A correspondent to a contemporary gives tire following description of a safety lamp, which he thinks may he of service to the mining community : —“ Take a phial bottle of the whitest glass yon can find. Insert a piece of phosphorus of the size of a pea. Pour upon the phosphorus as much boiling oil as will fill one third of the phial. Cork the phial so as to exclude all air. This is the safety lamp. When it is required, open the phial to admit the atmospheric air, immediately re-corking it. The lamp is alight, and will give at least as much light as an ordinary miner’s lantern. Whom the lamp becomes dim, merely open the phial for an instant, carefully re-stopping it, and repeat the operation when required. It is said these safety lamps last for six mouths without trimming.’’
