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 tem- 

 perature rises as high as 107 degrees and there is lameness in 

 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. The 

 symptoms gradually get worse. The animal acts as if it had 

 severe spells of" colic, but continues looking around to wher-j 

 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 fee! it, and 

 nothing discharges except a dark red, frothy looking sub- 

 stance, which has a bad smell. If you skin the animal where 

 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 recommend 

 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 parts 

 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.
