The table on page 35 points out the cheapness, at the assumed prices, of 

 a pound of digestible nutrients in corn meal, cob meal and hominy chop 

 and the considerable cost of the same in oats and oatmeal mill products. 

 Similarly, among the richer feeds, it discriminates against the linseed pro- 

 ducts. The feeder who wishes digestible dry matter, and who does not 

 want relatively more protein than carbohydrates, may use this table to ad- 

 vantage. He, however, who needs protein more particularly, may be mis- 

 led if he pins too much faith on this table; but he may find the one on this 

 page more helpful. This shows the costly character of the starchy feeds as 

 sources of protein supply and the relative cheapness of cottonseed meal and 

 the glutens. 



It hardly need be pointed out that the buyer of feed can improve upon 

 either of these tables for himself by substituting local values for such feeds 

 as he has under consideration. Thus, for example, if old process linseed 

 meal were sold at $23, the first figure would become 1.15, the sixth 0.92,
