50 (p. 205).--Another name for the St. Lawrence River. The apparent etymology of this name would suggest that it was given on account of the powerful current of the river, and its discharge into the Gulf of St. Lawrence. See Trumbull's "Composition of Indian Geographical Names," in _Conn. Histor. Soc. Colls._, vol. ii., p. 30. Laverdière erroneously considers _Sacqué_ as another form of Sagné, or Saguenay. 51 (p. 205).--One of the principal tributaries of the St. Lawrence, entering the latter 120 miles N. E. of Quebec. It is 100 miles in length, and remarkable for its wild and picturesque scenery; along the lower half of its course the banks vary in height from 500 to 1,500 feet, often overhanging the swift current below. Its ordinary depth varies from 100 to 1,000 feet, and even reaches over 3,000 feet near its month. It is the outlet of Lake St. John, and was for the French the chief avenue of approach to the Indian tribes around that lake, and even (by portages) to those of Hudson Bay region. This river was, throughout the French régime, the center of both trading and missionary activities for all Northeastern Canada. Tadoussac, at its month, from earliest times a favorite rendezvous of the Montagnais and other Eastern tribes, became under the French an important fur-trade center and Jesuit mission; and is, to-day, a notable watering-place. The name is also spelled Sagnay, Sagné, Saghuny, etc. Thévet, in his _Grande Insulaire_ (a MS. preserved in the Bibliothèque Nationale of Paris, and written before 1571: see Harrisse's _notes sur la Nouvelle France_, p. 278), declares that the savages then called this river _Thadoyseau_; while Lalemant (in _Relation_ of 1646) says that they called Tadoussac _Sadilege_. Probably these names were indifferently applied, in that early time, alike to river and village. Laverdière derives Saguenay from the Montagnais _saki-nip_, "the rushing water." See his _Champlain_, pp. 68, 69; also Trumbull, in _Conn. Hist. Colls._, vol. ii., p. 31. 52 (p. 205).--Now the St Maurice; named _Trois Rivières_, because two islands at its mouth divide it into three channels. On Creuxius' map (1660), it appears as Metaberoutin River, or Three Rivers; on Duval's (1679), the Rivière de Foix. This last appellation seems to be another form of Riuiere du Fouez, given to this river by Cartier. See _Champlain's Voyages_ (Prince Soc.), vol. i., p. 257. At its mouth is the town of Three Rivers, founded by Champlain in 1634. 53 (p. 205).--The Ottawa River--Champlain's Riuière des Algommequins; see his "Explanation of the Map of New France," in _Voyages_ (Prince Soc.), vol. i., p. 302. Also named, in early days, Rivière des Prairies; so in _Relation_ of 1640, _post_, and on Creuxius' map (1660): Faillon (_Col. Fr._, i., p. 82, _note_ * *) says it was thus named from its discoverer, a young sailor from St. Malo; he is mentioned by Champlain as "a very courageous man," in _Voyages_ (Paris, 1632), p. 159.
