IIORTUS GRAMINEUS WOBURNENSIS. 151 



constitute a much smaller proportion of the vveight of the 

 crop than in the flowering crop. It may be observed here, that 

 there is a great difference between culms and leaves of grasses that 

 have been dried after they were cut in a green and succulent state, 

 or in possession of their nutrient qualities, and those culms and 

 leaves which have been dried (if I may so express it) by Nature 

 when growing : the former retain all their nutritive powers, but the 

 latter very little, if any. In point of early produce in the spring, 

 this grass stands next to the A/opecuras pralei/sis, (meadow fox- 

 tail), and is superior in this respect to the cock's-foot.

It is eaten by horses, oxen, and sheep, but particularly by the 

 two first : its merits will be more clearly seen by comparing it far- 

 ther with the cock's-foot and meadow fox-tail. As it is often three 

 weeks later in flowering than the fox-tail grass, the latter-math 

 produce roiust be left out for the truth of comparison as regards its 

 comparative value for hay ; and as it is much slower in growth 

 after being cropped than the cock's-foot, it is likewise necessary 

 to omit the latter-math in a comparison of their produce.
