But Collinson was no longer alone. Hitherto his characteristic reveries had been of the past,--reminiscences in which there was only recollection, no imagination, and very little hope. Under the spell of Chivers's words his fancy seemed to expand; he began to think of his wife as she might be now,--perhaps ill, despairing, wandering hopelessly, even ragged and footsore, or--believing HIM dead--relapsing into the resigned patience that had been his own; but always a new Sadie, whom he had never seen or known before. A faint dread, the lightest of misgivings (perhaps coming from his very ignorance), for the first time touched his steadfast heart, and sent a chill through it. He shouldered his weapon, and walked briskly towards the edge of the thick-set woods. There were the fragrant essences of the laurel and spruce--baked in the long-day sunshine that had encompassed their recesses--still coming warm to his face; there were the strange shiftings of temperature throughout the openings, that alternately warmed and chilled him as he walked. It seemed so odd that he should now have to seek her instead of her coming to him; it would never be the same meeting to him, away from the house that he had built for her! He strolled back, and looked down upon it, nestling on the ledge. The white moonlight that lay upon it dulled the glitter of lights in its windows, but the sounds of laughter and singing came to even his unfastidious ears with a sense of vague discord. He walked back again, and began to pace before the thick-set wood. Suddenly he stopped and listened. To any other ears but those accustomed to mountain solitude it would have seemed nothing. But, familiar as he was with all the infinite disturbances of the woodland, and even the simulation of intrusion caused by a falling branch or lapsing pine-cone, he was arrested now by a recurring sound, unlike any other. It was an occasional muffled beat--interrupted at uncertain intervals, but always returning in regular rhythm, whenever it was audible. He knew it was made by a cantering horse; that the intervals were due to the patches of dead leaves in its course, and that the varying movement was the effect of its progress through obstacles and underbrush. It was therefore coming through some "blind" cutoff in the thick-set wood. The shifting of the sound also showed that the rider was unfamiliar with the locality, and sometimes wandered from the direct course; but the unfailing and accelerating persistency of the sound, in spite of these difficulties, indicated haste and determination.
