THE PRACTICAL COUNTRY GENTLEMAN 



for shutting oft the power. The gasolene en- 

 gine, howev'er, Is not suited to running In a 

 house cellar, as the noise Is too great; but for 

 running a deep-well pump, which is operated 

 with a piston rod and consequently has to be 

 set directly over the well, it is most practical. 

 The use of steam is too expensive for a small 

 place and we need not consider it. 



Hot-air engines are strictly pumping-englnes, 

 and as such they have no superior except the 

 electric motor. The principle used is the ex- 

 pansion of air, which is heated by the use of 

 gas, coal, wood, kerosene, or gasolene. These 

 engines can be run at very small cost, a quart of 

 kerosene or four pounds of coal being sufficient 

 for an hour's pumping. 



A suction pump may be used if water is taken 

 from a shallow well where the vertical lift is 

 not over twenty or twenty-five feet, and in 

 that case the engine and tank can be in- 

 stalled In the cellar; otherwise a pump house 

 must be built. The cost of a hot-air engine, 

 capable of pumping 300 gallons per hour to a 

 height of seventy-five feet (which is estimated
