constipated animals, nothing equals a ten-grain dose of calomel, followed the next day with a four or six-ounce dose of Epsom salts (sulphate of magnesia), and as sheep are reluctant to eat any tonics in their feed, we are compelled to pour their medicine down them. Mix together 4 ounces each of the tincture of gentian, golden seal, ginger and iron, and give a tablespoonful twice a day in a half pint of water. But always give the calomel, as it will clean out the liver of a sheep as no other known agent will. The symptoms are much the same as in cattle. Begin treatment early or success will not follow. =KIDNEY WORMS.=--The hog is mostly affected with these worms, although they have been found in the dog also. Death does not, as a rule, follow the infestation unless in an aggravated form. Obviously there is no remedy. [Illustration: KIDNEY WORMS IN THE HOG While worms are occasionally found in the kidneys, they do not frequently cause disease or death.] =KNEE SPRUNG.=--A condition in which the knees bend forward as the result of contraction of tendons located along the back of the leg. In aggravated cases the tendons should be cut. If this is to be done only a skilled surgeon should be allowed to perform the operation. =LAMINITIS.=--See Founder. =LICE.=--Farm animals, especially those housed in stables more or less infested with insects and vermin, are commonly troubled with lice. Animals in good health resist the insects, but those already in a non-thrifty condition do not fare so well. Lice cause a good deal of annoyance to farm stock, inasmuch as they bite the skin, suck out blood, and thus cause considerable irritation. Lice can be seen with the naked eye. Infestation, as a rule, takes place in filthy quarters, and the best means of disinfecting such places is by the use of a spray of kerosene. One of the best means of applying this to hogs consists in rubbing posts, which are constantly smeared with kerosene. In this way the hogs are induced to treat themselves. Infected hogs may also be treated by pouring the kerosene directly over the infested parts, like the neck, shoulder and back. Dipping tanks made of cement or wood are frequently located in the run-yards, in which is placed some disinfectant fluid. Hogs use these small tanks as wallows, and in this way they disinfect themselves.
