purposes than shallow wells; for the water is 

 then taken from a lower stratum, and there Is 

 but little chance of contamination. The first 

 thing to be considered after the source of supply 

 Is decided upon Is the way In which water should 

 be stored; and as a medium-sized farm of about 

 sixty to seventy-five acres needs sufficient water 

 to provide for a family, say, of five, In addition 

 to ten cows, two horses, ten pigs, and six hun- 

 dred fowls, besides watering the lawns, flowers, 

 etc., ample storage room should be provided. 



There are four different ways of storing 

 water In general use: In tanks of wood, steel, 

 or concrete set on steel or concrete supports; 

 In reservoirs, made either of earth or concrete, 

 and built partly In an embankment and partly 

 above ground; In wooden tin-lined tanks placed 

 In the attic; In air-tight tubular steel tanks, Into 

 which air is forced with water, creating a pres- 

 sure that forces the water through the delivery 

 pipe. The advantages and disadvantages of these 

 four ways can be briefly summed up. Wooden 

 tanks are Inexpensive, but liable, of course, to 

 shrink if they remain empty any length of time.
