Another method of prevention is to plow a furrow in the pasture to give the sheep an oppor- tunity to bury their noses when the fly approaches. Hoose, husk, paper-skin, lung-worm disease. These terms are used to designate a disease of the lungs and bronchial tubes produced by two species of parasites, the thread lung-worm {Strongy- lusfilaria) and the hair lung-worm (Strongylus ovis- pulmonalis). The thread lung-worm is one-half to two inches long and is found in the bronchial tubes. The hair lung-worm is much smaller, two-thirds to one inch long and of the diameter of a hair, and is found in the air cells and lung tissue. Infested sheep do not show any signs of disease until many worms are present and extensive changes have occurred in the bronchial tubes and lungs. The most prominent symptom is a cough, which occurs in fits or spasms, leaving the victim almost suffocated. During these coughing spells the worms are ejected and scattered about, and as these discharges contain the embryos, food and water contaminated in this way become infectious. There is also a discharge from the nostrils in which the young worms and fragments of old worms can likewise be found. In the later stages, the skin is dry and harsh, whence the name paper-skin; the wool is dry and can easily be pulled out; the eyes and lips are bloodless and there is loss of flesh and gradually increasing weakness.
