Mr. J. T. Saltau, Little Efford, Plymouth, has forwarded us an ingenious, inexpensive, and useful contrivance which he employs for lessening the stream of water flowing from a watering-pot, as is often necessary when watering small plants, cuttings, etc. The usual way of securing the end in view is by partly blocking the orifice by the finger. Mr. Saltau procures a cork, and burns a hole through its centre by means of a hot iron, and then inserts a portion of a goose-quill which is slightly longer than the cork itself. The cork tapers so that it will suit almost any can. We think our readers may find the contrivance of use, and one that anybody can easily manufacture for himself. - Gardeners' Chronicle.
