Coke, because it makes no emoke, is peculiarly adapted f or use in eition, and there is every rea-on to belkvo that, weight for weight, it ia a more economical fuel than steam coil. Tim.-, for example, in short boilers, or those in which there is not i long run to the chimney, coke will provo more economical than coal. Two excellent illustrations of this fact have conie nnder our notice. In one, a small vertical boiler, without tubes, actually evaporated nearly Dibs, of cold water per pound of coke. With coal the same boilor could, at most, have evaporated 51bs.; that is, f t*ie coal could have been lairly burnt at all, which we doubt. In the other one. the evaporation was at the rato of G.GfUbs. of water to the pound of coal, with the boiler doing precisely the same work and under similar conditions—the only change being tbntgas i:oko was used instead of coal as fuel; the evaporation was 811b. of water per pound of coke. Steam usurs ate invited to apply for a reprint of article from the Engineer, to bo obtainod at the Gas Office. .Ahswisß to Many Coiuiespondknts.— In reply to numerous enquiries from our readers corcernini; the wonderful qualities of the Great German Ilemody; St. Jacobs Oil—mentioned in our last issue—we would inform them that tho article may be obtained from our retail druggists, or by their aid. Ask for St. Jacobs Oil, and if the desler does not keep it in stock, he will hu able to procure it in a tow days from the wholesale houses. Wβ understand them is oiistin; an immcuso demand for the remedy, which is not ao very surprising when it ii considered what it is daily accomplishing in the way of relief and cures, bordering in some instances on tho miraculous.
