Shoshawnee lifted his hand.

"Up there, presently," he said, "you will see the Wolf-trail. It is along the Wolf-trail that you travel to reach them. The Wolf-trail is worn across the heavens by the moccasins of the dead."

"Is the hunting better there than it is here?" Shasta asked. "Is there more game?"

"It is not better hunting," Shoshawnee said, correcting him. "It is happier. The dead are full of happiness as they follow along the trail."

After that there was a long silence, as Shasta kept looking at the sky to watch for the beginning of the Wolf-trail, when the stars should appear. But before that happened Shoshawnee spoke again. This time he spoke quickly, using many words. He spoke so rapidly, and the words followed each other so fast, that at first Shasta could not understand. All he gathered was that danger was in the air, some great danger which as yet you could not see, but which was approaching, always drawing steadily nearer out there on the prairies, and which might arrive before you knew. Then, as Shoshawnee went on, the danger took a shape. It was the shape of Indians on the warpath—Assiniboines that came with deadly cunning and purpose, travelling like wolves along the prairie hollows.

Shasta sent his eyes far across the darkening plains, where all things were becoming shadowy and remote, and where even the great herd of buffalo beyond the Saska was no longer visible. How far away the Assiniboines might be he could not guess. Nor could Shoshawnee tell him, when he asked. All Shoshawnee knew was that they were coming, and that when he had finished his medicine-making he would go and warn the tribe. Of one thing only was he certain, and that was, that however near they might be they would not attack at night. The Assiniboines were fierce and cruel but they dreaded the darkness, because they declared that the ghosts of their enemies and many evil spirits were abroad. Their favourite hour of attack was just at daybreak when the first glimmer of dawn was mingling with the mist.

When the last light of sunset had faded from the sky, and the prairies were wholly dark, Shasta and Shoshawnee returned to the camp.

Shasta lay awake long that night, listening and wondering. The words of the old medicine-man kept walking in his head. Sometimes it was of the buffaloes he thought, with their pasture that lay out into the sunset and was a-shimmer with the long lights of the west; and sometimes of that mysterious danger that crept nearer and nearer, and gave no sign of its approach. And then the butterfly, the sleep-bringer, flitted across his eyelids and he slept.

It was the western lark-sparrow that woke him in the morning, singing loud and clear upon the lodge-pole over his head. And when he saw the sunlight clear through the painted wall of the tepee, and heard the cheerful morning stir of the camp, it seemed impossible that danger should be afoot in that tremendous peace. Yet, as the day wore on and evening drew near, he felt the same foreboding at his heart as when Shoshawnee had spoken to him of danger when they sat on the lookout bluff.

As for Shoshawnee, he sat there all day, without food or drink, gazing steadily across the prairies and chanting the old medicine chants of the tribe. When evening fell Shoshawnee returned. He had already warned the tribe of what he feared, and Big Eagle had given orders that all was to be in readiness in case of an attack. Scouts had been sent out, but had returned at sundown, saying that no signs of hostile Indians had been seen.
