Bots are known to be injurious; healthy bodies are seldom troubled with parasites. The parched and innutritions grass of the summer's heat cannot support the life accustomed to artificially saved and carefully prepared food. It is the meanness of the master which dooms the slave to starvation; he begrudges the keep of the animal, therefore, he disguises the ugliness of his feeling under a pretense of giving the horse a month's freedom and its natural food! In spring, when the herbage is young, one hour night and morning might be excused; but those hours must be before the flies are up, and after these pests are asleep. In the height of summer, when the grass has perished and the ground is hard, the health soon yields to constant exposure and to unwholesome food. The flies torment the animal, and from the shed it is often driven by its companions in the field. A large portion of the accidents which horses are liable to, occur while out at grass; many an animal is released from the stable blooming and valuable; it is, at the expiration of the month, brought home looking ragged, with a huge belly, and is never fit for a day's service subsequently. If the matter is to be regarded only in a money point of view, it would have been a saving to the owner to have paid a twelvemonth's keep, rather than lose his servant, and notwithstanding, afterward have to pay for food and treatment till experience had instructed him in the inutility of expecting restoration. But when the matter is considered in a moral sense, what right has that individual who has, for his own pleasure, accustomed a life to a particular form of diet, at his will, or for his convenience, to snatch the food from the creature and drive it forth to gnaw at stalks which had shed their seeds, and to be exposed to all the variations of the season? It is no excuse to talk about there being no work to be done while the master is at the sea-side; the devotion of a life should have earned a brief support, and the gentleman whose avarice thinks otherwise has no just reason to complain of the punishment which the indulgence of his greed will probably insure. CHRONIC HEPATITIS. =Acute hepatitis= is unknown among horses in England. The late Professor Sewell thought he had witnessed one case. Other people know they have not seen a single instance of such a disease.
