Lice on Plants—Successful Destroyer.
A correspondent of the California Horticulturist, having exhausted all the known remedies for destroying plant lice and other minute forms of insect life which play upon plants, resorted to coal oil (kerosene) which proved a complete exterminator. He says: " I procured from a druggist an atomizer, and filling the bottle with kerosene, sprayed over a camelia to be experimented upon. It was a very dirty plant, branches and leaves covered not only with scale; but with black fungus; a very small quantity sufficed to vaporize and cover the entire plant. After the fluid had evaporated and the plant was dry, the scales were found dead, shriveled, and partly detached, and with the slightest touch fell off; the black fungus, also, which everybody knows is so tenacious on the leaf, was dried up into a, loose powder, which a shake sent to the ground.
