DISEASES AND TREATMENT OF SHEEP. 325 



you can watch their dropping-s, and if it works on any of them 

 as it generally does, you cannot miss it, for there will be a bunch 

 of worm as large as your two hands come away. If it should 

 not act on the sheep, starve it again for twelve hours and 

 repeat the dose, and if it is a large sheep, give a teaspoonful and 

 a half of the oil of male shield fern. Keep this treatment up until 

 the worm has passed away. Watch the other sheep to see if any 

 ■of them become affected. The dose for a small lamb is : 



Oil of Male Shield Fern | dram or ^ teaspoonful. 



Raw Linseed Oil J teacupf ul. 



Note. — This disease affects sheep and lambs far more than 



stockowners have any idea of. Often these pieces of white, flat 



worm are seen coming away with the manure, without considering 



the danger the flock of sheep are exposed to; they allow it to run 



on, not treated, until a few lambs or sheep die, then treatment is 



given to the balance after there is a heavy loss ; so you see the 



importance of watching things like this. A trifling cost and a 



little trouble will often save heavy losses in your flock. 



FLUKE DISEASE IN SHEEP. 

 This is a disease of the liver and is very common in England, 

 but not very common in this country, not so much so as it is in 

 the cattle of this country, This disease is fully described in 

 connection with fluke disease in cattle, for the causes, symptoms 

 and treatment are the same. You will find a thorough explana- 

 tion given there. 



GRUB IN THE HEAD OF SHEEP. 



This is a common disease in some localities, especially if the 

 sheep are pasturing on low-lying swampy lands where there are 

 pools of stagnant water. 



Causes. — The way this disease spreads is by allowing a sheep 

 that has died of grub in the head to lie and be eaten by dogs of 

 the neighborhood, and when they are going across pasture fields 

 they leave their droppings, which contain the grub, in the pasture. 

 The grub, being still alive, crawls onto the grass, and the sheep, 

 while eating the grass, takes the grub into the stomach, 

 and in this way it gets into the blood along with the nourishment 

 and passes around in it until it comes m contact with the brain, 

 where it settles itself in the upper side of it as near the 

 centre as it can lodge. 



Symptoms. — The symptoms are very peculiar. The sheep 

 Lholds its head to one side and a little higher than natural, and for
