216 HORTUS GRAMINEUS WOBURNENSIS. 



But cock's-foot grass perfects an abundance of seed, and the plants 

 arrive at a productive state as soon as those of rye-grass ; hence 

 its superiority over rye-grass, as above, is equally great for perma- 

 nent pasture and the alternate husbandry ; which is not so pre- 

 cisely the case with the fox-tail-grass and meadow fescue. One 

 peck of rye-grass, with 14 lbs. of clover, per acre, is generally 

 considered sufficient for sowing artificial pastures. 



The above details relate to the Pacey's rye-grass ; and the fol- 

 lowing details will shew to a certain extent the superiority of the 

 new varieties. 



1. The Russell's rye-grass. The produce on the 16th of April 



from a brown rich loam is — 



Piuduce per Acre.

 Grass, 8 oz. The produce per acre - - 5445

At the time of flowering the produce is — 

 Grass, per acre _ _ _ - _ 15654 



64 dr. of grass afford of nutritive matter - 3 dr. 733 



The value of this variety, it is perfectly evident, is therefore 

 greatly superior to the Pacey's rye-grass in produce and nutritive 

 properties ; and to these must be added its superior early growth in 

 the spring, and its continuing to vegetate later in the autumn and 

 winter. Tliese properties go near to remove entirely the objec- 

 tions which have been so justly urged against the common rye- 

 grass. 



2. Stickney's rye-grass approaches near to this in its habits and 

 nutritive properties, but I have not had an opportunity to ascertain 

 the produce of it with that degree of precision and certainty which 

 would allow of my giving the results of the trials a place here.

3. The Whitworth's rye-grass is finer in the foliage than either 



of the above varieties.
