“Very well,” agreed Frank. “We shall look for you to-morrow.”

“Yas.”

The Steam Horse was brought to a stop and Beaver Bill left the wagon.

He proceeded to loosen the saddle from his pony’s back and give him freedom.

Fortunately there was a brief space of green grass here, and the little animal was enabled to get a bite.

The Steam Horse went on to the entrance of Death Valley.

Soon a plateau was encountered and crossed, then a plain beyond it, and then the travelers saw the pass before them.

Upon either hand rose mighty walls of rock.

It was like the veritable gateway to a Hades, and in spite of themselves all experienced a queer chill.

But Frank kept on until the Steam Horse was fairly in the pass.
