DISEASES OF SHEEP. 

 THEIK TREATMENT. 



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

 flocks, and from its contagious character, there is scarcely 

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

 therefore, every precaution should be taken against mix-

 disease, and should, therefore, be carefully avoided. Salt 

 as a purifier — rock-salt — should be disposed in the ' cor-

 to it.

 effectual than preparations of tobacco and sulphur ; and 

 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. 



Demarchi's preparation of tobacco and sulphurous gas 

 I have found efficient and convenient. It is sold at 

 Demarchi's estabhshment in the CaUe de la Defensa, in 

 pint bottles. I have adopted two modes of using this 

 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 filHng
