Disinfecting. 29 



ing. If mixed with tar, the gases generated by the com- 

 bustion of the tAvo form the most active atmospheric disin- 

 fectant now known to science. 



No. 1. Flowers of sulphur, ^ lb. 



Wood tar, 1 qt. 



Mix with tow. 



This much, burned at one or two spots, will be enough to 

 disinfect a shed one hundred feet long and twenty wide. 



Carbolic acid in its impure liquid form ia conveniently 

 applied with a brush over the doors, walls and troughs, and 

 may also be applied to the hooves of the animals. Rugs or 

 blankets may be wet with a weak solution of it and hung 

 around, to attract and destroy any disease germs floating in 

 the atmosphere. It also has the advantage of being dis- 

 agreeable to flies, which in the summer time are otherwise 

 sure to attack and annoy the sick animal. 



Chloride of lime is also a popular disinfectant, but apart 

 from it being generally highly disagreeable to animals, it is 

 not so active as those we have already mentioned. 



The value of disinfection is no longer 023en to discussion. 

 It has been shown beyond controversy that over and over 

 again such malignant maladies as the foot-and-mouth disease, 

 the cattle plague and black quarter have been stayed in their 

 ravages and prevented from extending by a free, constant 

 and wise use of these potent agents. We add formulas to 

 prepare a number of them besides those already mentioned, 

 BO that one may be obtained when another is not convenient. 



No. 2. Sulphate of iron, 2 parts. 



Sulphate of zinc, ^ I each 1 part.
