carcasses of the dead cattle and remove the sound ones from the 

 pasture; drain the field and break it up is the best way to get rid 

 of the germs. Sheep are also subject to this disease and have the 

 same symptoms. 



Treatment. — There is no treatment for this disease. 



BLA"-: QUARTER. 



This is an infectious disease and is very fatal, and affects^ 

 cattle from six months to three or four years' old. It is caused 

 by germs getting" into the system. This disease is noticed mostly 

 in cattle grazing on low-lying, swampy lands. 



Symptoms. — About three days after the germs get into the 

 system the animal becomes dull and feverish, the temperature 

 rises as high as 107 degrees; there is lameness in some of the 

 legs, generally in one of the front ones, which is caused from a 

 swelling which usually forms just behind the front leg, but may be 

 in any other part of the body. The symptoms gradually get 

 worse ; the animal acts as if it had severe spells of colic, but 

 keeps looking around to where the swelling is; breathes heavy; 

 becomes very weak and soon dies. The swelling, after it i-s first 

 noticed, grows very fast, and when you rub your hand over it, 

 it makes a crackling noise as if it contained air. If you cut into 

 the swelling the animal does not feel it, and nothing comes out 

 only a dark red, frothy looking substance, which has a bad smell. 

 If vou skin the animal where the swelling is, there will be dark 

 brown, dark red and yellow colored patches, and the parts around 

 where the swelling is will be soft and easily torn. 



Treatment. — There is no treatment for this disease, only- 

 remove the sound animals, destroy and burn the affected ones, 

 and drain and break up the pasture. 



TEXAS FEVER. 



This disease affects cattle all through the southern parts of 

 the states, and is caused from germs getting into the blood. 

 The germs are carried from one animal to another by cattle ticks. 



Symptoms. — At first there is dullness, loss of appetite, and 

 the animal will leave the herd and stand or lie down alone. The 

 temperature at this stage will be up from 105 to 107 degrees, and 

 stays about that all through the disease. The bowels are con- 

 stipated, and anything that is passed is covered with bile, and 

 near the end of the disease the urine or water is of a dark red color.
