of March, April, and May, it 
most prevalent in the south of China. 
In the delta region of Canton about 40% 
of the spring pigs die each year or are 
marketed because of this widespread 
disease. The farmers recognize the 
disease by the characteristic deep red 
or reddish-purple spots on the abdomen, 
gummy eyes, spotted kidneys, and in- 
flamed intestines, which are the com- 
mon symptoms in this region. It 13 
usually accompanied by a high fever. 
The Chinese have learned by experi- 
ence that there is no cure for the 
disease, and know that it is very in- 
fectious. It usually proves fatal. Ex- 
perienced veterinarians, and laboratories 
for the production of vaccine for. the 
prevention of the disease, are badly 
needed. , 
Keeping brood sows to an extreme 
old age, or until they become sterile, is 
probably the salvation of the hog in- 
dustry in China. Such sows have either

and have become immune or are highly 
resistant to the disease, for, according 
to village farmers, very seldom does a 
sow more than 3 years old get the dis- 
ease. Further study is necessary to de- 
termine the extent of this natural or 
acquired immunity. Evidently it

Canton, where cholera rages nearly 
every year, have any of the appearance ;

TUBERCULOSIS AND PARASITES 
Tuberculosis, a disease quite common 
among hogs and other livestock in 
America and Europe, gives very little 
trouble to native livestock of southern 
China. According to Dr. A. Gibson, 
who has been the Colonial Veterinarian 
of Hongkong for thirteen years, and 
who has examined the carcasses of 
thousands of hogs in the government 
slaughter house, tuberculosis in Chin- 
ese hogs is very rare; in cases that have
