He could see just one possibility of success. Undoubtedly there was a great deal more of the green pasteboard in the world than had been contained in the burned box. Hence persons other than the incendiary must have some of that same pasteboard. Perhaps some of those persons might bring a bit of it into the forest. Campers and fishermen often brought food and other things into the woods in pasteboard boxes. So Charley resolved to examine carefully every camp he came to, and even to scrutinize the remains of camp fires. But day followed day and Charley found nothing to enlighten him.

One day when Charley was on his way to meet the ranger, he suddenly realized that he was away behind time. Charley hated the idea of being tardy, especially when he had no reason for being late. He had been training his dog, and his work with the pup had delayed him more than he realized. But with haste he could still reach the meeting-place on time.

At the fastest pace that he thought he could hold Charley set off. His daily hikes through the forest had rapidly made a good walker of him, and now he went along at a rate that would speedily have tired out most travelers. Sometimes, to rest himself by changing his gait, he went scout pace, walking fifty steps, then jogging fifty. He allowed nothing to hinder him or take his attention. When he reached the meeting-place it still lacked a few minutes of the appointed hour. Charley was pleased to find that he had arrived before the ranger.

When the time of meeting came and the ranger was not there, Charley began to scan the fire trail carefully and to look about for smoke clouds. He knew that something of moment must be afoot to make the ranger tardy for his appointment. The ranger was not visible, however, though Charley could see straight down the fire trail for a long distance.

"I'll go meet him," said Charley. "He's sure to come this way."

In the sand of the trail he printed a message for the ranger, in case the latter should be coming by an unaccustomed route, and continued along the trail. He had gone a full mile before he met Mr. Morton.

"Sorry I am late, Charley," said the ranger. "A lot of stuff came to the office for you last night and the chief asked me to fetch it out this morning. I think your new battery has come."

"It's about time," said Charley. "I had about given up hope of ever seeing it." Then he added, "But you couldn't pack that way out here. It must weigh sixty pounds."

"Is that all?" laughed the ranger. "I had come to believe that it weighed in the neighborhood of half a ton."

"Did you really try to carry it?" asked Charley.
