Where the parts do not fit closely there is, of course, open water, which freezes over, in a few hours after giving off volumes of "frost-smoke." In obedience to renewed pressure this young ice "rafts," so forming double thicknesses of a toffee-like consistency.

Again the opposing edges of heavy floes rear up in slow and almost silent conflict, till high "hedgerows" are formed round each part of the puzzle.

At the junction of several floes chaotic areas of piled-up blocks and masses of ice are formed.

Sometimes 5-ft.

to 6-ft.
