years of age. It, too, is the result of a germ. Cattle grazing, 
on low-lying lands are more liable to be affected. 
Symptoms. — About three days after the germs get into 
the system the animal becomes dull and feverish, the tern 
perature rises as high as 107 degrees and there is lameness ii) 
some of the legs, generally in one of the front ones. This is 
caused from a swelling which usually forms just behind the 
front leg, but may be in any other part of the body. Tht- 
symptoms gradually get worse. The animal acts as if it had 
severe spells of colic, but continues looking around to where 
the swelling is, breathes heavy, becomes very weak and soon 
dies. The swelling grows very fast, and when you rub your 
hand over it, makes a crackling noise as if it contained air 
If you cut into the swelling the animal does not feel it, and 
nothing discharges except a dark red, frothy looking sub- 
stance, which has a bad smell. If you skin the animal whert- 
the swelling is, there are dark brown, dark red and yellow 
colored patches, and the parts around where the swelling is 
are soft and easily torn. 
Treatment. — There is no treatment for this disease, only 
to remove the sound animals, destroy and burn the affected 
ones, and drain and break up the pasture. We recornmcnd 
the use of black leg vaccine* as a preventative, full directions 
for the use of which appear on the package. 
8. Texas Fever. 
This disease affects cattle all through the southern part.- 
of the states, and is caused by germs getting into the blood. 
These are carried from one animal to another by cattle ticks. 
Symptoms. — At first there is dullness, loss of appetite, 
and the patient leaves the herd and stands or lies down alone. 
The temperature at this stage is from 105 to 107 degrees, and 
remains so or nearly so all through the disease. The bowels 
are constipated, and anything passed is covered with bile. 
Near the end of the disease the urine or water is of a dark 
red color. The pulse and breathing are both quickened. The 
animal becomes very stupid, lies down most of the time, and 
in a few days death relieves it. In some cases they die in 
three days, while in others they live for several weeks, and if 
an animal does recover it takes it a long time to do so.
