The accomplishment of this re- new construction work were started immediately. Operating from Nan, off-island camps were con- structed on Sites How and Oboe; drawings were released during June 1957 for these camps, and construction was virtually completed by late October. In February 1958 a small support camp was authorized on Site George, which was completed by mid-April. quirement necessitated the examination andtest- ing of 2,112,800 feet of existing cables and the installation of 114 million feet of 16-pair and 26-pair submarine cable.
