jersey State Greenkeepers Association, and the State Agricultural Experiment Station. It is expected t h a t a large number of persons interested in producing and maintaining turf on lawns, golf courses, parks, etc., will be present. The program will begin at 3 P. M. (Daylight Saving Time) on the experimental turf plots cf the Agronomy Department at the College F a r m , New Brunswick. Each of the several hundred plots will be labeled, and visitors may draw their own conclusions as to the effects of the various treatments and conditions. A discussion of the field experiments will be conducted during the afternoon. At 6 P. M. the group will adjourn to the Hotel Woodrow Wilson where dinner will be served a t a cost of $1.50 per plate. A short evening program of talks on turf culture and a discussion of turf problems will follow. The July meeting will be held a t the Tedesco Country Club, Swampscott, Mass. on July 11th. To retain their standing, those who have not paid their dues f o r 1932 should do so this month. Send clues to the Treasurer, F r a n k H.

Hazlett, Bel-Air C. C. Reprinted f r o m the Pacific Greenkeeper The following is in answer to a number of questions asked of the Association president in regard to a very popular subject. Your Letter with its many interesting angles and suggestions in regard to old man Brown Patch received and would say no as to him being carried around on players' shoes, or at least not likely. He only thrives when the temperature is just right, and it does not seem at all probable t h a t t h e players wrould go to the trouble of accommodating the old boy to t h a t extent. And even if the players did pack it around on their brogues, there seems to be nothing t h a t can be done about the m a t t e r ; they have to get f r o m course to course and f r o m green to green, and the pest could be carried by bare feet as easily as not. The same thing applies to it being carried around on the mowers; the greens must be cut in the least amount of time, without benefit of fumigation. Possibly the idea is to carry around a bucket of hot suds to wash the machines every time a brown patch is seen. There are a lot of hokus pokus ideas floating around about this subject and I think it a waste of time to investigate many of them. Of course it is well to give all the evidence the once over. Since no one yet has demonstrated satisfactorily what the disease is all about, let us mark up a few f a c t s against the old boy t h a t we have seen come to pass and t h a t we know are true. When the weather is cold and windy he doesn't come around, neither does he leave his cave during nice warm growing weather. But let the temperature rise to about 80 or 90 degrees with the air still and a little fog or haze lingering on the horizon, and he sneaks in and bites where ycu aren't looking. Ordinarily the change can be very gradual, barely enough to be noticed. But if you look closely, you don't have to have very good eyes to see a few of the f a m i l i a r spots on some of your finest t u r f . From my own observations I would say t h a t it comes when there is least circulation of air, and it attacks the closest clipped grass the hardest. I t seems to settle down just as a heavy gas would do when there is very little circulation. It doesn't seem to be particular in its preference for high or low, and wet or dry spots. Night seems to be the time when the villian gets in his deadliest work, and he is particularly dangerous to a shaded green, but I would say t h a t this last is due to the fact t h a t the turf has not as much chance to recuperate in the sun's rays as does t h a t on an open green. We know t h a t brown patch and humidity hand in hand, and, because humidity is caused by the presence of atmospheric vapor under certain conditions, I cannot help but associate brown patch with something in a gasgeous form t h a t becomes active when conditions of temperature and atmosphere are j u s t right, conditions which allow a thin f o g to settle down. Of course the f o g and changes of temperature are all t h a t my senses were able to record. Humidity and the presence of gases associated with the disease do not always register to one not equipped with delicate instruments. Atmospheric conditions being matters over which we have no control let us accept them as they come, and put the greens in favorable condition to ward off any dangers t h a t may be present. Excessive water to keep the temperature down will not do, because the soil_, if of a heavy nature, will pack and algia will develop, thus putting the green in very poor condition to overcome anything. The sun and air must be allowed a chance to put in their good work, and this they cannot do_ if the turf is kept loaded with water, i t is better to spike the greens and put in enough sand, peat, and soil so t h a t the turf in the region of the roots will be of such a texture as to retain moisture; then the sun and air can do some good work. Of course there are extremes. The top must be kept a little moist; if allowed to get dry, no condition below would be of any help. This spiking and topdressing by all means should bs done in cool growing weather. If, a f t e r getting the green in good growing condition by the right application of nitrogen, potash and phosphoric, you a r e still subject to brown patch, you will find t h a t a green in this condition will respond very readily to treatments of mercury-chlorine compounds. It is stated that these ingredients, being deadly poisons, kill soil bacteria. I personally do not give a tinker's cuss if they do. If the greens are in a healthy condition they will overcome these ill effects to a great extent, and in the fall more bacteria can be added. The average golfer will never know that anything has been added or taken away, having enjoyed good golfing conditions throughout the summer. In the season when brown patch is most prevalent and it makes its appearance on two or more greens at the same time, do not err on the side of economy. For those greens which do not have it or have only a slight attack I would say cut down a little below the average full dosage. But of they have it in any noticeable amount, don't kid yourself, give it to them quick. When you analyze the whole mess and weigh the benefits of good greens for twelve months of the year against a summertime of questionable putting, it does not seem that $20 a year for the average green for brown patch medicine is prohibitive, does it? Especially not when you are giving old man brown patch a kick in the slats. All these other preliminaries such as topdressing to get the soil into the right texture for a healthy turf should be performed under any con ditions and should not be charged directly to the cost of handling brown patch. I would say that if the time is right for adding ammonium sulphate, mix this with the mercury treatment and water and you will get good results. The wet method seems to work best for me. It takes about 20 minutes for two men to treat a green. JUNE MEETING The June meeting was held at the Oyster Harbors Club, Osterville, Mass., on June 6th. Some fifty members and guests were present and enjoyed playing the very testing layout, scene of this year's State Open. Gross winners of the 18 hole medal turnament were: Michael McDonough, Oyster Harbors —40-47-87. James McCormack, Unicorn—48-40- 88. Net winners were: Tom Galvin, Rhode Island—94-18-76. Wm. McBride, Nashua—97-18-79. H. B. Cottelle, Barrington 101-20 -81. Mr. A. B. Hopkins, formerly Turf Specialist for the Armour Fertilizer C o m p a n v . is now with Goulard & Olena, Inc. of New York City. There recently reached our desk the very fine year-book of the Highland Country Club, Attleboro, Mass. This book gives a list of the club events planned for this season, and results of the main club tournaments the past season. A list of the members is included, as is also several of the important by-laws of the club. This book is of special interest in that it shows that one club at least of the smaller clubs actually plans ahead for the whole season. We believe that this idea could be copied with profit by many nther clubs whose tournaments are now being run in rather slipshod manner. A new practice putting green had recently been opened at the Highland Country Club, Attleboro, Mass. A new practice fairway is under construction at the Oyster Harbors Country Club. The Board of Directors held a well attended meeting on May 20, with President McCormack at Unicorn. The new Providence Municipal Course opened on May 1st with an attendance of 178 in pouring rain. Everett Pyle, greenkeeper in charge, reports crowds of over four hundred each Sunday since opening, with 422 as high mark to date. Frank Wilson reports two new tees built this past month at Charles River, the third, 60 by 20 width, and the twelveth, 70 by 25' width. R. L. Mitchell is now located at the Edison Country Club, Schenectady, N. Y. as greenkeeper, and W. F. Mitchell at Lake Sunapee Country Club, New London, N. H. as greenkeeper. With Samuel and Henry also working on golf courses this Summer, it seems t h a t Robert of Kernwood and his greenkeeping family could have an association all their own !
