"Saddle up, men!" rang the order across the stream. And then while strong arms lifted and bore the wounded herdsman to the porch, Dean turned to the wailing mistress, who, white-faced and terror-stricken, was wringing her hands and moaning and running wildly up and down the walk and calling for some one to go and save her husband. Dean almost bore her to a chair and bade her fear nothing. He and his men would lose not a moment. On the floor at her feet lay the little card photograph, and Dean, hardly thinking what he did, stooped, picked it up and placed it in the pocket of his hunting shirt, just as the trumpeter on his plunging gray reached the gate, Dean's big, handsome charger trotting swiftly alongside. In an instant the lieutenant was in saddle, in another second a trooper galloped up with his belt and carbine. Already the men were leading into line across the stream, and, bidding the trumpeter tell Sergeant Shaughnessy to follow at speed, the young officer struck spur to his horse and, carbine in hand, a single trooper at his heels, away he darted down the valley, "C" Troop, splashing through the ford a moment later, took the direct road past the stockade of the corral, disappeared from sight a moment behind that wooden fortification, and, when next it hove in view, it was galloping front into line far down the Laramie, then once more vanished behind its curtain of dust. "Two miles out there under the butte," was the only indication the young officer had of the scene of the fight, for fight he knew it must be, and even as he went bounding down the valley he recalled the story of the Indian girl, the threats of Burning Star, the vowed vengeance of her brothers. Could it be that, taking advantage of this raid of Red Cloud, far from all the reservations, far from possibility of detection by count of prying agents, the three had induced a gang of daring, devil-may-care young warriors to slip away from the Big Horn with them and, riding stealthily away from the beaten trails, to ford the Platte beyond the ken of watchful eyes at Frayne and sneak through the mountain range to the beautiful, fertile valley beyond, and there lie in wait for Hal Folsom or for those he loved? What was to prevent? Well they knew the exact location of his ranch. They had fished and sported all about it in boy days--days when the soldiers and the Sioux were all good friends, days before the mistaken policy of a post commander had led to an attack upon a peaceful band, and that to the annihilation of the attacking party. From that fatal day of the Grattan massacre ten years before, there had been no real truce with the Sioux, and now was opportunity afforded for a long-plotted revenge. Dean wondered Folsom had not looked for it instead of sleeping in fancied security.
