_Lake Champlain_ is about one hundred and twenty miles in length, and is of various breadths: for the first thirty miles it is, in no place, more than two miles wide; beyond this, for the distance of twelve miles, it is five or six miles across; but it afterwards narrows, and again, at the end of a few miles, expands. That part called the _Broad Lake_, because broader than any other, is eighteen miles across. Here the lake is interspersed with a great number of islands. The soundings of Lake Champlain are, in general, very deep; in many places they are sixty and seventy, and in some even one hundred fathoms in depth. The scenery, along the shores of the lake, is extremely grand and picturesque; particularly beyond Crown Point. Here they are beautifully ornamented with hanging woods and rocks; and the mountains, on the western side, rise in ranges one behind another, in the most magnificent manner possible. * * * * * Crossing from the head of Lake Champlain, westward to the river St. Lawrence, we shall describe the places adjacent to that river, and some of the north-western parts of the state of New York, in _A Narrative of_ LIEUTENANT HALL'S _Journey from Canada to the Cataract of Niagara._ Mr. Hall had travelled from Montreal, in Canada, to Prescott, in a stage-waggon, which carried the mail; and he says that he can answer for its being one of the roughest conveyances on either side of the Atlantic. The face of the country is invariably flat; and settlements have not, hitherto, spread far from the banks of the _St. Lawrence_. _Prescott_ is remarkable for nothing but a square redoubt, or fort, called Fort Wellington. The accommodations at this place were so bad that Mr. Hall, at midnight, seated himself in a light waggon, in which two gentlemen were proceeding to Brockville. These gentlemen afterwards offered him a passage to Kingston, in a boat belonging to the British navy, which was waiting for them at _Brockville_. The banks of the river St. Lawrence, from the neighbourhood of Brockville, are of limestone, and from twenty to fifty feet in height. Immense masses of reddish granite are also scattered along the bed of the stream, and sometimes project from the shore. The numerous islands which crowd the approach to _Lake Ontario_, have all a granite basis: they are clothed with cedar and pine-trees, and with an abundance of raspberry plants. The bed of the _Gananoqua_ is also of granite. This river is rising into importance, from the circumstance of a new settlement being formed, under the auspices of the British government, on the waters with which it communicates.
