On Haven Cattle. By Richard Peters.

The clover husbandry being now, happily for the 

 parts of our country heretofore worn out and sterile, ve-

 evil, attending luxuriant clover, whether plaistered or 

 not, is immaterial; (though some have, without reason, 

 supposed a difference,) is the subjecting cattle to become 

 hoven, by too greedily feeding on this grass, when it is 

 growing, or when cut, and given to them green, while 

 it is wet with dew or rain. — Homed cattle particularly, 

 when turned in hungry, though ever so much accus-

 be turned in, till after the dew or rain is exhaled. Beasts 

 kept constantly in the field, are not in danger, in so great 

 a degree ; horses do not always escape. Swine and 

 sheep, ai-e also subject to this malady. Any succulent 

 and juicy food, if moist with rain or dew, has a capacity 

 to generate the air, which, by its expansion in the ani- 

 mal, produces hoving. — Lucerne, pea-vine, green indi-
