The weight of nutritive matter which is 



lost by leaving the crop till tiic seed is 



ripe, being nearly one-third part of its 



value 1435 11 2 



The proportional value which the grass at the 

 time the seed is ripe, bears to that at the time of 

 flowering, is as 12 to 18. 



This grass, as has already been remarked, pro- 

 duces a fine early foliage in the spring. The pro- 

 duce is very great, and ils nutritive powers are 

 considerable. It appears, irom the above particu- 

 lars, to be best adapted for hay. A very singular 

 disease attacks, and sometimes nearly destroys, 

 the seed of this grass: the cause of this disease 

 seems to be unknown ; it is denominated Ciavus 

 by some ; it appears by the seed swelling to three 

 times its usual size in length and thickness, and 

 the want of the carcle. Dr. Willdenow describes 

 two distinct species of it : 1st, the simple ciavus, 

 which is mealy and of a dark color, without any 

 smell or taste ; 2dly, the malignant ciavus, which 

 is violet blue, or blackish, and internally too has a 

 bluish colo.-, a foetid smell, and a sharp pungent 

 taste. Bread made from grain affected with this 

 last species is of a bluish color ; when eaten, pro- 

 duces cramps and giddiness.

The proportional value which the grass, at the 



time of flowering, bears to that at the time the 

 seed is ripe, is as 6 to 14. 



This species greatly resembles the preceding in 

 habit and manner of growtli, but is inferior toil 

 in value, which is evident from the deficiency of 

 its j)roduce, and of the nutritive matter afforded by 

 it. The whole plant is likewise coarser, and of 

 greater bulk in proportion to its weight. The 

 seed is aflected with the same disease which de- 

 stroys that of the former species.

This species of fescue is closely allied to the 

 Festuca pratensis, from which it differs in little, 

 except that ii is larger in every respect. The pro- 

 duce is nearly three times that of the F. praten- 

 sis, and the nutritive powers of the grass are su- 

 perior, in direct proportion, as 6 to 8.
