Moreover, the spacing of the oldercoils was not sufficiently regular forsatisfactory repeater operation. Sothe Long Lines men began the workof replacing loading coils and respac-ing them throughout the length of themost direct route from New York toDenver. Respacing loading coils ne-cessitated installing a prodigious num-ber of new transpositions, with theattendant cutting and splicing of wireson working circuits. And because notelephone engineer is content to relyupon a single strand of communica-tion when it is practicable to provide 19^0 The Circuits Go Up 29. Heavy Going Humboldt Lake, in Nevada, is Utile more than a swamp, but it made pole-setting an arduous task a second string for his bow, similaroperations were performed upon a sec-ond route between New York andChicago. One extremely formidable problemfor the telephone engineers was thatof cable. At that stage of longdistance telephony, even the smallamount of cable necessary to carrylong distance lines into or through acity had a serious effect upon thetravel-weary currents. Fortunately,it had for many years been the prac-tice in building long distance lines toskirt large centers, as a consequenceof which these lines went into verylittle cable; so that, on a percentagebasis, the amount of cable in the line ultimately set up for transcontinentalservice was what the chemist wouldcall a trace. The first pole of theaerial wire line was located in JournalSquare, Jersey City. It would be interesting to go backin time and look at that first trans-continental line
