Oakley If you intend to take up any feature of the vegetative planting of creeping bent this fall now is the time to start preparation. If you are a real novice and wish to make only a simple start you may do so with very little effort. While we think very highly of the vegetative method of producing creeping bent turf, we regard it as unwise for any club or individual to make even a very simple start with this method because he has been told it is the proper thing to do. Do not take the word of others. There are now examples enough close at hand so that you may see for yourself with relatively little expense or loss of time just what can be accomplished by this method in the making of bent greens. Really, when one stops to think of all the successes, it seems like a waste of good time to start in the simple way many have started—that is, by planting a row of stolons 100 feet long and waiting for enough material to develop to plant a green or a small practice green two years from the time the start is made; but it is a thoroughly safe way, and about all that is lost is a year’s time. If a year’s time means anything to you, take our advice and plant a nursery this fall sufficiently large to produce stolons for planting at least one green a year hence; or, if you wish to make even a shorter cut, buy stolons of a good strain from some reputable grower and start planting when the proper time comes this fall. Knowing that there are many who have heard of vegetative greens, as they are called, but who are still more or less in the doubting class or think they can not afford such greens all at once, and therefore wish to feel their way along, we have thought it might be well worth while to make some suggestions that will start such individuals in the proper way. To you who are in this class we assume that the die is east and that you have investigated the proposition to the extent that you have a very good comprehension of what it is all about and have decided to make a simple start in a garden or some other similar spot. Very well. Prepare a strip of your garden as you would for planting radishes or lettuce. Do this about the middle of August or the first of September. There are many strains of creeping bent; so it is up to you to choose one you like, or get the advice of some one who knows something about them. The Green Section will give you the names of several growers from whom stolons may be purchased. The selection of the strain is an important step. For a start such as you have in mind, a row 100 feet long is ample. So order your planting material on this basis. When the stolons arrive and you open the package you will probably find what looks like a rather rough piece of loose turf. Be ready to do the planting at once. Make a row or drill an inch deep, as suggested, and if your strip is not sufficiently long make as many more as you need, but make them at least 6 feet apart. After the rows have been prepared, tear the stolons or runners apart and lay them*in strands of 2 or 3 end to end, or with the ends lapping somewhat in the drill. After this is done cover with a little less than a half-inch of soil, and press down with the foot, oi’ you may use a roller, if you prefer. If the job is well done, parts of the stolons will stick up above the soil. They should not be buried completely. After planting, the rows should be kept moist until the new growth has made a good start. No cutting, dressing, or covering August 21, i OPBW/A/G TOP M/PPO/?.

The fastened supporting post extends 3 feet under ground and 3y2 feet above ground. The turning post, to which the periscope box is attached, is connected with the fastened post by means of a IX^-inch by 40-inch steel pin, and the abutting faces of the two posts are fitted with steel bearing-plates. The pin should fit loosely enough to allow for a little play so as to permit of ease in turning the box. The periscope box is made of 1-inch by 12-inch cedar boards, and must be painted black inside. The upper mirror rests on a cleat, and the lower mirror on the bottom of the box. Holes may be bored in the bottom of the box to permit of drainage, if desired, although we have not found this necessary, as the overhang of the roof prevents most of the rain from blowing into the box. We, of course, had to have mirrors cut to fit our box. In order to preserve the back of the mirrors from the effects of dampness, I glued asbestos on the back of the mirrors, with waterproof glue, and shellacked the edges. For a turning handle I use a shovel handle fastened to the bottom of the box by means of screws. Our periscope takes in the whole of a 360-yard hole. Greenkeepers’ Register.—The editors of The Bulletin will be glad to receive letters from greenkeepers seeking employment and forward names and addresses to clubs in need of greenkeepers. Applicants should indi­ cate their experience, age, and references.

The underground supply pipes on our course are down the center of our fairways and are provided with risers every 100 feet. Probably risers every 150 feet would be ample, since, with 80-pounds pressure and 50 feet of hose, we actually cover a circle 240 feet in diameter without disconnecting the hose, by occasionally moving the sprinkler. For the axles of the wheels we use 11/o-inch galvanized iron pipe, on cither end of which are reducers to 1 inch, which reducers hold the wheels in place. The inner wheel is off center, the cross being at the center and the whetl to the side of the cross. The material used in the construction of a single set of sprinklers is as follows: 196 BULLETIN OF GREEN SECTION OF THE Voi.iv.No.8 i ii 'ini nii! 3 old rimless automobile wheels with old casings and no inner tubes, l^-inch galvanized iron pipe; 3 pieces each long enough to serve as axles for the wheels, extending on each side of hub far enough so that l^-inch by 1-inch reducers may be firmly attached to the ends to hold the wheel in place.

Where freight rates and other items are not so high the price should be very much less. The 2 pipe wrenches, and the pliers for the guy wire, are the only tools needed in assembling the sprinkler. The first sprinkler we built had specially made iron wheels for 1-inch axles, each of which cost us $3 or $4 here; but this cost of wheels we practically eliminated by using old Ford wheels with old cas­ ings costing us next to nothing. The substitution of Ford for iron wheels is our modification of the sprinkler. When not in use, the sprinklers can be run off in the rough, and should a ball stop under one it is not difficult to pull or push the sprinkler far enough out of the way to permit the ball to be played. Likewise should a ball stop under a sprinkler in use on the fairway, the sprinkler can be moved to permit playing the ball without cutting off the water or getting wet. The advantages of this sprinkler are simplicity of design, cheapness of construction, ease of moving,- large area watered at each setting, ease of keeping in order and repair, and the fact that less frequent connections of the hose have to be made, or shutting off of the water, since with each connection of the hose the sprinkler can be moved from six to ten times, depending on the width of the fairway, before it is necessary to make another connection. This saves the time of greenkeepers and the wear on valves and hose, and permits the maximum use of water, and also enables one man to look after the watering of more fairways than does any other device within our means that has come' to our attention.

Golf Association Decisions on the Rules of Golf Question.—Four-ball match. A and B against C and D. All four balls on putting green, D’s ball being farthest from the hole. D putts, his ball striking A’s ball, knocking it into the hole. A claims to have holed on his last stroke and refuses to replace his ball, as provided in Rule 2 of Special Rules for Four-Ball Matches. Who is right ? Answer.—The rule you cite covers the point you bring up. A has no basis for his claim that he holed out on his last stroke, and under the rules must replace his ball. Question.—Is there any United States Golf Association rule against using drivers with iron heads? I have been informed that iron clubs are only permitted on tees of short holes. Please tell me whether there is any restriction on the use of iron clubs on tees of long holes. Answer.—There is no United States Golf Association rule nor any rule in any other association that restricts a player in the use of any club he sees fit to use in making any shot. One of the prerogatives of a player is that he shall have his choice of the implements with which he wishes, to play the game. Question.—In a handicap match tournament A had to concede three strokes to B. Their match was halved. Three strokes fall to be taken at the 1st, 7th, and 14th holes. A and B agreed to decide the match by playing the 19th hole on even terms. Were they within their right in making this arrangement? Answer.—Yes. In the absence of any conditions for playing halved matches (see preface to “Decisions by the Rules of Golf Committee”) the players‘are at liberty to make their own arrangements.

Clover for Southern Fairways in Winter.—We find that a number of golf courses in the South have clover on their fairways so that they may have a green turf during the winter and early spring before Bermuda starts to grow, and we are thinking of seeding our fairways with clover and Bermuda mixed. If you think this is a good idea, kindly ad­ vise us what kind of clover should be planted and when it should be seeded. (South Carolina.) Answer.—Spotted bur clover is probably the commonest clover which appears in fairways in winter in your locality, but in addition there is more or less white clover and native Carolina clover. Bur clover is best seeded in early fall or as soon as the hot weather of summer is over. If hulled seed is used, it should be sown at the rate of not less than 15 pounds of seed per acre; if seed in the bur is sown, it will require 5 or 6 bushels of seed per acre. After the seed is sown it should be lightly harrowed in. The plant is an annual, but when once established it re­ seeds itself naturally from year to year. Bur clover is greatly helped by the addition of lime to the soil, and indeed it is commonly found in soil where there is a good deal of either lime or marl. To succeed with bur clover the soil should be inoculated with the proper bacteria for this plant. This inoculation may be effected by the use of either the pure culture sold in glass containers, or the soil from a field already growing bur clover, alfalfa, sweet clover, or yellow trefoil. The soil-transfer method is more dependable than the pure-culture method. In the soil-transfer method, soil from th’e top 8 inches of a field growing bur clover, alfalfa, sweet clover, or yellow trefoil should be broadcast at the rate of 500 pounds per acre over the area to bq planted. On account of the expense involved, it is generally advised to sow but a small patch the first year, which should supply abundant soil to use as inoculation for more extensive plantings. Often when seed in the bur is sown there are enough bacteria in the dust on the burs to insure inoculation. 2. Improving the Drainage of a Green Flanked by a Hill and of a Green on a Clay Subsoil.—One of our greens is flanked by a steep ii 1. Its surface drainage is good. Two years ago in the fall it was in very poor condition. Last spring it was given the same treatment as the o ier greens with regard to weeding and top-dressing. It did not respond o this treatment, and as it became thickly infested with crab grass we decided to do nothing further with it that season but to returf it the ° .sPrin"- Late last fall we plowed it, removed the top soil, re­ modelled it, and covered it with a fairly thick dressing of well-rotted manure. The green is not at the base of the hill, there being a 5-foot errace m front of it, and the natural drainage should therefore be good; 202 BULLETIN OF GREEN SECTION OF THE voi.iv.No.8 nevertheless it certainly gets much seepage from the hill behind it. The high point of the green is directly in the back center and in a line with the crown of the hill, and there is therefore a perceptible fall both to the right and the left. In view of this we have thought that, rather than to lay a network of tile underneath the green it would suffice to lay one line of tile parallel with the back of the green, draining to both right and left. Another of our greens is built on a pure clay foundation. The sur­ face drainage can be easily corrected, although there are now some low places. The turf has showed signs of lack of proper drainage, but on account of the character of the subsoil we are afraid that subdrainage is imperative. The turf is by far the best we have on any of our greens; in fact, it is a beautiful piece of bent turf; and for that reason we hesi­ tate to disturb the surface any more than necessary. (Pennsylvania.) Answer.—AVe feel sure from what you say with regard to the hillside green that the trouble is due to poor drainage. The wettest place on a hill is often about half way down the side and not at its base. At that point water will continually seep out from the high ground in the rear; this we have noticed on many golf courses. The best remedy is to cut a grassy hollow’ back of the green, say 4 or more feet in depth, sloping the hollow so that it drains any seepage water that comes out of the hill, around the green. The same results can probably be obtained by the use of tile, if it is not desirable to construct the grassy hollow. If tile is used, we would advise sinking the tile at least 4 or 5 feet below the surface in order to be sure of catching any seepage water that is working toward the green. We see no reason why you should not take it to the right and left, as you suggest; in that case there ’would be no necessity for connect­ ing the two drains. The drainage of the other green you mention would probably be best effected by running two or three lines of 4-inch tile under the lower parts of the green. If care is used in taking up the turf, installing the drain, and relaying the turf, the green should not be out of play for any con­ siderable time. 3. How to Seed New Greens.—A difference of opinion regarding the seeding of a new green has come up in our club. Our old plan was to level the green as truly as possible, seed on the top, and rake the seed in very lightly and carefully. We only raked a very little, so as to get the surface and the seed slightly mixed, and then rolled it. A new plan has been suggested, namely, to seed and then cover with anywhere from i/.-inch to 4 inches of eartli. The old-timers’ view is that the seed 'would never grow up through this and that the seed should be as near the surface as possible. (New Brunswick.) Answer.—In seeding a new green, the point to which most attention should be given is the even distribution of the seed. We recommend that 3 pounds of good bent seed be used in seeding each 1,000 square feet of surface. This is regarded as a sufficiently heavy rate if the seed is sown properly. It is usually much easier to get an even distribution by mixing the seed with top soil, as this gives a larger bulk, which is more easily distributed evenly than a small bulk. The late Fred AV. Taylor, of Phila­ delphia. found it possible to get uniform and highly satisfactory stands of mixed bent grass on greens by mixing the seed with shredded'peat moss. He used a very small quantity, probably not more than 1 pound to 3,000 square feet. His method was, however, expensive and the advantages gained by it were not in proportion to the cost. If the seed is sown alone August 2i, 1924 UNITED STATES GOLF ASSOCIATION 203 —that is, not mixed with top soil—it is easier to get a uni­ form stand by covering the seed evenly with top soil, say ap­ proximately 1 cubic yard to 5,000 square feet; but this, of course, is expensive, and unnecessary, provided rakes are used carefully for covering. Seed may be simply raked into the soil and sufficiently covered by the use of ordinary garden rakes or by an implement known as a weeder. The point to bear in mind in this case is to avoid the dragging of the seed into rows. There is also another point to watch carefully, and that is the watering of a newly sown green. Heavy water­ ing has a tendency to wash the seed into waves and thus produce a very uneven stand. Water very slightly, simply enough to keep the surface moist, until the young plants have made a good start. 4- Grasses for Winter Greens in the South.—We expect to sow winter grass in the fall and wish you would give us an idea as to the best mixture to use. (Georgia.) Answer.—Our information indicates that best results are obtained m the South by sowing a mixture consisting of 4 pounds Kentucky blue­ grass, 1 pound reclaimed redtop, and Vt-pound white clover, particularly inasmuch as the bluegrass and white clover are immune to brown-patch. It is possible that in Georgia you will not be troubled much with brown- patch in the winter, although this disease causes considerable damage to greens in the winter’ farther south, as around New Orleans and in southern Florida. If you are not troubled with brown-patch in winter, you will obtain best results with redtop alone, and next best results with Italian rye-grass alone, although both of these grasses suffer severely from brown- patch. We do not think it well to mix these two grasses, as they make somewhat different putting conditions, the rye-grass being a coarser grass than, the redtop. Do not use fescue, as it will not do well under vour conditions. White clover will grow nicely in vour location in the winter. You may, however, not desire it from a putting standpoint. All of these grasses should disappear early in the summer, giving place to your Ber­ muda grass for your summer greens. In order that these winter grasses ,n?y have a fair start they should be seeded, in your latitude, about the middle of September. So that you may know definitely which grass is best for winter greens under your conditions it would be advisable for you to experiment with the different seedings, sowing a few of vour greens to the Kentucky bluegrass and white clover mixture, a few to redtop, and a few to Italian rye-grass. a Eradicating Poison Ivy and Poison Sumac.—Please let us know nm to exterminate poison ivy and poison sumac from our golf course We are bothered very much with these pests around the fence lines and m the brush section of some of the small gullies (Illinois ) most, ril|,i,] and effective way to deal with small iso­ lated clumps of these plants is simply to pull or grub them out, taking rare to remove thoroughly the running underground parts, since pieces of the plants left in the ground will soon produce another crop of plants rhe plants are also killed by frequent mowing carried out persistently so as to prevent the roots from developing green growth above ground. Small patches may also be killed by covering them with tarred or other heavy paper to the complete exclusion of light. The edges of the paper should be either pegged or well weighted down. Another good method, especi­ ally for killing vines of poison ivy on fence posts and on trees, is to cut the poison ivy below the ground and then saturate the soil around the cut bases of the plants with salt brine. A second dose of brine should be 204 BULLETIN OF GREEN SECTION OF THE Vol. iv. No. 8 applied about two weeks later if the roots show signs of putting forth new growth. Thorough wetting with kerosene oil, applied with a spray­ ing pump or sprinkler, will kill the plants after one or two applications. The effectiveness of the treatment will be increased if the soil is disked or cut up slightly, so as to expose the roots to the action of the kerosene. As kerosene will injure or destroy all vegetation, it is, how’ever, not safe to use around valuable trees and shrubs. One of the most useful methods of killing the leaves of these plants (and if the leaves are killed and not allowed to develop, the entire plant will die) is to spray them with a saturated salt solution prepared at the rate of 3y2 pounds of common salt per gallon of water. For this purpose the spray should be applied as a fine, driving mist, which may be done by use of an air-pressure sprayer. Small, inexpensive hand sprayers suitable for this work are now on the marktt. As soon as a new crop of leaves appears the plants should be sprayed again. If this spraying method is persisted in, the plants will gradually disappear. Crude sulfuric acid also may be used, applying a few drops of the chemical to the bases of the plants at intervals of a week until they die. This may be done conveniently by means of a copper spring-bottom oil can, such as machinists use. Care must be taken to avoid spilling the chemical on the hands or clothing, as it is a dangerous caustic. In undertaking this work of eradication, the wearing of overalls and heavy gauntleted gloves is recommended. In case of contact with poison ivy or poison sumac, infection may be avoided by the use of a grain-alcohol wash to which lead acetate, a chemical obtainable at any drug store, is added, followed with a brisk treatment with strong soap and water. If these chemicals are not available, however, the affected skin should be washed thoroughly and as soon as possible with a heavy lather, preferably in running water. Hard scrubbing of the skin with a stiff brush should be avoided. 6. Fertilizing to Improve Fairways.—The base soil of our fairways is heavy clay and in our opinion inclined to sourness. The top soil is very thin and rests on top of the clay in an entirely separate stratum. Much of the fairway is covered by moss, in which there is some grass growing and a considerable amount of clover. Two years ago plant lime was liber­ ally used for the purpose of sweetening, but there is considerable doubt as to whether any benefit was derived from this. We have had no practical experience in the use of ammonium sulfate, but our professional raises the point that this chemical will so kill or drive out the clover and moss that any benefit to the grass would not bring the surface to as satisfactory a playing condition as now exists. It may occur to you that our difficulties are a result of a basic condition which should be remedied by the use of sand or other substance to break the clay, and which would involve con­ siderable expense. Because we are using leased land under such condi­ tions as to make our centinued use of the property uncertain, the club does not feel justified in undertaking expensive improvements. The policy of our green committee is to secure the best practical results from the course as it. stands. In your opinion, from the facts given you, should ammonium sulfate be used, and, if so, should the mixture be heavier or lighter than that recommended by the Green Section? (Ohio.) Answer.—We judge from your letter that the soil of your fairways is poor and also that there is a considerable amount of moss on it at the present time. As for using sulfate of ammonia under such conditions, we have not the slightest doubt but that an application of it at this time of the year (August 20) or a little later would be helpful for fall growth; August 21,1924 UNITED STATES GOLF ASSOCIATION 205 Ammonium sulfate is an excellent quick-acting fertilizer, but unless it is applied carefully during the hot summer months it is likely to scorch the grass. In the summer 1 pound to iy2 pounds ammonium sulfate to 1,000 square feet can be used with reasonable safety. In the fall or spring double this quantity is recommended. As for doing away with moss and white clover, there is some evidence that ammonium sulfate will so pro­ mote the growth of grass as practically to dispose of moss, but it is only after repeated applications that it has this effect on white clover. With­ out knowing more specifically of your conditions, we would advise an ap­ plication of ammonium sulfate at this time of the year (August 20) or possibly as late as September 15, and an application of bone meal at ’the rate of approximately 500 pounds per acre in the early spring, about the first of March. Since you do not own the land you occupy and do not wish to go to much expense in the matter of permanent improvement, top­ dressing with compost would appear to be out of the question. However, if you can get well-rotted manure for top-dressing this winter, we think it might be a profitable investment. The bone meal will go far toward improving your turf, however, and with a little ammonium sulfate this fall and a liberal application of bone meal next spring you should have reasonably good turf for next season. 7. Controlling White Clover and Chickweed with Ammonium Sulfate.—This season our greens are badly infested with chickweed and white clover. We have been using ammonium sulfate on the greens at intervals of three weeks. We use 3y2 pounds for a 4,000-foot green. Is this strong enough to discourage the clover and chickweed? Last year we used it stronger but it burnt the grass a little, which, however, soon recovered. It also burnt the clover and chickweed. (Pennsylvania.) Answer.—We regard the rate you have used, 3y2 pounds for 4,000 square feet, as a very light application. Our method of applying am­ monium sulfate is to mix it with well-screened compost composed of° loam or clay loam, well-rotted manure, and sand at the rate of approximately 12 to 15 pounds of ammonium sulfate to a cubic yard of compost. This cubic yard of compost is sufficient for top-dressing 5,000 square feet of green. In other words, by this method we apply approximately 2y> to 3 pounds of ammonium sulfate to each 1,000 square feet of surface Where we can do so, we make applications of ammonium sulfate mixed with com­ post every month during the growing season. By applying ammonium sulfate mixed with compost and watering the greens thoroughly after the application is made, we have had practically no trouble from burnin- During the hot weather we use only approximately 1U pounds of am­ monium sulfate to each 1,000 square feet. We realize that ammonium sulfate will burn grass especially in the summer, if exceedingly great care is not taken. V e believe that the continued use of ammonium sul­ fate in the manner here suggested will go far toward discouraging clover and chickweed, although this method is at times very slow in brin
