The table shows that the heavier hogs made more rapid 
gains and consumed less feed per 100 pounds of their live

Fig. 54.) 
A similar result was obtained at the Ontario Agricultural 
College with 36 pure-bred pigs of auenent breeds, as shown by

These figures, together with others that might be given,

Correctives.—Swine appear to have a craving for what 
might be called “ unnatural” substances. This is especially 
true of hogs which are kept in confinement, which will eat 
greedily such substances as charcoal, ashes, mortar, soft coal, 
and rotten wood. It is probable that some of these substances
