Anticosti, an uncultivated island in the gulf of St. Lawrence, 120 m. long and 30 m. wide in the centre, narrowing toward both ends. It divides the gulf into a N. and a S. channel. The E. point is in lat. 49° 5' N., lon. 62° W.; the W. point in lat. 49° 48', Ion. 04° 35'. Along a great part of the coast there is a dangerous belt of reefs uncovered at low tide. There are two harbors comparatively safe at all times: one at Gramache or Ellice bay, near the W. end, and the other at Fox bay on the northwest. The coast line on the S. side rises from 20 to 30 feet above the water; on the N. a succession of ridge-like elevations, separated by depressions, rise from 200 to 500 feet. On the S. side there are excellent peat beds 80 m. in length and 2 in width, with a depth of from 3 to 10 feet, and marl beds of considerable thickness. There are three lighthouses on the island.
