“It is!” they cried. “Hurrah for Miss Cullam!”

Ruth, however, despite the discovery of the possibly gold-bearing quartz, was not to be coaxed from her work. Each morning she shut herself into the “sanctum sanctorum” and worked faithfully at the scenario. Likewise, Rebecca stuck to the typewriter, for she had work to do for Mr. Hammond now, as well as for Ruth.

Some part of each afternoon Ruth took for exercise in the open. And usually she took this exercise on ponyback.

Riding alone out of the shallow gorge one day, she struck into what seemed to her a bridlepath which led into “dips” and valleys in the hills which she had never before seen. Nothing more had been observed of either the lone horseman or the supposed squaw for so many days that their presence about Freezeout Camp had quite slipped Ruth Fielding’s mind.

Besides, there were so many men at the camp now that to have fear of strangers was never in the girl’s thoughts. She urged her hardy pony into a gallop and sped down hill and up in a most invigorating dash.

Such a ride cleared the cobwebs out of her head and revivified mind and body alike. At the end of this dash, when she halted the pony in an arroyo to breathe, she was cheerful and happy and ready to laugh at anything.

She laughed first at her own nose! It really was ridiculous to think that she smelled wood smoke.

But the pungent odor of burning wood grew more and more distinct. She gazed swiftly all around her, seeing no campfire, of course, in this shallow gulch. But suddenly she gathered up the bridle reins tightly and stared, wide-eyed, off to the left. A faint column of blue smoke rose into the air—she could not be mistaken.

“Here’s a pretty kettle of fish!” thought Ruth. “Another camping party? Who can be living so near Freezeout without giving us a call? The lone horseman? The Indian squaw? Or both?”

She half turned her pony to ride back. It might be some ill-disposed person camping here in secret. Flapjack and Min had intimated there were occasionally ne’er-do-wells found in the range—outlaws, or ill-disposed Indians.
