changed the form arm of tile the blast furnace lie has advanced the art of smelling smelting am sm elting iron ores prodigiously towards perfection he has cheapened the elie cost of iron to all c of this most valuable of the metals I 1 in his experience as a founder he had in common with other irn masters observed that at certain periods in a blast or otherwise in the llie life of a furnace it produced more metal than at others with sound philosophic method he once blew out a furnace that lie he was working 9 at this period and examined the inside of I 1 it t to see what was its condition nt the moment of its best perform performance ince he dincov discovered ered what hall deeds of other iron masters had witnessed before him that thai ti tie the e action of the blast and the power of the heat heal had worn and enlarged tile the furnace at the top and nt at ils bottom but unlike them the n ile he connected this change of shape with the fact of the increased yield of the furnace and determined that that was the true form i in n which a furnace should be originally built we insert two extemporized cuts here made with a jack knife that will sufficiently illustrate howards improver improvement nent A ip ill the shape of the interior of the common orthodox furnace B shows flows r the inside of howard s 0 1 1 I 1 I 1 A B it was precisely four months and ten days from the dumping of the first load of stone for mr howard s furnace to the putting of tile the blast onto it there was no preliminary heating up of the file stack as is always done by the regular founders the masons quit work the furnace was charged and the blast clapped onto her and out came tile the iron I 1 tile the initiated will appreciate tile the great changes thus far noti noticed eed the stack is 47 feet high the base is 25 fret feet square the first 18 feet are of sandstone and also b blidt ailt square and battened on the outside ly 1 4 inches to the foot inside of the furnace is carried up perpendicularly the stone being neatly cut and fitted to a 12 f foot bot circle to receive the hearth the 29 feet above the square bottom are circular and built of firebrick the outside wall is 11 inches thick the inside lining of br brick ick 13 inches long on W and I 1 11 I 1 inches thick with 11 inches of backing sand and between the entire thickness of the circular portion of the stack is 33 inches it is around with iron this furnace thus di benses with the old fashioned hearth and basli tile inside instead of being drawn in small at the top is carried up straight and gives the gunnel head the same did diameter meter as the top of the bosh the first visible effect of this great innovation is 97 that tile the furnace is cool around the bottom and about tile the tu yeres the blast is not kept down by the conical shape customary to all other furnace interiors teri ors tile the jirld win d enters easily and passes up easily through the stock next the stock will not lodge in this furnace as in others nor will it fall irregularly and at intervals if the ehara ing is steady and the engine steady tile the stock must come down steadily the influence of this in giving uniformity to the character of the iron will be appreciated by founders the increase in the capacity of the furnace to carry burthen will also be noted by them I 1 the hearth in howards furnace is cut cir cling and

and limestone contiguous to it and with such men men as howard to 0 build and work her furnaces ohio should buy her railroad iron miles away from home instead of making it herself within her own borders the act is so irrational so wasteful that one is almost tempted to believe that the purchase in the case of this road was induced by the voluptuous desire to enjoy paris and cheaply to visit
