"Arrow?"
"Sure. Missed ye when ye took that flop, and stuck in the tree over yonder. What'd ye rush the guy for, anyways? Whyn't ye drill him from where ye was?"
In the reaction from his sudden fright Tim was as wrathfully ready to "bawl out" his captain as if he were some raw rookie. McKay, with a cool smile, explained his abrupt action, meanwhile reconnoitering the dimness for any further sign of the vanished assailant. None showed.
While Tim stood vigilant guard the other two stooped and moved around the base of the tree, narrowly examining the ground. Beyond it they paused at one spot, fingered the soil lightly, and lit a match or two.
"No ghost," said Knowlton. "Barefoot man. Didn't leave much trace, but enough to show he was here. Let's look at that arrow."
Back to the hollow tree they went, retrieving McKay's pistol on the way. About a yard above the earth a long shaft projected from the bark. Knowlton reached for it, but McKay held him back and drew it out.
"M-hm! Thought so!" he muttered. "Poisoned."
"Oof! Nice, gentle sort of a cuss," rumbled Tim. "That smear on the point—is that poison?"
"Poison. Quickest and deadliest kind of poison. Mixes instantly with blood. Paralysis—convulsions—death. The least scratch and you're gone. Wicked head on this thing, too: looks like a piece of serrated bone. See all those little barbs along the edges? War arrow, all right."
"Meanin' that we'll be jumped pretty soon by more Injuns. If that guy's on the warpath he ain't alone."
