He said, with elaborate carelessness:

"It exists among the Senecas."

"And apparently among the Wyandottes."

"Apparently."

I said in a low voice:

"Yonder Huron differs from any Indian I ever knew. Yet, in what he differs I can not say. I have seen Senecas like him physically. But Senecas and Hurons not only fought but interbred. This Wyandotte may have Seneca blood in him."

The Sagamore made no answer, and after a moment I said:

"Why not confess, Mayaro, that you also have been perplexed concerning this stranger from Fort Pitt? Why not admit that from the moment he joined us you have had your eye on him--have been furtively studying him?"

"Mayaro has two eyes. For what are they unless to observe?"

"And what has my brother observed?"

"That no two people are perfectly similar," he said blandly.

"Very well," I said, vexed, but quite aware that no questions of mine could force the Sagamore to speak unless he was entirely ready. "I suppose that there exist no real grounds on which to suspect this Wyandotte. But you know as well as do I that he crossed not the river with the others when they did to death that wretched St. Regis hunter.

Also, that there are Wyandottes in our service at Fortress Pitt, I did not know before."

I waited a moment, but the Mohican said nothing, and I saw his eyes, veiled like a dreaming bird of prey, so immersed did he seem to be in his own and secret reflections.

Presently I rose, went down to the fire, felt with my fingers among the ashes to be certain no living spark remained, chatted a moment with the Oneida youth, praising him till under all his modesty I saw he was like to burst with pride; then gave the signal for departure.

"Nevertheless," I added, addressing them all, "this is not a scalping party; it is the six eyes of an army spying out a way through this wilderness, so that our wagons, artillery, horses, and cattle may pa.s.s in safety to Tioga Point.

"Let the Sagamore strike each tree to be marked, as he leads forward.

Let the Mole repeat the blow unless otherwise checked. Then shall the Oneida, Grey-Feather, mark clearly the tree so doubly designated. The Oneida, Tahoontowhee, covers our right flank, marching abreast of the Mohican; the Wyandotte, Black-Snake, covers our left flank, keeping the river bank in view. March!"

All that afternoon we moved along south and west, keeping in touch with the Susquehanna, which here is called Oak Creek, though it is the self-same stream. And we scouted the river region thoroughly, routing out nothing save startled deer that bounded from their balsam beds and went off crashing through the osiers, or a band of wild turkeys that, bewildered, ran headlong among us so that Tahoontowhee knocked over two with his rifle b.u.t.t, and, slinging them to his shoulders, went forward buried in plumage like same monstrous feathered goblin of the forest.

The sun was now dropping into the West; the woods on our right had darkened; on our left a pink light netted the river ripples. Filing in perfect silence, save for the light sound of a hatchet and the slithering of sappy bark, I had noticed, or thought I noticed, that the progress of the Wyandotte was less quiet than ours, where he ranged our left flank, supposedly keeping within the forest shadow.

Once or twice I thought I heard a small stone fall to the willow gully, as though accidentally dislodged by his swiftly pa.s.sing moccasins.

Once, at any rate, I caught the glimmer of the sun striking some bit of metal on him, where he had incautiously ranged outside the protecting shadow belt.

That these things were purely accidental I felt sure, yet I did not care to have them repeated. And for a long while there was neither sound nor sun-glitter from him. Then, without even a glance or a word for me, the Mohican quietly dropped back from the lead, waited until the last Oneida had pa.s.sed, and moved swiftly on a diagonal course to the left, which brought him in the tracks of the Wyandotte.

He continued on that course for a while, I taking his place in the lead, and the Wyandotte unconscious that he was followed. Then the Sagamore came gliding into our file again, and as he pa.s.sed me to resume his lead, he whispered:

"Halt, and return along the bank. The Black-Snake has overrun a ford where there are signs for my brother to read and consider."

I turned sharply and lifted my hand; and as the file halted I caught a glimpse of the Oneida, Tahoontowhee, on our right, and motioned him to cross, head the Wyandotte, and return with him. And when in a few moments he came toward us, followed by the Huron, I said, addressing them all:

"There should be a ford hereabouts, if I am not badly mistaken, and I think we have accidentally overrun it. Did you see nothing that might indicate it, Black-Snake, my brother?"

There was a furtive flicker of the Wyandotte's eyes which seemed to include everybody before him, then he said very coolly that he had seen no riffle that might indicate shallow water, but that there was a ford not far below, and we ought to strike it before sunset.

"Halt here," said I, pretending to remain still unconvinced. "Sagamore, do you come with me a rod or so upstream."

"There is no ford within a rod or two," said the Wyandotte stolidly.

And, after we had left the others, the Mohican murmured, as we hastened on:

"No, not with one rod or two, but the third rod marks it."

Presently, speeding under the outer fringe of trees, I caught sight of a thin line across the water, slanting from sh.o.r.e to sh.o.r.e--not a ripple, but as though the edge of an invisible reef slightly affected the smooth-flowing, gla.s.sy surface of the stream.

"He might have overlooked that," said I.

The Sagamore's visage became very smooth; and we climbed down among the willows toward the sand below, and there the Mohican dropped on his hands and knees.

Directly under his eyes I saw the faint print of a moccasin. Startled, I said nothing; the Mohican studied the print for a few moments, then, crouching, crept forward among the sand-willows. I followed; and at long intervals I could make out the string of moccasin tracks, still visible in the loose, dry sand.

"Could it be the St. Regis?" I whispered. "He may have been here spearing fish. These tracks are not new.... And the Wyandotte might have overlooked these, too."

"Maybe St. Regis," he said.

We had now crept nearly to the edge of the water, the dry and scarcely discernible tracks leading us. But they were no fresher in the damp sand. However, the Mohican did not seem satisfied, so we pulled off our thigh-moccasins and waded out.

Although the water looked deep enough along the unseen reef, yet we found nowhere more than four feet, and so crossed to the other side.

But before I could set foot on the shelving sand the Mohican pulled me back into the water and pointed. There was no doubting the sign we looked upon. A canoe had landed here within an hour, had been pushed off again with a paddle without anybody landing. It was as plain as the nose on your face.

Which way had it gone, upstream or down? If it had gone upstream, the Wyandotte must have seen it and pa.s.sed it without reporting it. In other words, he was a traitor. But if the canoe had gone downstream from this spot, or from some spot on the left bank a little above it, there was nothing to prove that the Wyandotte had seen it. In fact, there was every probability that he had not seen it at all. And I said as much to the Sagamore.

"Maybe," he replied calmly.

We now cautiously recrossed the stream, scarcely liking our exposed position, but there was no help for it. After we had dressed, I marked the trees from the ford across the old path, which was visible here, and so through to our main, spotted trail; the Mohican peeled a square of bark, I wiped the white spot dry, and wrote with my wood-coal the depth of water at the crossing; then we moved swiftly forward to join the halted scouts.

Mayaro said to me: "We have discovered old moccasin tracks, but no ford and no canoe marks. It is not necessary for the Black-Snake to know."

"Very well," said I calmly. "Do you suspect him!"

"Maybe. Maybe not. But--he once wore his hair in a ridge."

"What!"

"I looked down on him while he ate fish at the St. Regis fire. He has not shaved his head since two weeks. There is a thin line dividing his head, where the hairs at their roots are bent backward. Much oil and brushing make hairs grow that way."

"But--what Indians wear their hair that way--like the curved ridge on a dragoon's helmet?"

"The Eries."

I stared at him without comprehension, for I knew an Erie scalp when I saw one.
