48. This passage is exceedingly obscure. Laverdiere supposes that part of a sentence was left out by the printer. If so it is remarkable that Champlain did not correct it in his edition of 1632. Laverdiere thinks the river here spoken of is the Gatineau, and that the savages following up this stream went by a portage to the St. Maurice, and passing down reached the St. Lawrence _thirty_ leagues, and not _three_, below the Falls of Saint Louis. The three rivers thus named inclose or form an island of about the extent described in the text. This explanation is plausible. The passage amended would read, "This river _extends near another which_ falls into the great river St. Lawrence thirty leagues below the falls of St. Louis." We know of no other way in which the passage can be rationally explained. 49. Rideau, at the mouth of which is Green Island, referred to in the text below. 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 Chaudiere 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 Chaudiere, 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 Chaudiere Falls is about 45 deg. 27'. 53. Chaudiere 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 Jesuites_, 1640, Quebec ed., p. 34. 60. Cypres, Red Cedar or Savin, _Juniperus Virginiana_. _Vide_ Vol. II. note 168.
