1076 CYCLOPEDIA OF UVB STOCK AND COMPLETE STOCK DOCTOR. 



A dip in great repute in Australia, where immense tiocks are kept, is 

 the following^ 



No. 8. 10 Pounds tobacco leaves, 



10 rounds sulphur. 

 50 Gallons water. 



Boil the tobacco in the water, .-indadd the sulphur while hot. Dip the 

 sheep in the liquor, as hot as can be borne, for five minutes. 



Tjck. — The sheep tick is a dipterous insect, but with no wings devel- 

 oped. The ticks are large and live on the surface of the 

 skin and suck blood. They are plainly seen when the 

 wool is divided, or when the sheep are shorn ; then the 

 ticks will go off to the lambs, where there is more 

 wool. The treatment for them may be the same 

 as for scab. 



SHEEP TICK Lice. — Lice are sometimes found on sheep ; they 



WITH EGGS. are of the variety of bird lice, (Trichodectes), with large, 

 broad head, with biting jaws, but no sucking tube. Bird lice are usu- 

 ally very irritating. The treatment given above will apply for lice as well 

 as for scab and tick. 



II. Foot Rot. 



How to know it. — The skin at the top of the clefts of 

 the hoofs and over the heels, which is naturally smooth, 

 dry and pale, becomes red, moist, warm and rough, as 

 though chafed. Next, there is a discharge ; and ulcers 

 form, extending down to the upper portion of the inner trichodectes 

 wall of the hoof. Then the walls become disorganized, and o*" ^"^ sheep. 

 the disease penetrative, between the fleshy sole and the bottom of 

 the hoof, an offensive and purulent matter is thrown out, and the 

 whole foot becomes a mass of corruption, often filled with magg-'tts. 

 The animal early becomes lame and loses appetite, and at length dies 

 from exhaustion. If the attack is violent, and in the first cases it gene- 

 rally is, it may reappear the second and third years, but in a milder form, 

 if proper measures be taken, and this should be done at the first symp- 

 toms of lameness. 



What to do. — Cut away all the diseased parts, cleaning the knife from 

 time to time in weak carbolic acid. Prepare a tank and fill it to a depth 

 of four inches with a saturated solution of blue vitriol (sulphate of 

 copper). Keep this as hot as the sheep can bear to stand in, by occa- 

 sionally introducing a piece of hot iron. Let each sheej) stand in this for 

 ten minutes or more. Then cover the hoof with chloride of lime, and
