Scab is produced by an itch mite, that causes itching, rubbing, pulling 

 and shedding the wool, causing a bare and scabby skin. The parasite 

 can not live for any great length of time off the skin and does not thrive 

 on any other animal. It is therefore possible to stamp out the disease 

 by killing all mites by dipping. Solutions of tobacco, lime and sulphur 

 and arsenic are effective for this purpose. The tobacco solutions have 

 preference. They may be made by taking from 20 to 25 pounds of tobacco 

 leaves and steams and soaking for one day in sufficient water to cover. 

 Then boil for an hour and draw off after six hours. Dilute to 100 gallons. 

 Add 20 pounds of sulphur and use while warm. The lime and sulphur 

 dip may be made by slacking eight pounds of lime in some water, adding 

 24 pounds of sulphur and diluting to 100 gallons. It is troublesome to 

 prepare the tobacco solution, and is about as cheap to buy the extract 

 ready for use. The lime and sulphur dip is injurious to the wool. It re- 

 quires on an average of one and one-half gallons of dip solution per head 

 for more than 25 head. The second dipping is necessary at the tenth day, 

 so that the cost for material must be reckoned at about five to seven cents 

 per head. The coal tar or creolin dips are excellent for ticks but not as 

 effective as they should b£ for scab. As far as known nearly all affected 

 sheep have been dipped, but any person knowing of such disease should 

 report the same to the State Veterinarian, Lafayette, Ind., at once, as 

 efforts will be made to complete the work before cold weather. 



BLACK LEG. 



This disease was reported from a number of places in the state. While 

 not a contagious disease in the usual sense of being spread from one 

 animal to another by coming in close contact, it is infectious, and the 

 conditions making it favorable for the attack in one may also affect sev- 

 eral. It thus happens that usually from one to ten animals become 

 affected and die suddenly. To those not familiar with the disease it does 

 cause considerable alarm. Visitations were made to a nuvuoer of farms, 

 and the following newspaper bulletin was issued upon vaccination as a 

 preventive measure: 



VACCINATION AS A PREVENTIVE OF BLACK LEG. 



While black-leg is a disease that has been known for a long time 

 and vaccination for its prevention has been practiced for several years, 

 this means is not generally known here. The disease was formerly of 

 much more frequent occurrence than at the present time, but there still 

 remain centers of infection that cause the loss of many dollars worth of 

 stock each year.
