CHAPTER IX. 
CLOVERS. 
Common Red Clover (Zrifolium pratense, Linn.). Single-cut Cow Grass, 
or Perennial Red Clover (77ifolium pratense perenne, Sutt.). Zig- 
Zag Clover (7r7folium meatum, Hudson). Woodland Cow Clover 
(Trifolium pratense, var. Sylvestre, Syme). 
asked, “What is perennial cow grass?” few 
farmers would venture to reply; if they did so 
their answers would be evasive or qualified. 
We have searched the authorities from Sinclair 
in 1816, and, as a result, we are induced to state our 
deductions, in the hope that others will follow in our footsteps, 
and thus further light may be thrown upon a most interesting 
question. 
We would convey our warmest thanks to many of our 
friends who have written us in reference to this involved 
problem, especially to Mr. Martin Sutton, from whom we 
have received valuable information; his remarks upon cow 
grass, which the reader will find at the end of this chapter, 
should prove of the greatest interest and value to all. 
Although seven years ago we were somewhat opposed to 
his argument, we have since been converted, which result has 
been partly brought about by practical experiments and obser- 
vations of our own.
