A dozen Sioux in sight! That was unusual. Ordinarily the Indian keeps in hiding, lurking behind sheltering crests and ridges in the open country, or the trees and underbrush where such cover is possible. A dozen in sight?

"How far ahead, Murray?" asked the captain, as he shook free his rein and started forward at the gallop. "Did you see them yourself?"

"Yes, sir. Most of 'em were bunched by the roadside, jabbing with their lances at something or other. Two or three were closer in. They must ha' been watching us, for they only quit the ridge just before we came up. Then they skedaddled." The vernacular of the civil war days, long since forgotten except about the few Veteran Soldiers' Homes in the East, was still in use at times in regiments like the ——th, which had served the four years through with the Army of the Potomac. Old sergeants give the tone to younger soldiers in all the customs of the service. The captain and the two men now with him had caught up with Field's swift trotting support by this time, and the eyes of the men kindled instantly at sight of their leader speeding easily by, cool, confident and as thoroughly at home as though it were the most ordinary skirmish drill. Those who have never tried it, do not quite realize what it means to ride in closed ranks and compact column, silent and unswerving, straight forward over open fields toward some equally silent crest, that gives no sign of hostile occupancy, and yet may suddenly blaze with vengeful fires and spit its hissing lead into the faces of the advancing force. Even here where the ridge was already gained by two or three of the advance, proving, therefore, that the enemy could not be in possession, men saw by the excitement manifest in the signals of the lieutenant, and indeed of Sergeant Scott, who had spent fifteen years in the ranks, that Indians must be close at hand. The crest was barely five hundred yards in front of the section, and they were still "bunched," a splendid mark if the foe saw fit by sudden dash to regain the ridge and pour in rapid fire from their magazine rifles. Every ward of the nation, as a rule, had his Winchester or Henry,—about a six to one advantage to the red men over the sworn soldier of the government in a short range fight. The lieutenant was a brave lad and all that, and could be relied on to "do his share in a shindy," as the sergeant put it, but when it came to handling the troop to the best advantage, giving them full swing when they met the foe on even terms and a fair field, but holding them clear of possible ambuscade, then "Captain Billy is the boss in the business," was the estimate of his men, and every heart beat higher at sight of him. He would know just what to do for them, and knowing, would do it.

Even as he went loping by Ray had half turned, with something like a smile in his dark eyes and a nod of his curly head to the sergeant commanding, and a gesture of the gauntleted hand,—a horizontal sweep to right and left, twice repeated,—had given the veteran his cue, and with another moment Winsor had the dozen in line at open, yet narrow, intervals, with carbines advanced and ready for business. They saw their captain ride swiftly up the gentle slope until close to the crest, then off he sprang, tossed his reins to the trumpeter and went hurrying afoot to join the lieutenant. They saw him kneeling as though to level his glasses and look fixedly forward; saw Field run back to his horse and mount in a twinkling; saw him whirl about as though coming to place himself at their head, yet rein in at once—his charger's fore feet ploughing the turf at some word from their leader. Field was eager to charge, but Ray had seen for himself and for his men, and Ray said, no. Another moment and all at the front were again in saddle—Field back with the advance, Ray coolly seated astride his pet sorrel,—scouting a second ridge, far to the north, with his glasses, and sending, as before, Scott and his three troopers straight on to the front, and signalling to the flankers to continue the move. Ten seconds' study of the position in the long, wide, shallow depression before him had fathomed the scheme of the savage. The little knot of Indians, jabbering, yelping, prodding and circling about some unseen object on the turf, feigning ignorance of the soldiers' coming, was at the old-time trick to get the foremost troopers to charge and chase, to draw them on in all the dash and excitement of the moment, far ahead—three miles, perhaps—of the main body, and so enable all the lurking band behind that second curtain, the farther ridge, to come swooping down to surround, overwhelm and butcher the luckless few, then be off to safe distance long before the mass of the troop could possibly reach the scene.

"No you don't, Stabber!" laughed Ray, as Field, not a little chagrined, and the dozen at his back, came trotting within hearing distance. "That dodge was bald-headed when I was a baby. Look, Field," he continued. "They were jabbing at nothing there on the prairie. That was a fake captive they were stabbing to death. See them all scooting away now. They'll rally beyond that next ridge, and we'll do a little fooling of our own."

And so, with occasional peep at feathered warriors on the far left flank, and frequent hoverings of small parties on the distant front, Ray's nervy half hundred pushed steadily on. Two experiments had satisfied the Sioux that the captain himself was in command and they had long since recognized the sorrels. They knew of old Ray was not to be caught by time-worn tricks. They had failed to pick off the advance, or the officers, as the troop approached the second ridge. Lame Wolf's big band was coming fast, but only a dozen of his warriors, sent lashing forward, had as yet reached Stabber. The latter was too weak in numbers to think of fighting on even terms, and as Ray seemed determined to come ahead, why not let him? Word was sent to Wolf not to risk showing south of the Elk Tooth spur. There in the breaks and ravines would be a famous place to lie in ambush, leaving to Stabber the duty of drawing the soldiers into the net. So there in the breaks they waited while Ray's long skirmish line easily manœuvred the red sharp-shooters out of their lair on the middle divide. Then, reforming column, the little command bore straight away for the Elk.

But all these diversions took time. Twenty miles to the north of Frayne stretched the bold divide between the Elk Fork, dry as a dead tooth much of the year, and the sandy bottom of the Box Elder. Here and there along the ridge were sudden, moundlike upheavals that gave it a picturesque, castellated effect, for, unlike the general run of the country, the Elk Tooth seemed to have a backbone of rock that shot forth southeastward from the southern limit of the beautiful Big Horn range; and, in two or three places, during some prehistoric convulsion of nature, it had crushed itself out of shape and forced upward a mass of gleaming rock that even in the course of centuries had not been overgrown with grass. "Elk teeth" the Indians had called these odd projections, and one of them, the middle one of the three most prominent, was a landmark seen for many a mile except to the south and west. Eagle Butte was the only point south of the Big Horn and in the valley of the Platte from which it could be seen, and famous were these two points in the old days of the frontier for the beacon fires that burned or the mirror signals that flashed on their summits when the war parties of the Sioux were afield.

It was the sight of puffs of smoke sailing skyward from the crest of the middle tooth that caught Ray's attention the moment he reached the second ridge. A moment more had been devoted to recalling some of his eager men who, from the extreme right of the swinging skirmish line, had broken away in pursuit of certain intentional laggards. Then a dozen of the Indians, finding themselves no longer followed, gathered at comparatively safe distance across the prairie, and, while in eager consultation, found time for taunting, challenging and occasionally firing at the distant and angering troopers, whom Sergeant Scott had sharply ordered back, and Ray, after calm survey of these fellows through his glass, had then levelled it at the trio of buttes along the distant ridge and turned to Field, sitting silent and disappointed by his side.

"There, Field," said the captain. "Take this glass and look at those signal smokes—Stabber has more men now at his call than he had when he started, and more yet are coming. They were just praying you would charge with a handful of men. They would have let you through, then closed around and cut you off. Do you see, boy?"

Field touched his hat brim. "You know them best, sir," was the brief answer. "What I wanted was a chance at those fellows hanging about our front and calling us names."
