If the weight which is lost by the produce of this 

 Species of clover, in drying, be compared with that of 

 many of the natural grasses, its inferior value for the 

 purpose of hay, compared to its value for green food, 

 or pasture, will appear; for it is certain that the diffi- 

 culty of making good hay increases in proportion with 

 the quantity of superfluous moisture which the grass 

 may contain. Its value for green food, or pasture, 

 may further be seen by comparing its nutritive powers^ 

 with those manifested by other plants generally esteem- 

 ed best for this purpose.
