M. B. Bateham says, that after two years trial of Carbolic Soap, he feels quite safe in recommending its use as the cheapest and best method yet found for the prevention of injury by the peach borer, and presumes that it will be equally as efficacious for the apple borer. His method of using is as follows: "Take a five pound can of the soap (costing only $2), and turn it into a barrel one-third full of hot water; stir it occasionally and let it stand a few hours, or over night, for the soap to dissolve; then fill up the barrel with cold water - or I sometimes use soapsuds from the kitchen for this purpose. The liquid is now fit for use. It is of a milky appearance, and pungent but not offensive odor. It is too strong for using on plants, but will not hurt the bark or wood of trees, applied with a paint brush around the base of the trees, taking care to have the liquid enter all crevices; it immediately destroys all the insect-eggs that have been deposited, and any young worms which have not penetrated further than the bark; and I believe that for some weeks at least, unless heavy rains occur, the odor prevents the moth from depositing eggs. One application in July or early in August is sufficient.
The barrel of liquid described is sufficient for a thousand trees of bearing size, and an active lad can do the work in two days".
Mr. Bateham's suggestions are valuable, and we endorse his method, but think five pounds is too much for one barrel; it had better go over two barrels. If this strong liquid, in one barrel only, comes in direct contact with any tender roots, it will surely kill them; but if dissolved a little more, then it will do the same work of destruction to eggs, with less danger to the trees.
