fence, a chimney—anything that would be man-built; but his efforts were unrewarded.
At the verge of the forest he halted, fearing to enter; but at last, when he saw that the wood was more open than that near the ocean, and that there was but little underbrush, he mustered sufficient courage to step timidly within.
On careful tiptoe he threaded his way through the parklike grove, stopping every few minutes to listen, and ready at the first note of danger to fly screaming toward the open plain.
Notwithstanding his fears, he reached the opposite boundary of the forest without seeing or hearing anything to arouse suspicion, and, emerging from the cool shade, found himself a little distance from a perpendicular white cliff, the face of which was honeycombed with the mouths of many caves.
There was no living creature in sight, nor did the very apparent artificiality of the caves suggest to the impractical Waldo that they might be the habitations of perhaps savage human beings.
With the spell of discovery still upon him, he crossed the open toward the cliffs; but he had by no means forgotten his chronic state of abject fear. Ears and eyes were alert for hidden dangers; every few steps were punctuated by a timid halt and a searching survey of his surroundings.
