In the crisp, chill air of the late autumn morning tiny smokes from the cook-fires sailed straight aloft, melting speedily into the blue. For nearly half a mile along the stream horses and pack-mules were scattered upon the "bench," browsing eagerly on the dew-laden bunch grass. Farther out beyond them on every side, with their campaign hats pulled down over their grim eyebrows and their heads deep in the collars of their cavalry overcoats, the men of the guard still kept vigilant watch. Long years of experience on the Indian frontier had taught their leaders the need of precaution, and the sentries took their cue from the "old hands." By a little camp-fire, booted, spurred, slouch-hatted, like his troopers, and muffled in a light-blue overcoat that could not be told from theirs, the major commanding was giving brief directions to three troopers who stood silently before him, their carbines dangling from their broad shoulder-belts, with the reins of their chargers in hand. Wiry and gaunt were these chargers, wiry and gaunt were the men, for those were days when neither horse nor rider went over-weight on campaign, or came back with a superfluous ounce. But horses and men had stripped for the day's work. Blanket, poncho, and overcoat, saddle-bags, side lines, lariat, and picket-pin—everything, in fact, but themselves, their arms, cartridges, canteens, saddles, saddle-blankets, and bridles—had been left to the pack-train. A good breakfast to start with, a few hardtack and slices of bacon in the breast-pocket of the hunting-shirt, settled the question of subsistence. They were to start at once, deliver those despatches at Niobrara, unless headed off by Indians, long before set of sun, and be back with reply before its rise on the morrow.

Then came the question as to the fate of the poor fellows of Gamble's and the hunters' camp.

"Mr. Willard," said the major to his adjutant, as the couriers mounted and rode away, "send one platoon over to Gamble's camp—it'll take 'em all day—and another back on the trail of the teamsters, and see what they can find of the outfit. They'll have to hunt for it themselves. The hunters say they wouldn't go back for a million apiece."

The adjutant was figuring in his note-book. He closed it, arose at once, and looked about him. Officers and men, the six troops, or companies, of the detachment seemed busy at breakfast. The aroma of soldier coffee floated on the keen morning air, and under the gentle, genial influence of the welcome stimulant men began to thaw out, and presently the firesides were merry with chaff and fun. A curious and sympathetic group, to be sure, hovered about the survivors of the hunters' camp, listening rather doubtfully to their tales, for the tales had taken devious turns under cross-examination. But for the bloody trappings of Pete Gamble's horse, telling mutely of tragedy, the hunters might have met only contempt and scoffing. Indian scares were old as the trails.

"Whose turn is it?" presently questioned the major, as Mr. Willard started away. The adjutant halted and faced about:

"'D' and 'F' troops, sir."

"All right. One officer and twenty men from each will be enough."

And then came striding forward, with quick, elastic steps, a young soldier in dark-blue campaign shirt and riding-breeches, a three weeks' stubble on his clear-cut, sun-burned face, a field-glass slung over one shoulder, a leather-covered note-book tucked away inside his cartridge-belt. No sign of rank was visible about his dress, yet there could be little doubt of it. The major looked up, smiling.

"Fast going for topographical notes yesterday, wasn't it, Mr. Connell?"

"I'm afraid so, sir. Indeed, I'm ashamed to submit them, but I wouldn't have missed this scout for a month's pay, all the same."
