to the lungs and pleura, and germ infection may follow, 
causing a thickening of these parts, so that breathing 
becomes difficult. Spasmodie contractions will be ob- 
served in the region of the abdomen whenever the pig 
attempts to move rapidly. There is nothing so effective 
in treating this difficulty as sunshine and exercise in the 
open air and the disease is most troublesome when condi- 
tions make this treatment difficult or impossible. In 
acute cases, a few drops of kerosene placed in the pigs’ 
mouth or nostrils may remove a sufficient quantity of 
mucus slightly to prolong the life of the pig, but unless 
weather conditions make recovery possible, there is but 
little use in this treatment. This disease is also frequently 
brought on by damp bedding or drafty quarters. The 
remedy for such cases is obvious. Loss from bronchial 
pneumonia is one of the most serious obstacles to mid- 
winter farrowing, even under most favorable conditions. 
TRIMMING FEET 
The toes of older hogs frequently become so long as to 
throw too much of the weight on the rear part of the 
foot, causing a straining of the tendons and the pasterns. 
If not attended to, the pasterns may become so weak 
that they will remain permanently broken, even when 
the toes are leveled up. If the toes are not too long, a 
sharp knife or a rasp may be used. If the toes have 
““become very long, a pair of blacksmith pinchers may be 
used to take off the surplus, after which the smoothing 
is done with a knife or rasp. This operation will prolong 
the usefulness of a brood sow and is generally necessary 
in fitting older hogs for showing.
