The average compositiou of American grasses as derived from the 

 preceding analyses of grasses in bloom and averages for different sec- 

 tions of the country, has been calculated. The results presented in 

 the following table, with Wolff's averages for German grasses, are of 

 interest :

The different sections furnish very different qualities of grasses, and 

 for the reason that those from the I^orth were almost entirely from cul- 

 tivated soil, while those from the other sections were many or most of 

 them wild species from old sod. The improvement brought about by 

 cultivation is marked and the difference between a ton of wild AYestern 

 and Eastern cultivated hay is apparent. 



In comparison with German grasses our best do not equal in amount 

 of albuminoids those classed by Wolff as fair, but they are far superior 

 in having a much smaller percentage of fiber and consequently" a larger
