Night was at hand when the two reached Charley's camp. Nothing had been disturbed. Charley took advantage of the remaining daylight to couple up the battery and the amplifier to his wireless. He tested the outfit and found he had a strong spark that cracked like a whip when he touched the key. "Look at that!" he cried. "Now I feel better. I can always get into communication with somebody now." "You aren't a bit more pleased than I am, Charley," smiled the forester. "I'll take back all I ever said about the wireless. If Morton can learn to talk by wireless, the rest of my crew can also. When the dull season comes, I'll start a radio school with you as instructor and we'll make every man in the service learn to operate the wireless. The Department ought to be glad to supply a good outfit; but if we can't get the money, we can at least make some outfits like yours. We're going on a wireless basis or my name is not Marlin." The forester was interrupted by a joyous bark and in rushed Charley's pup. "You blessed little fellow," said Charley, fondling the animal. "I suppose you lost our trail when we got into the motor-car and you probably hung around the battery all day and followed our trail back here. That's pretty good. You've got great stuff in you, pup. The next thing I teach you will be to stand guard over things as you probably did over that battery to-day." Darkness fell. Supper was cooked and eaten. "Have you heard that cat lately, Charley?" asked the forester. "No," replied Charley, "but I think I'll put the traps out anyway." "We can attract it even if it isn't near by," said the forester. "Have you a can of salmon that you can spare?" "Sure." "Then give me the traps and bring your can." Charley got the things asked for. The forester, taking the flash-light, led the way through the thicket to the open forest. At some distance from the camp the forester stopped and turned the beam from the search-light upward. Finally he found what he was looking for--a small branch about seven feet from the ground. Then he cut the top of the salmon can, and punching holes in the sides near the top, fastened a string to the can and suspended the can from the limb. Then he set the traps in a circle under the can, fastening the chains to convenient saplings, and threw two or three small pieces of the salmon on the ground within the circle of traps. Then they made their way back to camp. Charley lighted a little friendship fire in the fireplace the ranger had made, and the two sat down beside the flames. It was little more than three weeks since Charley had first entered the forest. During that time he had really seen very little of the forester. Yet as he sat beside his chief, Charley felt as though he had known him always. A common emotion had drawn them close together this day, and somehow Charley believed that his feeling of affection for his chief was fully reciprocated. For a time they sat in silence, each busy with his own thoughts.
