2377. Mode of Preparation.—Take whatever quantity of soap you wish to prepare, and dissolve it in boiling water, about one quart to a pound; in this way strain it through a fine wire or hair sieve, which takes out the dirt, prevents its stopping the valves of the engine, or the nose of the syringe; then add cold water to make it the proper strength.
2378. How to use it.—Apply it to the rose-bush with a hand engine or syringe, with as much force as practicable, and be sure that every part of the leaves is well saturated with the liquid. What falls to the ground in application, will do good in destroying the worms and enriching the soil, and from its trifling cost, it can be used with profusion.
2379. The cost.—A hogshead of 136 gallons costs forty-five cents—not quite four mills per gallon. Early in the morning, or in the evening, is the proper time to apply it to the plants.
2380. Mildew on the Gooseberry, Peach, Grape-vine, &c., is checked and entirely destroyed by a weak dressing of the solution.
