receive only a small amount, from 5 to 10 

 inches, during the growing season. In 

 such a case the crop will undoubtedly 

 suffer from drought unless the moisture 

 of the previous part of the season has

 he would point out that dry-farming is 

 the key to closer settlement, and as such 

 should receive the cordial support of all 

 those interested in schemes of coloniza- 

 tion. Nor should we forget that the dry- 

 lands are the healthy lands, and are 

 therefore eminently suited to land set- 

 tlement. Dry-farming, if properly car- 

 ried out, can never fail, for it is based on 

 thorough tillage — the supreme principle 

 of all successful agriculture.
