Danger comes to these men frequently and difficulties daily, and it is theirs to test the truth of Byron's line, "There is society where none intrudes."
The cable line from Seattle to Sitka and thence to Valdez, with the branches established, was laid under
the direction of General James Allen and Major Edgar Russel, who were chosen for the work because of their cable laying experiences in the Philippines and of their high knowledge of electric engineering. The cableship, Burnside, was brought from China where it was undergoing repairs. The cable was manufactured in New Jersey and transported around Cape Horn, a distance of 12,000 miles. The work of laying was prosecuted in large part under the most unfavorable circumstances, gales and bad weather generally delaying operations and frequently endangering not only the success of the work but the safety of the

Alaska, enough to make a battalion of infantry of ordinary peace time strength. A few soldiers of the line, mainly infantrymen, have been detached for service with the Signal Corps in the Alaskan work. These men in little squads, barely enough in many cases to complete a set of fours, are stationed at long intervals on the rude roads and the blazed trails above which the wires of the telegraph are strung. Nine months of winter cach year these soldiers remain cut off from anything save a humming wire to remind them that somewhere men live in cities and go to their work in the companionship of multitudes.
The soldiers of the Signal Corps in Alaska must fight the elements. For two years during the construction of a part of the land lines a little squad of service men made their headquarters in a log hut as primitive in building fashion as any ever thrown up by a pioneer forefather when the tide of migration flowed over the Alleghenies in the New West. Two years, eighteen months of winter, working daily with the thermometer marking degrees way below the zero point, these soldiers stayed there, ap
