66 BOARD OF AGRICULTURE. [Jan. 



when taken in season, and followed for two or three nights, 

 I have never had any trouble in destroying them. Sulphur 

 is a dangerous article to use, as you all know. The fumes 

 of sulphur are fatal to all forms of life. I have used a por- 

 celain dish, holding perhaps two quarts. I take a paper of 

 the flour of sulphur, put it into that dish to the depth of 

 perhaps an inch or an inch and a quarter, place it over the 

 blaze of a lamp and boil as you would boil sugar ; and so long 

 as you keep a supply of water in the kettle there is no more 

 danger in boiling it than there is in boiling so much water ; 

 but if you allow the water to evaporate and burn the dregs 

 which will remain in the bottom of the kettle, you will 

 destro}^ all the foliage in the house. Many who have tried 

 it have met with mishaps in consequence of being careless. 

 Or, if you attempt to boil it in a dish and do not take the 

 proper precautions to prevent the flame from reaching it, the 

 sulphur will ignite, and then you get fumes instead of vapor. 

 But if care is taken in using it there is no more danger 

 than in fumigating with tobacco, and it is entirely efiectual 

 in destroying the red spider and mildew. 



Question. Would not that method be more successful in 

 killing poultry lice than anything else that could be em- 

 ployed ? 



Mr. Hawkins. The best way is to burn the sulphur, but 

 you must first drive out the hens. 



Mr. Wood. It is a practice among greenhouse people, 

 when they have an opportunity to get their plants all out, 

 to burn sulphur ; then they get the fumes, which are fatal 

 to all kinds of life, animal or plant. The object of using 

 the vapor instead of the fumes is that we can use it where 

 our plants are, and use it at all seasons of the jeav to com- 

 bat two of the worst enemies that appear in our green- 

 houses under glass ; that is, mildew and the red spider. 



Secretary Sessions. The next question is, " Is there any 

 remedy for the cabbage worm?" I would like to call on 

 Dr. Cragin. 



Dr. Cragin. My experience with the cabbage worm has 

 been very limited. Whenever I have been called into contact 

 with it, I have used black hellebore, pulverized. I use it 

 also for the currant worm. I believe it is far more safe than
