50. The fall in the Rideau is thirty-four feet, according to the Edinburgh Gazetteer of the World. The estimate of Champlain is so far out of the way that it seems not unlikely that feet were intended instead of fathoms. Vide Vol. I. pp. 301, 302.
51. The Chaudière Falls, just above the present city of Ottawa, the greatest height of which is about forty feet "Arrayed in every imaginable variety of form, in vast dark masses, in graceful cascades, or in tumbling spray, they have been well described as a hundred rivers struggling for a passage. Not the least interesting feature they present is the Lost Chaudière, where a large body of water is quietly sucked down, and disappears underground" Vide Canada by W. H Smith. Vol. I. p. 120. Also Vol I. p, 120 of this work.
52. The latitude of the Chaudière Falls is about 45° 27'.
53. Chaudière Lake, which was only an expansion of the River Ottawa.
54. Rapide des Chats.
55. This probably refers to that part of the fall which was more difficult to pass.
56. Lake des Chats. The name des chats appears to have been given to this Lake, the Rapids, and the Nation des chats, on account of the great number of the loup cervier, or wild cats, chats sauvages, found in this region. Cf. Le Grande Voyage du Pays des Hurons, par Sagard, Paris, 1632, p. 307.
57. Madawaskca River, an affluent of the Ottawa, uniting with it at Fitz Roy.
58. Probably an allusion to the River St. Lawrence.
59. This is the same tribe alluded to by Vimont under the name Mataouchkarmi, as dwelling south of Allumette Island. Vide Relations des Jésuites, 1640, Quebec ed., p. 34.
