They lay close and Robert was very thankful now for the logs they had
dragged up from the water, as they afforded almost complete shelter. The
crouching warrior farther up the stream fired, and his bullet struck the
hollow above their heads.

"A better aim than they often show," said Willet.

More shots were fired, and one buried itself in the log in front of
Robert. He heard the thud made by the bullet as it entered, and once
more he was thankful for their rude breastwork. But it was the only one
that struck so close and presently the savages ceased their fire,
although the besieged three were still able to see them in the brilliant
moonlight among the bowlders.

"They're getting a bit too insolent," said the hunter. "Maybe they think
it's a shorter distance from them to us than it is from us to them, and
that our bullets would drop before they got to 'em. I think, Tayoga,
I'll prove that it's not so."

"Choose the man at the edge of the water," said Tayoga. "He has fired
three shots at us, and we should give him at least one in return."

"I'll pay the debt, Tayoga."

Robert saw the warrior, his head and shoulders and painted chest
appearing above the stone. The distance was great for accuracy, but the
light was brilliant, and the rifle of the hunter rose to his shoulder.
The muzzle bore directly upon the naked chest, and when Willet pulled
the trigger a stream of fire spurted from the weapon.
