The erection of the tower was another task for which Charley would be responsible. Long before the road was completed, therefore, Charley and the forester went over every step in the process of construction, and decided how to do each task, from the making of the concrete foundations to the stringing of the telephone wires when the tower was complete. The tower itself was to be a slender steel structure made of angle-iron supports bolted together, with a little square room at the top for the watcher. This room would be enclosed on every side with glass windows, and from this great elevation a watcher could see in every direction over miles and miles of forest. A telephone would connect with the forester's office. At the foot of this tower Mr. Marlin intended to build a snug, little cabin, so that the tower man could remain at his post twenty-four hours a day throughout the fire season. The materials for the cabin would be trucked in along the new road and carried up the mountain, and some of them would be cut right on the spot; for the forester planned to erect a neat log cabin. Before the road was completed, Charley had cement carried in as far as the trucks could travel. Then the cement was carried up the mountain by laborers. It had been put in small sacks so that it could be handled easily. Sand was already at hand, and water could be had at the run coming from the spring by which Charley had camped. Tools and boards were brought, the proper excavations made, forms fashioned and fitted into the excavations, and then cement was mixed and poured into the forms to make the foundation to which the tower was to be bolted. By the time the road was finished so that the steel framework could be trucked in, the cement foundations were hard as stone and ready for the instant erection of the tower. At once the steel frame began to ascend. Upright was added to upright, cross brace bolted to cross brace, and rung after rung added to the steel ladder that led up to what was to be the watch-tower. In a surprisingly short time the steel work was completed. Now the forester brought in skilled carpenters and the wood for the tower room was cut after the patterns and the cut pieces hoisted up to the top of the steel frame where the watch-tower itself began to take shape. While these operations were afoot, Charley and his laborers were back in the forest, running a telephone-line along the new road. Holes had to be dug, poles cut, barked, hauled, and set up, and the wires strung. While his men set the poles, Charley himself, with a helper, strung the wires. At this job he needed no instruction. His experiences with the wireless were now of great value to him, for he understood about insulation, grounding, short circuits, and the like as well as any skilled lineman.
