CONQUEST OF DISTAXCE BY WIRE TELEPHONY 369 



"By using the underground in connection with the overhead, the Seaboard cities 

 from Washington to Boston could be no longer isolated by storms destroying the 

 overhead wires." 



The storm-proof communications objective having been achieved, the 

 remaining sections of the coarse-gauge quadded cable project were installed 

 in accordance with the need for additional circuits in particular sections of 

 the Boston-Washington route. These additional coarse-gauge cables be- 

 came available for service in the following sequence: Boston-Providence, 

 November 1914; New York-New Haven, April 1917; and New York- 

 Philadelphia, 1918. The listed dates apply to the initial loading comple- 

 ments, which usually included all of the 10-gauge quads and half of the 13- 

 gauge quads. 



Several of the shorter sections made use of a new cable layup having 3 

 quads of 10-gauge conductors, 30 quads of 13-gauge conductors, and 18 

 pairs of 16-gauge conductors. This change in layup was a significant result 

 of the new repeater developments then current, which greatly reduced the 

 need for 10-gauge circuits. By dropping out 4 quads of 10-gauge conduc- 

 tors and the 6 interstice 13-gauge pairs (a total of 18 circuits), it was possible 

 to provide 12 additional quads of 13-gauge conductors, giving a net gain of 

 18 circuits.
