A FAT-TAILED SHEEP 
This breed of sheep is common in all parts of northern China. 
The large tail characteristic 
of this variety contains a very considerable amount of fat and thus the breed has been called 
the fat-tailed sheep. 
In arid regions, when food is not plentiful enough, the fat in the tail 
is drawn on to supply nourishment for the rest of the body. (Fig. 17.) 
been observed, they are invariably the 
animals that have been closely housed 
with the European hogs. This freedom 
from disease is indeed fortunate, for 
tuberculosis is one of the few diseases 
in animals which we dread, not only 
because of the effect of the disease on 
the animal itself, but because of the 
possibility of its being transmitted to 
man. 
Fewer internal parasites are common 
in the native hogs than one would ex- 
pect. A number of tapeworm cysts 
have been found in nearly every hog we 
have butchered at the college during 
the past three years, but, according to 
Prof. Howard of the Biology Depart- 
ment of the Canton Christian College, 
they are not the cysts of the tapeworm 
that is found in man. Dr. Gibson also 
reports he has not yet found the cyst of 
the human tapeworm in the native hog. 
Here again we are fortunate, and great

care should be taken not to introduce 
this parasite from other regions. 
Kidney worms and liver flukes, 
usually common in hogs, have not been 
found in the hogs of southern China. 
A skin disease in the form of a pox 
is very common. It, however, does not 
seem to be a serious disease. With the 
exception of cholera, the native hog in 
South China is, as a whole, a fairly 
healthy animal. 
YUNNAN HOGS 
In the hilly and wooded regions of 
the western provinces of Yunnan and 
Szechwan the type of hog chiefly 
raised is the bacon hog.. This type pro- 
duces a good meat for curing. Accord- 
ing to Dr. Gibson, attempts so far to 
raise this hog in Hongkong have 
shown that it cannot compete with the 
common lard hog in the efficiency of 
utilizing feed. However, if allowed to
