Having failed to enter Ashe’s Inlet on the inward voyage, we crossed the straits to Stupart’s Bay, in Prince of Wales’ Sound. Our visit to this station was too brief to allow me to make any fresh geological explorations in the neighborhood. The geology and scenery of this locality are described in my report of last year. The accompanying engraving, from a photograph, represents a view of the country from Eskimo Inlet, about two miles south of Stupart’s Bay, looking westward, and it may be taken as a characteristic specimen of the scenery on the south side of Hudson’s Straits. I found that Mr. Stupart and his associates had collected numerous geological specimens for me. They consisted of gneiss, soapstone, quartz, felspar, hornblende, mica-rock, epidote and iron pyrites, all apparently derived from ordinary Laurentian rocks, which prevail everywhere in this region. While at Port de Boucherville, on the south end of Nottingham Island, some further exploration was made in the vicinity, but nothing worthy of remark, was observed. [Sidenote: Niagara formation.] Last year Mansfield Island was found to consist of flat-lying, grey limestones. The fossils then collected, on its eastern side, although badly preserved and not numerous, indicate the age of our Niagara formation. [Sidenote: Southampton Island.] [Sidenote: Gneiss.] Similar limestones prevail on Southampton Island (proper) from Cape Southampton to within twenty-five or thirty miles of Cape Pembroke at its north-eastern extremity, the latter interval being occupied, according to Captain William Hawes, of the Hudson’s Bay Company, by rugged, dark-looking rocks, like those of Hudson’s Strait, which are Laurentian gneiss. The large island north of Southampton Island, of which Seahorse Point forms the eastern extremity, and which Lieutenant Gordon has called Bell’s Island, in the absence of any other name, is mountainous and appears to consist of gneiss.
