186 DESTRUCTIVE INSECTS OF VICTORIA: 



12. "Quassia Chips." — This preparation is used largely 

 in Europe and America, but in the colonies we have had 

 but little experience with it. 



13. Spirits of Turpentine. — According to Professor 

 Cooke, of Michigan, U.S., the above, if injected into the 

 nostrils with a syringe, will effectually destroy the maggot 

 of the sheep bot-fly, also maggots in the ears or any part 

 of the body. 



14. Stockholm Tar. — If placed on the nose and inside 

 the nostrils, will, according to Professor Cooke, prevent 

 the bot-fly from depositing her eggs or larva in the nose of 

 the sheep. Place Stockholm tar in the bottom of a trough 

 to the depth of one inch, and cover with salt. In this 

 way the tar gets on the nose and into the nostrils while 

 the sheep is gathering the salt. 



15. " Whale-oil " and " Whale-oil Soap." — Largely 

 used in America in the preparation of spraying material.
