“You couldn’t get in here with anything but a Henry,” laughed the forester.  “This old bus has taken me lots of places you would never have believed possible.”

He took the key from the switch on the dashboard, and the two stepped to the ground.  Charley wondered what the forester intended to do, but by this time he knew enough not to ask questions.  The forester started up the trail with him.  When they came to the big battery Charley understood, for without a word the forester took Charley’s little axe and began to chop poles to carry the battery with.  In a few moments these handles were bound fast.  The forester tossed the traps over his shoulder.  Charley tied the amplifier box to his belt.  Then they picked up the battery and started toward camp.

Suddenly Charley stopped.  “By George!” he cried.  “I forgot all about the pup.  I wonder where he got to.”

He whistled and whistled, but apparently in vain.  They went on, and at intervals Charley whistled for the dog while he and the forester were resting.  Still no dog appeared.  Charley’s face grew long.  “Gee!  I’ll miss that pup,” he said regretfully.  “Why didn’t I think of him sooner?”

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.”
