Altogether attempts at immunizing the equine population generally, are not hopeful where it is dense, where they must be kept stabled, where the climate is moist and where glanders is deadly, or tends to persist in the chronic form for years in the same animal. Considering the prevalence of the disease in a mild form on many of the western breeding ranches it is well to test all horses arriving from the west. The same applies to solipeds imported from abroad. TREATMENT OF ANIMALS. In the majority of the states the treatment of a glandered horse is prohibited by statute. Yet without providing definite machinery for the administration of the law, and without indemnities for horses disposed of, such laws are largely inoperative. On the other hand treatment is quite successful on the pastures of our dry table lands and mountains. It can, however, be sanctioned only when careful segregation and disinfection are provided for. Acute cases of glanders are hopeless in any region, but chronic cases and especially such as have the lesions confined to the skin are much more hopeful. The unbroken nodules may be injected with carbolic acid solution (1:200), or permanganate of potash (1:60). The open sores on the skin may be treated with the same solutions, with mercuric chloride (1:2000 to 1:5000), with iodized phenol, with cupric sulphate (saturated solution), or with chloride of zinc. A primary nodule may be excised and the sore treated with antiseptics. When the lesions are very extensive the less poisonous agents should be made use of, or tincture of iodine may be substituted. The nose lesions may be treated by the weaker solutions of iodine or of iodized phenol. Benefit also comes from a course of tonics the most successful of which have been arseniate of strychnia, binodide of copper, sulphate of copper, nitrate of baryta and sulphate of iron. The sulphites, bisulphites and hyposulphites and phenic acid are desirable adjuncts. An open air life at pasture is the ideal condition. Otherwise thorough ventilation, sunshine, moderate exercise and nourishing easily digestible food including grain are very important.
