 that may be reached by a driven well. 



I much prefer to pump from wells in all cases, 

 because in the summer the water from ponds or 

 rivers is quite warm, while that from wells is 

 cool, and this coolness will be an advantage to the 

 crop, especially if the ground is very dry and hot, 

 as is often the case; and again in winter, if taken 

 from ponds or rivers, is very cold, and could not 

 be put upon the plants until it had been warmed, 

 while that taken from wells would be at a proper 

 temperature to be applied immediately. For 

 these reasons I have always preferred the wells; 

 and have always used them. 



Pumps used for irrigating are of three kinds, 

 depending on their motive power, namely, wind- 

 mills, steam pumps and gasoline pumps. For those 

 who can afford the outlay it is much the better 

 plan to have a windmill with either of the others. 



The windmill will do the cheapest pumping 

 but when it does not pump a sufficient quantity 

 then the other motive power can be used. 



My experience with steam power has been 

 much more extensive than with gasoline engines, 

 and for that reason in the following pages I will
