unsanitary conditions in the pen may also be a cause. A cough, 
fever, and hurried or labored respiration are among the 
syinptoms, 
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.

large areas to shift for themselves. No prolonged feeding is 
practised in narrow limits, but from birth to maturity they 
are pastured on alfalfa, oats, corn, rape, and peanuts... . In
