the long dis-tance cable network serving the Eastwith that which serves the Pacificcoast. Last year communications facilitiesalong the eastern seaboard routeswere supplemented by important ad-ditions on various links all the wayfrom Boston to Florida. Here, car-rier systems provided many new channels along the Atlantic coast, asdid they also along the fourth trans-continental line from Oklahoma Cityto Los Angeles. An important extension scheduledfor this year is that of twin un-derground cables linking Richmondand Norfolk, Va., to serve Nor-folk, Newport News and the vi-cinity, where there are concentratedextensive ship building, naval, andarmy activities. Others planned forthe next few years include twin under-ground cables about 700 miles inlength, from Atlanta, Georgia, to Mi-ami, Florida; a new cable betweenLos Angeles and San Diego; and twincables between Seattle and Portland.A second cable to be placed alongeach of several existing routes willsubstantially increase long distance

THE FIRE ROOM WATCH AT SEA On a modern battleship, the fire room watch maintains telephonic communication with other departments 14 Bell Telephone Magazine facilities into the southwest, whereArmy activities on a large scale, par-ticularly aviation, will be centered.This program envisions by the end of1943, exclusive of the transcontinen-tal route mentioned above, cable con-struction on more than 4,000 miles ofprincipal toll routes which are nowserved by open wire. The construction of these new ca-bles will be accompanied by the ex-tension of the network of broad bandtelephone transmission systems. Car-rier systems are being superposednot only on new cable facilities but onexisting cable routes. Circuits so pro-vided are of high quality and are par-ticularly well suited for use in estab-lishing alternative and protection cir-cuit routes. Each of the multi-cableroutes, as proposed, can accommo-date as many as 50 or more carriersystems, each of which will providetwelve telephone circuit
