seed ticks then began crawling about looking for some 

 animal to which to attach themselves. At the first op- 

 portunity this was done, and they crawled upon the 

 unsuspecting beast and began to develop immediately 

 into good-sized ticks. In from fifteen to twenty days, 

 if the animal is not immune, the disease breaks out. In 

 three weeks the insect grows to adult age, drops off 

 and begins. to lay its eggs under some convenient chip 

 or piece of dung, and so the process is repeated in-

 with eight legs. The male is smaller, rather triangular 

 in shape and in color a brick-red. The male's legs are

 fever tick which should be read by every one interested 

 in the subject. 



Scabies or Mange. This is a cattle disease similar to 

 scab in sheep. The mites, however, are a . different 

 variety of the same species, and the sheep mites will 

 not attack cattle nor will cattle mites make a host of 

 sheep. The symptoms are the same in each case. The 

 constant desire to scratch, raw bleeding necks and shoul-
