 wool. It cleans and dries the offensive perspiration 

 of the sheep, and destroys the smell caused by the dew 

 in the mornings, or by damp hot weather. In most 

 situations, one dressing in July and another in August 

 will suffice ; but as the expense is trifling, and the 

 process simple, it may be better to apply it more fre- 

 quently, especially in low and damp situations." The 

 liquid is applied only in dry weather. A teapot, or 

 any vessel of a similar form, is filled with it, and one 

 person pours it on the wool, while another rubs the 

 fleece to facilitate the passage of the fluid. At the 

 times of using the solution, all superfluous wool ought 

 to be shorn from the buttocks, but not too closely. 



When the insects are very troublesome, drive the 

 sheep if possible to higher ground, Examine carefully 

 all wounds and ulcers, however trifling, and dress them 

 with any simple ointment containing a small propor- 

 tion of sulphur, mercury, or white-lead. Lastly, bury 

 all useless carcasses as speedily as possible, by which 

 means you will keep down the number of the flies.
