as well as feed. The following morning give the gasoline in milk, linseed 

 oil, or flaxseed tea, mixing the dose for each animal according to age as 

 follows : 



Lambs 2 drams (8 cc). 



Sheep. 4 drams (16 cc). 



Calves 4 drams (16 CO.). 



Yearling cattle 1 oz. (32 cc). 



Three hours later allow feed and water. At night again confine the 

 animals without feed and water. The next morning give the second 

 dose, the third morning the third dose, the treatment before and after 

 dosing being the same in each case. GasoHne should not be given in 

 water, nor should it be given soon after the animals have taken water. 



Coal-tar creosote may be given in solution of one per cent, strength. 

 The solution is made by shaking together one ounce of coal-tar creosote 

 and ninety-nine ounces (6 pints and 3 ounces) of water. The doses of 

 this as recommended by Stiles are as follows: 



Lambs 4 to 12 months old 2 to 4 ounces 



Yearling sheep and above 3 to 5 ounces 



Calves 3 to 8 months old 5 to 10 ounces 



Yearling' steers 1 pint 



Two-year-olds and above 1 quart 



If a good quahty of coal-tar creosote is used, good results may be 

 obtained from a single dose of this one per cent, solution. 



Other remedies, such as lysol and arsenic, have been recommended 

 by various authors, but probably the most effectual will come within 

 those which have been particularly mentioned. 



The treatment should be administered to the entire herd, since an- 

 imals which may be but lightly infested will remain a source of reinfec- 

 tion to others. 



The general condition of the animals should be built up and main- 

 tained by a generous supply of nourishing food and they should receive 

 a plentiful supply of salt.
