Most all of these tables have been originated and 

 computed by the author and have been checked in prac- 

 tical work and found to be correct, so that the tables alone 

 will be worth many times the cost of the oook. 



The price of the book has been placed as low as is 

 consistent with the superior quality of the work and it 

 may be obtained on the following terms: $2.50 a single 

 copy, cloth bound; if order is sent with a new subscrip- 

 tion to Irrigation Age or a renewal subscription, the 

 book will be sent and the Irrigation Age one year for

(Continued from page 104.) 



people who are farming on business principles often get 

 a revenue from one crop of fruit far exceeding the total 

 cost of their property. A return of $500 an acre from 

 apple orchards is not uncommon. Cases are cited of or- 

 chardists making as high as $1,000 an acre on fruit. 



Alfalfa, sugar beets and all kinds of vegetables are 

 produced in the Arkansas Valley, with grain farming on 

 a restricted scale. Alfalfa pays $75 to $100 an acre and 

 potatoes and other vegetables from $100 up. I am not 

 interested in booming any locality, and I 'am satisfied from 

 what I saw of the irrigated system that equal profits may 

 be secured by our farmers right here in Illinois, as well 

 as by those in Iowa and the other grain states if they 

 will adopt irrigation and go in for the more modern, in- 

 tensive system of farming such as we see in Idaho and 

 elsewhere, where "organization and system" are first. The 

 Arkansas Valley in Colorado is in a surprisingly high state 

 of cultivation and prosperity, largely through irrigation. 

 I saw the great Teller dam, 30 miles from Pueblo, where 

 they store flood waters which serve to irrigate thousands 

 of acres. I also examined a number of irrigation sys- 

 tems, private and public, between that point and Boise, 

 Idaho. None of those sections could attract immigra- 

 tion after the drought periods which have hit the north- 

 west were it not for pushing the irrigation plan on a sys- 

 tematic and gigantic scale so that all water that falls or 

 comes from meltng snow is conserved and used when 

 needed most. Idaho is growing faster than any other
