the 'best and safest remedy. His directions are to take 1 pound avoir- 

 dupois of pure bluestone, powder it fine, and dissolve in 9 1 / gallons 

 of warm water. It is better to first dissolve the bluestone in 2 to 4 

 bottlefuls of boiling water, then add the remaining quantity in cold 

 water, and mix thoroughly. This solution is given in the follow- 

 ing-sized doses: 



months old . . . % ounce. 



months old l 1 /^ ounces. 



months old 2 1 /a ounces. 



months old 3 ounces. 



months old S 1 /^ ounces. 



In making up the solution only clear blue crystals of blue- 

 stone should be used. Bluestone with white patches or crusts should 

 be rejected. It is especially important that the bluestone and water 

 be accurately weighed and measured, and that the size of the dose 

 be graduated according to the age of the sheep. 



Gasoline is one of the most popular remedies for stomach worms 

 which has been used in this country and has the particular ad- 

 vantage of being readily obtained. It is important to repeat the dose 

 if the gasoline treatment is employed, and it is usual to administer 

 the treatment on three successive days, as follows: 



The evening before the first treatment is to be given the animals 

 are shut up without feed or water and are dosed about 10 o'clock the 

 next morning. Three hours later they are allowed feed and water, 

 and at nig;ht they are again shut up without feed or water. The 

 next morning the second dose is given, and the third morning the 

 third dose, the treatment before and after dosing being the same in 

 each case. 



The sizes of the doses are as follows: 



Lambs *4 ounce. 



Sheep % ounce. 



Calves */% ounce. 



Yearling steers 1 ounce. 



The dose for each animal is measured and mixed separately in 

 linseed oil, milk, or flaxseed tea, and administered by means of a 

 bottle or drenching tube. Gasoline should not be given in water. 



Many other remedies in addition to those mentioned here have 

 been used, in the treatment of stomach-worm disease with more or 

 less success. Several of the coal-tar dips on the market are recom- 

 mended by the manufacturers for the treatment of worms, and the 

 action of some of them is much the same as that of coal-tar creosote. 



"Whatever remedy is used, it is wise to test it on two or three 

 animals before the entire flock is dosed. 



Fluid Extract of Kamale, in doses of 1 drachm per 50 pounds of 

 lamb administered in glycerine with 2 or 3 ounces of water, has been 

 recommended. (B. A. I. "Animal Parasites of Sheep," Circ. S. 93
