An effective way to water rose bushes, shrubs or plants is to place an old cowhorn in the earth so that the small end will be near the roots of the plant and the large end level with the surface of the ground, and fill the horn with water. The small end of the horn should be cut off at such a point that the hole will be about the size of a lead pencil. - Contributed by Chas. L. Richards, Philadelphia, Pa.
