"What! in camp?"

"Hiding with the Sioux. Two Knives heard about it." (Two Knives was a friendly Indian.) "He's laying for me," Cutler added.

"You've seen him?"

"No. I want to quit my job and go after him."

"Nonsense!" said Powell.

"You can't, Cutler," said Balwin. "I can't spare you."

"You'll be having to fill my place, then, I guess."

"You mean to go without permission?" said Powell, sternly.

"Lord, no! He'll shoot me. That's all."

The two lieutenants pondered.

"And it's to-day," continued Cutler, plaintively, "that he should be gettin' hanged in Cheyenne."

Still the lieutenants pondered, while the wagon-master inspected a photograph of Marie Rose as Marguerite.

"I have it!" exclaimed Powell. "Let's kill him."

"How about the commanding officer?"

"He'd back us--but we'll tell him afterwards. Cutler, can you find Toussaint?"

"If I get the time."

"Very well, you're off duty till you do. Then report to me at once."

Just after guard-mounting two days later, Cutler came in without knocking. Toussaint was found. He was down on the river now, beyond the stockade. In ten minutes the wagon-master and the two lieutenants were rattling down to the agency in an ambulance, behind four tall blue government mules. These were handily driven by a seventeen-year-old boy whom Balwin had picked up, liking his sterling American ways. He had come West to be a cow-boy, but a chance of helping to impress Red Cloud had seemed still dearer to his heart. They drew up at the agency store, and all went in, leaving the boy nearly out of his mind with curiosity, and pretending to be absorbed with the reins. Presently they came out, Balwin with field-glasses.

"Now," said he, "where?"

"You see the stockade, sir?"

"Well?" said Powell, sticking his chin on Cutler's shoulder to look along his arm as he pouted. But the scout proposed to be deliberate.

"Now the gate of the stockade is this way, ain't it?"

"Well, well?"

"You start there and follow the fence to the corner--the left corner, towards the river. Then you follow the side that's nearest the river down to the other corner. Now that corner is about a hundred yards from the bank. You take a bee-line to the bank and go down stream, maybe thirty yards. No; it'll be forty yards, I guess. There's a lone pine-tree right agin the edge." The wagon-master stopped.

"I see all that," said Lieutenant Balwin, screwing the field-glasses.

"There's a buck and a squaw lying under the tree."

"Naw, sir," drawled Cutler, "that ain't no buck. That's him lying in his Injun blanket and chinnin' a squaw."

"Why, that man's an Indian, Cutler. I tell you I can see his braids."

"Oh, he's rigged up Injun fashion, fust rate, sir. But them braids of his ain't his'n. False hair."

The lieutenants passed each other the fieldglasses three times, and glared at the lone pine and the two figures in blankets. The boy on the ambulance was unable to pretend any longer, and leaned off his seat till he nearly fell.

"Well," said Balwin, "I never saw anything look more like a buck Sioux.

Look at his paint. Take the glasses yourself, Cutler."

But Cutler refused. "He's like an Injun," he said. "But that's just what he wants to be." The scout's conviction bore down their doubt.

They were persuaded. "You can't come with us, Cutler," said Powell. "You must wait for us here."

"I know, sir; he'd spot us, sure. But it ain't right. I started this whole business with my poker scheme at that cabin, and I ought to stay with it clear through."

The officers went into the agency store and took down two rifles hanging at the entrance, always ready for use. "We're going to kill a man," they explained, and the owner was entirely satisfied. They left the rueful Cutler inside, and proceeded to the gate of the stockade, turning there to the right, away from the river, and following the paling round the corner down to the farther right-hand corner. Looking from behind it, the lone pine-tree stood near, and plain against the sky. The striped figures lay still in their blankets, talking, with their faces to the river. Here and there across the stream the smoke-stained peak of a tepee showed among the green leaves.

"Did you ever see a more genuine Indian?" inquired Baldwin.

"We must let her rip now, anyhow," said Powell, and they stepped out into the open. They walked towards the pine till it was a hundred yards from them, and the two beneath it lay talking all the while. Balwin covered the man with his rifle and called. The man turned his head, and seeing the rifle, sat up in his blanket. The squaw sat up also. Again the officer called, keeping his rifle steadily pointed, and the man dived like a frog over the bank. Like magic his blanket had left his limbs and painted body naked, except for the breech-clout. Balwin's tardy bullet threw earth over the squaw, who went flapping and screeching down the river. Balwin and Powell ran to the edge, which dropped six abrupt feet of clay to a trail, then shelved into the swift little stream. The red figure was making up the trail to the foot-bridge that led to the Indian houses, and both officers fired. The man continued his limber flight, and they jumped down and followed, firing.

They heard a yell on the plain above, and an answer to it, and then confused yells above and below, gathering all the while. The figure ran on above the river trail below the bank, and their bullets whizzed after it.

"Indian!" asserted Balwin, panting.

"Ran away, though," said Powell.

"So'd you run. Think any Sioux'd stay when an army officer comes gunning for him?"

"Shoot!" said Powell. "'S getting near bridge," and they went on, running and firing. The yells all over the plain were thickening. The air seemed like a substance of solid flashing sound. The naked runner came round the river curve into view of the people at the agency store.

"Where's a rifle?" said Cutler to the agent.

"Officers got 'em," the agent explained.

"Well, I can't stand this," said the scout, and away he went.

"That man's crazy," said the agent.

"You bet he ain't!" remarked the ambulance boy.

Cutler was much nearer to the bridge than was the man in the breech-clout, and reaching the bank, he took half a minute's keen pleasure in watching the race come up the trail. When the figure was within ten yards Cutler slowly drew an ivory-handled pistol. The lieutenants below saw the man leap to the middle of the bridge, sway suddenly with arms thrown up, and topple into White River. The current swept the body down, and as it came it alternately lifted and turned and sank as the stream played with it. Sometimes it struck submerged stumps or shallows, and bounded half out of water, then drew under with nothing but the back of the head in sight, turning round and round. The din of Indians increased, and from the tepees in the cottonwoods the red Sioux began to boil, swarming on the opposite bank, but uncertain what had happened. The man rolling in the water was close to the officers.

"It's not our man," said Balwin. "Did you or I hit him?"

"We're gone, anyhow," said Powell, quietly. "Look!"
