[Footnote 137: "There are two lakes in Lower Canada, Matapediac and Memphremagog. The former is about 16 miles long, and three broad in its greatest breadth, about 21 miles distant from the St. Lawrence River, in the county of Rimouski; amid the islands that separate the waters running into the St. Lawrence from those that run to the Bay of Chaleurs, it is navigable for rafts of all kinds of timber, with which the banks of the noble River Matapediac are thickly covered. Memphremagog Lake, in the county of Stanstead, stretching its south extremity into the State of Vermont, is of a semi-circular shape, 30 miles long, and very narrow. It empties itself into the fine river St. Francis, by means of the River Magog, which runs through Lake Scaswaninepus. The Memphremagog Lake is said to be navigable for ships of 500 tons burden."--Martin's _History of Canada_, p. 102.] [Footnote 138: "It is worthy of remark, that the great lakes of Upper Canada are liable to the formation of the Prester or water-spout, and that several instances are recorded of the occurrence of that truly extraordinary phenomenon, the theory of which, however, is well known. Whether electricity be a cause or a consequence of this formidable meteor, appears, nevertheless, to be a question of some doubt among natural philosophers; Gassendi being disposed to favor the former opinion, while Cavallo espouses the latter."--Bouchette's _Topographical and Statistical Description of Upper and Lower Canada_, vol. i., p. 346.]
