The continent of America, if the stony records of the Past are read aright, claims to be the oldest instead of the newest portion of the globe. [According to some geologists, Labrador was the first part of our globe's surface to become dry land.] Bowing to this opinion of geologists till they see cause to express a different one, we will, in consequence, commence our survey of the world and its inhabitants with the Western Hemisphere. From the multitude of objects which crowd upon us, we can examine only a few of the most interesting minutely; at others we can merely give a cursory glance; while many we must pass by altogether,--our object being to obtain a general and retainable knowledge of the physical features of the Earth, the vegetation which clothes its surface, the races of men who inhabit it, and the tribes of the brute creation found in its forests and waters, on its plains and mountains. As we go along, we will stop now and then to pick up scraps of information about its geology, and the architectural antiquities found on it; as the first will assist in giving us an insight into the former conditions of extinct animals, and the latter may teach us something of the past history of the human tribes now wandering as savages in regions once inhabited by civilised men. Still, the study of Natural History and the geographical range of animals is the primary object we have in view. Though the best-known portions of the Polar Regions are more nearly connected with North America than with Europe or Asia, we propose to leave them to be fully described in another work. It is impossible, in the present volume, to embrace more than the continental parts of the Western World. Looking down on the continent of North America, which we will first visit, we observe its triangular shape: the apex, the southern end of Mexico; the base, the Arctic shore; the sides, especially the eastern, deeply indented, first by Hudson Bay, which pierces through more than a third of the continent, then by the Gulf of Saint Lawrence, and further south by Chesapeake Bay and the Bay of Fundy. On the western coast, the Gulf of California runs 800 miles up its side, with the Rio Colorado falling into it; and further north are the Straits of Juan da Fuca, between Vancouver's Island and the mainland, north of which are numerous archipelagoes and inlets extending round the great peninsula of Yukon to Kotzebue Sound. Parallel with either coast we shall see two great mountain-systems--that called the Appalachian, including the chain of the Alleghanies, on the east, and the famed Rocky Mountains on the west--running from north to south through the continent.
