It ought to be mentioned, perhaps, that these samples 
are from different places, some grown with and others 
without irrigation on different soils. With the exception 
of analysis No. 4, first cutting, the results indicate that 
the nitrogen free extract is greatest at or about full bloom.

The moisture in our samples of air dried hay ranges 
from 4 per cent, to nearly 9 per cent.,with an average of 6.21 
per cent., for the first; 5.94 per cent., for the second and 5.93 
percent.for the third cuttingpvhile the average for all three 
is 6.03 per cent. Such hay takes on moisture readily. While 
preparing our first cutting samples, we had a spell of damp 
weather lasting from July 3d to 6th, during which some sam¬ 
ples gained as much as 5.70 per cent. The smaller samples 
gained more proportionately than the larger ones because 
There was relatively more surface exposed. 
The moisture in the farm samples is higher than in the 
laboratory samples. This is noticeably the case with the
