fourth of the vahie of the. whole crop is sustained 

 if it is not cut till that period : the straws areiiien 

 dry, and the root-leaves in a sicUly decaying stale; 

 those of the latter-uiath, on llie conlrar\', are lux- 

 uriant and heahiiy. This species sends forih 

 flower-stalks but once in a sea>^on ; and these he- 

 ing the most valuahle part of the plant for the 

 purpose of liay. it will, from this circumstance, and 

 the superior value of tiie grass of the lalier-math 

 compared to that of the seed-crop, appear well 

 adapted for permanent pasture.

If the produce of this variety be compared with

 nor does it seem to possess any superior excel-

 make up for the deficiency of produce by 80 lbs. 

 of nutritive matter per acre.

This is rather an early grass, though later than 

 any of the preceding species ; its foliage is very 

 fine, resembling the P. duriuscula, to which "it 

 seems nearly allied, differing only in the length of 

 the awns, and the glaucous color of the whole 

 plant. The considerable produce it affords, and 

 the nutritive powers it appears to possess, joined 

 to its early growth, are qualities which strongly 

 recommend it to further trial. °

The proportional value in which the grass of 

 the seed-crop exceeds that at the time of flower- 

 ing, is as 8 to 11.

The proportional value by which the grass of 

 the latter-math exceeds that of the flowering 

 crop, is as 8 to 12, and that of the seed-crop as 11 

 to 12. ' 



Here, then, is a satisfactory proof of the supe- 

 rior value of the crop at the time the seed is ripe, 

 and of the consequent lo.s-s sustained by taking it 

 whenin flower; the produce of each crop bein-r 

 nearly equal. The deficiency of hay in the flow- 

 ering crop, in proportion to that of the seed-crop, 

 13 very striking. Its superior produce, the highly 

 nutritive powers which the grass seems to possess, 

 and the season in which it arrives at perfection, 

 are merits which distinguish it as one of the most 

 valuable of those grasses which aflect moist rich 

 sods and sheltered situations; but on dry exposed 

 situations it is altogether inconsiderable : it yearly 

 diminishes, and ultimately dies off", not unfre- 

 quently in the space of four or five years.
