face of water, or imperfectly melted snow, which is now hard frozen again; and the thermometer having been frequently below zero, I suppose the ice may be four or five feet thick. Frequently there are great cracks across it, caused, I suppose, by the air beneath, and giving an idea of greater firmness than if there were no cracks; round holes, which have been hewn in the marble pavement by fishermen, and are now frozen over again, looking darker than the rest of the sur- face; spaces where the snow was more imperfectly dis- solved than elsewhere; little crackling spots, where a thin surface of ice, over the real mass, crumples be- neath one’s foot ; the track of a line of footsteps, most of them vaguely formed, but some quite perfectly, where a person passed across the lake while its sur- face was in a state of slush, but which are now as hard as adamant, and remind one of the traces discov- ered by geologists in rocks that hardened thousands of ages ago. It seems as if the person passed when the lake was in an intermediate state between ice and water. In one spot some pine boughs, which some- body had cut and heaped there for an unknown pur- pose. In the centre of the lake, we see the surround- ing hills in a new attitude, this being a basin in the midst of them. Where they are covered with wood, the aspect is gray or black ; then there are bare slopes of unbroken snow, the outlines and indentations being much more hardly and firmly defined than in summer. We went southward across the lake, (lirectly towards Monument Mountain, which reposes, as I said, like a headless sphinx. lts prominences, projections, and roughnesses are very evident; and it does not present a smooth and placid front, as when the grass is green and the trees in leaf. At one end, too, we are sensi-
