or, the average yiekl per acre of protein in tliese eroi)s, is 2. .36 times 

 greater than ih the wlieat bran, the fat 1.52 times greater, and the 

 nitrogen-free extract 1.64 times greater. 



On the basis of cost, very interesting relations are also shown: 

 The average ^'ost per acre of the total nutrients obtained in the 

 protein crops was |12.62. The average cost of a ton of wheat bran 

 at the present time will probably not vary widely from |22. Or, in 

 other words, |1 invested in the group of the protein crops will 

 secure : 



Protein, 60.3 lbs. 



Fat, 10.8 lbs. 



Fiber, 97.7 lbs. 



Nitrogen-free extract, 141.6 lbs. 



One dollar invested in wheat bran will secure: 



Protein, 14.6 lbs. 



Fat, 4 . 1 lbs. 



Fiber, 4.2 lbs. 



Nitrogen-free extract, . .58.2 lbs. 



Or, |1 invested in the protein crops will purchase over four times 

 -as much protein, twice as much fat and two and one-half times aL 

 much nitrogen-free extract as is obtained from wheat bran for the 

 same money. 



It will be seen, therefore, that the advantage from thOvStandpoint 

 of total nutrients is clearly with the protein crops, and more than 

 sufficient to counterbalance the possible increase in digestibility ot 

 the wheat bran, and it is more than likely that the farmer distant 

 from centers of population, may be able to reduce the cost of his 

 nutrients in the protein crops, while on the other hand the cost of 

 his wheat bran may be increased, because of the greater cost of 

 carriage. 



The final point to consider, therefore, is in how far these more 

 bulky protein crops may be able to substitute such products as 

 wheat bran, mainly to supply the needed protein. Experiments
