Fifth Line. Western Pennsylvania Canal.
The canal which has been commenced by Pennsylvania between the Ohio and the town of Erie, 112 miles in length, and for feeding which extensive works have already been constructed around Lake Conneaut, will make another and a short line of water communication between the basins of the Mississippi and the St. Lawrence.
Different Lines.
Lastly, two canals are about to be undertaken, which will connect the Pennsylvania works with those of Ohio, and of consequence, form new connections between the Mississippi and the St. Lawrence. One of these is the Sandy and Beaver canal, which, beginning at the confluence of the Big Beaver with the Ohio, follows the latter to the mouth of the Little Beaver, ascends the valley of this stream, and passes down that of the Sandy River to the Ohio canal at Bolivar; the length will be 90 miles. From Bolivar to New York by the Ohio canal, Lake Erie, Erie canal, and the Hudson, the distance is 785 miles; by the new canal the distance from Bolivar to Philadelphia, that is, to the ocean, is only 512. The Mahoning canal leaves the Ohio canal at Akron, following the valleys of the Little Cuyahoga, the Mahoning, a tributary of the Big Beaver, and the Big Beaver, to the Ohio; it is about 90 miles in length; the distance from Akron to the river Ohio is 115 miles.
The generally level character of the surface of Ohio, Indiana, and Illinois is not less favourable to the construction of railroads than to that of canals. But as capital is scarce in this new country, which is as yet but imperfectly brought under cultivation, but few enterprises of much importance have hitherto been undertaken. The financial companies and institutions, which have always preceded the introduction of canals and railroads, have, however, been already established and are prosperous, and their success is the omen of the approach of the latter. In the absence of companies, the States are ready to adopt the most extensive schemes of public works; for the American of the West is not a whit behind the American of the East in enterprise. At present, I know of but a single railroad actually in process of construction beyond the Ohio, and that does not seem to be pushed forward with much activity; it is the Mad River railroad, which is to extend from Dayton, on the Miami canal, to Sandusky, on the bay of that name in Lake Erie; the length will be 153 miles. Many others have been projected in this region, and Indiana has caused surveys to be made for a railroad extending across the State from north to south, or from New Albany on the Ohio to some point on Lake Michigan.[BY]
Works for Improving the Navigation of the Ohio, Mississippi, and St. Lawrence.
To this head belong the works executed in the beds of the rivers themselves. The Mississippi is the beau idéal of rivers in regard to navigable facilities. From St. Louis to New Orleans, a distance of nearly 1200 miles, there is water enough for steamers of 300 tons throughout the year. Its yellow and muddy waters flow in a deep, although very circuitous channel, and its general breadth is from 800 to 1,000 yards, in places where it is not expanded to a much greater width by low, flat islands, thickly covered with trees. There are no sand-banks in this part of the channel, yet there are formidable dangers in the way of the inexperienced navigator; these are the trunks of trees, that have been carried away from the banks, as has been before mentioned, and in the removal of which the Federal government keeps steam snag-boats, the Heliopolis and Archimedes, employed; these boats are provided with a peculiar machinery by means of which they drag the trees up from the bed, and saw them into pieces of an inconsiderable length.
Captain Shreves, who has the command of these boats, and who invented the machinery, is also employed in constructing sunk dams of loose stones in the Ohio, which have the effect of increasing the depth of water in the dry season. He is at present engaged with a flotilla of steamboats in opening the bed of Red River, one of the great tributaries of the Mississippi, which the drift timber has choked up and covered over through a distance of 165 miles.[BZ] At Louisville, the Ohio, whose bed has generally a very slight inclination, has a descent of 22 feet in the distance of two miles, so as to be impassable for steamboats, except during the season of high water. The Louisville and Portland canal has been constructed by a company to avoid this obstruction; it is nearly one mile and three fourths in length, and cost 750,000 dollars.[CA] It receives the largest boats at a rate of toll which for the Henry Clay amounts to 175 dollars, and for the Uncle Sam 190 dollars. It has been proposed that Congress should buy this canal, and make the passage toll-free; and the importance of the navigation of the Ohio would justify the measure.
The St. Lawrence differs essentially from the Mississippi; instead of an expanse of muddy waters, it presents to the eye a clear blue surface. The Mississippi traverses a low, uninhabited, and uninhabitable region, of which the soil consists entirely of sand; or rather of mud deposited by the river-floods; not a stone as large as the fist is to be found, and only a few bluff points are met with which are above the reach of high water, and on which the pale inhabitants struggle unsuccessfully with the pestilential emanations of the surrounding swamps. The St. Lawrence flows through a broken, hilly, and sometimes rugged country, with a fertile soil, everywhere healthful, sprinkled with flourishing villages, which attract the eye of the traveller from a distance by their houses newly white-washed every year, and their churches built in the French style with their spires covered with tin. The Mississippi, like the Nile, has its annual overflow, or rather it has two in each year, but the spring-floods are much the most considerable. The St. Lawrence, owing to the vast extent of the lakes which serve as a reservoir and feeder to it, always preserves the same level, the extreme range of its rise and fall being only about 20 inches. The St. Lawrence, from the beauty of its waters, from their prodigious volume, from the country which it waters, and from the groups of isles scattered over it, would be one of the first rivers in the world in the eyes of the artist, but in those of the merchant, it is of quite a secondary importance. Its transparent waters hardly hide the numerous rocks; the navigation is interrupted first by the Falls of Niagara, and after it leaves Lake Ontario by numerous rapids, cataracts, or rocks between that lake and Montreal, and none but an Indian or a French Canadian, would dare to descend these points in that portion of the river in a canoe; at several points, the most powerful steamer would be unable to make head against the current.
