 broom, briars, and thorns. The dung of the cattle also, when 

 left in heaps as it is dropped, kills the grass, and introduces 

 coarse and less palatable plants. This must be carefully beat

 is as important in grass as in arable land ; and if it is ne-

 quality of the feed. The urine of the cattle is the manure 

 which* chiefly keeps up the fertility of grass land ; and
