One afternoon, we visited a cave some two miles down the stream, which had recently been discovered. We squeezed and wriggled through a big crack or cleft in the side of the mountain for about one hundred feet, when we emerged into a large dome-shaped passage, the abode during certain seasons of the year of innumerable bats, and at all times of primeval darkness. There were various other crannies and pit-holes opening into it, some of which we explored. The voice of running water was everywhere heard, betraying the proximity of the little stream by whose ceaseless corroding the cave and its entrance had been worn. This streamlet flowed out of the mouth of the cave, and came from a lake on the top of the mountain; this accounted for its warmth to the hand, which surprised us all. Birds of any kind were rare in these woods. A pigeon hawk came prowling by our camp, and the faint piping call of the nuthatches, leading their young through the high trees, was often heard. On the third day our guide proposed to conduct us to a lake in the mountains where we could float for deer. Our journey commenced in a steep and rugged ascent, which brought us, after an hour's heavy climbing, to an elevated region of pine forest, years before ravished by lumbermen, and presenting all manner of obstacles to our awkward and incumbered pedestrianism. The woods were largely pine, though yellow birch, beech, and maple were common. The satisfaction of having a gun, should any game show itself, was the chief compensation to those of us who were thus burdened. A partridge would occasionally whir up before us, or a red squirrel snicker and hasten to his den; else the woods appeared quite tenantless. The most noted object was a mammoth pine, apparently the last of a great race, which presided over a cluster of yellow birches, on the side of the mountain. About noon, we came out upon a long, shallow sheet of water which the guide called Bloody-Moose Pond, from the tradition that a moose had been slaughtered there many years before. Looking out over the silent and lonely scene, his eye was the first to detect an object, apparently feeding upon lily-pads, which our willing fancies readily shaped into a deer. As we were eagerly waiting some movement to confirm this impression, it lifted up its head, and lo! a great blue heron. Seeing us approach, it spread its long wings and flew solemnly across to a dead tree on the other side of the lake, enhancing rather than relieving the loneliness and desolation that brooded over the scene. As we proceeded, it flew from tree to tree in advance of us, apparently loth to be disturbed in its ancient and solitary domain. In the margin of the pond we found the pitcher-plant growing, and here and there in the sand the closed gentian lifted up its blue head.
