The darkness of night had closed in all around them, and the only light was that of the smoky lantern, and from the few stars that shone down through the tree tops.

"There she is!" cried Dick, swinging the lamp up over his head.

And in the widening circle of light the three youths beheld the biplane, resting exactly as they had left the craft.
"Thank goodness!" cried Tom.
