mealy bug, and finds a threepenny tin of Keating' s powder offered as a 

 remedy. But if one goes to a reliable nurseryman or seedsman and 

 asks for advice on horticultural matters he generally obtains the informa- 

 tion he wants. I am glad to say that strong efforts are being made to 

 alter the law relating to the sale of poisons for horticultural purposes, 

 and it is to be hoped that at no very distant date it will be possible to 

 obtain nicotine from any respectable nurseryman or seedsman ; but as 

 the law now stands it can only be purchased from the chemist or from 

 the manufacturer. 



I will now briefly touch upon a few cases where the use of nicotine 

 is indicated, and has been successfully used. In all cases of plants 

 attacked by aphides, woolly aphis or American blight, scale, mealy bug, 

 red spider. A great many nurserymen and fruit growers complain 

 that they cannot effectively deal with red spider, but if all vines &c. 

 were properly fumigated with nicotine, the insects would be destroyed. 

 In nearly all cases in which plants and vines are affected with blight in 

 hot or cold houses or out of doors, nicotine should be used either by 

 fumigating or by direct spraying. I think that in the foregoing remarks 

 I have said enough to show you that nicotine is of great use in horticulture, 

 and that it is proving itself to be an insecticide of great value.
