These enterprising Yankees have seized upon another profitable speculation here: there is a fish found in great quantities in the upper part of Lake Superior, called the skevát[38], so exceedingly rich, luscious, and oily, when fresh, as to be quite uneatable. A gentleman here told me that he had tried it, and though not very squeamish at any time, and then very hungry, he could not get beyond the first two or three mouthfuls; but it has been lately discovered that this fish makes a most luxurious pickle. It is very excellent, but so rich even in this state, that, like the tunny _marinée_, it is necessary either to taste abstemiously, or die heroically of indigestion. This fish is becoming a fashionable luxury, and in one of the stores here I saw three hundred barrels ready for embarkation. The Americans have several schooners on the lakes employed in these fisheries: we have not one. They have besides planned a ship canal through the portage here, which will open a communication for large vessels between Lake Huron and Lake Superior, as our Welland Canal has united Lake Erie with Lake Ontario. The ground has already been surveyed for this purpose. When this canal is completed, a vessel may load in the Thames, and discharge her burthen at the upper end of Lake Superior. I hope you have a map before you, that you may take in at a glance this wonderful extent of inland navigation. Ought a country possessing it, and all the means of life beside, to remain poor, oppressed, uncultivated, unknown? THE RAPIDS. But to return to my beautiful river and glorious rapids, which are to be treated, you see, as a man treats a passionate beauty--he does not oppose her, for that were madness--but he gets _round her_. Well, on the American side, further down the river, is the house of Tanner, the Indian interpreter, of whose story you may have heard--for, as I remember, it excited some attention in England. He is a European of unmixed blood, with the language, manners, habits of a Red-skin. He had been kidnapped somewhere on the American frontiers when a mere boy, and brought up among the Chippewas. He afterwards returned to civilised life, and having relearned his own language, drew up a very entertaining and valuable account of his adopted tribe. He is now in the American service here, having an Indian wife, and is still attached to his Indian mode of life.
