So the telephone-line came on apace, and long before the tower was finished, Charley had the line complete from the highway, where it joined the main line, to the summit of the hill where the tower was going up. He installed an instrument in a waterproof box nailed to a tree, so that he could now talk from the hilltop to the forester's office. When the tower was finally completed, he ran the lines up inside the angle-irons to protect them from the terrific winds, so that the tower man could instantly communicate with the forester at Oakdale. Now the cabin went up. Large, flat stones were assembled and a rough but stable foundation made below the level of the ground. Trees were felled, barked, squared on two sides, and properly notched at the corners. When a sufficient number had been prepared, the frame of the cabin was erected, log being laid upon log, with the corners dovetailing. Wooden pins held the logs in place. Windows and a door were cut out and framed. Then the rafters for the roof were fashioned, the sheathing nailed on, and shingles, made at a former lumber operation in Mr. Marlin's own territory, completed the job. A fireplace was made of big stones and concrete, and the cabin was about complete. A telephone extension was run into the building. At any time now a fire patrol could take up his twenty-four-hour watch at the fire-tower. The early rush of fishermen was past; but the fine weather still brought hosts of them into the woods, and the danger of fire increased rather than lessened. The scanty rainfall in spring had left the woods still dry, and now but few showers came. Fire patrols were still difficult to obtain, however, and Charley decided that he would take up his residence, at least temporarily, in the new cabin. There was ample room in it for two men, should a fire patrol be secured, and by living there, Charley would, of necessity, spend much time at this observation post. Night and morning and at intervals between, when he was at home, he could ascend to the tower and view every part of the neighboring forest. Furthermore, the location was very convenient, for the tower was close to the heart of his district. By living here he would be with his work twenty-four hours a day. Mr. Marlin approved of Charley's decision to move into the cabin. With the new road completed, the forester could come to the very foot of the mountain in his motor-car. He was in instant communication with his ranger by telephone and, when it was necessary, he could get to him by motor-car with the greatest ease.
