Bay Of Fundy, a deep inlet of the Atlantic, separating the Canadian provinces of Nova Scotia and New Brunswick. It is about 170 m. long, and from 30 to 50 m. wide. From its mouth, between the S.W. extremity of Nova Scotia and the easternmost point of Maine, its coasts trend N. E. until near its upper extremity it branches into two inlets; the northern, called Chignecto bay, is about 30 m. long and 8m. broad; the southern bears the name of Minas channel, and opens into Minas basin in Nova Scotia. At St. John, N. B., situated at the mouth of the river St. John, on the N. coast, the bay is 36 m. wide, and it continues of nearly uniform width from that point to its branching. It is deep, but difficult of navigation. It is remarkable for its extraordinary tides, which rush up from the sea with such rapidity as sometimes to overtake swine feeding on shellfish on the shores, and rise in Minas basin 40 ft., and in Chignecto channel 60 ft. Grand Manan, Campo Bello, and Long islands lie at the mouth of the bay, which receives the rivers St. John and St. Croix.
