It was a delicious morning in early May, and the sun was at his back, its warm rays falling upon him with affectionate caress. But the lad was plainly oblivious of his immediate surroundings; in spirit he had followed the leading of his eyes a league or more to the westward, where a mass of indefinable shadow bulked hugely upon the horizon line. Indefinable, in that it was neither forest nor mountain nor yet an atmospheric illusion produced by the presence of watery vapor. It did not change in density as does the true cloud; for all of its mistiness of outline there was an impression of solidity about its deeper shadows, something that the wind could not lift nor the light pierce. A mystery, and the boy devoured it with his eyes, his head bent forward and his shoulders held tensely. The place was a rocky point of land jutting forth into a reef-strewn tideway. The forest came down close to the strip of beach, but there was comparatively little underwood, and the grass, growing up to the very roots of the trees, gave to the glade an appearance almost parklike. There was no house in sight, not even the thin, blue curl of a smoking hearth to proclaim the neighborhood of man. Yet the sign of human handicraft was not wholly wanting; through the tree trunks, at perhaps a hundred yards away, appeared the line of a timber stockade--enormous palisades, composed of twelve-foot ash and hickory poles, set in a double row and bound together by lengths of copper wire. It was to be further observed that the timbers had been stripped of their bark and the knots smoothed down so as to afford no coigne of vantage to even a naked foot. Add, again, that the poles had been charred and sharpened at the top, and it will be understood that the barrier was a formidable one against any assault short of artillery. There was no beaten road or path near the line of palisades, but, following the curving of the shore, a forest track, already green with the young grass that was pushing its way through last year's stubble, stretched away to the north and south. It was hardly more than a runway for the deer and wild cattle, but it did not give one the impression of having been originally plotted out by these creatures, after the immemorial fashion of their kind. An animal does not lay out his road in sections of perfectly straight lines connected by mathematical curves, neither does he fill up gullies nor cut through hills, when it is so easy to go around these obstructions.
