(TrifoUum procumhens), are, at least as far as my observations have extended, tlie only pla,t, 

 beside, that retain verdure and powers of growth under such circumstances. There were 

 favourable opportunities during the long-continued season of dry weather in this year, (isig)^ 

 to observe the powers of different grasses and plants to resist the effects of drought: there 

 were no plants on ancient pasture land, on lighter soils, or on clays, that appeared so little 



affected by it as those I have mentioned.

In regard to produce, therefore, the Biennial-rooted Clover is superior to the Perennial, 

 in the proportion nearly of 2 to J. As a plant for the alternate husbandry, tlie Broad- 

 leaved cultivated Clover will evidently be preferred; but for permanent pasture, the cow clover, 

 (TrifoUum mediumj, must of necessity have the preference. The quantity of nutritive matter 

 contained in the herbage of the Broad4eaved Clover is somewhat neater than in the herba*^e of 

 the Perennial Red Clover, proportionally, according to my expenments, as 10 to 9. The con- 

 stituent parts of the nutritive matters of the plants are nearly alike, only the Broad-leaved Clover 

 contains nearly three per cent, more of the hitter extractive and saline matters than are contained 

 in an equal weight of the Perennial Red Clover. This species likewise contains much less super- 

 fluous moisture than the former, and is in consequence more quickly and safely converted 

 into hay ; for it is evident the difficulty of making good hay, is in direct proportion to the quan- 

 tity of superfluous moisture any herbage may contain, lie comparative fitness of the diflferent 

 grasses for making into hay, which have already come under observation, with those tliat 

 follow, may therefore he ascertained hy the statements which are given of the loss of weight 

 which each species sustains in drying at the different stages of growth . 



The value of the Red Perennial Clover has been disputed ; but it seems probable that any
