North and west, in the direction of Yellow Bird's people, went Jolly Roger and Peter after that night.

They traveled slowly and cautiously, and with each day Peter came to understand more clearly there was some reason why they must be constantly on their guard.

His master, he noticed, was thrillingly attentive whenever a sound came to their ears--perhaps the cracking of a twig, a mysterious movement of brush, or the tread of a cloven hoof.

And instinctively he came to know they were evading Man.

He remembered vividly their escape from Cassidy and their quiet hiding for many days in the mass of sun-baked rocks which Jolly Roger had called the Stew-Kettle.
