ANIMAL INDUSTRIES 209 



animals need not be expected to depress the fruit 

 industry, for the relations of the two are reciprocally 

 beneficial in many ways. Especially in the line of 

 producing animal manures which are coming into 

 increasing appreciation for use on fruit lands, the 

 live-stock industry may be considered as fundamental 

 and indispensable. 



In connection with the total value of $234,000,000 

 of farm animals, the total annual value of marketed 

 products is also interesting and it may be compiled 

 from the data in Chapter IV in this way: 



VALUES OF CALIFORNIA ANIMAL PRODUCTS 



Slaughtering and meat-packing (1919) $84,000,000 



Dairy manufacture and milk sale (1919) 74,515,381 



Wool ( 1917 ) 12,180,000 



Therefore, without counting the value of the manu- 

 rial by-product and the locally consumed products on 

 farms and in villages, there appears to be an annual 

 gross product value of $170,695,381 from an invest- 

 ment of $234,000,000 in value of farm animals. Of 

 course the product value covers use of land and 

 cost of labor and supplies, as well as a fair return on 

 the investment, which is all that is expected of a 

 prosperous industry. 



A categorical statement of the natural conditions 

 affecting the live-stock industry in California with 

 indication of their relation to policies and methods 

 may be undertaken in this way : 



1. The absence of snow and ground freezing, 

 except on mountain valleys or plateaux, renders light
