"Then let us have a shot at them."

Together they raised their guns and fired, and two Indians dropped dead in their tracks.

The rest, looking up the stream, saw the two white men, and a dozen of them sprung in pursuit.

"Now run for the falls," said Kelly, and he led the way.

They arrived at the opening several rods ahead of the Sioux.

"Here," said the scout; "you stay here, and shoot every one that makes his appearance. I will take care of your horse."

He led the horse to the door leading to the middle room, and giving the signal, was admitted without delay.

Passing in, he tied the horse near his own, and shouted:

"Come, Curtiss, Bear-Paw, get your guns and come out; there is some fun for you!"

The two men sprung up and followed him, and were soon beside Jehiel, waiting for the Sioux to make their appearance.
