 dipping, etc. 



The question of extermination of tlie tick resolves 

 itself into this: It is a good thing for counties of town- 

 ships contiguous to the Government quarantine line to 

 make a fight to exterminate the tick and have the quar- 

 antine lin^ moved South of them. But to commence in 

 the center of a tick-infested State would only lead to 

 trouble bv increasing the number of outbreaks of Texas 

 fever or by completely shutting off tick-free places from 

 cattle trade with surrounding territory. I would not 

 advise local tick extermination in Alabama except to get 

 small pastures or places for acclimation purposes, and 

 such places are not absolutely necessary for the new 

 methods of acclimating Northern or foreign-bred cattle. 

 Now this does not mean that any cattle owner should 

 permit his cattle to become literally covered with ticks, 

 but instead every cattle owner can keep off the excessive 

 number of ticks and yet have a sufficient number of 

 ticks to keep his cattle immune and to permit the calves 

 to acquire immunity. No doubt excessive tick infesta- 

 tion retards the growth and development of beef cattle, 

 and also the milk-jiroducing capacity of the milch cow. 



HOW TO RECOGNIZE AND DISTINGUISH TEXAS FEVER IN 



THE LIVING ANIMAL. 



1. Learn the history of the diseased cattle. Were 

 they bred and raised in a tick-infested or a tick-free re- 

 gion? Were new ticky cattle brought into the herd, or 

 were the sick cattle put into a new pasture where ticks 

 are present, either upon cattle or in the pasture? Look 

 carefully for the small ticks upon the sick cattle. It 

 takes an inexperienced person some time to find the 

 small, young ticks. In some cases the ticks may have
