Stove in Shaving Mug.
The newest shaving mug is equipped with a little alcohol lamp. So little water is required that it takes but a short time to heat it to the boiling temperature. The invention is one that will be appreciated by traveling men especially, as the mug is not much larger than the ordinary kind, and is, of course, much easier to carry about than shaving outfits. In fact, it seems odd that the invention was not thought of before. The interior of the cup is of a substance not injured by heat, and the lamp is lighted from the bottom. Hot water may thus be obtained at any time in a few seconds.
