By combining the various classes, as in the table below, the 

 differences in the composition are more clearly brought out. It 

 will be seen that of the three classes, Dent, Flint, and Sweet, the 

 Flints have the largest percentage of dry matter and the Sweets 

 the least ; the Sweets have a slightly higher ratio of protein 

 matter. The Dents have somewhat more water than the Flints 

 and considerably less protein, but in general they give a much 

 larger amount per acre both of green forage and dry matter, as will 

 be seen by reference to Table III. It is interesting to note 

 that the Kaffir Corn, with a moderate amount of water, has a 

 much higher proportion of protein than an)' of the three classes 

 mentioned. It did not, however, make a large growth of green 

 fodder. All things considered, it seems to us that that variety of 

 Dent corn that will approach fairly well toward maturity, in ordi- 

 nary seasons in the locality, is the best for ensilage purposes.

In Table III is given the yield in pounds per acre of the 

 green forage, the dry matter, and the several nutritive constitu- 

 ents of all the varieties planted in tenth-acre plots. The varieties 

 are arranged in the order of the dry matter per acre produced. 

 The numbers at the left refer to the numbers in Table I. 

 It will be seen that there is no relation between the amount of 

 green forage and the amount of dry matter. Though the very 

 immature Brazilian Flour corn from its immense growth did pro- 

 duce the greatest amount of dry matter, there were four varieties
