cause of the listlessness and general uselessness of the chairman 
and the stubbornness and selfishness of the owner and the indif¬

are Caesar’s.” 
That it is possible to maintain successful farm quarantine 
for hog cholera has been demonstrated over and over again dur¬ 
ing the past three years. Whether individual farm quarantine 
is successful or not depends largely upon the township super¬ 
visors and the individual farmers. The mere fact that individ¬ 
ual farm quarantine has not been entirely successful in many 
townships does not contradict this statement. The thing for 
the farmers of Minnesota to do is to let go of this idea of finding 
a medical cure for hog cholera and undertake an intelligent pre¬ 
vention. It is probable that a satisfactory serum for vaccination 
will be developed in the near future, but that alone will not 
solve the problem by any means or do away with the necessity 
of sanitary measures. 
The following extracts from the “ Circular of Information 
for Rocal Health Officers,” together with the “ Hog Cholera ” 
quarantine and the owners’ “ Notice ” cards, will give some in¬ 
formation concerning the present methods of dealing with this 
disease. 
When hogs begin to sicken and die during the prevalence of hog 
cholera the disease should be reported to the local health officer or 
chairman of the town board, and quarantine should be established at 
once. It is a simple matter to release quarantine, and should it be 
proven that the disease is not hog cholera, no harm has been done by 
such quarantine. 
All health officers and acting health officers are therefore instructed 
to see that suspicious outbreaks of disease among hogs are properly 
quarantined. 
The health officer should explain to the owner or keeper the nature 
and conditions of quarantine, and see that the conditions are rigidly en¬ 
forced until quarantine is released. 
Hog cholera is often spread by water in small streams and lakes, 
and for this reason hogs must not be buried near any such lake or water 
course. 
Dogs and poultry should not be allowed access to yards or pens 
where hogs are confined during the hog cholera season, and pigeons and 
crows should be shot or otherwise frightened away because of danger 
that they may spread the disease. 
The health officer or inspector should always wear overalls and over-
