PARASITIC DISEASES. 161 



nized by either, and officials who have done noth- 

 ing but antagonize the rank and file of sheep 

 men are kept in localities year after year where 

 their usefulness is greatly impaired if not actually 

 lost. This is one reason why so much enmity exists 

 upon the subject of "scab. " 



When ticks are present with the scab mites, 

 the tobacco or nicotin dips are probably pref- 

 erable, for they exterminate ticks better than 

 lime-and-sulphur. These are made up in several 

 different formulae, two of which are given : 



Tobacco 30 pounds 



Sulphur 7 pounds 



Concentrated lye 3 pounds 



Water 100 gallons 



Steep the tobacco in warm water for about a 

 day, pour off the solution, and add the sulphur, 

 lye and water sufficient to make up 100 gallons. 

 Stir while using, taking the same precautions 

 to keep the dip warm as with the common lime- 

 and-sulphur dip. 



The nicotin dip is made up as follows: 



Nicotin Four-tenths of a pound 



Flowers of sulphur 16 pounds 



Water 96 gallons 



Mix the nicotin and sulphur together in a quan- 

 tity of warm water, and add to the rest of the 

 water in the dipping vat. Keep a close watch 

 on the evaporation, as it may become too strong. 



The nicotin solution found on the market con- 

 tains a statement on the package of the amount 

 of absolute nicotin, and the correct amount to 

 make up the above can easily be figured out from 

 this basis.
