or the other raised exclusively. The exception to this 
rule is found in localities where milk condensers have 
been developed so that there are few by-products of the 
dairy business which can be utilized in pig feeding. 
Swine fattening differs from cattle fattening in that it 
is conducted largely on the farm where the hogs were 
raised, while in the case of cattle, the fattening process 
is often carried on at a long distance from the farms 
and ranges on which the cattle were grown. In the 
West the practice of fattening hogs after beef cattle is 
unknown, since hay-fed cattle contribute nothing to pigs 
through their droppings, and grain feeding is not prac- 
ticed here as in the Corn-Belt. Hence, hogs and beef 
cattle do not supplement each other as do hogs and dairy 
cattle. Many farms in the Willamette, Valley carry 
both hogs and sheep, but there is little relation between 
the two lines of industry and neither of them contrib- 
utes anything material to the other. Hogs are also 
rapidly making a place for themselves on the large grain 
farms of the West, for they fit in well with the common 
systems of farming and they utilize the down grain and 
the waste of the threshing yards.

recurring each year at approximately the same time. 
When the supply goes down, the price goes up, and 
vice versa. This rule is not without exception but it 
holds in a greater number of cases. The packer demands 
the largest number of hogs during the months of Novem-
