laiiy bj ruminants, and from the results obtained regard- 

 ing the digestibility of straw, etc., as well as from its com- 

 position, it is evident that the digested portion would be 

 chiefly earbhydrates, with but little protein or fat. 



The connuon method of using cobs as feed is to grind 

 them with the grain, making "cob meal." Some recent 

 practical trials '^ seem to indicate that the same nutritive 

 effect may be produced by a less quantity of the kernel 

 when the latter is fed along with cob as cob-meal, the dif- 

 ference being made up by the digestible matters of the 

 cob. The latter, as has been said, probably consist chieiiy 

 of earbhydrates ; their effect would be to widen the nutri- 

 tive ratio of the ration, and thus to favor a more economi- 

 cal production. Unfortunately, these experiments did not 

 include analyses of the fodder used, and hence their results, 

 though interesting as indications of the digestibility of 

 maize cob, are not suited for elaborate discussion here.
