22k see what the demand is and in many cases captialize on it. Records of the number and size of suits rented will be a guide in the futare purchase of suits for rental purposes and thereby eliminate the future investment in suits that are sizes ~hich are not in demand and use up veluable space that the suits of proper sizes should be using to ad- vantage. Suit manufacturers all have made up for the purchasers convenience, various proportions of sizes that should be purchased, these being baded on the salesman's experience over the country and also from the records of pool operators, however, location of the pool, charges, and many other elements will vary this figure considerably. The question of laundry is also another element in considering the purchasing of suits. Records of TOVEL RENTALS AND LAUNDRY COSTS should indicate to the operator whether it would be more economical to rent tovels rather than purchase them or whether it vould be more adventageous to install a laundry equipment and leundry the towels and suits at the pool. This if of course, out of the question to most of us operators. Records of the great- est number of tovels and suits used over a one, two end three consecutive day period, denending on the laundry conditions, will indicate the actual require- ment of your pool, Records of the sale of bathing cans, and other items, might indicate a possible savings in the future an quantity purchases without over loading. Spectators! admission will indicate vhat attractions are success— ful and bring in the spectators and those that fail to please. Of course the estimate size of the crovd ~ill tell this but records of the admissions are proof positives, Next to the record of incomes are the records of EYPENDITURES., These should be kept in detail and at the end of the season or sooner should be broken dom into such items as: Wages, which can again be broken dorn into Menager, Operator, Attendents, Life Cuards, extra helv, watchmen, etc. Cost of the various supplies could be divided into the cost and amount of vater, chemicals, electricity,ne~ equipment, suits, tovels, also pool supplies, bath house supplies, repairs, paints, advertising, insurance and others, depending on local conditions. These records ana yzed and compared vith other seasons ‘ill give the operator of the pool something to think about, Records of chemicals and bacterial tests are very important. The records of bacterial tests of the pool water made by an outside recognized agency, either public or private, will stand as evidence in Court. Records of chemical tests will also generally indicate what can be expected in bacterial tests. These chemical tests will give the operator a cross section of the condition of his water, He can correct any deficiency or eliminate any overdose by these tests. The record of chlorine, P.H. and copper sulphate tests should be a definite barometer to the operator. Records of the quantity of chemicals, either chlorine, ammonia, alum, soda-ash, lime, copper sulphate or the combina- tion of some, used to produce definite results are invaluable to the pool opera~ tor. Some of these can be kept in the head but it is well to have it as a record as memory sometimes fails. Records of all ACCIDENTS, either trivial or serious, are required. by the Insurance Company covering pool liability. Pools carrying insurance can readily see the value of these records as they are often subpoened several years after the accident occurs. These records are much more convincing to a jury than some one attempting to remember just what happened at a particular time. Records of weather, temperature, precipitation, will explain in detail some losses and gains. Of course, it is agreed that nothing can be done about the weather but the records will indicate that the management is not always necessarily at fault.
