proportional value; a circumstance which will point 

 out this grass to be more valuable for permanent pas- 

 ture than for hay. The above details prove, that a 

 loss of nearly one third of the value of the crop is sus- 

 tained, if it is left till the period when the seed is ripe, 

 though the proportional value of the grass at that time 

 is greater, /'. e. as 7 to 5. The produce does not in- 

 crease if the grass is left growing after the period of 

 flowering, but uniformly decreases ; and the loss of 

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

 foliage after the grass is cropped) is very considerable* 

 These circumstances point out the necessity of keep- 

 ing this grass closely cropped, either with the scythe 

 or cattle, to reap the full benefit of its great merits.
