Had the wanderer remained awake for another half-hour a strange sight would have met his eyes. Far away on the extreme verge of the alkali plain there rose up a little spray of dust, very slight at first, and hardly to be distinguished from the mists of the distance, but gradually growing higher and broader until it formed a solid, well-defined cloud. This cloud continued to increase in size until it became evident that it could only be raised by a great multitude of moving creatures. In more fertile spots the observer would have come to the conclusion that one of those great herds of bisons which graze upon the prairie land was approaching him. This was obviously impossible in these arid wilds. As the whirl of dust drew nearer to the solitary bluff upon which the two castaways were reposing, the canvas-covered tilts of wagons and the figures of armed horsemen began to show up through the haze, and the apparition revealed itself as being a great caravan upon its journey for the West. But what a caravan! When the head of it had reached the base of the mountains, the rear was not yet visible on the horizon. Right across the enormous plain stretched the straggling array, wagons and carts, men on horseback, and men on foot. Innumerable women who staggered along under burdens, and children who toddled beside the wagons or peeped out from under the white coverings. This was evidently no ordinary party of immigrants, but rather some nomad people who had been compelled from stress of circumstances to seek themselves a new country. There rose through the clear air a confused clattering and rumbling from this great mass of humanity, with the creaking of wheels and the neighing of horses. Loud as it was, it was not sufficient to rouse the two tired wayfarers above them.

At the head of the column there rode a score or more of grave, iron-faced men, clad in sombre homespun garments and armed with rifles. On reaching the base of the bluff they halted, and held a short council among themselves.

“The wells are to the right, my brothers,” said one, a hard-lipped, clean-shaven man with grizzly hair.

“To the right of the Sierra Blanco - so we shall reach the Rio Grande,” said another.

“Fear not for water,” cried a third. “He who could draw it from the rocks will not now abandon His own chosen people.”

“Amen! amen!” responded the whole party.

They were about to resume their journey when one of the youngest and keenest-eyed uttered an exclamation and pointed up at the rugged crag above them. From its summit there fluttered a little wisp of pink, showing up hard and bright against the gray rocks behind. At the sight there was a general reining up of horses and unslinging of guns, while fresh horsemen came galloping up to reinforce the vanguard. The word “Redskins” was on every lip.

“There can’t be any number of Injuns here,” said the elderly man who appeared to be in command. “We have passed the Pawnees, and there are no other tribes until we cross the great mountains.”

“Shall I go forward and see, Brother Stangerson?” asked one of the band.

“And I,” “And I,” cried a dozen voices.

“Leave your horses below and we will await you here,” the elder answered. In a moment the young fellows had dismounted, fastened their horses, and were ascending the precipitous slope which led up to the object which had excited their curiosity. They advanced rapidly and noiselessly, with the confidence and dexterity of practised scouts. The watchers from the plain below could see them flit from rock to rock until their figures stood out against the sky-line. The young man who had first given the alarm was leading them. Suddenly his followers saw him throw up his hands, as though overcome with astonishment, and on joining him they were affected in the same way by the sight which met their eyes.
