Author's Note 



IN the preparation of the following series the writer has 

 endeavored to give in clear, concise language the appli- 

 cation of science to practical feeding. In many cases 

 the material has been written hurriedly without attempt 

 at finished production, because the whole series has been 

 written at odd times, as the duties of classroom and labora- 

 tory would allow. In every case it has been the intention to 

 state no principle or practice that has not a firm place in the 

 operations of our best dairy feeders. 



In this time of stress the feeding of our animals is diffi- 

 cult.' It is hoped that these articles may help feeders to get 

 a firm basis on which to start their plans. The author hopes 

 that after they are carefully read that they may be the stimu- 

 lation which will cause the reader to study further the prac- 

 tice of other men and to correlate this practice with his own 

 methods.
