THE TICKS CARET FEVER.

HOW CATTLE GET TICK FEVER. 



Cattle get tick fever from being bitten by a fever 

 tick, and in no other way. They can not catch it 

 from the air, nor the feed they eat, nor the water 

 they drink. They do not get it by being near another 

 animal which has the fever. 



No other kind of tick except the cattle fever tick 

 carries this fever. The wood ticks which sometimes 

 get on children, and the ticks we find on dogs, rabbits 

 chickens, turtles, and many other animals do not 

 carry tick fever. These other kinds of ticks some- 

 times get on cattle and annoy them, but they do not 

 and can not give tick fever to the cattle. 



The fever tick carries cattle fever from a sick animal 

 to a well animal. It carries this disease much as 

 certain kinds of mosquitoes carry malaria from one 

 human being to another. 



But the ticks do not cany this fever straight from 

 a sick animal to a well one. Once a tick has gotten- 



This cow is dying with tick fever.
