 STone. In 3 to 5 days all the fibrous tissue must be rem ved. Healing 

 may be hastened by sewing up the cavity and keeping it open for several 

 days at its lowest point to allow pus to drain out. 



TEXAS FEVER 



{Piroplasmosis) 



This disease is known by the names of red water, texas plague, 

 splenic fever, spanish fever, murrain, etc. 



this disease is of little importance where there is no exchange of 

 cattle between the north and the south, however where northern cattle 

 go south or tick infected cattle go north it becomes quite an important 

 disease in many cases. The boundary line of Texas fever begins at Nor- 

 folk, Va., runs southwest to the northern boundary of Georgia, thence 

 north to the center of Tennessee, then west to the Mississippi river then 

 north to the Missouri-Arkansas line. Then it follows the Oklahoma line 

 to Medford and goes southwest to the old Mexico line leaving the west 

 third of Texas free. Then it follows the old Mexico line till the southeast 

 corner of California going one half the way up to the Arizona line 

 thence west to Watsonville, California. The tick is unable to live through 

 the freezing weather it must undergo north of this line, hence the malady 

 is checked with cold weather north of such a line. 



Cattle coming from the south are very likely to carry the ticks into 

 northern pastures unless they are dipped in vats containing dip water of 

 sufficient strengtli to kill the ticks. Just how the disease is spread can 

 not be understood unless we examine the life history of the cattle tick. 



The eggs of the tick are laid on the ground hatching into a six legged 

 active tick resembling a beetle in appearance. The time necessary for 

 such an egg to hatch va,ries from 13 to 90 days depending on the temper- 

 ature at this stage the little fellow is visible to the naked eye and appar- 

 ently get no larger till they attach themselves to cattle. The skin on the 

 inner portions of the thighs. The base of the udder and the sheath are 

 the places preferred by the tick to attach themselves to cattle, however 

 they can often be found on most any portion of the surface of the body 

 of cattle especially along the back and on the neck. After the ticks
