Charley's mind worked like lightning. Even as he examined and located the smoke columns, he was planning how best to extinguish the fires. It was still very early. The wind would not rise for hours yet. Even then the dense timber would break its force. Meanwhile the fire would spread but slowly. If only he could get his men to the spot in time, Charley felt sure he could put out every blaze with but slight damage done. By the time he reached for the telephone, he had his plan of campaign mapped out. Morton's big crew would be assembling in a short time. The forester might be able to hasten their assembling and to collect more men. With trucks he could rush the gang clear to the foot of the mountain, where the broken army truck lay. An excellent fire trail would take some of them afoot direct to the first blazes. Other groups could strike through the passes for the other fires. With the chief and Mr. Morton and himself to head three of the crews, and experienced fire fighters to lead the other groups, Charley felt sure that they would hold the fires. Sharply Charley whirled the bell handle and put the receiver to his ear. There was no response. Impatiently he rang again. Still he got no reply. A feeling of alarm took possession of him. Frantically he rang and rang, but the receiver at his ear was mute. The wire was cut. "Thank God for the wireless!" cried Charley, snatching up the trap-door and descending the ladder recklessly. "There aren't any wires about that to be cut." Involuntarily he glanced toward his aerial. Then he stopped dead. His aerial had disappeared. Now he knew why the tower had vibrated during the night. Somebody <i>had</i> been on the ladder. If only he had gotten up to investigate! But it was too late now for regrets. He must act. He must get up another aerial. An idea came to him and he shouted for joy. He would use the tower itself as an aerial. He raced to the cabin and flung open the door. A single glance showed him his cupboard had been rifled of its food supplies. He leaped toward his operating-table and stopped aghast. His face turned pale, his hands fell helplessly to his sides, and he stood looking at the instruments before him, the picture of despair. A heavy file lay across the terminals of his battery, and the battery was useless. Unnerved, Charley sank down on a chair. He covered his face with his hands. It would take him hours to reach the Morton home on foot. And it might be hours more before the forester could be notified. It looked as though the forest were doomed. Fairly shaking himself, as a terrier shakes a rat, Charley freed himself of the fear that clutched at his heart and forced himself to think. Calmly he began to consider what he could do. He thought of the dry cells he had first used. They were still wired together and in the cabin. Like a flash Charley coupled them to his instrument, but the cells were exhausted. He could get no spark from them.
