 by the use of naphtha or other solvent. The naphtha is 

 removed by steam, and the dried material furnishes what 

 has been known as the new process linseed meal. Flax 

 meal is the particular name of new process meal put out by

 feed. The brand or brands highest in protein and lowest 

 in fat are to be preferred. Linseed meals are generally 

 known as oil meal. This is an incorrect name, the oil in 

 many cases being very thoroughly removed. 



Pea and bean meals are high in protein and fat. Peanut 

 meal is very high in })rotein. They are all valuable feed 

 stuffs, and quite generally used in European countries.
