232 FARMING ON FACTORY LINES 



others, who have written on the feeding of farm 

 animals, have always had at the back of their minds 

 the very high cost of albuminous foods, which under 

 the ordinary system means, in practice, the purchased 

 foods. Hence, in compounding rations the general 

 recommendations would be to keep the albuminoids or 

 proteins in a food at the minimum, but in the Con- 

 tinuous Cropping System we grow a large amount of 

 cheap albuminous food, and strict economy in its use 

 is not so essential.
