Against the green pinyons Frank's white horse stood out conspicuously, and near him browsed the mounts of Jim and Wallace.

The boys were not in evidence.

Concluding they had gone down over the rim, I dismounted and kicked off my chaps, and taking my rifle and camera, hurried to look the place over.
To my surprise and interest, I found a long section of rim wall in ruins.

It lay in a great curve between the two giant capes; and many short, sharp, projecting promontories, like the teeth of a saw, overhung the canyon.

The slopes between these points of cliff were covered with a deep growth of pinyon, and in these places descent would be easy.
