Rh 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."

We have not yet the data for a minute comparison of the St. Lawrence with the South American rivers; but it is obvious that, taking it in connection with its lakes, its estuary, and its falls, it easily bears off the palm from all the rivers on the globe; for though, as Bouchette observes, it may not carry to the ocean a greater volume of water than the Amazon and Mississippi, its surface and cubic mass are far greater than theirs. But, unfortunately, this noble river is closed by ice from the
