ICEBERG. An insulated mountain of ice, whether on Arctic lands or floating in the sea. Some have been known to be aground in 120 fathoms water, and rise to the height of 150 feet above it. Cook's obtaining fresh water from floating icebergs was not a new discovery. The Hudson's Bay ships had long made use of it; and in July, 1585, Captain Davis met with ice "which melted into very good fresh water."
ICE-BIRDS. Small sea-fowl in the polar regions.
ICE-BLINK. A streak or stratum of lucid whiteness which appears over the ice in that part of the atmosphere adjoining the horizon, and proceeds from an extensive aggregation of ice reflecting the rays of light into the circumambient air.
ICE-BOAT. A peculiar track-schuyt for the Dutch canals in winter.
ICE-BOUND. A vessel so surrounded by ice as to be prevented from proceeding on her voyage.
ICE-CHISEL. A large socket-chisel into which a pole is inserted, used to cut holes in the ice.
ICE-CLAWS. A flat claw with two prongs spread like a can-hook; the same as a single span or claw-dog.
ICE-FENDERS. Fenders of any kind, used to protect a vessel from injury by ice; usually broken spars hanging vertically where the strain is expected.
ICE LANE or Vein. A narrow temporary channel of water in the packs or other large collections of ice.
ICE-MASTER. A pilot, or man of experience, for the Arctic Sea.
