California Peach-boier. the lime is slaking. This should be done in April. A killing treatment which has proved effective and safe to the tree is car- bon bisulphide, when wisely used. Mr. Ehrhorn gives these precautions:— Carbon bisulphide should not be applied when the soil is wet or just before a rain, nor just after cutting out borers and putting on lime and other preventives. Avoid putting it on the bark of the "tree. Procure a machine oiler which will hold about eight ounces of carbon bisulphide, remove the soil around the trunk of the tree about six inches wide and six inches deep, being sure to detach all soil adhering to the trunk of the tree. After this is done, fill in this space with loose soil to the level again. Now squirt the liquid a few times from one to one and one-half inches away from the bark around the tree, and cover im- mediately with six inches of soil. Borers have been killed in from twenty hours to three days; after they are found to be dead, the soil should be removed from around the trees so that any remaining fumes of bisulphide can be dissipated Strawberry Root-Borer.—The larva of another clear-winged moth (Aegeria impropria), boring into the root of strawberry.
