 which had been considered too alkaline for 

 agriculture of any sort. 



Stock-Raising. This is the more important 

 phase of agriculture in Arizona, for much of 

 tin- land which is too dry for the production 

 of crops has a fine growth of grasses, some of 

 which seem to be remarkably independent of 

 moisture conditions. Thus some of the most 

 typical of the great western cattle ranches are 

 in Arizona, chiefly in the northern plateau 

 region. Most of the cattle are grown for 

 market and not for dairy purposes. Sheep- 

 raising is increasingly important, there t>< 

 over a million and a half of sheep on tin- 

 ranges, and in production of wool Arizona is 

 among the first dozen states. With the growth 

 of irrigation projects the cattle industry is 

 certain to decline as agriculture increases, but 

 the change will be slow. 



Minerals. The great wealth of Arizona lies 

 in its minerals, few if any of the states sur- 

 passing it in the richness of its deposits. Some 

 of tin mines have been worked since the early 

 Spanish occupation of Mexico, or over 900 

 n, luf until the last few years mining has 

 not been highly developed, owing largely to 

 the lack of transportation facilities. To-day
