The proportional value which the ^rass at the 

 lime offlowering bears to that at the time the seed 

 is ripe, is as 5 to 7, nearly. 



The produce of latter-math is — 



oz. or lbs. per acre.

The proportional value which the grass of the 

 latter-math hears to that at the time of flowering 

 is as 6 to 10 ; and to that at the time the seed is 

 ripe, as 6 to 14. 64 dr. of the straws at the time 

 of flowering afford of nutritive matter 1.2 dr. The 

 leaves or latter-math, and the straws simply, are 

 therefore of equal proportional value ; a circum- 

 stance which will point out this grass to be more 

 valuable for permanent pasture than for hay. The 

 above details prove, that a loss of nearly one-third 

 of the value of the crop is sustained if it is left till 

 the period when the seed is ripe, though the pro- 

 portional value of the grass at that time is greater, 

 i. e, as 7 to 5. The produce does not increase if 

 the grass is left growing after the period of flow- 

 ering, but uniformly decreases; and the loss of 

 latter-math, which (from the rapid growth of the 

 foliage after the grass is cropped) is very consider- 

 able. These circumstances point out the necessity 

 of keeping this grass closely cropped, either with 

 the scythe or cattle, to reap the full benefit of its 

 great merits.

This species is nearly allied to the Festuca ovi- 

 na, from which it diflers little, except that it is 



larger in every respect. The produce, and the 

 nutritive matter which it afibrds, will be found su- 

 perior to those given by the F. ovlna, if they are 

 brought uito comparison.

This species, like the preceding, is strictly an-

 year, which, if compared with that of the least 

 productive of the perennial grasses, will be found 

 inferior, and it must consequently be regarded as 

 unworthy of culture.

In the early growth of the leaves of this spe- 

 cies of Poa there is a striking proof that early 

 flowering in grasses is not always connected with 

 the most abundant early produce of leaves. In 

 this respect all the species which have already 

 come under examination are greatly inferior to 

 that now spoken of. Before the middle of April 

 the leaves attain to the length of more than twelve 

 inches, and are soft and succulent; in May, how- 

 lever, when the flower-stalks make their appear- 

 lance, it is subject to the disease termed rust,
