DISEASES OF SHEEP. 

 THEIR TREATMENT. 



The scab. This is one of the most severe scourges of our 

 flocks, and from its contagious character, there is scarcely 

 a limit to its ravages. ' Prevention is better than cure ; ' 

 therefore, every precaution should be taken against mix-

 as soon as the disease appears it should be attacked. 



The Southdown wash is a preparation of this class ; and 

 there are agents in the city for the sale of the paste, each 

 tin being labelled with instructions for use.

 preparation ; one, when the wool is on the sheep, is as 

 follows : To a demijohn of five gallons (five frascos) of 

 water, put one pint bottle of the mixture, and keep it 

 corked. Take such a tin as is generally used for filling
