he looked up again Rosalind saw there was
an odd, strained light in her eyes--a fear, a dread--a sinister something
that she shrank from. Rosalind remembered the killing of Marchmont, and
had a quick divination of impending trouble.

"What is it, Mrs. Levins? What has happened?"

The woman gulped hard, and clenched her hands. Evidently, whatever her
trouble, she had determined to bear it alone, but was now wavering.

"Tell me, Mrs. Levins; perhaps I can help you?"

"You can!" The words burst sobbingly from the woman. "Maybe you can
prevent it. But, oh, Miss Rosalind, I wasn't to say anything--Clay told me
not to. But I'm so afraid! Clay's so hot-headed, and Trevison is so
daring! I'm afraid they won't stop at anything!"

"But what is it?" demanded Rosalind, catching something of the woman's
excitement.

"It's about the machinery at the butte--the mining machinery. My God,
you'll never say I told you--will you? But they're going to blow it up

ran out to her horse. Once in the saddle she drew a deep breath and sent
the animal scampering into the flood of moonlight.

Down toward the cut the two men ran, and when they reached a gully at a
distance of several hundred feet from the dynamite shed they came upon
their horses. Mounting, they rode rapidly down the track toward the butte
where the mining machinery was being erected. They had taken the
handkerchiefs off while they ran, and now Trevison laughed with the hearty
abandon of a boy whose mischievous prank has succeeded.

"That was easy. I thought I heard a noise, though, when you backed against
the door and shoved it open."

"Nobody usually monkeys around a dynamite shed at night," returned Levins.
"Whew! There's enough of that stuff there to blow Manti to Kingdom
Come--wherever that is."

They rode boldly across the level at the base of the butte, for they had
reconnoitered after meeting on the plains just outside of town, and kn
