BENNETT, Secretary. Acerments By Buastinc — Tamprinc.— How frequeuily do we hear of the painful fact that a poor man has lost bis life by blasting ! Why does this occur? I believe that,-in nineteen cases out of twenty, it is througb carelessness—from a waut of consideration that they are dealing with gunpowder. et the charge of powder be put into the hole, not all at once, but whilst it is being done, settle it down twice or thrice with the swabstick, and when all in, ram it well down with the same tool—not with the iron ramming-bar—and cover it tightly and firmly with a piece of dry-clay. This done, at once dip the end of the swabstick in water, or better still, into the wet sludge that has been made in the process of boring, and with it free the sides of the hole from the dust of powder which must, of necessity, have adhered to them in pouring in the charge, and which, if uot removed, will be likely, by a spark from the rammiug-har, in tamping, to convey fire to it. Well wipe out your hole with the wet swabstick, Haviug done this put in a large layer of fine, properly prepared tamping, and softly and carefully settle it down and “floor” it with the ramming-har alone— usingno hammer for the first layer. I say putin a large layer, becansé if the first layer bea small one, it will be the more liable to be forced down by the rammingbar and disturb the powder. Settle down the first layer of’ tamping in this way, and then, with impunity, the hammer may be used—taking care, at the same time, to keep the ramming-bar free from the safety-fuse. Let these little matters be attended to, and no fear of explosion in tamping nced be apprehended—all will be safe—life will uot be sacrificed. As 2 matter of conrse, proper material fur tamping should be selected. Lhave freqnently kuowu miners, when working on hard, fiery gronnd, to carry tamping from home daily to the mines with them—stoue of a soft yielding nature, and well bruised before used — bruised, coarse potsherd is good. There seems to be au idea existing very generally that tamping requires to be driven with great force with the hammer, so much so that,. as before said, the mallet is sometimes employed; but this, as has fatally been proved, is not necessary—nay, if the hole be judicionsly placed, even the hammer, generally speaking, need scarcely be used. I say fatally proved, because it is weil known that on the first layer of tampiug being hammered down explosion has taken place, the burden of the hole has becn removed, and the poor unfortunate miner has lost his life.—Joun Lean: West Briton. Fournact Luprovements.—A series of experiments, says the London Quarterly Journal of Science, has recently been carried out in London, in proving the utility of a new form of furnace, invented by Mr. T. J. Lehigh. This furnace is applicable for puddling, steel-making or other purposes for which an intense heat is required, and is adapted for burning fine or refuse coal, ‘‘which is instantaneously converted into gas as it is fed in,” (?) a perfect combustion and intense heat being obtained. The crop ends of steel rails, placed in the furnace were reduced toa perfectly fluid state in twenty-five miuutes. Wrought iron was also readily melted. Neither the peculiar construction of the furnace, nor the manner of feeding the fuel, is giver. The coal is probably-used in a pulverized condition; ‘‘the instantaneous conversion of tbe coal into gas,” is hardly presnmable. Professor P. Turner, a gentleman of much experience in such matters, according tothe authority already quoted, has writteu very favorably of a modification in the blastfurnace recently introduced by a Prussian iron manager. In this invention the walls of the hearth are carried to the bottom on all sides, so that there is no opening in the frout—no tymp aud no dam, The scoriais discharged through a scoria-outlet about six inches below the twyers, The advantages claimed are that vacillatious of the slag on the hearth is prevented; as there is no forebearth, there is no repairs of it—which is considered equal to a saving of at least twenty days in each year; there are no interruptions, and the furnace does not cool; the number of charges can be greater, and the number of hands lessened, while the work is much easier for all employed. Iowa, alone, of all the States, is ont of debt,’ She does not owe a dollar. This happy condition of freedom from debt is due to tho wise and economical administration which the people of Lowahave been able to give them. It is, indeed, an enyiable situation, which other States groaning under debt and taxation may look at with an admiring eye. ’
