Feb In February the St. Lawrence ice began to move out of the Cabot Strait and on the 12th its eastern edge was reported about 50 miles NE of Scatari Island.

Apr During the early part of the month the St. Lawrence ice coming out of the Cabot Strait began to undergo rapid deterioration. The southwestern end of this ice moved to about the 61st meridian 30 miles S of Cape Canso but offered little hindrance to navigation.
