A correspondent inquires whether the canker worm could not be destroyed by burning sulphur under the trees? No doubt it could be, but possibly the leaves would be destroyed at the same time. Yet the question may be asked whether, as the canker worm will surely destroy all the leaves, may it not be as well to destroy the leaves your-. self and the worm with it, so as to give the earliest chance possible to a new crop of leaves?
Possibly there is a germ of utility in the suggestion, but it requires thoughtful experience to work it out properly.
