—Chicken or fowl cholera is a germ disease, and contagious. It attacks poultry of all kinds. Diarrhœa is a prominent symptom of the disease. Bad food or improper food may aggravate the trouble, but the germ introduced into the system either in food or drink, is at the bottom of it. At first the droppings will take on a whitish color. Diarrhœa will then result. The discharges will then become thin and watery, to be at times frothy and greenish in appearance. Fowls thus attacked soon lose their appetites and become stupid and take on a sickly appearance. The head drops toward the body, the eyelids fall, and the fowls stand around as if doped. Some recover, but, unless checked, the flock will be materially injured.
Of course dead fowls must be burned at once and lime and other disinfectants used to keep the disease from spreading. The well birds must be kept apart from the infected quarters. Care must be exercised that infection be not carried either by visitors or attendants from the sick to the healthy quarters. A common remedy consists of 1 part of sulphate of iron to 50 parts of water for drinking purposes. Another common remedy is to mix a tablespoonful of sulphate of iron, 2 tablespoonfuls of dried blood, and 2 tablespoonfuls of tincture of opium with a pint of water. This is given in the food in doses of 1 or 2 tablespoonfuls of this mixture three or four times a day to each sick bird.
CHOKING.
—Horses frequently choke from too rapid eating of oats, and cattle are very commonly troubled on attempting to swallow apples, turnips, or small pieces of ear corn. In either of these cases much distress is occasioned and serious danger. In treating the horse, the best treatment is to give it a little oil, after which rub the hand up and down the gullet to scatter the accumulated oats. Sometimes it is necessary to make an incision in the gullet through which the material is removed. Better have a veterinarian do this. When food lodges in the gullet of cattle, suffocation soon follows if it is serious and in the upper part of the gullet. When such objects have lodged near the stomach end there is less immediate danger. Of course the first treatment is to try to force the object down by using the hand, if at all possible. If this cannot be done a probang should be used. The probang should be very limber, so as to bend easily, and it should be used with great caution. Cattle often are killed by the accidental puncture of the gullet as the probang is pressed down toward the mouth of the stomach. Consequently no unyielding article like a broom handle or even a buggy whip should be used. If a regular probang is not available, a rope a little less than one inch in diameter can be inserted and gently worked down the gullet. Before using the rope, grease it well and make a knob at the end to be inserted. This knob can be made of cotton strings or muslin cloth.

COLIC.
—Colic is an inflammation of the bowels characterized by a spasmodic contraction of the intestinal walls. It is a very common disease in horses, and occasionally cattle and lambs are affected with it. Both the small and large intestines may be afflicted or only one of them. There are many causes, but feed and water are the controlling factors. An animal just stopped from hard work and given a large quantity of cold water, especially after eating, may be quickly troubled. And the animal hot from work, on drinking very cold water, often gets colic. Then, too, a change of food, or a change from dry feed to green food or eating some root crop when the animal is not used to it, may bring on the disease.
