%of capacity or fraction thereof is indicated on the schedule. The gallonage of water is thirty gallons per minute per ton of water, which added to the ten gallons per minute per ton of cooling capa­city amounts to forty gallons per minute per ton of cooling. On a monthly basis, 96OO gallons per ton at the rate of 10 cents per thousand gallons would be 96 cents. Comparison was again made on the basis of a family of four which pays at the rate of $2.75 per month for domestic water and the operation of a five-ton cooling system using 12,000 gallons per month at 25 cents per ton of capacity, which would be $1.75 for the 12,000 gallons. In other words, 12,000 gallons of cooling water would cost $1.7§ and 60,000 gallons of domestic water would cost $2.75. Mr. Stava testified as regards the El Portal Theatre that he was familiar with the testimony, that is, figures Indicated that Mr. Cragin at the El Portal Theatre "would use 1000 gallons per hour and that his receptacle did not hold anywhere near that, and it was filled up with water buckets being carried up to the unit." He fur­ther testified that "he (Cragin) probably had some water in there, and he was able to keep it replenished. In other words, if he had ample water available, he would have used more water." and "what he did no doubt was keep a simple evaporation, but the big use of water is to avoid mineralization, is to bleed these tanks heavily. In other words, to avoid mineralizing the coils, and in the air equip­ment . So in this case he was no doubt keeping up with the bare evaporation,M It is apparent that there is some discrepancy between the so-called theoretical figures of the use of water with the actual - 10 -
