Singular is the picture formed by this lone mound, and the park-like scene that surrounds it--a picture rare as fair. Its very framing is peculiar. The bench of light-reddish sandstone sharply outlined on each edge--the bright green of the sward along its base--and the dark belt of cedars cresting its summit, form, as it were, a double moulding to the frame. Over this can be distinguished the severer outlines of the great Cordilleras; above them, again, the twin cones of the Wa-to-yah; and grandly towering over all, the sharp sky-piercing summit of Pike's Peak. All these forms gleaming in the full light of a noonday sun, with a heaven above them of deep ethereal blue, present a picture that for grandeur and sublimity is not surpassed upon the earth. A long while could we have gazed upon it; but an object, that came at once under our eyes, turned our thoughts into a far different channel. Away up the valley, at its furthest end, appeared a small white spot-- little bigger to our view than the disc of an archer's target. It was of an irregular roundish form; and on both sides of it were other, shapes--smaller and of darker hue. We had no difficulty in making out what these appearances were: the white object was the tilt of a waggon: the dark forms around it were those of men--mounted and afoot! It must have been the last waggon of the train: since no other could be seen; and as it appeared at the very end of the valley--in the angle formed by the convergence of the cliffs--we concluded that there the canon opened into which the rest had entered. Whether the waggon seen was moving onward, we did not stay to determine. The caravan was in sight; and this, acting upon us like an electric influence, impelled us to hasten forward. Calling to our companions to advance, we remounted our horses, rode out of the gorge, and kept on up the valley. We no longer observed the slightest caution. The caravan was before our eyes; and there could be no doubt that, in a couple of hours, we should be able to come up with it. As to danger, we no longer thought of such a thing. Indians would scarcely be so daring as to assail us within sight of the train? Had it been night, we might have reasoned differently; but, under the broad light of day, we could not imagine there was the slightest prospect of danger. We resolved, therefore, to ride direct for the waggons, without making halt.
