"Things are getting down to a fine point, Tom," warned Beverly. "Our gas is on its last legs, and any minute now we'll find ourselves without motive power."

"It must change soon," the pilot told them. "This scrub forest has got to give way to rising ground and open spaces."

"But if it doesn't, what then?" asked Jack.

"I hate to think of crashing down into those trees," Tom admitted. "We've just got to get over being too particular. Several places we let pass us might have answered our purpose. Look ahead, Jack, and tell me if there doesn't seem to be some sort of open spot lying there."

Jack gave a whoop.

"Here we are!" he cried exultantly. "It's an opening in the scrub timber, a big gash too, for a fact! Why, already I can see that it looks like a level green field. How queer it should be lying right there, as if it might be meant for us."

"You don't glimpse any other chance further on, do you, Jack?" continued the pilot.

"Never a thing, Tom. Just a continuation of those same old dwarf oak trees. But why do you ask that? What's the matter with this fine big gap?"

"I'm afraid it's a marsh, and not a dry field!" Tom answered. "But all the same I presume we'll have to chance it. Better to strike a bog than to fall into those trees, where the lot of us might be killed."

"Suppose we circle around, and try to find the best place for a descent," proposed Beverly.
