Bethlehem has a splendid system for dls- cha'rglng (he ore, tha outstanding feaura,ot which le thn twin ore bridges or conveyors, which have a span of ES0 feet and a travel ing area of a thousand times their span, permlftlnr them to convey tha ore to any desired point. Mo interesting Is tha entire -method, In deed, .that a brief unfechnlcal description would seem to be Imperative. First, the cars are run two at a time Into a cylin drical device that turna over and precipi tates ilia ore Into the pit. Here It Is picked tip by a fourteen-ton grab bttclfat a part ot the equipment of tha bridgeand car ried to a designated pllo, all the ores being kept apart. As needed It Is mechanically loaded Into eight-foot gauge electrically propelled cars and conveyed to the blast fnrpsces. Here It la dumped Into hoppers, then lotted Into the skips and carried to the top of the furnaoe by Incline and emptied on to tho top of the upper "tells," each of these processes being automatic In the old-typo furnace there was only on "belt.' the technical designation for Ihe oup-shaped receptacle Into which the or, ooke and limestone are .placed, and which, by dropplnr and revolving, empties tha same Into the furnace, consequently when the operation was In progress, there oeing no oarrier against uieir esospe, ma r IP gases, rorcea oy oomoustion, would rt ekyward as though Impelled by omnlpot force. Ant ""' What a tremendous waste ot energy this scape spelled can be readily understood when It Is stated that there are generated In a blast furnace 1(0,000 oublo feet of gas to every .ton of pig Iron produced. In the modern furnsce there are two bells, on over the other, Ths material Is first plaeed on the lop of the first bell, which revolves and drops It on to the bell below, which. Is not dropped until the first bell has tmer) reversed Into position again, consequently when the second belt empties Its toad Into the furnaoe the tremendous gas pressure, Instead of escaping, la con fined within the furnace, Thus tpduy It Is mltmated that moro than ntnety-rtv per nt of the. waste gsses of ths Ilethlehem 'teel Company's furnaces are utilised In .' .f :JI I -s ;4 ijyW .J tl Ckwjauy, H armor, turrets, gmu on iMti ,tov ,,AV PAGE ADVERTISEMENT OF " 0r-ri-i ) """" if trs 'gESi Ul v hd. &2B producing tha I.U.OOO-odd horaepower re quired to operito thli flcnntlo plant thla rnranlnir all of th dynamo, motor, crnnea and other mechanical equipment, theee baintr pasted throURh vraahera to cleanse them of Impurities.

Dut to return to tho blast furnaces, in (he smelting of Iron there are. three chief agencies bealden the ore Itself, thess being ooxa, nme ana compressed air. More than a million and a half tons of coke are consumed annually, the ooke bolnc omuincu rroin uie ovens or tne I,ohIgh Coal Company, two miles below the plant. About seventy per cent ot the resultant Iron Is used In a. molten state, tha remain der being made Into pig to all the general plant raqulremnt. For tho most part the molten metal Is carried In huge ladlaa to the open-beartli furnaces, about swy per cent of It being first passed through tha Bessemer convert ers, which reduce the carbon content and eliminate a large proportion of the manga nese and millcoti, the open hearth materially reducing the phosphorus.
