are similar to those of cholera. As a rule, the lungs and pleural membrane are 

 inflamed, but the button-like ulcers on the lining membrane of the intestines and 

 stomach,' which are characteristic of cholera, are absent. The lining membrane 

 of the stomach and intestines is commonly inflamed, and sometimes ulcers are 

 present, but the ulcers differ from those of cholera, being more hollowed out and 

 less button-like in appearance. 



The germs which cause swine plague are more easily destroyed and are less 

 readily carried from one farm to another than those of cholera. Up to the present, 

 medicinal treatment has not been successful, and the farmer must rely upon pre- 

 ventive measures. (See under Sanitation.) This disease comes under the same 

 law as cholera. 



Bronchitis. 



Bronchitis commonly attacks young, growing pigs, and may be caused by dust, 

 lung-worms, or damp, chilly quarters. A distressing cough, especially when dis- 

 turbed from their bed, is one of the most prominent symptoms. Many of the pigs 

 become unthrifty, and, if the disease attacks very young pigs, it is likely to cause 

 death. 



Dry, comfortable quarters and nourishing feed will often pull the pigs 

 through", and care should be taken in making the pens and yards sanitary before 

 any more young pigs are put in them. 



Pneumonia. 



Pneumonia is more serious than bronchitis and frequently causes death in a 

 very short time. It often results from a severe cold, and may also be brought on 

 by over-exertion, such as being chased, or driven at too rapid a rate. Damp and 

 unsanitary conditions in the pen may also be a cause. A cough, fever, and hurried 

 or labored respiration are among the symptoms. 



About all the farmer can do is to aim to prevent the disease. If he has a case 

 to deal with, careful nursing is the main thing. Comfortable, well-ventilated 

 quarters, and a light, sloppy diet, are important. Daily doses of castor oil will 

 help keep the bowels active, and if the weather is cold the animal should be kept 

 covered with a blanket. Treatment is not very satisfactory, as it is difficult to 

 nurse a very sick pig. 



Tuberculosis. 



The following extracts are quoted from a report issued by the United States 

 Bureau of Animal Industry : 



" Reports gathered from the various meat-packing centres of the United 

 States show tuberculosis of hogs to be on the increase, and causing heavier loss to 

 raiser and packer alike than any other disease." 



" Statistics show that when there were over 56,000,000 hogs in this country 

 their value at that time was over $339,000,000. Federal inspection at the abattoirs 

 of the country show two per cent, of the hogs slaughtered to be affected with 

 tuberculosis. Reports from Europe show a far more widespread infection, that 

 runs from 5.5 to 7.5 per cent." 



" Hogs from Arkansas, Oklahoma, and Texas are remarkably free from tuber- 

 culosis, due to the methods of caring for them, or rather the lack of care. They 

 are not restricted to feed-lots, wher^ disease is commonly found, but roam over
