MINKEAL8 OCCUEEING IN CANADA. 85 



wick; aud at Alkow Harbor, Dean's Canal, in the province of British Columbia. 

 Localities and general mode of occurrence, T. S. Hunt, Geol. Can., 18G3, pp. 529, 793, 

 and Rep. Geol. Can., 18(13-00, pp. 218-223. Analyses, etc., of Canadian Graphite,

 graphite from Nova Scotia and New Brunswick, G. C. Hoffmann, Rep. Geol. Can ,

113. Grossul.vrite — Handsome specimens of a white lime-alumina garnet are found in 

 the township of Wakefield (Ottawa Co.), province of Qnel)(^c (G. F. Kunz, Anal., C. 

 Bullman, Am. Journ. Sci., 3 ser., vol. xxvii, p. 300, 1884). The white lime-alumina 

 garnet from Orford (Shcrljrooke Co., P. Que.), referred to under " Garnet," is also 

 referable to this variety. 



114. Gypsum— Occurs in connection with the Lower Carboniferous limestones, in enor- 

 mous deposits in the province of Nova Scotia. It is. largely quarried at "Windsor, 

 Newport, Walton, Wentworth, Shubenacadie, and a number of other places. It is 

 a very abundant mineral in the province of New Brunswick, the deposits being both 

 numerous and extensive. They occur in all parts of the Lower Carboniferous dis- 

 district, in King's, Albert, Westmorland, and Victori.a counties. Rock masses of 

 granular and compact gypsum, more or less mixed with dolomite, characterize the 

 Onondaga formation of western Ontario, and occur largely in the valley of the Grand 

 River, more especially in the townships of Dumfries, Brantford, Ont>ida, Seneca, and 

 Cayuga, etc. — It is also met with in the province of Manitoba. See also notes to 

 " Alabaster," " Selenite." 



115. Gyrolite — Is found on apophyllite in trap, about twenty-five miles south-west of 

 Cape Blomidon, between Margarclville and Port George, Annapolis county, province 

 of îsova Scotia. Anal., H. How, Ed. N. Phil. Journ., new series, vol. xiv, p. 117, 1861. 



110. Halite — An important deposit of rock salt is known to exist along the eastern shore 

 of Lake Huron, embracing the counties of Bruce, Huron and Lambton, in the province 

 of Ontario. It was first met with at Godcrich, in 1800, at a depth of 904 feet ; in the 

 year following at Clinton, at a depth of 1,180 feel, and in the succeeding year at 

 Kincardine, at a depth of about 900 feet ; subsequently at Seaforth at 1,035 feet, aud 

 again at Kingstone's Mills in Warwick, at 1,200 feet. A boring made in Goderich in 

 1876, and which was carried to a depth of 1,517 feet, has shown the existence of no 

 less than six beds of rock salt, one of which is close upon 31 feet, and another very 

 uearly 35 feet iu thickness. For geological details, records of borings, and analyses 

 of brines and salt, see following reports by Dr. T. Sterry Hunt—" On Brine-Springs 

 and Salt," Rep. Geol. Can., 1803-60, pp. 263-272. " On the Goderich Salt Region," 

 ib., 1866-69, pp. 211-242, and a second report on the Goderich salt region, ib., 1876-77, 

 pp. 221-243. 



117. Halotrichite — Has been found in some heaps of shale aud slack coal, at the Glace 

 Bay coal mines, in Cape Breton county, province of Nova Scotia. Anal., E. Gilpin, 

 Trans. N.S. Inst., vol. vi, p. 175, 1883-86. 



118. Heliotrope — Reported by Prof. How, as having been found by Dr. Gesner in small 

 nodules or fragments of rock on the beach of Chute's Cove (Annapolis Co.), has been 

 found, in situ, by Mr. C. W. Willimott, at Two Islands (Cumberland Co), province of 

 Nova Scotia.
