Calves sometimes suffer from CANKER IN THE MOUTH, especially at the time of teething. The gums swell, and fever sets in. Common alum or borax, dissolved in water, may be applied, and a mild purgative administered, in the shape of one or two ounce doses of Epsom salts. The diseases and complaints mentioned above are nearly all that afflict our dairy stock; and the list at least includes all the common diseases and their treatment. Some of the diseases and epidemics from which the cattle of Great Britain and other countries suffer are not known at all here, or are of so very rare occurrence as not to have attracted attention; and among these may be named pleuro-pneumonia, typhus fever, cow-pox, and various epidemics which have from time to time decimated the cattle of all Europe. To accidents of various kinds, to wounds, trouble with the eyes, and to lameness from other causes than those named, they are, indeed, more or less subject; but no work could anticipate or cover the treatment best in every case, and much must be left to the judgment of the owner. I have tried to make this chapter, which I consider one of the most important of any to the dairy farmer, of practical value to every one who owns or has the care of a cow. But, lest a want of familiarity with some of the medicines recommended for particular diseases, or the fear of the expense of procuring and keeping them on hand, should deter some one from providing himself with a good medicine-chest, I wish to remind the reader that no small portion of them are always to be found in every well-regulated household, and that the others are obtained at so little expense that no one need be without them for a single day. Let us see, for instance, how many of them are at hand. But few families are destitute of a supply of ginger, camphor, red pepper, lard, molasses, cinnamon, peppermint, starch, turpentine, tallow, bees-wax, burdock, and caraway-seed. The farmer’s wife or daughter will generally have a supply of ammonia or hartshorn.
