Section II. Lines of Communication between the Mississippi Valley and that of the St. Lawrence.
There is no mountain chain between these two valleys; the basin of the great lakes, whose united waters form the St. Lawrence, is separated from the valley of the Mississippi only by a spur of the Alleghany system, not exceeding 450 feet in height, and sinking rapidly down toward the west, so as to be elevated but a few feet above the surface of Lake Michigan. During the rainy season, when the streams are swollen and the marshes of the water-shed are flooded, our Canadian countrymen were wont to pass in boats from Lake Michigan into the Illinois, by the Des Plains. The breadth of this dividing spur is more considerable than its height. It is not a ridge or crest, but rather a table-land, which imperceptibly merges by gentle slopes into the plains that surround it. Its level summit is filled with marshes, and therefore offers great facilities for feeding the canals which traverse it; further west, where it is scarcely higher than the rest of the country, it is often as dry as the surrounding prairies.
First Line. Ohio Canal.
Only one work connecting the two valleys is as yet completed, this is the Ohio canal, which traverses that State from North to South, extending from Portsmouth, on the Ohio, to the little city of Cleveland, which has sprung up on the shore of the lake since the canal was made. It is 334 miles in length, and cost nearly 4,500,000 dollars, or about 13,500 dollars per mile. This is low, yet the locks are all of hewn stone; the ground, however, was very favorable. The work was executed at the expense of the State, and was undertaken at the same time at Pennsylvania and Baltimore, on the traces of New York, started in the course of internal improvements. This young State, with a population of farmers, not having a single engineer within her limits, and none of whose citizens had ever seen any other canal than those of New York, has thus, with the aid of some second rate engineers borrowed from that State, constructed a canal longer than any in France, with more skill and intelligence than was displayed by Pennsylvania, in spite of the scientific lights of Philadelphia. This farming population of Ohio, almost wholly of New England origin, has a business instinct, a practical shrewdness, and a readiness to exercise all trades without having learned them, that would be sought in vain in the Anglo-German population of Pennsylvania. The legislators, under whose direction the public works were executed in both States, were, as is usual in the United States, a perfect copy of the mass of their constituents, with all its good and bad qualities. The Ohio canal commissioners added to a noble disinterestedness an admirable good sense, and to them is due the greater part of the glory of having planned and executed it. They were farmers and lawyers, who set themselves about making canals, naturally, easily, and without even a suspicion that in Europe no one dares to undertake such a work without long preparation and scientific studies. Now it is no longer an art in that State to plan and construct canals, but a mere trade; the science of canalling is there become quite an affair of the common people. The first-comer in a bar-room will explain to you, over his glass of whiskey, how to feed the summit level and how to construct a lock. All our mysteries in civil engineering are here fallen into the hands of the public, very much as the methods of descriptive geometry are to be found in the workshops, where they had been handed down by tradition, ages before Monge gave them the sanction of theory.
I have before said that Ohio, Indiana, and Illinois form a great triangle, wholly comprised within the Mississippi valley, with the exception of a narrow strip along the lakes, belonging, of course, to the St. Lawrence basin. The general slope of the surface is from north to south; the streams run mostly in that direction; this is especially true of the great tributaries of the Ohio. This arrangement of the secondary valleys is no less favourable to the construction of canals between the lakes, on the one side, and the Ohio and Mississippi on the other, than the configuration and humidity of the dividing table-land.
Second Line. Miami Canal.
Ohio has constructed another canal, which, starting from Cincinnati on the Ohio, runs north to Dayton, and is called the Miami canal. It is 65 miles in length, and cost nearly 1,000,000 dollars, or 15,400 dollars a mile. By the aid of a grant of land from Congress, and the State's resources, its prolongation is now in progress to Defiance, on the river Maumee, the site of a fortress of that name built by Gen. Wayne after his celebrated victory over the Indians. The Maumee, which was called by the French the Miami of the Lakes, is one of the principal tributaries of Lake Erie, and is to be canalled by the State. The distance from Dayton to Defiance is 125 miles; estimated cost 2,750,000 dollars, or 22,000 dollars per mile.
Third Line. Wabash and Erie Canal.
Ohio and Indiana, with the aid of a grant of land[BU] from Congress, have undertaken in concert a canal, which will connect the Wabash, one of the tributaries of the Ohio, with the Maumee. The greater part of the canal will be parallel to the two rivers, or in their beds; the length of the whole work will be 382 miles, of which 195 are in Indiana, and 87 in Ohio. The greater portion of the Indiana section lateral to the Wabash has been completed, but Ohio has not yet been able to commence her portion, because, owing to an absurd system of establishing boundaries, the mouth of the Maumee, whose whole course is in Ohio, will fall within Michigan.[BV] Ohio protests against this arrangement, Michigan stands firm to her claims; both sides have voted the sums needful for war, and both have taken arms; hostilities have even been begun, but the interference of the Federal government has led the parties to consent to an armistice. In this quarrel, Ohio has reason on her side, but Michigan appeals to the letter of the laws as favourable to her. It is probable that in creating Michigan a State, Congress will attach this strip to Ohio, to whom it is so important.[BW] In this unsettled state of things, Ohio has suspended the execution of her part of a work, which will give new importance to the mouth of the Maumee.
Fourth Line. Illinois and Michigan Canal.
The project of a canal from the Chicago, at the southern end of lake Michigan, to the head of steam navigation, that is, to the foot of the falls, in the River Illinois, has long been discussed. It is said to be of very easy construction; and that by means of a cut of the maximum depth of 26 feet, the summit level can be reduced to the level of Lake Michigan, so that the lake can be used as a feeder. It will be 96 miles in length, and will traverse a level or slightly undulating country, bare of trees, and still known by the name given it by the French Canadians, Prairie. It is proposed to construct this canal of larger dimensions than is common in the United States, so as to make it navigable by the lake-craft and steamboats. It is one of the most useful works ever undertaken in the world.[BX]
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.
The spirit of emulation which has prevailed among the States of the Union, has extended to the British Provinces, to the English population, which, leaving the lower part of the river to the French, has occupied Upper Canada. The inhabitants of this Province have embraced the opinion, that if the chain of communication which is broken by the cataracts and rapids, could be made whole, much of the produce, which now finds its way to the Mississippi, or to the Pennsylvania and New York canals, would seek a more convenient vent by the St. Lawrence, and that the British manufactures would take the same route up the river, through the ports of Quebec and Montreal, to the Western States. One canal has, therefore, already been executed around the falls of the Niagara, which forms a communication between Lakes Erie and Ontario; the Welland canal is 28 miles in length, exclusive of 20 miles of slack-water navigation. It is navigable by lake-craft of 120 tons, and has cost 2,000,000 dollars, nearly the whole of which was furnished by the upper Province, Lower Canada and the mother country having contributed a very trifling sum.
Since that work has been completed, the river below Lake Ontario has been surveyed, and it has been found that the aggregate length of the points not passable by steamboats of ten feet draft is only 30 miles, pretty equally divided between the two provinces. Upper Canada, which contains hardly 250,000 inhabitants, with no large towns and with little capital, has begun her portion of the work along the rapids within her limits. This work will be large enough to admit the passage of steamboats drawing nine feet water, and of the burden of 500 tons. I saw the labourers at work along the Long Saut Rapids at Cornwall, where there will be a cut of 13 miles in length; the estimated cost of this section is 1,250,000 dollars. The French population of Lower Canada, swallowed up in political quarrels, the result of which cannot be foreseen, neglects its essential interests in pursuit of the imaginary interests of national pride. It has done nothing towards continuing, within its limits, the great work, which has been begun by the poorer province of Upper Canada.
