A correspondent of the Country Gentleman relates that, several years ago, he effectually expelled the bark louse from his apple trees by placing small pieces of whale oil soap in the forks of the limbs of the trees in a way that it will be retained in place until dissolved by rain and carried over the bark. There is nothing new about this, except the method of application. Whale oil and other soaps, for its removal, are almost coeval with the appearance of the bark louse itself. Any alkaline substance, of sufficient strength, will destroy it; but with large trees, badly infested, no application of the kind is scarcely practicable. The best remedy, we know of, is to keep the trees in a robust, healthy, growing condition.
Those who are troubled with this pest will welcome the following from the Gardener's Monthly: " In the class of scented flowers, the Heliotrope, the Mignonette and the Sweet Alyssum command a prominent place. The last is liable to suffer much from the cabbage-fly. A syringing with water, in which a few drops of coal oil has been spread, soon settles his business. There is a variegated Sweet Alyssum, which is very pretty."
A correspondent of the Gardener's Chronicle says that he has found gas-tar water, diluted to the color of weak coffee, to be the best preventive to the ravages of slugs on all garden crops, and also an excellent manure, applying it by night, from an ordinary watering pot, and half the slugs will be killed, and the rest much weakened. A second dose, after the interval of a week, is generally sufficient to banish them altogether.

I have never found anything that will compare in efficacy for pi-eventing black excrescences on the plum tree to a strong solution of chloride of lime, applied to the wounds made by their removal. I have tried this remedy two years, and in no instance has it failed to prevent the fungus wood from bunting out again from the wound. A trial was made this year on about fifty young tree?, from a portion of which the knots were cut off early in summer, and no application made to the wound; to a second portion strong lime was applied; and to a third, chloride of lime. In numerous instances the excrescence burst out again in the two first cases, in the latter none. Salt has been strongly recommended, but the superiority of the chloride was very decided.
