Birch, maple, poplar and all the natives of the American woods shouldered each other lustily. By the state of the fresh young leaves, just bursting their sheaths, Stern knew the season was mid-May.

Through the wind-swayed branches, little flickering patches of morning sunlight met his gaze, as they played and quivered on the forest moss or over the sere pine-spills.

Even upon the huge, squared stones which here and there lay in disorder, and which Stern knew must have fallen from the tower, the moss grew very thick; and more than one such block had been rent by frost and growing things.

“How long has it been, great Heavens! How long?” cried the engineer, a sudden fear creeping into his heart. For this, the reasserted dominance of nature, bore in on him with more appalling force than anything he had yet seen.

About him he looked, trying to get his bearings in that strange milieu.

“Why,” said he, quite slowly, “it's--it's just as though some cosmic jester, all-powerful, had scooped up the fragments of a ruined city and tossed them pell-mell into the core of the Adirondacks! It's horrible--ghastly--incredible!”

Dazed and awed, he stood as in a dream, a strange figure with his mane of hair, his flaming, trailing beard, his rags (for he had left the bear-skin in the arcade), his muscular arm, knotted as he held the sledge over his shoulder.

Well might he have been a savage of old times; one of the early barbarians of Britain, perhaps, peering in wonder at the ruins of some deserted Roman camp.

The chatter of a squirrel high up somewhere in the branches of an oak, recalled him to his wits. Down came spiralling a few bits of bark and acorn-shell, quite in the old familiar way.

Farther off among the woods, a robin's throaty morning notes drifted to him on the odorous breeze. A wren, surprisingly tame, chippered busily. It hopped about, not ten feet from him, entirely fearless.
