The natural features of Lower or Eastern Canada are unsurpassed by those of any other country in grace and variety: rivers, lakes, mountains, forests, prairies, and cataracts are grouped together in endless combinations of beauty and magnificence. The eastern districts, beginning with the bold sea-coast and broad waters of the St. Lawrence, are high, mountainous, and clothed with dark forests on both sides, down to the very margin of the river. To the north, a lofty and rugged range of heights runs parallel with the shore as far westward as Quebec; thence it bends west and southwest to the banks of the Ottawa. To the south, the elevated ridge, where it reaches within sixty miles of Quebec, turns from the parallel of the St. Lawrence southwest and south into the United States; this ridge, known by the name of the Alleganies, rises abruptly out of the Gulf of St. Lawrence at Perce, between the Baye de Chaleur and Gaspe Cape, and is more distant from the Great River than that upon the northern shore. Where the Alleganies enter the United States they divide the plains of the Atlantic coast from the basin of the Ohio; their greatest height is about 4000 feet above the level of the sea. The Valley of the St. Lawrence, lying between these two ranges of heights, is marked by great diversities of hill, plain, and valley. Both from the north and south numerous rivers pour their tributary flood into the great waters of Canada; of those eastward of the Saguenay little is known beyond their entrance; they flow through cliffs of light-colored sand, rocky, wooded knolls, or, in some places, deep, swampy moss-beds nearly three feet in depth. From the Saguenay to Quebec the mountain ridge along the shore of the St. Lawrence is unbroken, save where streams find their way to the Great River, but beyond this coast-border the country is in some places level, in others undulating, with hills of moderate height, and well-watered valleys. From Quebec westward to the St. Maurice, which joins the St. Lawrence at Three Rivers, the land rises in a gentle ascent from the banks of the Great River, and presents a rich tract of fertile plains and slopes: in the distance, a lofty chain of mountains protects this favored district from the bitter northern blast. Along the north bank of the St. Lawrence, from the St. Maurice, the country toward the Ottawa is slightly elevated into table ridges, with occasional abrupt declivities and some extensive plains. In this portion of Canada are included the islands of Montreal, Jesus, and Perrot, formed by the various branches of the Great River and the Ottawa, where their waters unite. Montreal is the largest and most fertile of these islands; its length is thirty-two miles and breadth ten; the general shape is triangular. Isle Jesus is twenty-one miles by six in extent, and also very rich; there are, besides, several other smaller islands of considerable fertility. Isle Perrot is poor and sandy.
