equal distance. If he had described a fleet of such ships at anchor in a city’s port so far inland, we should have got a very different idea of the Orinoco. Perhaps Charlevoix describes the St. Lawrence truly as the most _navigable_ river in the world. Between Montreal and Quebec it averages about two miles wide. The tide is felt as far up as Three Rivers, four hundred and thirty-two miles, which is as far as from Boston to Washington. As far up as Cap aux Oyes, sixty or seventy miles below Quebec, Kalm found a great part of the plants near the shore to be marine, as glass-wort (_Salicornia_), seaside pease (_Pisum maritimum_), sea-milkwort (_Glaux_), beach-grass (_Psamma arenarium_), seaside plantain (_Plantago maritima_), the sea-rocket (_Bunias cakile_), &c. The geographer Guyot observes that the Maranon is three thousand miles long, and gathers its waters from a surface of a million and a half square miles; that the Mississippi is also three thousand miles long, but its basin covers only from eight to nine hundred thousand square miles; that the St. Lawrence is eighteen hundred miles long, and its basin covers more than a million square miles (Darby says five hundred thousand); and speaking of the lakes, he adds, “These vast fresh-water seas, together with the St. Lawrence, cover a surface of nearly one hundred thousand square miles, and it has been calculated that they contain about one half of all the fresh water on the surface of our planet.” But all these calculations are necessarily very rude and inaccurate. Its tributaries, the Ottawa, St. Maurice, and Saguenay, are great rivers themselves. The latter is said to be more than one thousand (?) feet deep at its mouth, while its cliffs rise perpendicularly an equal distance above its surface. Pilots say there are no soundings till one hundred and fifty miles up the St. Lawrence. The greatest sounding in the river, given on Bayfield’s chart of the gulf and river, is two hundred and twenty-eight fathoms. McTaggart, an engineer, observes that “the Ottawa is larger than all the rivers in Great Britain, were they running in one.” The traveller Grey writes: “A dozen Danubes, Rhines, Taguses, and Thameses would be nothing to twenty miles of fresh water in breadth (as where he happened to be), from ten to forty fathoms in depth.” And again: “There is not perhaps in the whole extent of this immense continent so fine an approach to it as by the river St. Lawrence. In the Southern States you have, in general, a level country for many miles inland; here you are introduced at once into a majestic scenery, where everything is on a grand scale,—mountains, woods, lakes, rivers, precipices, waterfalls.”
