or grub, (larvae of the fly) should be at once destroyed. Hides are 

 often materially injured owing to attacks of this fly during the life 

 of the animal. Four ounces of flowers of sulphur, one gill spirits 

 of tar, train oil one quart, mixed and applied along the spine once a 

 week will tend to prevent the ravages of this fly. 



EXTERNAL PARASITES (Lice) 



Lice are the common epidermic parasites of small insects which 

 infect all farm animals, including dogs and poultry. They make their 

 presence known by causing an intense itching of the skin, which induces 

 the animal to rub or scratch the parts, often to such an extent as to 

 render the parts bare and even draw blood. The lice multiply rapidly 

 and soon become general in a herd. A herd thus afi:"ected cannot thrive 

 until the little mischief-makers are all destroyed. 



TREATMENT 



The most convenient way to destroy the parasites is to place a few 

 ounces of Louse and Fly Destroyer in a common fly spray and spray 

 the animals once daily for three or four days or until relieved. This 

 is the most effective way to destroy lice or flies and is not expensive.
