A specimen of similar pyrites, obtained from a place on this coast which the Eskimo call Iñari, in 1879, had a small quantity of light bluish-grey magnesian limestone adhering to it. These specimens, which all resemble the pyrites from Tilt Cove in Newfoundland and Capelton in the Eastern Townships, except in the absence of copper, are evidently from good-sized veins. The mineral is in common use among the Eskimo for striking fire. The discovery of traces of gold and silver in the specimen last assayed by Mr. Hoffmann is interesting. Specks of gold are mentioned by Tennant in a specimen of quartz from Repulse Bay. [Sidenote: Huronian series on the N. W. side of Hudson’s Bay.] The majority of the lithological specimens brought from the coast in the whole interval between Eskimo Point and Repulse Bay, correspond with the rocks of the Huronian series. Laurentian types are absent from the collections. So far as we know, therefore, the probabilities are that Huronian rocks prevail all along the north-west coast of Hudson’s Bay, from Eskimo Point to Chesterfield Inlet, and again at Repulse Bay; possibly also, in the interval between the last mentioned localities. [Sidenote: Quartzite of Marble Island.] [Sidenote: Quartzite on mainland.] [Sidenote: Quartzite in the interior.] Marble Island, as far as examined, consists mainly of light-colored, fine grained quartzite, associated with glossy mica-schists. Among the specimens obtained from the mainland, is one of similar quartzite of a delicate pink or flesh-color, from a point on the south side of Nevil Bay. On Marble Island the average strike is south-westward or in this direction, so that the two localities may occupy the same geological horizon. White quartzite is reported as occurring further south-west in the interior, especially in the region to the north-east of Hatchet or Wollaston Lake, and in my report for 1882, page 28 C C, it was stated that boulders of this rock are abundant at the Long or Methy Portage, still further south-west.
