 annual precipitation in representative districts in West- 

 ern Canada for 25 years as compared with that in some 

 other agricultural regions is indicated by the accompany-

as much as in 



some of the older agricultural regions from which our 



settlers have come. 



(2) That nearly the whole of the Canadian west re- 

 ceives more than 13 inches and less than 20 inches per 

 year. 



(3) That the area of lowest precipitation is in south- 

 eastern Alberta and southwestern Saskatchewan, and 

 the supply increases in every direction from this centre. 

 The increase is greater both east and west than north. 



The two chief inferences from the data are, — 1st, 

 that the storage, conservation and efficient utilization of 

 moisture are of very great importance, and .2nd, that 

 extreme practices of "dry farming" would seem de- 

 sirable in the drier areas.
