This long table shows how much dry matter there is in 100 pounds of 

 each of the feeding stuffs named. Following this we learn the pounds of di- 

 gestible protein, carbohydrates and ether extract in 100 pounds of each and 

 all of the feeds. One hundred pounds of corn, for example, the first article in 

 the table, contains an average of 7. 9 pounds of digestible protein. The diges- 

 tible carbohydrates, mostly starch, reach the large aggregate of 66.7 

 pounds, while the digestible corn oil or ether extract amounts to 4.3 pounds. 

 These three sums added together do not make 100. A part of the difference 

 is water, and the remainder is made up of the indigestible portion and the 

 ash. The reader is urged to study the data of the table in order to familiarize 

 himself with the characteristics of the different feeding materials avail- 

 able in this country. He will see that such feeds as bran, gluten 

 meal, linseed oil meal, cottonseed oil meal, buckwheat middlings, etc., are 

 all rich in protein but carry no large percentage of carbohydrates. On the
