Janus, caught off his balance, did exactly what Harriet Burrell had foreseen he would do. The guide was jerked from his feet, and, throwing out both hands before him to protect himself, went shooting down the incline headfirst.

"Grab the rope!" he shouted, as he pitched over.

In the meantime something was happening to Grace Thompson. No one having grabbed the line, she, too, shot backward head first.

Harriet, fearing that the girl's head would be crushed when she reached the bottom of the slope, sprang forward, and, bracing herself, stooped over with her hands close to the ground. It all happened in a few seconds. Jane had barely time to collect her thoughts when Tommy was caught in Harriet's net. Harriet had caught her by the shoulders and stopped the force of the slide, but in doing so she herself toppled over backward.

Jane uttered a war whoop. Her joyous shout died a sudden death when the oncoming Janus collided with her, bowling Crazy Jane over. She quickly rolled out of the way while the guide continued on over the edge, tumbling down a second incline to the surface of a flat rock about eight feet below.

Tommy got up, gazing about her in mild amazement.

"Did thomebody fall down, Harriet?" she asked.

"No, somebody fell up," jeered Jane.

"Look after Mr. Grubb," cried the guardian; "I fear he is hurt."

Janus pulled himself slowly to a sitting position, and took an inventory to make sure that he was all there and still fastened together. For the moment he was not quite clear as to what really had occurred. When he saw the blue eyes of Tommy Thompson peering over at him, he remembered.
