"G. G.," Brooklyn, N. Y., writes: "I have been informed that tobacco stems dried and powdered, and the powder sprinkled over aphis will destroy them. I can get plenty of stems, as we use them for smoking the greenhouse. Please say if they will answer".

[Get a half dozen stems and place them near a hot plate, then with a stone or brick crush them to powder. Sprinkle it all over half a dozen aphides. If you find it effectual get a larger quantity of stems, and get powder enough to sprinkle over all the infested plants. It will work like a charm in the event of the smaller experiment proving a success. - Ed. G. M].
