battlefields of the great civil war, where he had been mentioned specially in orders more than once for courage and intelligence, but here he felt himself in the presence of an alarming puzzle. His mission was to be both diplomat and warrior. He was not sure where the duties of diplomat ceased and those of warrior began.

Meanwhile his protagonist, the Indian chief, had no doubt at all about his own intentions and was stating them with a clearness that could not be mistaken. Captain Kenyon continued to switch his boot uneasily and to take a nervous step back and forth, his figure outlined against the fire. Young Clarke felt a certain sympathy for him, placed without experience in a situation so delicate and so full of peril.

The Ogalala stopped talking and looked straight at the officer, standing erect and waiting, as if he expected a quick answer, and only the kind of answer, too, that he wished. Meanwhile there was silence, save for an occasional crackle of burning wood.

Both young Clarke and the hunter, Boyd, felt with all the intensity of conviction that it was a moment charged with fate. The white people had come from the Atlantic to the great plains, but the mighty Sioux nation now barred the way to the whole Northwest, it was not a barrier to be passed easily. Will, as he said, understood, too, the feelings of Mahpeyalute. Had he been an Ogalala like the chief he would have felt as the Ogalala felt. Yet, whatever happened, he and Boyd meant to go on, because they had a mission that was calling them all the time.

The Captain at last said a few words, and Red Cloud, who had been motionless while he waited, took from under his blanket a pipe with a long curved stem. Will was surprised. He knew something of Indian custom, but he had not thought that the fierce Ogalala chief would propose to smoke a pipe of peace at a time like the present. Nor was any such thought in the mind of Red Cloud. Instead, he suddenly struck the stem of the pipe across the trunk of a sapling, breaking it in two, and as the bowl fell upon the ground he put his foot upon it, shattering it. Then, raising his hand in a salute to Captain Kenyon, he turned upon his heel and walked away, all the other Indians following him without a word. At the edge of the thin forest they mounted their ponies and rode out of sight in the darkness.

Captain Kenyon stood by the fire, gazing thoughtfully into the dying coals, while the troopers, directed by the sergeants, were spreading the blankets for the night. Toward the north, where the foothills showed dimly, a wolf howled. The lone, sinister note seemed to arouse the officer, who gave some orders to the men and then turned to meet the hunter and the lad.

"I've no doubt you surmised what the Indian meant," he said to Boyd.

"I fancy he was telling you all the trails through the Northwest were closed to the white people," said the hunter.

"Yes, that was it, and his warning applied to hunters, scouts and gold-seekers as well as settlers. He told me that the Sioux would not have their hunting grounds invaded, and the buffalo herds on which they live destroyed."

"What he told you, Captain, is in the heart of every warrior of their nation. The Northern Cheyennes, a numerous and warlike tribe, feel the same way, also. The army detachments are too few and too scattered to hold back the white people, and a great and terrible war is coming."

"At least," said Captain Kenyon, "I must do my duty as far as I may. I can't permit you and your young friend, Mr. Clarke, to go into the Sioux country. The Indian chief, Red Cloud, showed himself to be a fierce and resolute man and you would soon lose your lives."

Will's face fell, but the hunter merely shrugged his great shoulders.

"But you'll permit us to pass the night in your camp, Captain?" he said.

"Of course. Gladly. You're welcome to what we have. I'd not drive anybody away from company and fire."

"We thank you, Captain Kenyon," said Will warmly. "It's a genuine pleasure to us to be the guests of the army when we're surrounded by such a wilderness."

Their horses were tethered nearby with those of the troop, and securing their blankets from their packs they spread them on dead leaves near the fire.

"You'll take breakfast with us in the morning," said Captain Kenyon hospitably, "and then I'll decide which way to go, and what task we're to undertake. I wish you'd join us as scout, hunter and guide, Mr. Boyd. We need wisdom like yours, and Mr. Clarke could help us, too."

"I've been independent too long," replied the hunter lightly. "I've wandered mountain and plain so many years at my own free will that I couldn't let myself be bound now by military rules. But I thank you for the compliment, just the same, Captain Kenyon."

He and Will Clarke lay down side by side with their feet to the fire, their blankets folded about them rather closely, as the air, when the night advanced and the coals died completely, was sure to grow cold. Will was troubled, as he was extremely anxious to go on at once, but he reflected that Jim Boyd was one of the greatest of all frontiersmen and he would be almost sure to find a way. Summoning his will, he dismissed anxiety from his mind and lay quite still, seeking sleep.

The camp was now quiet and the fire was sinking rapidly. Sentinels walked on every side, but Will could not see them from where he lay. A light wind blowing down from the mountains moaned through the thin forest. Clouds came up from the west, blotting out the horizon and making the sky a curving dome of blackness. Young William Clarke felt that it was good to have comrades in the immense desolation, and it strengthened his spirit to see the soldiers rolled in their blankets, their feet to the dying coals.

Yet his trouble about the future came back. He and Boyd were in truth and reality prisoners. Captain Kenyon was friendly and kind, but he would not let them go on, because the Sioux and Cheyennes had barred all the trails and the formidable Red Cloud had given a warning that could not be ignored. Making another effort, he dismissed the thought a second time and just as the last coals were fading into the common blackness he fell asleep.

He was awakened late in the night by a hand pushing gently but insistently against his shoulder. He was about to sit up abruptly, but the voice of Boyd whispered in his ear:

"Be very careful! Make no noise! Release yourself from your blanket and then do what I say!"

The hand fell away from his shoulder, and, moving his head a little, Clarke looked carefully over the camp. The coals where the fire had been were cold and dead, and no light shone there. The figures of the sleeping soldiers were dim in the dusk, but evidently they slept soundly, as not one of them stirred. He heard the regular breathing of those nearest to him, and the light step of the sentinel just beyond a clump of dwarf pines.

"Sit up now," whispered Boyd, "and when the sentinel passes a little farther away we'll creep from the camp. Be sure you don't step on a stick or trip over anything. Keep close behind me. The night's as black as pitch, and it's our one chance to escape from friends who are too hospitable."

Will saw the hunter slowly rise to a stooping position, and he did likewise. Then when the sound of the sentinel's step was lost at the far end of his beat, Boyd walked swiftly away from the camp and Will followed on his trail. The lad glanced back once, and saw that the dim figures by the dead fire did not stir. Weary and with the soothing wind blowing over them, they slept heavily. It was evident that the two who would go their own way had nothing to fear from them. There was now no bar to their departure, save the unhappy chance
