Jordan and Hall give a bine joint under meadow grasses. I 
do not know whether this is our blue joint or not, but for this they 
give the following coefficients: 
Dry Matter. Ash. Fat. Protein. Fibre. Extract. 
Maximum . 68.6 48.7 52.3 70.2 72.4 68.6 
Minimum . 39.9 10. o 37.0 56.5 36.5 43.2 
Average . 54.3 29.4 44.7 63.4 54.5 55-9 
This blue joint is probably Calcimagrostis canadensis , 
while our blue stem is Agropyron tenerum. I know of no data 
on this subject applicable to our native hay, unless the compari¬ 
son be made under the very broad head of meadow hay, which is, 
perhaps, a little too broad. 
The native hay used in this experiment was purchased in the 
market as “upland hay.” It was said to have been cut on the 
farm of Mr. Gilkison and was composed largely of blue joint 
Agropyru 7n ten eru m . 
I do not think that the coefficients of digestion of this class 
of hay have been determined, at least I can find none. 
Such hay is cut from the bottom lands along the water courses, 
or where water courses have been and the supply of moisture 
is both greater and more constant than in the higher ground. It 
can scarcely be compared with Eastern meadow hay, though such 
a comparison would, in a measure, be justified.
