GRUB IN THE HEAD. 



This disease is one of the most serious the sheep owner has to 

 deal with, and one that needs close attention on the part of the 

 farmer. 



Causes. It is caused by the egg of the gadfly (Oestrus ovis) 

 being deposited in the nostrils of the sheep during the summer 

 months. From the eggs hatch maggots, which find their way up 

 into the chambers (sinuses) of the head, causing much pain. 

 Each larva (grub) is supplied with a pair of hooks on its head, 

 by which it attaches itself to the lining membrane- of the cavity 

 v. here it is lodged. It remains there nearly a year, when it falls 

 to and buries itself in the soft ground, and in from thirty to forty 

 days it hatches out into a gadfly.
