Bee The Diseases of Animals 
stock-cars bring the disease to healthy animals. When 
sheep are closely confined in pens or feeding-yards the 
disease usually spreads rapidly. 
As soon as a case of scab is observed, the whole 
flock should be dipped in some solution which will de- 
stroy the parasites. Excellent remedies are the coal-tar 
products recommended for lice (p. 317). They are used 
in the strength of one part of the coal-tar preparation to 
50 or 75 parts of water. The dipping solution should be 
warmed to 110° F., and the sheep immersed for at least. 
two minutes. During cold weather sheep should be dipped 
only on warm days and when well protected from cold. 
One of the most effective dips for sheep scab, and the 
one that is probably used in the West more extensively 
than all others combined, is commonly called the “lime 
and sulfur dip.” This dip is cheap and the ingre- 
dients can be easily obtained. The greatest objection 
to it is that the lime is somewhat injurious to the wool. 
The following is the formula . 
Fresh quick-lime nar aes . . . .8 pounds, 
SUG (sae Sar Yee Be eo ae a Ap) ee Se eh 24 pounds. 
Waters: j= ‘trestle gestae ele 100 gallons. 
The lime and sulfur should be carefully weighed and pre- 
pared as follows: Slake the lime to form a thick paste, 
sift in the flowers of sulfur and stir well; put this mix- 
ture in a kettle with twenty-five or thirty gallons of 
water and boil for one hour at least; two hours is 
better. The chocolate-looking mass is allowed to settle, 
the clear liquid is drawn off and water enough is added 
to make one hundred gallons. The ooze or sediment 
should not be used in the dip.
