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.
SECT. III. LINES OF COMMUNICATION ALONG THE ATLANTIC.
FIRST LINE. INLAND CHANNELS BY THE SOUNDS AND BAYS ALONG THE ATLANTIC.
Upon examining the coast of the United States from Boston to Florida, it will be seen that there is almost a continuous line of inland navigation, extending from northeast to southwest in a direction parallel to that of the coast, formed, in the north by a series of bays and rivers, and in the south, by a number of long sounds, or by the narrow passes between the mainland and the chain of low islands that lie in front of the former. The necks of land that separate these bays, rivers, and lagoons, are all flat and of inconsiderable breadth. From Providence (42 miles south of Boston) to New York are Narragansett Bay and Long Island Sound, together 180 miles in length. Thence to reach to the Delaware you go to New Brunswick at the head of the Raritan Bay, where you encounter the New Jersey isthmus, a level tract, not more than 40 feet above the level of the sea, or than 35 to 40 miles in width. This neck is now cut across by the Raritan and Delaware Canal, a fine work, navigable by the small coasting craft, and 43 miles in length, exclusive of a navigable feeder 24 miles, all lately executed by a company, in less than three years, at a cost of about 2,500,000 dollars.[CB]
