poison caused from the bites of these animals while they art- 

 mad. The saliva of the mouth contains the poison and this 

 is how it is caused from a bite. Every animal that they bite 

 does not go mad, but about one-fourth of the animals bitten do. 



Symptoms. — A few days after being bitten the animal 

 loses its appetite, is very restless and anxious looking ; then 

 there is increased restlessness, loud roaring at times, bunting 

 at things and pawing with the feet. Saliva drips from the 

 mouth and there is a peculiar wild look in the eyes. The 

 animal continually strains to pass manure, but very little 

 comes, and in a short time becomes paralyzed in the hind 

 quarters, falls down and death soon relieves it. If the above 

 symptoms are present, and a mad dog has been through that 

 section of the country, you may as well destroy the animal, 

 as it is dangerous to have around. 



Treatment. — If the disease has set in, destroy the animal, 

 and in going around it be very careful not to let it hook or 

 bite you. If treating the animal just after it has been bitten 

 by a mad dog, take a sharp knife and cut a piece right out of 

 the wound, then take a stick of caustic potash, or nitrate of 

 silver, and burn the wound well with it. If you have not got 

 these, burn the wound well with a red hot iron, which will 

 also kill the poison. 



5. Lumpy Jaw (Actinomycosis). 



This disease is contagious and spreads among cattle. It 

 is caused by germs known as "actinomycosis," generally af- 

 fecting the upper or lower jaws, but may affect the tongue 

 and other parts of the body. It is communicated from one 

 animal to another by the affected animals slavering on the 

 grass or over feed and other animals taking it up when eat- 

 ing or drinking. These germs pass down into the bowels, 

 where they are taken up into the blood and carried around 

 until they locate in the jaw. They may also be taken into the 

 system from the slaver getting into the wound on another 

 animal. It is thought that this disease may be carried to and 

 affect man by eating the flesh of an animal affected 'with it. 



Symptoms. — If it affects the jaw there will be a hard, 

 bony lump form opposite the roots of the teeth, either in the 

 upper or lower jaws. It gradually works in the jaw, the 

 lump grows, and in the course of time becoming so bad that 

 the teeth loosen and fall out. The animal cannot eat, falls
