DISEASES OF THE EYE AND SKIN. 231 



as it is also called, destroys the wool roots, and leaves a blemish 

 where no wool will again grow, and more or less of a scar and 

 detriment to the pelt as well. A better plan is to use a rather 

 strong mixture of carbolic acid and seed oil, such as one part in 

 twenty. This kills the maggots, and spreads in a manner to cover 

 stragglers, and promotes healing. While it lasts, it is a deterrent 

 to other flies settling on the wound. 



Prevention. In fly areas it is better to anticipate those sultry 

 days when ovipositing may be expected. A fly powder properly 

 applied will give protection for some time, and may be repeated. 

 The early morning, when the fleece is dewy, is the best time to 

 apply it. At other times, a watering-pot with a fine rose may 

 be used. The fleece should be parted along the back to receive 

 the powder, and special attention given to the parts round the 

 root of the tail. The following is a suitable mixture : White 

 lead, 2 Ib. ; red lead, 1 Ib. ; sulphur, 1 J Ib. ; spirit of tar, 4 oz. 

 The two leads should be rubbed down with the tar spirit; the 

 sulphur separately treated, by passing through a fine sieve, and 

 then mixed with the leads. The mixture is a little too damp 

 for immediate use through the holes of a flour dredger, and will 

 work better for being first spread on sheets of paper for a few 

 hours. It can then be put away, and will keep indefinitely. 



SORE HEADS. 



If by neglect the sores resulting from ram fights have spread, 

 the following powder will be suitable for dusting on : Powdered 

 alum, 1 oz. ; Armenian bole, 1 oz. ; white lead, 1 oz. ; chlorinated 

 lime, 1 dram ; prepared chalk, 3 oz. Some bad cases need a cap, 

 of the nightcap pattern, to protect the head until the wound 

 has dried and become unattractive to the fly.
