sixties a trail led from the broad Missouri, swirling yellow and turgid between its green-groved borders, for miles and miles out upon the grassy Nebraska plains, turning westward over the undulating prairie, with its swales and billows and long, winding lines of cottonwoods, to a slow, vast heave of rising ground—Wyoming—where the herds of buffalo grazed and the wolf was lord and the camp-fire of the trapper sent up its curling blue smoke from beside some lonely stream; on and on over the barren lands of eternal monotony, all so gray and wide and solemn and silent under the endless sky; on, ever on, up to the bleak, black hills and into the waterless gullies and through the rocky gorges where the deer browsed and the savage lurked; then slowly rising to the pass between the great bold peaks, and across the windy uplands into Utah, with its verdant valleys, green as emeralds, and its haze-filled canons and wonderful wind-worn cliffs and walls, and its pale salt lakes, veiled in the shadows of stark and lofty rocks, dim, lilac-colored, austere, and isolated; ever onward across Nevada, and ever westward, up from desert to mountain, up into California, where the white streams rushed and roared and the stately pines towered, and seen from craggy heights, deep down, the little blue lakes gleamed like gems; finally sloping to the great descent, where the mountain world ceased and where, out beyond the golden land, asleep and peaceful, stretched the illimitable Pacific, vague and grand beneath the setting sun.

Deep in the Wyoming hills lay a valley watered by a stream that ran down from Cheyenne Pass; a band of Sioux Indians had an encampment there. Viewed from the summit of a grassy ridge, the scene was colorful and idle and quiet, in keeping with the lonely, beautiful valley. Cottonwoods and willows showed a bright green; the course of the stream was marked in dark where the water ran, and light where the sand had bleached; brown and black dots scattered over the valley were in reality grazing horses; lodge-pole tents gleamed white in the sun, and tiny bits of red stood out against the white; lazy wreaths of blue smoke rose upward.

The Wyoming hills were split by many such valleys and many such bare, grassy ridges sloped up toward the mountains. Upon the side of one ridge, the highest, there stood a solitary mustang, haltered with a lasso. He was a ragged, shaggy, wild beast, and there was no saddle or bridle on him, nothing but the halter. He was not grazing, although the bleached white grass grew long and thick under his hoofs. He looked up the slope, in a direction indicated by his pointing ears, and watched a wavering movement of the long grass.

It was wild up on that ridge, bare of everything except grass, and the strange wavering had a nameless wildness in its motion. No stealthy animal accounted for that trembling—that forward undulating quiver. It wavered on to the summit of the ridge.

What a wide and wonderful prospect opened up to view from this lofty point! Ridge after ridge sloped up to the Wyoming hills, and these in turn raised their bleak, dark heads toward the mountains, looming pale and gray, with caps of snow, in the distance. Out beyond the ridges, indistinct in the glare, stretched an illimitable expanse, gray and dull—that was the prairie-land. An eagle, lord of all he surveyed, sailed round and round in the sky.

Below this grassy summit yawned a valley, narrow and long, losing itself by turns to distant east and west; and through it ran a faint, white, winding line which was the old St. Vrain and Laramie Trail.

There came a moment when the wavering in the grass ceased on the extreme edge of the slope. Then it parted to disclose the hideous visage of a Sioux Indian in war paint. His dark, piercing, malignant glance was fixed upon the St. Vrain and Laramie Trail. His half-naked body rested at ease; a rifle lay under his hand.

There he watched while the hours passed. The sun moved on in its course until it tipped the peaks with rose. Far down the valley black and white objects appeared, crawling round the bend. The Indian gave an almost imperceptible start, but there was no change in his expression. He watched as before.

These moving objects grew to be oxen and prairie-schooners—a small caravan traveling east. It wound down the trail and halted in a circle on the bank of a stream.

The Indian scout slid backward, and the parted grass, slowly closing, hid from his dark gaze the camp scene below. He wormed his way back well out of sight; then rising, he ran over the summit of the ridge to leap upon his mustang and ride wildly down the slope.

Bill Horn, leader of that caravan, had a large amount of gold which he was taking back East. No one in his party, except a girl, knew that he had the fortune.

Horn had gone West at the beginning of the gold strikes, but it was not until '53 that any success attended his labors. Later he struck it rich, and in 1865, as soon as the snow melted on the mountain passes, he got together a party of men and several women and left Sacramento. He was a burly miner, bearded and uncouth, of rough speech and taciturn nature, and absolutely fearless.

At Ogden, Utah, he had been advised not to attempt to cross the Wyoming hills with so small a party, for the Sioux Indians had gone on the war-path.

Horn was leading his own caravan and finding for himself the trail that wound slowly eastward. He did not have a scout or hunter with him. Eastward-traveling caravans were wont to be small and poorly outfitted, for only the homesick, the failures, the wanderers, and the lawless turned their faces from the Golden State. At the start Horn had eleven men, three women, and the girl. On the way he had killed one of the men; and another, together with his wife, had yielded to persuasion of friends at Ogden and had left the party. So when Horn halted for camp one afternoon in a beautiful valley in the Wyoming hills there were only nine men with him.

On a long journey through wild country strangers grow close together or far apart. Bill Horn did not think much of the men who had accepted the chance he offered them, and daily he grew more aloof. They were not a responsible crowd, and the best he could get out of them was the driving of oxen and camp chores indifferently done. He had to kill the meat and find the water and keep the watch. Upon entering the Wyoming hills region Horn showed a restlessness and hurry and anxiety. This in no wise affected the others. They continued to be aimless and careless as men who had little to look forward to.

This beautiful valley offered everything desirable for a camp site except natural cover or protection in case of attack. But Horn had to take the risk. The oxen were tired, the wagons had to be greased, and it was needful to kill meat. Here was an abundance of grass, a clear brook, wood for camp-fires, and sign of game on all sides.

"Haul round—make a circle!" Horn ordered the drivers of the oxen.

This was the first time he had given this particular order, and the men guffawed or grinned as they hauled the great, clumsy prairie-schooners into a circle. The oxen were unhitched; the camp duffle piled out; the ring of axes broke the stillness; fires were started.

Horn took his rifle and strode away up the brook to disappear in the green brush of a ravine.

It was early in the evening, with the sun not yet out of sight behind a lofty ridge that topped the valley slope. High grass, bleached white, shone brightly on the summit. Soon several columns of blue smoke curled lazily aloft until, catching the wind high up, they were swept away. Meanwhile the men talked at their tasks.

"Say, pard, did you come along this here Laramie Trail goin' West?" asked one.

"Nope. I hit the Santa Fe
