Is that one which speeds op talking by wire between New Tort dtj and Philadelphia a distance of about too miles. 8o great baa been the demand for telephone service between these two great aggregations of humanity that calls are made at the rate of about eight per minute or about 10.000 every 24 hours some !W0 telephone circuits being kept busy day and night Four underground cables, each enclosing en-closing hundreds of wires. In addition to two wlre-and-pole lines, are required re-quired to carry these messages and a fifth cable probably will be placed In service by the time this appears In Drint The underground cables used In tbls service are Ingenious contrivances. contriv-ances. They sre cvnsldeied storm-' proof, Insulated , against dampness and encased In a sheath of lead. Although Al-though less than three Inches In diameter, diam-eter, a sufficient number of wires can be packed Into one o them to permit 2B0 telephone conversations snd SOU telegraph messages to be transmitted at the same time by virtue of a special spe-cial apparatus which makes possible the sending ot many messages over comparatively few wires The amazing demand and consequent conse-quent rapid Increase in facilities for overcoming the handicap ot distance Is here Illustrated to tbe ntb degree. Tbe first telephone service between these points was Installed In 1889. Doubting Thomases regarded the service serv-ice ss sn experiment which might develop tnto s convenience, but never would develop Into s necessary service to tbe public, "The Greatest Bridge in the World" AMASTODONIO bridges, officially known as the Hudson River orldgs, but referred to ss Tbs Greatest Great-est Bridge In the World," wblcb will cut the sir high above tbe waters of this famous and lordly stream between the Palisades of New Jersey snd Riverside Riv-erside drive, New Tors, Is under construction. con-struction. i ta an attempt to cope (with tbs probable prob-able traffic demands of future generations, genera-tions, man bas dared to build a bridge of such gigantic proportions as to stagger stag-ger the Imagination. Tbs bridge proper prop-er will jump the river In a single spsn 8,500 feet long, while Its length, exclusive ex-clusive of the ornate plazas which srs planned for either end. will be 7.800 feet Its two piers, resting on bed rock, will each be 210 by 65 feet st base and tower 635 feet above tbe water wa-ter and Its floor, which will bs 253 feet above the water, will have an ultimate width of 188 feet The weight of the auspended construction will approximate ap-proximate 00,000 tons, supported by cables containing 26,474 wires , each and three feet thick. The design adopted admits ot expanding ex-panding the capacity as necessity demands. de-mands. Originally, Its one deck will carry four lanea of vehicular traffic and two sidewalks. Later, two 24-foot 24-foot roadwaya can be added. Finally, a second deck can be swung under the first one, providing for from two to eight tracka for rapid transit service, bringing the maximum capacity ot the structure np to something like 80,000,-000 80,000,-000 vehicles annually. All told, this Is one of the most difficult construction construc-tion feats yet attempted by man. m m m The Moffat Tunnel AFTER years of tedious boring through six miles of solid rock snd tbe expenditure of sbout f 18.000,-000 18.000,-000 tbe Moffat tunnel, carrying twin steel rails through tbe backbone of this continent fifty miles northwest of Denver, was completed In 1928. This Is the highest tunnel In tbe world being upwsrds ot s mile snd s half above the waters In the seas, notwithstanding which some ot the peaks of the Continental Divide tower tow-er half a mile above the track. It measures 10 reet by 24 feet and was built with s high-point st the center so that seepage wster would readily drain away. It Is 23 miles shorter and 2,400 feet lower than tbe previous pre-vious route wblcb squirmed over "The Divide" through that bleak canyon can-yon known as Rollins Pass. . This tunnel promises to become a national asset , of no mean Importance. It provides s gateway between a territory ter-ritory in Northeastern Colorado and Eastern Otah that Is larger, than France and. tla claimed, holds enough coal to supply this country for several sev-eral centuries, oil shale beds capable of producing enough ammonium sulphate sul-phate to fertilize all the farms In the Mississippi basin, billions of feet of timber and millions of acres ot public pub-lic lands open to entry end some 40,000,000 persons who people that great area between the Rockies and tbe Alleghenles. When the railroad Is completed to Salt Lake City It will materially shorten the distance between be-tween Denver and the Pacific coast and will thus operate to speed np transcontinental traffic. 135. llll Weatern Newenaper Onion,) |
