Bell Glasses
or CLOCHES. These are used for the purpose of protecting or accelerating the growth of a plant or plants. The French Cloche is largely employed for this purpose. Ordinary Bell Glasses are exceedingly useful for propagating purposes, especially for hard-wooded plants; or for placing over subjects which require a very moist atmosphere, such as Filmy ferns, Cephalotus, &c.; or for covering half-hardy plants or rare alpines, and thus protecting them from excessive moisture. Large Bell Glasses, inverted, serve as miniature aquaria, and many small aquatics are easily grown in them.
