How this amount of albuminoids, etc., may be obtained, I present the fol- 

 lowing tables, partly obtained from Dr. Wolff's as given in How Crops Grow,. 

 and partly from results of analysis of materials at our college : 



Timothy, cut in blossom 



Average of all the grasses 



Wheat straw 



Eye straw 



Oat straw 



Corn stalks 



Potatoes 



Rutabagas 



Bran, 60 cents per 100 lbs 



Shorts, 80 cents per 100 lbs.... 

 Middlings, $1.00 per 100 lbs... . 



Millfeed, $1.10 per 100 lbs 



Ground feed, $1.25 per 100 lbs 



Average of yellow corns 



Average of white corns

These tables will pay for careful study. For example, you find from the 

 table that an ox at rest requires .'.) pounds of albuminoids and 7.3 carbohydrates 

 daily to keep him in condition ; the ratio of albuminoids is 1 to 8 of carbohy- 

 drates. In good timothy liay the ratio of albuminoids to carbohydrates is 1 to 

 5, and such hay tlierefore contains a greater proportion of albuminoids tiian is 

 required to keep an ox in condition when at rest. The ratio in wheat straw is 

 1 to 15, which therefore contains less of the albuminoids than is required to 

 keep the ox in condition and enable him to digest all the carbohydrates con- 

 tained in the straw. If timothy liay and wheat straw are combined in proper pro- 

 portions, tlie ox will be as well sustained as he would be when fed on hay alone, 

 and the more perfect digestion of bath hay and straw will be secured. If the
