Steel Reinforcement Made theConcrete Pole Possible Not until about 1895 was steel used as reinforce-ment, when concrete poles so reinforced were triedout both here and abroad.

Thiswas doubtless due to failure to appreciate the faultsof the new construction until the poles were made, anda bad attack of cold feet on the part of the enthusiastsimmediately thereafter. A few, however, stuck to the problem, and by 1910the reinforced concrete pole had become a reasonablypracticable structure. Credit for this result is dueparticularly to the Concrete Pole Company of , Ont., which built several hundred for trans-mission lines in the Welland Canal district; to GeorgeA. Cellar, superintendent of telegraph PennsylvaniaLines west of Pittsburgh, one of the earliest in the field;to the United Traction Company, Albany, N. Y.; and. •Made It Myself, SaidCan You By Charles Rufus Harte Construction Engineer The Connecticut Company, New Haven, Conn. to several others. Since 1910 very satisfactory resultshave been secured, although the development has beenchiefly local. A few companies, notably the ClevelandRailway; the Fort Wayne & Wabash Valley TractionCompany; the Marseilles Land & Water Company,Marseilles, 111., the New York State Railways; the Okla-homa Gas & Electric Company and the Welland Canaldistrict companies have used very considerable num-bers, while but few other companies seem to haveemployed concrete poles at all. The life of a reinforced concrete pole depends onseveral factors. The concrete itself is practically ever-lasting as regards decay orcorrosion, but it may failthrough a mechanical reinforcement cannot rustso long as it is sealed in thepy^f^H concrete and it is also thus protected from injury to the coveringconcrete may expose the met
