"Like a square tower with windows!" prompted Fred, glad to have his suspicions confirmed.

"I guess that's one of these lookout towers," said Carl, when he inspected it. "Pretty high up, though."

"Let's go up that way," suggested Herb. "Might as well as any other. Looks easier to climb, too."

"I'd like to get a picture of it to take home too," said Fred, whereupon Jerry grabbed his hat, and gave him a tussle for it.

"Don't you want one of the windows for a souvenir," joked the Southerner. "Gee, I wish I'd gone into the souvenir business before you came. I'd gotten rich off of you."

It was finally decided, however, to follow the direction Fred had chosen, principally because it seemed to be less thickly timbered.

It was a problem what to do with the pony. He would stand without tethering, but he might be bothered by wild animals.

Carl, however, soon solved the problem by clearing the ground for several feet around him, and then, gathering twigs and sticks, piled them around the pony in a wide circle. He then set fire to them, and, after they had a good start, smothered the flames carefully so they emitted a thin line of smoke.

"I think that'll keep most animals away," he said, as they started for the climb.

"It wouldn't take us long to get up there if we had our aeroplane," said Fly. "Would it, Hawke?"
