Great Rivers.
The rivers which rise on the eastern side of the Appalachian range run into the Atlantic; those which rise west of the Rocky Mountains empty themselves into the Pacific; while the mighty streams which flow between the two, pass through the great basin of the Mississippi, and swell the waters of that mother of rivers. The great valley of the Mississippi, indeed, drains a surface greater than that of any other river on the globe, with the exception perhaps of the Amazon. The Missouri, even before it reaches it, runs a course of 1300 miles, while the Mississippi itself, before its confluence with the Missouri, has already passed over a distance of 1200 miles; thence to its mouth its course is upwards of 1200 miles more. The Arkansas, which flows into it, is 2000 miles long, and the Red River of the south 1500 miles in length; while the Ohio, to its junction with the Mississippi, is nearly 1000 miles long.
North America may be said to contain four great valleys—that of the Mississippi, running north and south; that of the Saint Lawrence, from the south-west to the north-east; that of the Saskatchewan, extending from the Rocky Mountains below Mount Brown to Lake Superior; that of the Mackenzie, from the Great Slave Lake to the Arctic Ocean. Although a large portion of the eastern side of the continent is densely-wooded, there are towards the west, extending from the Gulf of Mexico to the Arctic Ocean, vast plains. In the south they are treeless and barren in the extreme; while advancing northward they are covered with rich grasses, which afford support to vast herds of buffaloes, as well as deer and other animals.
Lakes.
The most remarkable feature in North America is its lake system—the largest and most important in the world. In the north-west, at the foot of the Rocky Mountains, are the Great Bear and Great Slave Lakes, which discharge their waters through the Mackenzie River into the Arctic Ocean. Next we have the Athabasca, Wollaston, and Deer Lakes. In the very centre of the continent are the two important lakes of Winnipeg and Winnipegoos,—the former 240 miles in length by 55 in width, and the latter about half the size. The large river of the Saskatchewan flows into Lake Winnipeg, and with it will, ere long, form an important means of communication between the different parts of that vast district lately opened up for colonisation. At its southern end the Red River of the north flows into it, on the banks of which a British settlement has long been established. Several streams, however, make their way into Hudson Bay. Between it and Lake Superior is an elevated ridge of about 1500 feet in height; the streams on the west falling into Lake Winnipeg, while those which flow towards the east reach Lake Superior.
We now come to the site of the five largest fresh-water lakes in the world. Lake Superior extends, from west to east, 335 miles, with an extreme breadth of 175. Its waters flow through the Saint Mary’s River by a rapid descent into Lake Huron, which is 240 miles long. This lake is divided by the Manitoulin islands into two portions, and is connected with Lake Michigan by a narrow channel without rapids, so that the two lakes together may be considered to form one sheet of water. On its southern extremity the waters of Lake Huron flow through another narrow channel, which expands during part of its course into Lake Saint Clair; and they then enter Lake Erie, which has a length of 265 miles, and a breadth of 80 miles. It is of much less depth than the other lakes, and its surface is therefore easily broken up into dangerous billows by strong winds. Passing onward towards the north-east, the current enters the Niagara River, about half-way down which it leaps along a rocky ledge of 100 feet in height, to a lower level, forming the celebrated Falls of Niagara, and then passes on in a rapid course into Lake Ontario. The fall between the two lakes is 333 feet. Lake Ontario is 180 miles long and 65 miles wide. Out of its north-eastern end falls the broad stream which here generally takes the name of the Saint Lawrence, and which proceeds onward, now widening into lake-like expanses full of islands, now compressed into a narrow channel, in a north-easterly direction. The true Saint Lawrence may indeed be considered as traversing the whole system of the great lakes of
North America, and thus being little less than a thousand miles in direct length; indeed, including its windings, it is fully two thousand miles long. To the north-west of it exist countless numbers of small lakes united by a network of streams; while numerous large rivers, such as the Ottawa, the Saint Maurice, and the Saguenay, flow into it, and assist to swell its current. There are numerous other small lakes to the west of the Rocky Mountains, a large number of which exist in the Province of British Columbia, and are more or less connected with the Fraser and Columbia Rivers. Further to the south are other lakes, many of them of volcanic origin, some intensely salt, others formed of hot mud. Among these is the Great Salt Lake, in the State of Utah. To the south of the Saint Lawrence also is Lake Champlain, 105 miles long, though extremely narrow,—being only 10 miles in its widest part, narrowing in some places to half a mile. Near it is the beautiful Lake Saint George, with several other small lakes; and lastly, in Florida, there is a chain of small lakes, terminating in Lake Okechodee—a circular sheet of water about thirty miles in diameter.
We must now proceed more particularly to examine the regions of which we have obtained the preceding cursory view, but, before we do so, we must glance at their human inhabitants.
