30. FARM GRASSES OF THE UNITED STATES 
Large seeds, such as those of brome-grass, Johnson 
grass, etc., may be covered more deeply than such 
small seeds as blue-grass, timothy, and the clovers. 
These larger seeds may safely be put down with a 
drill. In light soils seeds as small as clover may be 
sown with a drill. On ordinary soils two inches is 
deep enough to cover large grass-seed, while half an 
inch is deep enough for timothy and clover and other 
small seeds. 
STAGE AT WHICH TO CUT GRASS FOR HAY 
The proper stage at which the grasses should be 
cut for hay has been the subject of much investigation 
on the part of agricultural chemists. The general con- 
clusion to which these investigations have led is thus 
stated by one of our most eminent investigators: 
‘Young plants while rapidly growing contain rela- 
tively more protein and less fibre than more mature 
ones; consequently, early cut fodder must be of better 
quality than that cut late. It is more digestible.’’ 
We have here three facts and one inference. As the 
point is one of much practical importance, we will 
consider it at length. First, the facts are: 
A, Young, growing plants contain relatively more 
protein than mature ones. 
B. They also contain less fibre. 
C, They are more digestible. | 
The inference from these facts is: Early cut fodder 
is of better quality than that cut late. Is this infer- 
ence justified? Concerning the first fact, it may be 
stated that we do not grow the ordinary grasses for 
the protein they contain, and the fact that mature
