distinguished from a ship's masthead. A "bay-floe" is a floe of
ice newly formed.

floes, not more than a furlong square.

A HOLE or POOL of Water.--A small space of "clear water," when the
rest of the sea is covered with ice.

HUMMOCK.--A mass of ice rising to a considerable height above the
general level of a floe, and forming a part of it. Hummocks are
originally raised by the pressure of floes against each other.

LAND-ICE.--Ice attached to the land, either in floes or in heavy
grounded masses lying near the shore.

LANE of Water.--A narrow channel among the masses of ice, through
which a boat or ship may pass.

LEAD.--A channel through the ice. A ship is said to "take the
right lead" when she follows a channel conducting her into a more
navigable sea, and _vice versâ_.
