St., the largest river in North America, proceeding from Lake Ontario, from which it runs a course of 700 miles to the Atlantic ocean.

From Lake Ontario to Montreal this river has the name of Iroquois, and after taking a north-east course it embraces the island of Montreal, above which it receives Ottawa from the west, forming several islands of great fertility. From Montreal it takes the name of St Lawrence, and passing by Quebec, it meets the tide Lawrence more than 400 miles from the sea, and is so far navigable for large vessels. Having received in its course St John's, Seguin, Lefrancres, Trois Rivieres, and numberless other smaller streams, it falls into the ocean at Cape Rocheuses, by a mouth about 90 miles broad.

The principal entrance into the gulf of St Lawrence from the Atlantic ocean, is between capes Ray and Breton. It contains a number of islands, viz. St John's, at its southern extremity, on the coast of New Brunswick and Nova-Scotia; Anticosti, at the mouth of the St Lawrence, besides a number of small islands.

Prince Edward's island, about 120 miles in length, with a population of 8000 persons, is also in the gulf of St Lawrence. Here a new settlement was made by Lord Selkirk in 1823, composed of a colony of emigrants, amounting to 800, from the Highlands of Scotland.
