Bay Of (So Called From The Great Heat Of The Weather When It Was First Visited By Jacques Cartier Chaleurs, the discoverer of Canada), a wide inlet of the gulf of St. Lawrence, which separates the province of Quebec from that of New Brunswick. It receives the waters of the Restigouche river, which have their source in the mountainous regions of Gaspe, of the Caraquet, the Bass, the Jaquette, the Benjamin, Tete a Gauche, Branche Sud, and Chariot. Here mackerel fishers are attracted in autumn, when that fish arrives in the course of its migrations. It has been a matter of dispute whether this is a bay in the sense of the term intended by the convention of 1818 between England and the United States, and whether the fishermen of the latter country, prior to the treaty of Washington, could be excluded from it. The doubt arose from its extent, 12 to 20 m. in width and 90 in length. Though there are some shallows at the entrance of one or two harbors, the bay affords safe navigation and secure anchorage. In 1700 a French fleet was defeated here by the British.
