SOME COLORADO GRASSES. 
In the analyses the moisture had the least variation, 
ranging from a little over 3 per cent, to a little over 
13 per cent., the majority ranging from 7 per cent, to 
9 per cent. 
The lowest ash is 4.51 per cent. There are forty- 
eight samples 9 per cent, and over, and seven samples 
over 15 per cent, of ash. 
The fat ranges from 1.13 per cent, to 9 per cent. 
The 9 per cent, fat was duplicated and contained a 
large cpiantity of gum, etc. Thirty-eight samples con¬ 
tained over 3 per cent, of fat. 
The albuminoid nitrogen ranged from 3.8 per cent, 
to 20.98 per cent. But seventeen specimens had over 
12 per cent. 
The lowest crude fiber was 11.10 per cent.; the 
highest 38.06 per cent. Fifty-seven samples were over 
18 per cent. 
The lowest nitrogen-free extract was 44.24 per cent.; 
the highest was 68.83 per cent.; the average from 50 
per cent, to 60 per cent. 
The average of all the analyses was as follows: 
Moisture 9.53 ; ash 9.43 ; fat 3.15 ; albuminoid nitrogen 
9 ; crude fiber 19.60. In the analyses it was a singular 
fact that those that gave good results were plants of 
small size.
