" The spruce and cedar on its shores, hung with gray lichens, looked at a distance like the ghosts of trees. Ducks were sailing here and there on its surface, and a solitary loon, like a more living wave, — a vital spot on the lake's surface, — laughed and frolicked, and showed its straight leg, for our amusement. "
