clofe funny weather in the fummcr fcafon, aic highly prcjudicJul in deftroying the 

 clover plant.* 



When the clovers are kept in the ftate of herbage more than one year, they arc 

 not by any means fo proper for fowing wheat after as in other cafes : it is the 

 full fmothering crops that afford the mofl fuitable preparation for this fort of 

 grain. 



Befides the common red or broad clover, there are other kinds ufed in cultiva 

 tion ; as the White or Dutch clover, and Cow Grafs. Thefe, from their bein/ 

 more frequently employed in the laying down of lands for the purpofe of perma 

 nent grafs, have been defcribed above. The firfl affords a fine delicate herbage, 

 which is very agreeable to moft forts of flock. In the fecond it is morecoarfe and 

 abundant but ftill lefs fo than the common clover ; and the plant has the advan 

 tage of growing better, and of being more lafting in the poorer forts of clayey 

 foils. 



Trefoil.^ This, as being an ufeful plant in permanent grafs lands, has been already 

 noticed ; but its properties as an artificial grafs may be defcribed in this place. It 

 is of much lefs growth than common clover, and much flenderer in the ftem ; but 

 notwithstanding it is fometimes fown with grain crops in the manner of that crop, 

 the proportion of feed made ufe of is about three pottles when cleaned from the 

 hulks, but in the contrary (rate two bufhels are moftly employed. Thefe may 

 however be varied according to the circumftances of the land. 



Some fuppofe it an advantageous practice, efpecially where large flocks of cattle 

 are kept, to fow it with oats, or among the wheat crops in the fpring when they 

 are to be fucceeded by grain in the following feafon, as by this means good feed 

 is produced in the ftubbles for flock in the latter part of the fummerand in autumn ; 

 and at the fame time they are left free for tillage in the fpring. The feed is capa 

 ble of being procured at a cheap rate.* 



It is faid alfo to afford excellent paflurage for cattle, but to be more particularly 

 calculated for fheep, either when in mixture with clover or alone, as it is not fo 

 liable to hurt them by blowing or having as that grafs. In the latter cafe it is of vaft 

 importance in the fupport of fheep, from its being more early than clover, and 

 coming well in after the confumption of the turnip and rye crops before the clovers
