necessary, and in any circumstances an agreeable 

 accompaniment. 



I think it will be found that substances peculiarly rich 

 in nitrogenous or other elements have a higher value 

 for special than for general purposes, and that the 

 employment of materials characterized by peculiar 

 properties for the attainment of special objects has not 

 yet gained the attention to which it is entitled. 



I have omitted all reference to the heat-supplying 

 elements — starch, sugar, etc. As the materials com- 

 monly used as food for cattle contain sufficient of these 

 to effect this object, under exposure to some degree of 

 cold, I have a right to calculate on a less consumption 

 of them as fuel, and consequently a greater surplus for 

 deposit as sugar, and probably also as fat, in conse- 

 quence of my stalls being kept during winter at a tem- 

 perature of nearly sixty degrees. 



The means used to carry out his objects are stated 

 on page 138. 



As several of these materials — rape-cake, shorts, 

 bean-straw, etc. — are not commonly used as food, I 

 may be allowed some observations on their properties. 

 Bean-straw uncooked is dry and unpalatable. By the 

 process of steaming, it becomes soft and pulpy, emits 

 an agreeable odor, and imparts flavor and relish to the 

 mess. For my information and guidance I obtained an 

 analysis of bean-straw of my own growth, on strong 

 and high-conditioned land ; it was cut on the' short side 

 of ripeness, but yielding a plump bean. The analysis by 

 Professor Way shows a percentage of

In albuminous matter, which is especially valuable foi 

 milch cows, it has nearly double the proportion con 

 tained in meadow hay. Bran also undergoes a great
