LICE show unpardonable neglect of duty wherever they are suffered to exist. They crawl all over the stable-floor and the stalls, on the pastures, and a touch is sufficient to give them to other animals. They worry and trouble the poor animal constantly; and no thriftiness can be expected where they are found. If the mange ointment does not completely destroy them, as it often will, take bees-wax, tallow, and lard, in equal parts, and rub it into the hide in the most thorough manner, with the hand or a brush, two and a half pounds for a small cow, three pounds for a large one. The next day it may be washed off in soft soap, and the lice will have disappeared from the animal, but not always from the barn. Some use a wash of powdered lobelia-seeds two ounce; steeped in boiling water, and applied with a sponge. Others hang up tobacco-leaves over the stalls. This may do to keep them away; but, after the animal is covered with them, they are not so easily scared. WARBLES.--The gad-fly is very troublesome to cattle towards the end of summer. The fly alights on the back of the cow, punctures the skin, and lays her eggs under it. A tumor is now formed, varying in size, which soon bursts and leaves a small hole for the grub already hatched to breathe through. Here the insect feeds on its surroundings, and grows up to considerable size. All this time the animal is probably suffering more or less pain, and often tries to lick or rub the part affected, if possible. Farmers often press them out with the finger and thumb. The best way is to puncture the skin with a common pen-knife, and then press out the grub. They injure the hide more than most people are aware of. LOSS OF CUD is a consequence of indigestion, and is often brought on by eating too greedily of food which the cow is not used to. Loss of cud and loss of appetite are synonymous. Gentle purgatives may be given, with such as salts, ginger, and sulphur. But when a cow is surfeited, as already said, I should prefer to withhold food entirely, or for the most part, till the system can regulate itself. DISEASES OF CALVES.--The colostrum, or first milk of the cow after calving, contains medicinal qualities peculiarly adapted to cleanse the young calf, and free its bowels from the matter always existing in them at birth. This should, therefore, never be denied it. Bleeding at the navel, with which calves are sometimes seriously troubled, may generally and safely be stopped by tying a string around the cord which hangs suspended from it. But DIARRHŒA, PURGING, or SCOURS, is the most dangerous complaint with which calves are afflicted. This is caused often by neglect, or exposure to wet and cold, or insufficiency of food at one time and over-feeding at another. Stinting the calf in food or attention will often involve the loss of considerable profit on the cow for the year. When purging is once fully seated from several days’ neglect, it is often difficult to remove it.
