There are many new uses for water: It will not be 

 Jong before every truck and every commercial flower 

 garden will have overhead irrigation. This is merely 

 gas pipes ("seconds" rejected for blow holes or po- 

 rosity are usually used) supported on posts say six feet 

 above the ground. They are usually placed parallel about 

 fifty feet apart, which will make four to the acre square, 

 and have a single row of holes and a handle on each pipe, 

 so that the spray can be turned in either direction ; with a 

 high-water pressure, often supplied by gravity, they may be 

 farther apart with larger holes. 



These not only have saved us from fear of drought, but 

 they supply the moisture in the natural manner and at the 

 right time and increase fertility to an astonishing degree. 



When you take a shower bath yourself, that is overhead 

 irrigation. 



The gasoline, kerosene, or heavy oil one man farm tractor, 

 so made that it can be used to plow, to climb a side hill, 

 to run a saw or a pump, is the coming factor in garden and 

 farm advance. Huge fortune awaits the first manufacturer 

 who will standardize it, cheapen it, and specialize on it. The 

 horse is the greatest care and the greatest risk on the little 

 farm. He costs more than a tractor would, he is eating his 

 head off hah* the time, he can't be worked overtime without 

 injury, not even as much as a man can be ; all too soon he 

 dies, more missed than any member of the family. 



When this is popularized the "Three Acres" can well be 

 extended to five.
