Composition and Nutritive Value of Strain. 
Stubble, then, contains as much nitrogenized matters as straw, 
which it ch)sely resembles in other particular's, the chief differ- 
ence beinp; its somewhat smaller proportion ol oil. 
It has been stated hy practical men that stubble has no direct 
value as a manure, and not much as litter. If this be so, it 
lollows inevitably that wheat-straw has no direct value as a 
manure, for both straw and stubble contain as nearly as possible 
the same proportions of nitrogenized and carbonaceous and 
mineral matters. 
Barley-Straw. 
Barley, especially if good malting barley, is generally allowed 
to turn more yellow in the field than any otlier grain -crop. The 
barley-straAv on our farms, therefore, is seldom so nutritious as it 
might be, if the crop were cut down in a less advanced stage of 
maturity. The following analysis was made of barley-straw, 
which I am inclined to term dead-ripe, although it is the usual 
condition in which it is seen in our neighbourhood : —

These results suggest one or two remarks. 
In the first place : That the appreciable quantity of oil contained 
in barley, as in wheat-straw, must contribute to its nutritive 
value. 
Secondly : That the amount of sugar, gum, and other soluble
