If, then, we know tlie number of pounds of each of these constitu- 

 ents in a hundred-weight of an " average grain,'' we can find the value 

 of each per pound by dividing the value in cents per hundred- weight by 

 the pounds per hundred- weight. 



It remains, therefore, to determine as accurately as possible the aver- 

 age content of American cereals in these substances that give them 

 their food value, the ^"nutrients," viz: albuminoids, fat, and carb- 

 hydrates. 



The following averages have been drawn from the most reliable re- 

 corded American analyses. The most of them have been taken from the 

 valuable " Eeport of the Connecticut Agricultural Experiment Station," 

 for 1879, which contains all the later American analyses from various 

 sources. The average figures for rice are taken from the results of analy- 

 ses this year, made at this department, of ten varieties sold in American 



markets.

The figures above used for rye and barley will probably be slightly 

 changed when more analyses have been made. Buckwheat was not in- 

 cluded in this list for lack of authenticated analyses of American sam- 

 ples. It is pretty certain, however, that its composition does not vary 

 greatly from the above average. Oats were not included, because of 

 their much greater amount of fiber, which proportionately reduces the 

 amount of nutrients.
