ters 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 8 feet draught. That part of the trade which comes from the waters of the Missisipi 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 1 mile only. From the Wabash, Miami, Muskingum, or Alleghaney, are portages into the waters of Lake Erie, of from 1 to 15 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 8 miles; and between Ontario and the Hudson's 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 2 miles; at the little falls of the Mohawks River half a mile, and from Schenectady to Albany 16 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 Patowmac 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 Cayahoga, to proceed on to New York it will have 825 miles and five portages; whereas it is but 425 miles to Alexandria, its emporium on the Patowmac, if it turns into the Cayahoga, and passes through that, Bigbeaver, Ohio, Yohoganey, (or Monongalia and Cheat,) and Patowmac, and there are but two portages; the first of which between Cayahoga and Beaver may be removed by uniting the sources of these waters, which are lakes in the neighborhood of each other, and in a champaign country; the other from the waters of Ohio to Patowmac will be from 15 to 40 miles, according to the trouble which shall betaken to approach the two navigations.
