Before we quit the subject of the western waters, we will take a view of their principal connections with the Atlantic. These are three; the Hudson river, the Potomac, and the Mississippi itself. Down the last will pass all heavy commodities. But the navigation through the Gulf of Mexico is so dangerous, and that up the Mississippi so difficult and tedious, that it is thought probable that European merchandise will not return through that channel. It is most likely that flour, timber, and other heavy articles will be floated on rafts, which will themselves be an article for sale as well as their loading, the navigators returning by land, or in light batteaux. There will, therefore, be a competition between the Hudson and Potomac rivers for the residue of the commerce of all the country westward of Lake Erie, on the waters of the lakes, of the Ohio, and upper parts of the Mississippi. To go to New York, that part of the trade which comes from the lakes or their waters, must first be brought into Lake Erie. Between Lake Superior and its waters and Huron, are the rapids of St. Mary, which will permit boats to pass, but not larger vessels. Lakes Huron and Michigan afford communication with Lake Erie by vessels of eight feet draught. That part of the trade which comes from the waters of the Mississippi must pass from them through some portage into the waters of the lakes. The portage from the Illinois river into a water of Michigan is of one mile only. From the Wabash, Miami, Muskingum, or Alleghany, are portages into the waters of Lake Erie, of from one to fifteen miles. When the commodities are brought into, and have passed through Lake Erie, there is between that and Ontario an interruption by the falls of Niagara, where the portage is of eight miles; and between Ontario and the Hudson river are portages at the falls of Onondago, a little above Oswego, of a quarter of a mile; from Wood creek to the Mohawks river two miles; at the little falls of the Mohawks river half a mile; and from Schenectady to Albany sixteen miles. Besides the increase of expense occasioned by frequent change of carriage, there is an increased risk of pillage produced by committing merchandise to a greater number of hands successively. The Potomac offers itself under the following circumstances: For the trade of the lakes and their waters westward of Lake Erie, when it shall have entered that lake, it must coast along its southern shore, on account of the number and excellence of its harbors; the northern, though shortest, having few harbors, and these unsafe. Having reached Cuyahoga, to proceed on to New York it will have eight hundred and twenty-five miles and five portages; whereas it is but four hundred and twenty-five miles to Alexandria, its emporium on the Potomac, if it turns into the Cuyahoga, and passes through that, Big Beaver, Ohio, Yohogany, (or Monongahela and Cheat,) and Potomac, and there are but two
