TREATMENT.—Prevention is the most important. Fields or pastures that are infected with this disease should be burned every summer if possible, to destroy the germs. The animals that succumb to the disease should be buried deeply and quicklime thrown upon them, also any blood stains upon the ground should have a strong disinfectant thrown upon them. The hide of such an animal should not be used as the person removing it is likely to contract the same disease, especially if an abrasion is present on the hand, or such a hide or any portion thereof is likely to spread the infection after reaching the tannery, etc. MEDICAL TREATMENT OR SERUM TREATMENT.—This is the only thorough method of eradicating the disease, and when this disease once becomes prevalent in a locality all animals should be inoculated with vaccine. BARRENNESS. (_Failure to Breed_) CAUSE.—Wasting or Atrophy, chronic inflammation of the mucous membrane lining the organs of generation, Whites, absence or excessive secretions of the organs of generation, contraction or displacement of the womb, horns being telescoped or twisted, cysts or growths on the ovaries, in-breeding or being a twin, are the predisposing causes of Barrenness. TREATMENT.—Unsuccessful as a rule. Unless the cow is very valuable, treatment is not advisable. A careful examination, however, is recommended. If due to contraction of the neck of the womb it can be readily dilated by the use of the hand, which should be greased with Carbolated Sweet Oil before attempting to perform the operation. BLACK LEG. (_Symptomatic Anthrax—Black Quarter_) CAUSE.—Due to germs. The Bacillus of Black Leg perhaps gains entrance to the blood by wounds of the skin or the mucous membranes lining the mouth and the intestines. This disease principally affects cattle, although sheep and goats may become affected with the same disease. SYMPTOMS.—This disease affects cattle that are in good condition between the ages of six months and two years. In most cases death is very sudden, and perhaps the animal is found dead. The first symptoms are high temperatures from 104° to 108°F., loss of appetite, the animal stops chewing the cud, breathing considerably hurried, the joints of the limbs become swollen, also the chest and shoulders. All the swellings are painful on pressure and spread very rapidly over the body. The affected animals move with great difficulty and lie down frequently. If the hand is passed over the body, there is a peculiar crackling sound due to the gas developing under the skin. At the most distended portions of the swellings the skin becomes dry and the animal apparently has no sense of feeling. If the skin is punctured at this place, there will be a dark red, frothy discharge which has a very disagreeable odor. There will be a shivering of the muscles and the animal dies in convulsions.
