“It’s a go. Keep on with the quarrel, Rattleton.”

Harry did so, and in a very few seconds they were at it in a manner that seemed intensely in earnest. Their voices rose higher and higher, and they scowled fiercely, flourishing their clinched hands in the air and shaking them under each other’s nose.

Browning got into the game by making a bluff at stopping the quarrel, which seemed to be quite ineffectual. He seemed to try to force himself between them, but Rattleton hit him a hard crack on the jaw with his fist, with which he was threatening Diamond.

“Scissors!” gurgled Bruce, as he keeled over on his back, holding both hands to his jaw. “What do you take me for—a punching bag?”

“You have received what peacemakers usually get,” said Harry, as he continued to threaten Diamond.

The Indians looked on complacently, their appearance seeming to indicate that they were mildly interested, but did not care a continental if the two white boys hammered each other.

Jack scrambled to his feet and dared Harry to get up. Harry declared he would not take a dare, and he got up. Then Bruce and Toots lost no time in doing likewise, and, just when it seemed that the apparently angry lads were going to begin hammering each other Browning cried:

“Ready!”

Immediately the boys made a leap for the bicycles, caught them up, formed a square with them, and stood behind the machines, like soldiers within a fort.

The Indians uttered shouts of astonishment, and the four boys found themselves looking into the muzzles of the guns in the hands of the savages.
