They made a rush for it.

Whether they were panic-stricken, or whether he was too close on their heels for them to attempt to scramble up the bluff to the crevices, I do not know; but at any rate they dashed into the wide-mouthed cave wherein Lop-Ear and I had played the afternoon before.
What happened inside there was no way of telling, but it is fair to conclude that the two Folk slipped through the connecting crevice into the other cave.

This crevice was too small to allow for the passage of Saber-Tooth, and he came out the way he had gone in, unsatisfied and angry.

It was evident that his night's hunting had been unsuccessful and that he had expected to make a meal off of us.

He caught sight of the two Folk at the other cave-mouth and sprang for them.
