a. Visit every farm in his district and leave appropriate writ¬ 
ten instructions. 
b. If hog cholera is found on the farm, specific directions 
should be given to confine the hogs, move the apparently well ones 
to clean pens, and at once administer the serum-alone treatment. 
The remaining hogs should be destroyed and their carcasses burned, 
or buried deep after covering each carcass with a bushel of lime. 
c. Orders should be given to clean the infected pens, burn the 
litter, remove two inches of the surface soil, whitewash the fences 
and hog houses, disinfect the feed troughs, and everything that 
may have become contaminated. A reliable and cheap disinfectant 
is pure crystals of carbolic acid, melted by heat and mixed with 
water in the proportion of six ounces carbolic acid to one gallon of 
water. For sprinkling on the floors, manure, bedding and hard 
ground where the surface soil cannot be removed, chlorinated lime 
(one pound of chloride of lime dissolved in three gallons of water) 
will be satisfactory. Corrosive sublimate (bichloride of mercury) in 
the proportion of i to 1,000 is prepared by dissolving one ounce of 
corrosive sublimate in eight gallons of water. This drug is very 
poisonous and must be handled with care. Formalin is very useful, 
especially in closed buildings and is made in five per cent solution 
by mixing one pint of 40% formalin with a gallon of water. 
d. Magpies, pigeons, buzzards, stray dogs or other animals 
that make the rounds from farm to farm, should be looked after in 
a way that seems most appropriate. 
e. Quarantine signs should be placed conspicuously on hog 
pens and front gate: Quarantine—Hog Cholera—Keep Away 
From Hogs. 
f. The work of the veterinarian in charge should be to not 
only enforce necessary regulations, but he should seek the co-op¬ 
eration of the farmer by explaining to him why it is necessary to 
guard against every possible means of spreading the infection in 
the neighborhood. The central thought with the veterinarian in 
charge should not be to save the hogs for this one man, but to con¬ 
fine the disease on this one farm, and the farmer, if he is a good citi¬ 
zen, will concur, for he will realize that it is “Better to be one of a 
successful community than the successful one in a community of 
failures.” 
g. When the veterinarian visits a farm and finds the hogs 
healthy, he should investigate the food and water supply and every 
possible means of infection and advise the farmer accordingly. He 
should insist on hog pens being cleaned as often as once a week and
