 equitable market prices for these articles, not that nitrogen is worth 

 twice as much as soluble phosphoric acid lor making crops. In the 

 future more exact valuations may be obtained from an extensive review 

 of the resources of our markets, in connection with the results of analy- 

 ses of the feed and fodder consumed on our farms.

* Except those in italics, which are American products analyzed under direction of Professor Johnson. 



Comparing the poorer foods, such as straw, cornstalks, and inferior 

 hay with a good standard food like the best hay or pasture grass, it ap- 

 pears that the great difference is that the former lack albuminoids, just 

 what bran, oil cake, cottonseed cake, and especially fish, supply. One 



* Fat and carbohydrates have, it is believed, similar nutritive functions, and it is 

 assumed that 1 part of fat equals 2.4 of carbohydrates.
