PANCAKE-ICE.--Newly formed ice, assuming the peculiar conformation
of numberless patches of "sludge," and giving the surface of the
sea the appearance of a handsome pavement.

PATCH of Ice.--The same as a pack, but of small dimensions.

SAILING-ICE.--Ice of which the masses are so much separated as to
allow a ship to sail among them.

SALLYING a Ship.--The operation of causing her to roll, by the men
running in a body from side to side, so as to relieve her from the
adhesion and friction of the young ice around her.

SLUDGE.--Ice of the consistence of thick honey, offering little
impediment to a ship while in this state, but greatly favouring
the formation of a "bay-floe."

STREAM.--A long and narrow, but generally continuous, collection
of loose ice.

TONGUE.--A mass of ice projecting under water from an iceberg or
floe, and generally distinguishable at a considerable depth of
smooth water. It differs from a "calf" in being fixed to, or a
part of the larger body.

WATER-SKY.--A dark appearance in the sky, indicating "clear water"
in that direction, and forming a striking contrast with the
"blink" over land or ice.
