and I liuve witnessed tlie dangerous effects of pure clover 

 pasture on sheep, by inducing disease, and at the same 

 time the superior value of it in pastures containing a due 

 admixture of the natural grasses ; among many instances of 

 this sort, one is selected, and mentioned in the introduction 

 to these details of experiments. 



On a comparison of the nutritive matter afforded from 

 equal weights of the white and red clovers, it appears that 

 the white clover is inferior. 



The biennial red clover (trifolium pratense) affords of nu- 

 tritive matter, 2 dr. 2 qr. 

 The perennial red clover (trifolium pratense perenne) af- 

 fords of ditto, 2 dr. 2 qr. 

 The white or Dutch clover (trifolium repens) affords of 



ditto, 2 dr. 

 The brown five-leaved variety of white clover affords of 



ditto, 2 dr. 2 qr. 

 The white clover is therefore inferior to the biennial 

 broad-leaved red clover in the proportion of 5 to 4 ; and 

 inferior to the red perennial clover in the proportion of 10 to 

 9. The brown variety of white clover is equal to the bien- 

 nial red clover in the quantity of nutritive matter it contains, 

 but with respect to the quantity of herbage it is greatly 

 inferior to the white variety, or Dutch clover. 



Sir Humphry Davy has shown, that the nutritive matter 

 of the clovers contains a greater proportion of bitter ex- 

 tractive and saline matters than the proper grasses ; and 

 that when pure clover hay is to be mixed as fodder, it should 

 be with summer hay rather than after-math hay. 



Within these few years, that is, since 1834, a new forage 

 plant has been introduced into British husbandry, called 

 ti'ifolium incarnatum, or flesh-coloured clover. If sown on 

 a wheat stubble, and harrowed in, it succeeds better than 

 if the ground was ploughed. It rises early, and in some 

 instances it has answered pretty well ; but, like all other 

 plants, the first trial is always the most promising.
