“Sure. I suppose a lot of our planes cross over the pass.”

“Quiet!” Gale warned. “I do hear planes, more than one, but they are far away.”

For a time they tramped in silence.

“Those planes are coming closer,” Gale murmured. “The sound is strange, not quite like a squadron of our own ships. They—”

“Look!” Jan exclaimed. “Up there ahead in that open space that’s like a clearing! There’s a queer light! Come on! Let’s have a look!”

Their rubber shoes making no sound, they sped forward to a bend in the trail. Then they saw it. A figure bending over a long stretch of flames in the trail.

“It’s a woman,” Gale whispered excitedly.

“A monk,” said Jan.

Woman or monk the figure darted into the brush.

And then the two girls saw it—a large, fiery cross burning in the trail.
