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.

YOUNG-ICE.—Nearly the same as "bay-ice," but generally applied to ice more recently formed than the latter.
