Book 3 — Smoking of Lamp Overcome by Increasing Draft

While sitting in a room around a lamp, a group of workmen discussed the probable causes for the smoking of an oil lamp. By way of experiment, holes were punched in the perforated part of the burner, increasing the draft through the glass chimney. It was then possible to turn the light up much higher, without the usual deposit of smoke. As a result of this, several other troublesome lamps were soon remedied.—J. E.
