that the disease was only found affecting hogs which were being 
fed on uncooked kitchen refuse and garbage or on premises where 
garbage fed hogs had been introduced. 
Summing up the outbreak at Kenora, on four premises 146 
hogs were found to be affected and slaughtered and on each of 
these premises the only information obtainable as to the source 
of infection was to the effect that they had been feeding uncooked 
swill or kitchen refuse obtained from certain hotels. On two 
other premises, on which the disease was found to be in existence 
among 17 hogs, the source of infection was traceable to there 
having been introduced on to the premises hogs which had been 
obtained from one of the parties whose hogs were being fed on 
uncooked hotel swill. The hogs which were thus obtained and 
introduced being the first to show evidence of the disease and 
the history obtained was that the other hogs on the premises had 
been entirely healthy until coming into contact with the ones 
referred to. 
Hogs were inspected at 13 other premises in the Kenora dis¬ 
trict, the hogs on which, however, had not been fed uncooked 
swill or kitchen refuse and these remained entirely healthy al¬ 
though kept under close observation for a period of over three 
months. Needless to state that during this period due precautions 
were exercised to prevent any possible infection being introduced 
from other infected premises. 
Regarding the outbreaks in the districts surrounding Winni¬ 
peg, out experiences were very similar to those at Kenora. The 
disease appeared and manifested itself on premises on which the 
hogs were being fed uncooked swill or kitchen refuse and then 
spread from such centers to other premises in the same district. 
In connection with the outbreak of hog cholera at Winnipeg, 
which was of large extent and a rather serious nature, we found 
the disease to be in existence on 62 premises and it was necessary 
to slaughter 2,219 swine either diseased or close contacts with 
diseased pigs. We also visited an additional 212 premises and 
inspected thereon 2,190 pigs, which were kept under observation 
and inspected at intervals extending for a period of over three 
months.
