and by giving them feeds having a laxative effect, such as slops to 
which flaxseed meal is added. Increasing the quantity of green 
feed in the ration also helps to restore normal functioning. Young 
succulent alfalfa is especially good. In severe cases a dose of 
Glaubers or Epsom salts should be administered at the rate of 
1 ounce to every 100 pounds of hog. 
HEAT PROSTRATION. 
Heat prostration results when the hogs have been driven or 
hauled a considerable distance during the heat of the day. Danger 
of prostration can be lessened by keeping the animals from becoming 
unduly excited. When prostrated by heat, the hog becomes very 
short winded, shows weakness of heart action and often consider- 
able distress, and in many instances develops convulsions resulting 
in death. This condition may be lessened or prevented ordinarily 
by pouring water on the face and feet of the animal. The best 
method probably is by use of a sprinkler, keeping the water contin- 
uously running over the head and face and on the feet, and later on 
along the bellv. 
NODULAR SKIN DISEASE. 
Nodular skin disease, called by the native Hawaiians puu puu, can 
not really be characterized as a disease. It is an affection of young 
pigs and is brought about principally by feeding an unbalanced ra- 
tion, that is, one excessively rich in protein and therefore of a heat- 
ing nature. Contributory causes include insanitary conditions, in- 
adequate ventilation, and insufficient exercise. Animals affected 
with nodular skin disease should be given an occasional bath in 
some good disinfectant solution, such as creolin, or a 2 per cent so- 
lution of cresol compound, U. S. P., and the eruptions which have be- 
come covered with scab should be touched with tincture of iodine. 
A cooling diet which is laxative in effect is also recommended as 
a relief measure. 
VERMIN AND INTESTINAL WORMS. 
LICE. 
Hogs infested with the common hog louse (H cematopinus suis) 
present an unthrifty appearance and suffer from irritation and itch- 
ing. Lousy animals, filthy infected bedding, and insanitary quar- 
ters transmit the pest from one hog to another. Lice can be eradi- 
cated only by persistent and vigorous treatment. An efficacious 
treatment can be prepared as follows: To one-quarter pound of 
common laundry soap which has been dissolved by boiling in a little 
water, add 1 gallon of rain water. Remove the mixture to consider- 
able distance from the fire to avoid explosion and while it is still hot 
pour into it 2 gallons of kerosene (coal oil) and then stir vigorously. 
The completed creamy emulsion should be diluted for use with 8 or 
10 parts of warm rain water. A stiff brush or a swab of cotton 
should be used to cover every part of the animals body with the 
solution. 6 Large numbers of affected animals can effectively be 
treated if they are immersed in a medicated liquid in a dipping vat. 
6 When hogs are treated with crude petroleum, they should be provided with plenty of 
shade and water to prevent skin scalding.
