which should be applied once or twice daily for a week, 

 being applied by rubbing well in with the fingers; as the 

 disease is contagious the harness, combs, brushes, etc., 

 should be disinfected as recommended for mange. Af- 

 fected animals should be given good food and tonics. 



Maggots in auimals are generally found on wounds, 

 and often on sheep that are left untagged, is really 

 induced by uncleanliness; summer time is the period 

 when the pests are to be found, hence the reason for the 

 avoidance of such operations as dehorning during the 

 summer months; as soon as fly time begins maggots, 

 which are the larvte of flies, being hatched from their 

 eggs, should be looked for. The treatment is cleanli- 

 ness, frequent tagging (cutting off the pieces of wool 

 soiled with the urine or feces) of sheep, and the occa- 

 sional application of creolin, or some other antiseptic. 



Grub in the head is a disease affecting sheep, due to the 

 sheep gadfly laying its eggs in the nostrils of the sheep, 

 which eggs eventually hatch out the larvae or grub, 

 causes sneezing and discharge of mucus from the nostrils 

 and by the irritation set up in the nasal cavities may 

 cause death. Preventive measures are the most satis- 

 factory to adopt, tarring the nostrils being as good as 

 any, for a flock, it is recommended to bore two inch 

 auger holes in a log, place salt in the bottom and smear 

 the edges with the tar, the sheep in their desire for salt 

 will in this way apply the tar themselves, further treat- 

 ment is surgical and not practicable for general flock 

 management. Sheep seem to know intuitively the result 

 of the attacks of this gadfly and will try to bury their 

 noses in the earth to avoid its attack.
