great pain and distress. The sheep shakes its tail, will bite itself, 

 is very restless; or the reverse may be the case; it may stand with 

 its head down, leave the rest of the flock, and have a listless, de- 

 jected appearance; the wool at the parts attacked by maggots is 

 raised and rough. An examination of the affected sheep will re- 

 veal numbers of whitish maggots attacking the sore spots. 

 Should the animal not receive any treatment, diarrhoea sets in as 

 a complication, due to the enfeebled state of the animal's system, 

 followed by marasmus and death.

Take flowers of sulphur and benzoated lard, equal parts, 

 and apply to the sore surfaces. Oil of tar applied to the diseased 

 parts will quickly destroy the maggots and prevent fresh attacks 

 from the fly. The fleece should be cut away exposing the whole 

 surface of the sore before applying the tar. A few drops of fish 

 oil sprinkled on the fleece will protect the sheep against the fly 

 for a whole season, but owing to its very unpleasant smell and its 

 injury to the fleece, due to its lasting properties, it is not advis- 

 able to use this agent.
