CLEARING OF MINES OF CAltBURETTED HYDROGEN. loo. To ths Editor of the Mining Journal. SIR.—My attention having^been casually directed to the subject of clearing mines of carburetted hydrogen, when much accumulated, a plan occurred to me, which seems to my inexperienced view likely to be effective, safe, and economical. I give the idea crudely as it has occurred, trusting that some of the experienced miners who read your valuable and widely circulated publication, may be able to turn it to practical use. The plan is to have an iron chamber,or box of thin sheet iron, made air tight, all but two apertures, one at each end—the one to he covered with wire gauze, the other closed by a pipe connected with an air cylin- der-a small fire to be placed in the chamber close to the wire gauze. The cylinder to be worked by two men with a fly-wheel, a pipe leading from the cylinder to be immersed in a reservoir of caustic lime and water, made into a puddle. The gas being drawn through the 6re by the action of the cylin- der, would burn in the chamber without communi- cating an explosion to the gas outside, while the deleterious prod uct-carbon ic acid or choke-damp -being forced into the lime, would be retained by it. To prevent the iron chamber getting too hot it might be made double, with a small space to be filled with water, and the wire gauze placed in a short piece of pipe, with two or more divisions. I am, Sir, your obedient servant, Llaneily, Oct. 15. T. H. LEIGHTON.
