six feet long and thicker thanthe cable, as one AT&T engineer says — plaguedworkmen. Underground springs in other areas con-verted the cable trench into a river bed and requiredthe construction of small temporary dams. And atsome points, rock formations required blasting be-fore they would give way to the giant teeth of trench-ing equipment. On most small streams the cable canbe placed directly in the water, but larger rivers likethe Savannah and the Hudson require piping andspecial submarine cable. Each step is carefully inspected before the nextphase is started. One Long Lines inspector estimatesthat he will walk through four pairs of shoes andcover more than 1,000 miles on foot before his sec-tion of the project is completed. Thirteen units of the Bell System, coordinated by the Long Linesdepartment of AT&T, have joined forces in the cable project. Thecable was manufactured at Western Electrics Baltimore Workswhere, at left, it is being tested to insure dependability. 23
