WATER SUPPLY AND PUMPS 



crops, including milk, the value of an inexhaust- 

 ible water supply can be readily appreciated. 



On a farm of moderate size the supply of 

 water will be derived from a spring, a well, a 

 brook, a pond, or a reservoir. In the majority 

 of cases a shallow well or spring will supply the 

 drinking water, while a cistern at the barn serves 

 for watering the stock. 



Before the supply system that is to be in- 

 stalled is decided on, the water should be care- 

 fully analyzed and also tested for the quantity 

 yielded in twenty-four hours. That people be- 

 come immune to bad water is notorious; for on 

 many farms where a well is near the stable or 

 hog-pen, no evil effects are felt by the owner 

 from drinking such water, but let a passerby, 

 used to pure, wholesome water, drink from the 

 same source, and ten chances to one the conse- 

 quences are disastrous. 



A driven well, made either by driving an iron 

 pipe with a pointed perforated shoe attached 

 where the ground is not rocky, or by the use 

 of especial well tools and steel-pointed drills 

 where it is rocky, is much safer for drinking
