MINERALS OCCURRING IN CANADA. 103 



258. Travertine — Deposits from cakareous spriugs — the material ol' which is in some 

 instances hard and solid, at other times porous and tufaceous — are abnudant in many 

 parts of western Ontario, being met with in the counties of York, "Wentworth, Oxford, 

 Wellington, G-rey, Simcoe, etc. 



259. Tremolite — Is abundant in the Laurcntiau limestones at the Calumet Fall.s in 

 Litchfield (Pontiac Co.), province of Quebec ; also in the townships of Blythfield 

 (Renfrew Co.), and Dalhousie (Lanark Co.), and short thick and highly modified 

 prisms of a white transparent tremolite, have been observed by Prof. Chapman, in a 

 white crystalline limestone in the township of Algona (Renfrew Co.), province of 

 Ontario. 



260. TURGITE — Occurs with brown hematite at Teny Cape, Hants county, province of 

 Nova Scotia. Anal., H. How, Phil. Mag., 4 ser., vol. xxxvii, p. 268, 1860. 



26L Ulexite — Occurs with cryptomorphite, Howlite, mirabilite, halite, Arragouite and 

 selenite in the gypsum deposits of Hants county — as at Clifton quarry, "Windsor; 

 Brookville ; Trecothick's quarry ; Three Mile Plains ; Wiukworth ; Newport Station 

 — province of Nova Scotia. Anal., H. How, Phil. Mag., 4 ser., vol. xxxv, p. 32, 1868. 



262. Uraconite — Was observed by Dr. Hunt, in the form of a sulphur-yellow crystalline 

 crust, lining fissures in magnetite in the township of Madoc (Hastings Co.), and by 

 Prof. Chapman, in a deposit of magnetite in the township of Snowden (Peterborough 

 Co.), province of Ontario. 



263. Uralite — Good specimens showing the partial and complete alteration of pyroxene 

 to uralite, have been found in the township of Templeton, Ottawa county, province 

 of Quebec. Analyses, B. J. Harrington, Rep. G-eol. Can., 181*J-1S, p. 20 G et seq. 



264. Uraninite — Has been found at the Villeneuve mica mine, in the township of 

 Villeneuve, Ottawa county, province of Quebec. Ann. Rep. Greol. Can., vol. ii, p. 10 t., 

 1886. 



265. Valentinite — Is found with native antimony, stibnite, senarmontite and kermesite, 

 in veins in argillite, in the township of South Ham, Wolfe county, province of 

 Quebec. 



266. Vesuvianite — Occurs in yellow crystals, with garnet, pyroxene and zircon, in 

 calcite, in the township of Greuville, and iji large brown crystals, with tourmaline, 

 at the Calumet Falls in Litchfield (Pontiac Co.) : in large brownish-red crystals in a 

 quartzose rock, in the township of Templeton (Ottawa Co.), and Dr. Harrington has 

 recorded the finding of small prisms of green idocrase imbedded in cinnamon stone, 



:.• in the township of Wakefield, in the same county — province of Quebec. 



26*7. ViviANlTE — An earthy form of this mineral, of a bright blue color, occurs underlying 

 a bed of bog iron-ore in Côte St. Charles, Vaudreuil (Vaudreuil Co ), in the province of 

 Quebec. It has also been met with, in a similar form, at the " Ramparts," Porcupine 

 River, Yukon district. North-west Territory. 



268. Wad — This variety of bog-manganese has been met with in Bolton (Brome Co.), 

 Staustead (Staustead Co.), Tring, Aubert-G-allion and Ste. Marie (Beauce Co.), and 

 several other localities in the province of Quebec. At Parrsborough (Cumberland
