Iws, ' SOME WONDERFUL ENGINEERING FEATS ACCOMPLISHED IN AMERICA Imagine a roacky coast lino with an cBtunry stretching miles Inland to where two glaciers roar their ley faces 300 feet abovo tho water. On clthor sido and Inland as far as tho eyeB can seo are ragged mountains cleft by canyons of sickening depth. In winter all is burled beneath a dozen feet of snow; In summor It Is a placo of chill fogs and ruBhing etroaniB that often double their depth In a single day. , . Such is tho site of tho Copper River Kailroad in Alaska. As a. feat of en gineering this railroad today stands aboalutoly alone. Its builders faced problems never boforo met by any other engineers. They started tho great work with prophesies of failure ringing in their ears. In a land of such cruel wlntors and such sudden climatic changes It seemed as If thoso wiio riskeu nrteen million dollars on the lino woro foolB as woll as dream ors. But they won tho stako and how they won is an inspiring story. To begin with, tho Coppor River Railroad is only 193 miles long, but it coat $70,000 a mile to build It. Tho discovery of rich deposits of anthra clto coal and copper In tho northwest ern part of Alaska made such a road necessary unlcBB tho now treasure houso that had been opened up was to bo allowed to koop Its good things for ever locked up from man. Tho only possible route carried the tracks across tho Copper Rlvor. This stream Is tho-mUIerforhtrinoltcdwatcre of Copper Rlvor Valloy would be Impass able, as Indeed it was considered for many years. To get material and supplies across tho water that washed thoBO two cliffs of. Ice was tho first problem tho onglneors faced. A tem porary brldgo was not to bo thought Of. Tho first flow nf Ic.n wnnlrl hnvn carried It away like a houso of cards. It was finally decided to establish a forry. A heavily timbered boat was brought up from tho coast. On this clumsy craft, stationary en glnos, construction locomotives and cars, as woll as ties and tracks, woro transported across tho rlvor, often at great risk of life. Of course, none of the heavy mate rial for tho brldgo could bo brought there until tho track had beon finiBhod from tho eaBt to tho edge of tho river. But before this was done material was uosireu for the building of the lino from tho western bank of tho stream. TIiIb was brought in up tre river from tho coast in heavy river boats, each handled by a crow of fifteen hardened rlvermon and guides. It was impos sible to paddle or sail any great part of tho way, and during most of tho Journey tho boatB had to bo towed along tho shore 'by tho men them selves. Tho boatmon woro often forcod to wado for miles through water waist deep and as cold as ico could mako it. In winter it would seem to" have been an easy task to bring tho supplies un 4ho frozon surface of tho river on tho great Miles and Chllds glaciers and It stretches from tho foot of the ice of the Bohrlng sea. AcroBB this, almost at ,the base of tho glacier, it was necessary to erect a 1,150 foot bridge. In that arctic land literally hundreds of miles from any baBo of supplies there is today one of the flncBt railroad bridges in Amorlca. JLia built on. concrete piers that defy both floes and icebergs. In fact one of tho piers 1b itself sot in a base of glacial Ice which In that climate la as unchanging as stone. Tho contract called for tho comple tion of tho road in1 two years. ThlB meant that tho IrackB would bo laid east and wet from tho river at tho same time that tho brldgo was being built. But a groat many reputable en gineers were not at all suro that the brldgo could ever, bo flnishedr Its' lo cation wa salmost In tho shadow of thoBo two frowning cliffs of Ice. In spring and summer great pieces were constantly breaking off and crashing down Into the water, there to rush to ward the sea in tho form of Icebergs, sweeping away anything that got in their path.

If the brldgo should fall tho rest of tho line would be useless and its en tiro cost of ?15,000,000 would bo lost. Tho plans called for a four-span steel brldgo resting on concroto piers forty feet abovo normal water level to allow for floods and tho passage of Ice. AIbo several barriers wore to bo built between tho brldgo and the gla cial wall to intercept as much ico as possible. Woro it hot for tho fact that tho MileB and Chllds glaclerB Bpllt long bo foro they reach tho soa Into two sep arate wallb of moxng Ico, each pre senting a face three miles long, tho Blodges But this was not so slmplo as It sounds. Even in winter the cli mate in that portion of Alaska is bo low, zoro one day and melting tho next. Here thero will bo a solid mass of ico and Just over tho next rise there may be five feet of water. Thousands of tons of brush woro laid on tho surface of the Ice In an effort to maintain a passable sledge road, but at best it was terrifically Tiard going. The brldgo piers, three of which woro in deep water, wero built in the dead of winter. ThlB work had to bo done through holes cut In ico seven foot thick. The molds for tho con crete wero then sunk from forty to Hfty foot through tho water and tho river bottom tr bed rock. Theso molds wero heavily Umbered boxos, thoir outsldes armored with a succes sion of eighty-pound railroad rails. Abovo the molds ico barriers of rails woro also sunk. Tho engineers know that if thov could got tho molds and piers down before tho spring break-up they would bo safe. For the rlvor is tamo only when holdip. Its winter prison. In fer in a cllmato that was frequently twenty-flvo below zoro swopt away by tho Ico that was growing less stable overy hour. Also tho tlmo of tho contract would terminate with tho coming of spring, and when tho first bolt was placed a margin of only six weeks was loft. Span No. 3, which was 460 feet from pier to pier, was tho most dlfllcult, for It was In tho direct lino of tho greatest current and the heaviest flow of Ico. Bjr the bars spaco of an hour this span was saved from complete destruction. While tho uncomDlotod steol-work-stlll-rostod-on tho tempore ary pile foundation it was discovered that It had slipped an inch out of alignment. This moant that tho Ico was moving. Tho break-up had start ed. In a few days the river would be a mass of churning Ice and great bergs. Unless the span thon rested solidly on Its permanent concrete foundations, It would bo swept away. Tho first day's slippage of an Inch Increased next day to two, thon to three, to four, and finally tho whole span was fifteen Inchos out of line. Tho rlvor was nlfln rifling. T oltmlnvl twenty-two feot whilo tho men un bolted and shifted beams and girders to get thorn out of harm's way. If the pllo foundations could bo saved tho bridge would be safe. As a last desperate resort every "donkey en glno" boiler on tho Job was fired up and steam from scores of feed pipes was turned on tho ico to keep It clear of tho temporary basOB. !For days every man worked eighteen hourB in the damp cruel weather of an Alaskan spring to save tho brldgo. Heavy anchorages wero built Into tho ico upBtream and by means of block and tackle tho slipping span was ilterallydEaggedbackinto-itB-proper- alignmont. When this was done tho iron workers sot with frantic haBte to bolt tho steel parts together, for tho piles could hold but a few days longer. Just an hour after tho last bolt was placed, tho last block knocked out and tho Bpan dropped upon its safo bed of concrete, tho ico broke up with an angry roar and tho temporary foun dations wont downstream like so much driftwood. But tho bridge had been built. It defied tho glaciers. There Is not space hero to detail tho hardships of tho men who laid tho tracks across tho ruggo dsurfaco of tho land east and west. Washouts and avalanches woro almost of dally oc currence. Onco a rotary snowplow, pushed by two locomotives, started out- to clear tho twenty- foot drifts from tho tracks to tho base of supplies fifty mlleB away. It disappeared In a white wave and was not seen until a month later.
