time; It is then an easy matter to calculate 

 how many gallons the stream can supply per 

 minute. 



A ram capable of supplying 1500 gallons 

 of water in twenty-four hours to a tank fifty 

 feet above the ram, where the fall is six feet 

 and the power supply twenty gallons per min- 

 ute, should cost fifty dollars, exclusive of pipe 

 and work. The water could be stored either 

 In a reservoir of ample dimensions, built of 

 cement, and on a hill, or in a steel or concrete 

 tower tank. In either case the bottom of the 

 reservoir should be on a level with the top of 

 the highest building, in order to get sufficient 

 force in case of fire. The intake and overflow 

 of the reservoir should also be protected 

 against frost. 



There is still another practicable way of 

 pumping water, and that is by the " air-lift 

 pump." For deep wells this method is emi- 

 nently satisfactory, as it does away with a pump 

 valve entirely, and all the machinery is above 

 ground. The air compression required may be 

 effected by a gasolene engine, electric motor, or
