Published by Turfgrass Connections, Sisters, Oregon Printed by X-Press Printing, Sisters, Oregon Editorial Comment Summer is upon us and fall will arrive before you know it. The Northwest Turfgrass Association is celebrating the beginning of it's "Second 50 Years". To commemorate this "beginning", your Board of Directors has approved some new amenities for the up-coming Conference at Sunriver Resort, October 12-15, 1997. First, please note on page 19 that the conference attendee may or may not currently be a member. The price is the same. Also, the registration fee includes the "Get Acquainted Reception" on Monday night, a Continental Breakfast and coffee break on Tuesday and Wednesday mornings, lunch at the Annual Meeting on Tuesday, and the Banquet with Dr. Larry Helms returning as our banquet speaker. This year's Conference has been pared down from three and a half days to two and a half days, including the Roy L. Goss Golf Tournament. Now you will have time to play another Sunriver golf course (the Dr. John Wagner, President, Washington State Golf Association. Meadows or Woodlands course) on Wednesday afternoon! Throughout this issue of Turfgrass Topics, check out the brief descriptions of the events: Roy L. Goss Golf Tournament at Crosswater, the Turf Tour, the Companion Program and the Conference Program. Registration this year has the option of "Invoice Me" or "Payment Enclosed" and the registration itself may be mailed or faxed to my office. Either way, faxed or mailed, you will be obligated to follow the "Refund Policy" as stated on the registration form. Your Board is already working on 1998's Conference at Coeur d'Alene Resort. On July 21, 1997, the Third Annual Columbia Cup Tournament was played once again at Indian Summer Golf & Country Club in Olympia, Washington. Vice President and host, Tom McCarthy and the gracious members at Indian Summer treated us to a grand day on the links. During the winners presentation ceremony, Washington State Golf Association, represented by Dr. John Wagner, Jack Challender, Bill Mays and John Bodenhamer, made a check presentation to Northwest Turfgrass Association for $43,000 to support research in the Pacific Northwest. "The first such cooperative research funding between a state golf association and a turfgrass association in the United States," said Larry Gilhuly of the USGA to the assembled crowd. Larry also told the group that this "industry support" played a critcal part in Washington State University's decision to replace the research position vacated by our retiring Lifetime Honorary Member, Dr. Stan Brauen, from the Puyallup Experiment Station.

As a golf coach, golf show promoter, Board of Directors of a private club, and fellow golfer it was wonderful to participate in such a worthwhile event. My compliments to Don Clemans, Greg Crawford, and especially Tom McCarthy, and the entire staff at Indian Summer Golf and Country Club. It is my hope that the golfers in Oregon can someday match the $43,000 that was presented to you from Washington golfers, and I hope my small donation of $100 will show you that you are doing a great job - keep up the good work. Sincerely, John D. Hinds From Dr. Doug Hawes - TurfComms Root Zone Mixes, A User's Comments by Gary Grigg: " I thought your last issue of TurfComms was very informative. I have several opinions on several of the subjects and will lend them to you for whatever my experience is worth." ( Ed. Comment, if Gary's comments aren't worth reading whose are?) " On the subject of California root Zones: over the last 3 years we have reconstructed 41 greens here at Royal Pointciana Golf Club. The first were total USGA with choker layer. The next 19 were USGA without choker layer. The short course practice area greens (3) were built with, I guess what I would call modified California style. We cored out these greens 12' deep and doubled the typical amount of drain tile. We used .25" gravel around the drain tile to the level of the subgrade. We used a USGA size sand mix - 85% sand with 15% peat moss. Laid the root zone mix directly on the subgrade and drain tile. After three years, these greens have a much better developed root system. The greens without the choker layer are not as good but closer than those with the choker layer. The full USGA greens have at best 1/3 the root system of the "California" greens. The California greens never have an algae problem - which is one of our largest problems. They do tend to stay drier but we have double heads around the greens and can water greens separate from the surrounding area. I think this is a key to making them work. What will I think after 10 years?? who knows. Right now I would have to be talked out of doing them any other way in South Florida. Cost savings is around $100,000 per 18 hole course." THE TEN COMMANDMENTS OF COURSE REMODELING By Bo Links, Keynote Speaker at the NTA's 51st Conference in Sunriver 1 2 3 4 5 Thou Shalt Seek Out Objective Analysis If you really want to know where you stand regarding the condition of your golf course, bring in an objective, outside evaluator, such as the USGA Turfgrass Advisory Service (TAS) for a full day's visit. Consultation with knowledgeable, objective experts will save months of research and avoid guesswork. Arm yourself with the facts before proceeding further. The key issue is: Do you need to do anything, and if so, what? Thou Shalt Educate Committees Make sure the Green Committee participates in all meetings with outside professionals, including all TAS visits. They can't do their job without knowing the status of the golf course and how to address diagnosed problems. Thou Shalt Educate the Golfers Course remodeling can be an emotional issue, and it may take time to make the golfers fully aware of problems that have been diagnosed. Go slowly, pay attention to everyone's varied concerns, and be sensitive to the fact that many golfers may not at first appreciate the seriousness of the problem. Give them time. Proceed golfer by golfer, talking to people on an individual or small group basis. Thou Shalt Develop a Plan and Stick To It If the data support some form of remodeling or renovation, don't ignore the problem and, equally important, don't rush to cry out, "Let's remodel!" Decide what is needed, develop a realistic plan to accomplish specific goals, and make every attempt to finance the work without having the price become the main issue. Before submitting a plan, know the scope of the work, the true cost, and a realistic schedule. Thou Shalt Understand the Economies of Scale Keep in mind that it may be most efficient to do all the needed work at one time, rather than spreading it out over several years. A course can achieve substantial savings by having one crew and a single deployment of equipment. There also can be sizeable savings through bulk buying when it comes to purchasing the various supplies needed to do the job. If there are related tasks the golf course is contemplating (improvements to the sprinkler system, new irrigation pipes, etc.), consider doing the work at the same time as the remodeling job so as to minimize the inconvenience to the golfers. The only thing worse than having your golf course torn up is having it torn up more than once. 8 ^luM^MilU 6 Thou Shalt Select a Cohesive Project Team to Do the Work and a Small Committee to Oversee It Make every effort to have a cohesive team in place. If the architect you select has a preferred contractor, give that recommendation serious consideration. Price may be a factor here, but consider that having a team working together - rather than one beset with internal friction - will likely save money in the long run and, more important, produce a superior end product. In addition, have a small committee oversee the project. No orchestra ever played a symphony with multiple conductors twirling the baton at the same time, and no remodeling job ever succeeded with an army of armchair architects "supervising" the real architect. Use the committee as the interface between the architect, contractor, and the golfers. While opinions from knowledgeable golfers about playing conditions and potential changes in course design can be helpful, they should be filtered through the committee, rather than having the architect and contractor besieged by golfers' input during the job. 7 Thou Shalt Respect Mother Nature Realize that seasons change and so does the weather. Winter is not a good time for heavy construction work (rain is a four-letter word to golf course contractors). Anyone reseeding needs to give the grass enough time to grow in before the rainy season arrives. While no one can predict the weather, careful planning can allow the work to be done during the spring, summer, or fall - during a dry period and a good growing season - when earth moving can be done easily and efficiently, and the grass can be in place before trouble (in the form of rain) arrives. While this may entail cutting into the course's busy season and the remodeling work may result in some loss of revenue, in the long run it will be an advantage to have new fairways, bunkers, and greens in place with the grass rooted before the rains come. 8 Thou Shalt Be Reasonable With Respect to the Difficulties of the Job Understand that there will be unforeseeable events. The contractor may encounter bad weather, unmarked utility lines, and so forth. Make every effort to anticipate these items and arrange for underground services to be marked ahead of time, but keep in mind that the unexpected can and will occur. No job is perfect, but the more reasonable people are about seeing the task through to completion, the better off everyone will be. (Continued on page 9) 9 Thou Shalt Keep Thy Golfers Informed At most courses, even the naysayers eventually come to support the project. The key to producing a turnaround is informing everyone, including the doubters, and keeping them informed as the job moves forward. Take golfers on tours of the course and show them the work in progress, explaining how the greens are being built and how the new drainage system beneath the greens and bunkers is being installed. They can see for themselves how substantial the improvements are and how efficiently the contractor is proceeding to complete the job. One tip worthy of note: If possible, have the contractor complete areas visible from the dining room first, so visitors can see the progress, rather than be constantly exposed to plowed dirt. And note: Make sure your golfers know what to expect once the job is done; perhaps the greens will be slow at first, and maybe there will be some plugged lies in bunkers. For an excellent reference, see "Avoiding the Hazards of Golf Course Renovation," Green Section Record, July/August 1995. 10 Thou Shalt Make Arrangements for Golf Play During Construction One of the biggest problems is making sure golfers can play golf while the remodeling work is ongoing. This can be done by making arrangements with neighboring courses or by constructing firstclass temporary tees and greens within the existing golf course. Note: The issue of providing access to golfing facilities is especially important for older golfers, who may feel their course is being taken from them during their last years of being physically able to play. Aside from helping them understand that their present-day sacrifice will provide for their grandchildren, it helps to accommodate their needs so they not only can watch the future being built, but play their way into it at the same time.

P.J. Landschoot and A.S. McNitt, Pennsylvania State University, Department of Agronomy Over the past few years there has been a lot of interest some may say hype —in using natural organic fertilizers (fertilizers derived from plant and/or animal by-products) and composts for turf disease suppression. The theory behind this is that natural organic products contain microorganisms and/or enhance the build-up of indigenous soil/ turf-inhabiting microorganisms which inhibit certain turf diseases. While there is not enough research-based information to substantiate these claims for most turf diseases, the use of natural organic products for dollar spot suppression has been studied extensively and appears promising. Studies at Cornell University by Nelson and Craft (1992) found that some natural organic fertilizers and composts were highly suppressive to dollar spot when applied preventative^ as topdressings on putting greens. The authors suggested that dollar spot suppression following applications of some of the treatments likely resulted from microbial suppression. Although these results are encouraging, the authors did not compare the treatments used in the test with synthetic organic or inorganic (non-organic) nitrogen (N)containing fertilizers to see if the disease suppressive effects were related to N nutrition. In a different study in Canada, Liu et al. (1995) looked at the effects of several N-containing fertilizers, including ammonium nitrate (an inorganic fertilizer), Sustane and two Ringer products (natural organic fertilizers), on dollar spot suppression and microbial populations in turf foliage, thatch, and soil. Treatments providing the greatest disease suppression-ammonium nitrate and two natural organic fertilizers (Ringer Turf Restore and Ringer Greens Super) - yielded higher microbial populations in turf and soil than other treatments. The authors concluded these fertilizers play a role in boosting microbial populations and can suppress dollar spot, but that the actual means of suppression is not well understood. It could be that N nutrition, as well as microbial suppression, played a role in reducing dollar spot in this study. At Penn State, we conducted a three year test on dollar spot suppression on bentgrass putting greens using four natural organic fertilizers and two synthetic organic fertilizers. Our objective was to determine if suppressive properties are more pronounced with the fertilizers derived from natural organic sources than with the synthetic organic fertilizers when applied at similar timings and rates of N. Below is a summary of how we conducted the test and our results. Description of fertilizers used. Six fertilizer products were used in this test. Four of the fertilizers are derived mainly from natural organic sources and two are synthetic organic sources. They are described as follows: Natural Organic Sources: Ringer Commercial Greens Super (10-2-6) is a formulation of feather meal, blood meal, wheat germ, bone meal, liquid fat, D-limonene, and potassium sulfate. Ringer Compost Plus (7-4-0) is composed of wheat midds, calcium carbonate, dried molasses, bone meal, urea, and liquid fat. This product also contains two species of bacteria, Bacillus subtilis and Bacillus licheniformis. Sustane (5-2-4) consists of composted turkey litter. Product literature states that Sustane contains over 1.5 million bacteria per gram of dry weight of product. Individual species are not listed. Milorganite (6-2-0) is an activated sewage sludge produced aerobically digesting screened waste water followed by settling the biomass into thick fibrous cakes. The biosolid cakes are subjected to temperatures between 454 and 648°C and then are dispersed into granules. Synthetic Organic Sources: Nitroform (38-0-0) is a trade name for ureaform, the product of a chemical reaction involving urea and formaldehyde. Approximately one-third of the N in Nitroform is quickly available, whereas the other two thirds are slowly available. Urea (46-0-0) is a quick release fertilizer produced by reacting ammonia gas with carbon dioxide in the presence of a catalyst. Description of experiment. This study was conducted at Penn State from 1992 to 1994 on "Penncross" creeping bentgrass maintained under typical golf course putting green management conditions. All fertilizers, except Nitroform and one urea treatment, were applied four times per year at 28 to 33 day intervals at two rates, low rate of 0.5 lb. N 1000 ft2 and a high rate of 1.0 lb. N/1000 ft2 Nitroform was applied twice each year at 56 to 66 day intervals a rate of 2.0 lb. N/1000 ft2 per application. One of the urea treatments was applied at 0.5 lb. N 1000 ft2 every 14 to 16 days (eight applications per season). The total amount of N applied during each season was 4.0 lb. N 1000 ft2 for the high rate treatments and 2.0 lb. N 1000 ft2 for the low rate treatments. A fungicide treatment was included in this study for com(Continued on page 12) ii parison with the fertilizer treatments. Daconil was applied every 14 -days (eight applications per season) during 1992, 1993, and 1994. Control plots did not receive any N during 1992, but in the spring 1993 and 1994, control plots received 0.5 lb. N 1000 ft2 of urea prevent thinning of turf. Plots were rated for dollar spot severity on a scale of 1 to 10, with 1 = no disease and 10 = 100% of the plot area affected. In 1992, dollar spot was rated when differences among treatments became apparent. In 1993 and 1994, disease was rated every week, beginning when symptoms were visible until September when plots were sprayed with Daconil to control the disease and hasten recovery the turf. Color ratings and foliar N analysis served as indicators of turfgrass response to N. Turf color was determined by visual observation on a scale of 1 to 5, using half units, with 5 representing the darkest green color obtainable and 1 representing a bronze color. Results of the test. Differences in dollar spot disease, when expressed as a cumulative rating over the entire season, were found among the fertilizer treatments included in this study. (Table 1). Results for the 1992 season showed that none of the fertilizer treatments provided 71% 01 is disease suppression when compared with untreated control. In 1993, the high rates of Ringer Compost P and urea (28-33 day intervals) were the only treatments that provided lower disease ratings than the untreated control. During the 1994 season, all fertilizer treatments gave greater suppression dollar spot than the untreated control. Also in 1994, all of the high rate fertilizer treatments, except urea, provided superior disease suppression compared to low rate treatments of the same products. Whereas none of the fertilizers suppressed dollar spot to a greater degree than the fungicide treatment at any time during the study, the high rate of urea (28-33 day interval), the 0.5 lb. N 1000 ft2 (14 day interval) urea treatment, the high rate of Ringer Compost Plus, and the high rate of Ringer Commercial Greens Super gave better disease control than other fertilizer treatments in at least one year of the test. (Table 1). Results showed that on the majority of rating dates there was a good relationship between turf color and disease (Table 2). In general, as color became darker the disease incidence decreased, indicating that as more N becomes available to the plant, dollar spot is not as severe. This relationship became more pronounced in September, when disease severity tended to peak. earth's surface bywater... (Continued on page 13) F e a t u r i n g . . .

Nitroform produced a dark green turf for much of 1992 and 1993, but did not provide disease suppression comparable to urea and the Ringer products. The lack of dollar spot suppression with ureaform fertilizers has been observed in previous studies (Cook et al., 1964 and Markland, et al., 1969). Assuming that a dark green color is an indication of increased foliar N concentrations, our findings suggest that N availability is strongly associated with disease suppression. To confirm this assumption, correlation analysis was performed on turf color ratings and foliar N concentrations (expressed as % foliar N) for all fertilizer treatments and the untreated control on two rating dates (2 September, 1993 and 9 September, 1994). Results showed that turf color was significantly correlated with % foliar N (data not shown). Conclusions. This study demonstrated that urea, a synthetic organic N fertilizer, provides equal or better control of dollar spot disease than fertilizers consisting primarily of natural organic by-products. These results are similar to those obtained by Liu et al. (1995) in which ammonium nitrate showed equal or better control of dollar spot than the natural organic fertilizers Ringer Greens Super, Milorganite, and Ringer Lawn Restore. Results from our study showed that, in most cases, disease suppression was associated with dark green turf, presumably a response of the turf to N. This finding indicates that the suppressive effects of urea and some natural organic fertilizers may be due, at least in part, to N availability. There is ample evidence to show that N plays an important role in plant disease resistance. Nitrogen is essential for the production of many compounds involved in resistance, including phenolics, phytoalexins, growth hormones, cellulose, and carbohydrates (Huber, 1980). Nitrogen may also help turf to escape severe dollar spot damage by allowing plants to "outgrow" the pathogen and by promoting quicker recovery from disease injury (Liu et al,. 1995 and Monteith and Dahl, 1932). Currently, there is little information concerning the relative contributions of N availability and microbial suppression resulting from fertilizer applications to the reduction of dollar spot severity. Few studies have been designed to take into account the effects of N use by the plant and microbial suppression both together and independent of one another. Nelson and Craft (1992) assumed that dollar spot suppression obtained from some com- posts in their study was due primarily to microbial effects, but did not monitor plant responses to N. Liu et al. (1995) reported that the higher microbial populations found associated with certain fertilizer treatments may have been related to disease suppression, but acknowledged that increased turf growth due to increased N levels could affect expression of dollar spot symptoms by allowing the grass to outgrow or recover from infections. Other studies, including ours, have concentrated on the turf response to N, but not on microbial suppression. The low amount of disease suppression with Nitroform in our study may indicate that N assimilation is not the only factor responsibility for a reduction in dollar spot severity. Although there is evidence that dollar spot can be suppressed by certain microorganisms (Nelson and Craft, 1991), disease reduction by means of increased resistance resulting from applications of inorganic, synthetic organic, or natural organic N-containing fertilizers and composts is potentially important and should not be overlooked in dollar spot control programs.

Take time to talk with them about your safe and responsible use of pesticides. Studies show that most people don't know that pesticide products are among the most highly tested products sold. The U.S. Environmental Protection Agency (EPA) registers only those uses of pesticide products that pose minimal risks. • Emphasize that pesticide products must undergo stringent government-monitored testing before they can be sold. It is a long and costly process. For example: - It takes a chemical manufacturer eight to 10 years to test and register a product, at an average cost of $30 million to $50 million. - As many as 120 tests or more are performed, many specific to health, safety and the environment. - Only one potential pesticide in 20,000 makes it from the research lab to the market. • Explain Integrated Pest Management (IPM) to your customers. Most do not fully understand the concept. Point out that a successful 1PM program stresses prevention, pest identification and selection of the best method of pest control, which may require the use of pesticides.

No one has taken this more to heart than Audubon International, the Golf Course Superintendents Association of America (GCSAA) and Rain Bird. Based in Selkirk, N.Y., Audubon International launched its Cooperative Sanctuary System to work with private landowners in implementing environmentally sound practices to preserve and enhance natural resources. Audubon International developed such programs for businesses, homes, schools and golf courses. "Though many people believe that state or federal government agencies and their staffs have sole responsibility for wildlife and habitat protection, it is clear that the majority of real property is owned by private individuals and organizations", says Audubon International President and CEO, Ron Dodson. "Most state agencies do not have the resources to manage private lands. This is why AI launched the Audubon Cooperative Sanctuary System." The golf course superintendent profession has been a leading participant in the Cooperative Sanctuary System through Audubon International's school and golf course programs. As a national sponsor for the Audubon Cooperative Sanctuary Program for Schools, GCSAA has partnered with Rain Bird to provide funding and services to promote awareness and participation in the program. The school program is a hands-on approach for community leaders, such as the golf course superintendent, to work with students, faculty, parents and the community to promote environmental stewardship. By creating a sanctuary on school grounds, students, faculty and parents are able to learn firsthand the tech- COME JOIN US IN SUNRIVER!!!

To become certified in the program, schools must meet established requirements in environmental education, wildlife habitat management, waste management and resource conservation. People from the community, such as golf course superintendents, provide resources, expertise and supervision to transform school facilities into a certified sanctuary. Projects include recycling, bird nest boxes, butterfly gardens and nature trails, among others. Along with the Audubon Cooperative Sanctuary Program for golf courses, sponsored by the United States Golf Association, the school program was born in 1991 to protect and enhance the quality of the environment on the school grounds.

Rootzone Construction and Drainage Principles By Steve Baker We were pleased that Dr Steve Baker was able to join us for the 1997 Ontario Turf Grass Symposium. He is an Associate with the Sports Turf Research Institute in Bingley of Yorkshire, England. The Institute started in 1929 and is situated on a 5-hectare site. A staff of 50 conducts research on a whole range of sports. They receive 1000 mm of rain per year Lowest winter temperature would be just above or below 0°C. The following article contains excerpts from his talk on turf rootzone construction and drainage principles for sand playing fields. O n soccer fields, wear is concentrated in the goal mouths and in the centre area. Play with rugger, soccer and field hockey is from early May to August, and very little grass growth occurs between September and April. Shade problems exist in many stadia due to low sun angles; thus, some stadia can receive almost no sun for a three month period. Wear is contributed by players and by maintenance machinery. Under these conditions, a well structured soil is required with sufficient pore space and air. With heavy compaction, the pore space becomes much smaller. Uncompacted soil is composed of 25% air, 25% water, and 50% solids. In contrast, compacted soil contains 25% water, 5% air, and 65% solids. In a compacted state, soil becomes anaerobic, and root penetration suffers. Root zone material is sand-dominated. Larger pores are lost, the soil drains poorly, and the soil becomes waterlogged. Why? Because the compacted top layer of 2.5 cm in depth does not allow rainfall to disperse. Another characteristic common to natural soil fields is a significant decrease in ball bounce with longer playing seasons. All of the above result in player dissatisfaction, poor playing conditions and cancellation of games. Not surprisingly, many more sand fields are coming into play. They require less laborious mixing of sand and soil, and result in better drainage and consequently, better plant growth. Advantages to the sand root zone are superior drainage, airfilled pore spaces, increased root development and consistencies of playing conditions. The major disadvantage is that natural soil fields are prone to the vagaries of weather. Potential problems with sand that Baker noted were drought, lack of balanced nutrition, and decreased stability-particularly if grass cover is lost. 22 ^MJ^MMk Tips for constructing sand playing fields • Sand topdressing - use sand that has been carefully selected for size and uniformity of grains - this allows for a high rate of drainage and adequate aeration for plant and / or root growth slit drainage - get the water off the surface by way of slit drainage - this is usually negated if no sanddressing has been applied to the surface Specifics • Pipe drainage - install 5-15 m apart, 60 cm in depth, backfill gravel close to surface, then add 15-20 cm sand • Slit drainage (50 mm diameter) - sand at surface, gravel underneath, heavy sand topdressing (150 tons), trenching 30 cm deep, remove the material taking caution not to cap slits Research Abroad In England, they use a mixture of three different ryegrasses, and an angular type of gravel rather than rounded (not limestone). In 30 soccer fields that have been built, an underheating system was installed consisting of pipes filled with water connected to a heating system, and seeding was used instead of sod. The Research Institute has tried several plastic support systems which help to reinforce the surface when grass cover is lost. Their mesh element trial is the first ever. Care must be exercised as cleats get locked in the material. Desso System from Holland, a polypropylene, is recommended. With slit drainage and heavy application of sand, fields were usually still in good condition after three months (using once a week aeration). 225 kg/ha of nitrogen per year was proposed for sand-dominated root zonesapplications much above this figure are considered wasteful and promote excessive top growth and very little root growth.

THE GOLF KING SPRINKLERS Standard Golf Course Equipment Very little can be done with water supplies containing lime, so far as removal of the objectionable lime carbonate is concerned. No more water should be used than is absolutely required by the turf. Larger amounts simply increases the quantity of lime carbonate in the soil, and makes the development of acidity more difficult.

Greenkeeper, official publication of the G C S A A , t h e n k n o w n IVh en the Dub Golfer Asks Questions By ROBERT E . POWER, Chairman Cleveland District Green Section W H A T greenkeeper has not been cross-examined by the dub golfer? betide the member who dares to criticize the golf course in any particular. Why is the rough so long? Can't you run your wagons around the course without making ruts? Haven't you any drains in your traps? What is the use of having long grass around the greens ? Why do you topdress the greens about every week ? Why doesn't your tractor stop when I'm making a shot? Those boys who foot the bills take their golf seriously. If they make the hole in seven they may win a quarte:, and if they don't it may be the greenkeeper's fault. Fred has learned to be patient with them and courteous at all times and I bring this example to the attention of other greenkeepers who may be sensitive and brood over criticisms and suggestions on the course. Patience with these new golfers who take up the game in middle life is a virtue that will earn the diplomatic greenkeeper a halo in the hereafter. It's like having three h u n d r e d employees a n d trying to please them all—even when orders are contradictory. Not being a greenXHf /I « keeper I can speak f r o m the player's standpoint. H a v i n g been a Green committee chairman off and on for fifteen years I appreciate the position of the greenkeeper, and the extraordinary tact and diplomacy he must exercise in keeping his golfing family happy. We have a foursome playing at the West wood Country Club where Fred Burkhardt is greenkeeper and where I was Green committee chairman for seven years. They play every day—their average game is around one hundred, and if Fred was an athlete training for the Olympic games he couldn't have more intensive coaching than this quartet gives him. Yet in club meetings and locker room discussions they fight for him, and woe ii The policy to pursue is one of frankness and honesty. If the greenkeeper is at fault he should admit it and correct his mistake or oversight at the first opportunity. If the player is at fault he should be told why as courteously as possible, and if he declines to see it, he should be referred to the chairman of the Green committee for further explanation. My greenkeeper always reported to me any discussions of importance with members, and if at all serio u s I straightened them out in a way to please and satisfy the member. I felt I owed it to the greenkeeper to stand between him and unjust criticism, but I would not permit him to have any altercation on t h e course. The chairman should fight all battles and it is his job to keep harmony among the members and to insist upon the greenkeeping crew being allowed to do their prescribed work without interference. I cannot close without mentioning John Morley, your president, and to comment on the real affection and regard in which he is held by the members of the Youngstown Country Club. Every member is his friend and his modest conscientious manner and unfailing courtesy has won a place in their hearts that nothing can duplicate. Which brings me to the point—a greenkeeper's value to his club is not only his knowledge of greenkeeping but his ability to co-operate with the officers in making the club a smooth running, efficient organization.
