INJURIOUS INSECTS. 365 



feeble. A salve made by mixing kerosene and lard or kerosene 

 and sulphur is an excellent specific against these pests. In case 

 of poultry, it should be rubbed on the roost poles and on various 

 parts of the body of the fowl. On cattle or larger animals it 

 should be rubbed on the bodies where the lice are thickest. A 

 decoction made by steeping tobacco steins will quickly kill lice 

 on any animal if the latter is washed with it. In winter this 

 is troublesome to apply. Ticks on sheep can be destroyed by 

 dipping in tobacco water. I have killed sheep ticks by smoking 

 with tobacco, making use of a common bee smoker. Long-wool 

 sheep are most affected. It is quite easy to part the long coat 

 and apply the poisonous fumes. 



Pyrethrum is excellent to destroy lice and mites on our do- 

 mestic animals. In close buildings it may be blown into the 

 rooms containing the affected animals, or it may be rubbed on 

 the skin between the hairs or feathers. 



Space forbids further mention of our insect enemies. With 

 the hints already given, the wise, thoughtful man may be able 

 to treat others not mentioned. 



For those eating foliage which is not to be fed to animals, 

 like that of the potato and our fruit and shade trees, use the 

 arsenites. On cabbage and currants, where these virulent poisons 

 are not safe, use pyrethrum. For the sucking insects, like 

 plant lice or bugs, the kerosene and milk will prove effectual. 

 Kerosene and carbolic acid are excellent to repel insects and so 

 prevent egg-laying, as suggested in case of the apple-tree and 

 peach-tree borers. Bisulphide of carbon is a most excellent 

 insecticide when the insects can be confined in a close box, like 

 grain weevils, etc. We must remember, however, that the va- 

 pors are very explosive.
