At length we turned up the Moosehorn, where the Indians at the carry had told us that they killed a moose the night before. This is a very meandering stream, only a rod or two in width, but comparatively deep, coming in on the right, fitly enough named Moosehorn, whether from its windings or its inhabitants. It was bordered here and there by narrow meadows between the stream and the endless forest, affording favorable places for the moose to feed, and to call them out on. We proceeded half a mile up this, as through a narrow winding canal, where the tall, dark spruce and firs and arbor-vitae towered on both sides in the moonlight, forming a perpendicular forest-edge of great height, like the spires of a Venice in the forest. In two places stood a small stack of hay on the bank, ready for the lumberer's use in the winter, looking strange enough there. We thought of the day when this might be a brook winding through smooth-shaven meadows on some gentleman's grounds; and seen by moonlight then, excepting the forest that now hems it in, how little changed it would appear! Again and again Joe called the moose, placing the canoe close by some favorable point of meadow for them to come out on, but listened in vain to hear one come rushing through the woods, and concluded that they had been hunted too much thereabouts. We saw many times what to our imaginations looked like a gigantic moose, with his horns peering from out the forest-edge; but we saw the forest only, and not its inhabitants, that night. So at last we turned about. There was now a little fog on the water, though it was a fine, clear night above. There were very few sounds to break the stillness of the forest. Several times we heard the hooting of a great horned-owl, as at home, and told Joe that he would call out the moose for him, for he made a sound considerably like the horn,--but Joe answered, that the moose had heard that sound a thousand times, and knew better; and oftener still we were startled by the plunge of a musquash. Once, when Joe had called again, and we were listening for moose, we heard come faintly echoing, or creeping from far, through the moss-clad aisles, a dull, dry, rushing sound, with a solid core to it, yet as if half smothered under the grasp of the luxuriant and fungus-like forest, like the shutting of a door in some distant entry of the damp and shaggy wilderness. If we had not been there, no mortal had heard it. When we asked Joe in a whisper what it was, he answered,-- "Tree fall." There is something singularly grand and impressive in the sound of a tree falling in a perfectly calm night like this, as if the agencies which overthrow it did not need to be excited, but worked with a subtle, deliberate, and conscious force, like a boa-constrictor, and more effectively then than even in a windy day. If there is any such difference, perhaps it is because trees with the dews of the night on them are heavier than by day.
