AGRICUJLTUKAI. CONDITIONS. 



A well-kuown writer speaks of the agricultural resources of the 

 Rocky Mountain region as follows: 



Generally speakiDg, those best acquainted witli the West make tlie largest esti- 

 mates of its resources and haye the most faith iu its future. Land, on first sight, of- 

 ten appears worthless, yrhich experiment afterwards proves to he fertile. I instance 

 the "Great Columbia Plains" of eastern Washington, where the soil, which varies 

 from 1 foot to 20 in depth, is, except in the bottom-lands, a very light-colored loam, 

 containing an unusually large percentage of alkalies and fixed acids. A few years 

 ago sowing wheat on the soil woul d haTe been deemed throwing it away; but the 

 experiment resulted in a revelation, viz, that these 14,000,000 acres of peculiar soil 

 are probably the best wheat fields in all the world. Other illustrations equally strik- 

 ing; might be given. » * * "
