The strong nutritive powers which this grass 

 possesses recoininenil it to the notice of occupiers 

 of strong clayey lands which cannot be drained. 

 Its produce is great, and the foiiajie will not be 

 denominated coari<e, if compared with those which 

 afford a produce equal in (|uantity.

If the weight which is lost by the produce o( 

 <his species of clover, in drying, be compared with 

 that of many of the natural grasses, its inferior 

 value for the purpose of hay, compared to its va- 

 Jue for green food or pasture, will appear; for it is 

 certain that the difficulty of making good hay in- 

 creases in proportion with the quantity of super- 

 fluous moisture which the grass may contain. Its 

 value for green food, or pasture, may further be 

 seen by comparing its nutritive powers with those 

 manifested by other plants generally esteemed 

 best for this purpose.

The grass of the T. pratense, therefore, exceeds 

 in value that of the T. repens by a proportion as 

 8 to 10; but it is of equal proportional value with 

 the brown variety.

 The proportional value of these two last, and of 

 the T. pratense, and the brown-leaved variety of 

 T. repens, are equal: they exceed the T. repens 

 as 8 to 10. 



The comparative produce of these four last- 

 mentioned species, per acre, has not been ascer-

The root of this species of clover is biennial ; 

 it penetrates to a great depth in the ground, and is 

 in consequence little affected by the extremes of 

 wet or dry weather. It requires good shelter, and 

 a deep soil. The produce, when compared to 

 that of others that are allied to it in habit and place 

 of growth, proves greatly superior. The follow- 

 ing particulars, some of which refer to results 

 staled in the next two pages, will make this mani- 

 fest :—

The proportional value of the grass, like that 

 of the T. pratense, is as 11 to 10. 



The produce of each of the above-mentioned 

 species was taken from a similar soil, and in the 

 same situation; the conclusions must therefore be 

 considered positive with respect to such soils only. 

 It is evident that more than twice the quantity of 

 nutritive matter is afforded by the produce of one 

 acre of the T. macrorhizum, than from the pro- 

 duce of an equal space covered by the T. pra- 

 tense. Its short duration in the soil (for if sown 

 early in the autumn, on a rich liiiht soil, it is only 

 an annual plant) renders it fit only for green-Jood 

 or hay; this in some measure lessens its value 

 when compared with the T. pratense. It possess- 

 es the essential property of affording abundance of 

 good seed; and if the ground be kept clear of 

 weeds, it sows itself, vegetates, and grows rapid- 

 ly, without covering-in, or any operation whate- 

 ver. For four yeafs it has profiagated itself in 

 this manner, on the space of ground which it now 

 occupies, and from which this statement of its 

 comparative value is made. The produce of lu- 

 cern in grass comes nearer to this species in quan-
