+ See Professor Johnson’s statement in ‘Sixth Report of the Sec. Connecticut 
Board, of Agriculture,” 1872, p. 422. The amount of water actually found in 
this sample is not given. But in order that the results of the analysis may be 
readily compared with the others, I have recalculated Johnson’s figures on the 
assumption that his hay contained 8% of water. 
It is noteworthy that the proportion of moisture contained in most of the 
hays and plants described in this article is decidedly smaller than the amounts 
that have ordinarily been reported by European analysts. (See, for example, 
the tables in Johnson’s “‘ How Crops Grow,” page 385.) It would perhaps be 
premature to assert that this difference is due solely to the extreme dryness 
of the air in New England during winter, for it may be that the plants analyzed 
above were exceptionally dry, and that (as seems probable) the,mechanical 
texture of the bog hays is not favorable for the retention,of moisture. There 
can be little doubt, however, in view of the dryness of our climate, that hay is 
in general actually drier here in New England during the winter, and probably 
at all times, than it is in Germany and in England. I hope to study this point
