A RANCHMAN'S RECOLLECTIONS 



the Bureau of Animal Industry in 1889 was the first 

 to locate the tick as the carrying cause, while Kil- 

 boune of the same bureau in 1 889-1 890, by conclu- 

 sive field experiments, suggested by Chief Salmon, 

 proved the presence of the tick to be essential in the 

 transmission of the fever. In 1891 Dr. Salmon es- 

 tablished the Texas fever quarantine line, but for 

 ten years he had been working on the theory, and 

 was probably its actual discoverer. 



The Texas fever tick is continually confused with 

 a number of other ticks, occasionally found on cattle, 

 which, so far as the transmission of Texas fever is 

 concerned, are entirely harmless, and which one of 

 the department's earliest problems was to define and 

 demonstrate as harmless. Farmers' Bulletin 569 by 

 Dr. John R. Mohler is the most comprehensive 

 pamphlet on the subject that I have read, and an 

 historical address by Dr. U. G. Houck of the 

 Federal Bureau of Animal Industry is probably the 

 best thing of its kind. 



The ear tick, while harmless as to fever, is a 

 menace at times in the northern parts of the Shinnery 

 country of Texas. Coal oil or gasoline, injected by 

 hand into the beast's ear, is the only practical remedy. 

 Ordinary cattle dips do not penetrate far enough. 

 Fever ticks claim the short-haired parts, and are 

 rarely found on the head, and never in the ears. Often 

 in winter the ear ticks will form a perfect cement in 

 a cow's ear. We keep a lookout for cows of this
