head."

"Copperhead!" ejaculated the Superintendent in a low tense voice,
springing to his feet and turning toward the unconscious Indian. "He's
gone!" he cried with a great oath. "He's gone! Sergeant Crisp!" he
shouted, "Call out the whole Force! Surround this camp and hold every
Indian. Search every teepee for this fellow who was lying here. Quick!
Quick!" Leaving Cameron to the doctor, who in a few minutes became
satisfied that no serious injury had been sustained, he joined in the
search with fierce energy. The teepees were searched, the squaws and
papooses were ruthlessly bundled out from their slumbers and with the
Indians were huddled into the Barracks. But of the Sioux Chief there was
no sign. He had utterly vanished. The black prairie had engulfed him.

But the Police had their own methods. Within a quarter of an hour half
a dozen mounted constables were riding off in different directions to
cover the main trails leading to the Indian reserves and to sweep a wide
circle about the town.

"They will surely get him," said Dr. Martin confidently.

"Not much chance of it," growled Cameron, to whom with returning

"They certainly jumped in savagely," said Martin. "In fact I cannot
understand how they got at the thing so quickly."

"Didn't you hear him call?" said Cameron. "It was his call that did it.
Something he said turned them into devils. They were bound to do for me.
I never saw Indians act like that."

"Yes, I heard that call, and it mighty near did the trick for you. Thank
Heaven your thick Hielan' skull saved you."

"How did they let him go?" again groaned Cameron.

"How? Because he was too swift for us," said the Superintendent, who had
come in, "and we too slow. I thought it was an ordinary Indian row,
you see, but I might have known that you would not have gone in in that
style without good reason. Who would think that this old devil should
have the impudence to camp right here under our nose? Where did he come
from anyway, do you suppose?"

"Been to the Blackfoot Reserve like enough and was on his way to the
Sarcees when he fell in with this little camp of theirs."

"That's about it," replied the Superintendent gloomily. "And to think
