"Look out for stumps."

"I've got 'em spotted," muttered Tex.

"What's that?" swinging his gun quickly to the right. The horses
plunged, snorting, quickly to the left, the sleigh hit a snow-covered
stump, and it was only Tex's expert driving that saved it from
overturning.

"Some animal. I saw his hide." A hide Rand had seen, but it was the
coyote-skin coat of an Indian who had made one sign and instantly
vanished. Very quickly the dreaded halt came.

"Look out, Tex! There's a rifle barrel from behind that tree trunk."

"Halt!"

"Halt it is. There's nothing we can do." Was it Jo's presence in the
stage below that made him give in without a struggle, or did he know
that the Wells-Fargo box had vanished from under the driver's seat? Or
was it knowledge of the horde of yelling Indians which rose from the
snowy brush, and swooped down upon the shooting robbers? Four of them
were brought, in triumph, to the town on the stage.

"Where is the express box?" asked the sheriff.

"I do not know," answered Rand, defiantly.

"Cached away up on the mountain, I suppose, where the others are."
