Station — has been thoroughly revised, and some feeds that 

 are no longer on the market or were of only temporary 

 interest have been omitted. This is especially true of a 

 number of concentrated by-products, where the process of 

 manufacture has been noticeably changed and improved. 



Tables showing the coefficients of digestibility of all 

 American feed stuffs, similar to those published in the ninth 

 report , are also presented. Work of this nature requires a 

 great amount of time, and severely taxes the resources of 

 the station staff.
