Occasionally we wade through fields of snow, under whose depths the
river is lost for many rods, to appear again to the right or left,
where we least expected; still holding on its way underneath, with a
faint, stertorous,           sound, as if, like the bear and marmot,
it too had hibernated, and we had followed its faint summer trail to
where it earthed itself in snow and ice.
