Ration No. 13 was a small one in both its digestible protein 
and its fuel value. Ration B differs from A principally in con- 
taining a pound more of cotton seed meal and some less hay. It 
contains a little less digestible protein and its nutritive ratio is a 
little wider than that suggested on page 100. Ration C contains 
less wheat middlings and ensilage and more corn meal and hay 
than either A or B. It is a well balanced ration. of about the 
proper size. Each of the rations B and C isa little more expen- 
sive than A.

Ration No. 14, as fed, is a little larger than the standard calls 
for, but is fairly well balanced. The use of quite large quanti- 
ties of hay makes the ration somewhat expensive. Ration Bisa 
well balanced ration of the standard size, costing only 19 cents. 
This low cost is due to the use of stover alone for coarse food. 
If some other material than oat feed were used, the ration
