GEMS AND PRECIOUS STONES IN THE
thousand dollars' worth have been sold as specimens. Short's Claim, on the north shore of Lake Clear, yields the choicest twins. Perhaps the finest twin crystals ever found, and one of the best single crystals, are in the British Mu­seum Collection; while the best series of this mineral is probably that in the collection of Clarence S. Bement, of Philadelphia. An enormous single crystal is in the cabinet of the Academy of Natural Sciences at Philadelphia. In Burgess and adjoining townships fine crystals occur, not so large as those from Renfrew County, but of exquisite polish and highly modified forms; in Templeton and near Grenville, Que., especially four miles north, are found smaller crystals, often cherry-red and transparent, that would yield gems; and many of the crystals are modified and associated with wollastonite and graphite.
Tourmaline in green crystals is found in Chatham Town­ship, Que., and the green and red varieties in Villeneuve Town­ship, Que. Brown tourmalines are frequently met with in the Laurentian limestone. Fine crystals, rich yellowish or translu­cent brown in color, often occur imbedded in a flesh-red limestone in Ross, Ont., Calumet Falls, Clarendon, and Hunterstown, Que. These furnish an occasional gem. Slender crystals in white quartz occur at Fitzroy, Island Portage, and Lac des Chats, and of inferior color at McGregor's Quarry in Lachute, Ont. Black tourmaline of no gem value is found in a number of localities, principally at Yeo's Island, near the Upper end of Tar Island, one of the Thousand Islands. It occurs in large crystals at Murray Bay, Cape Tourmente, Que., and in white quartz near Bathurst, Ont.; in the granitic veins in Ross, Ont.; on Roche Fendue Channel, on Camping Place Bay, on Charles­ton Lake in Lansdowne, in Blythfield, on the Madawaska, and at North Elmsley and Lachute, Ont. ; and on the west side of the North River at St. Jerome, St. Felix, and Calumet Falls, Que. The velvet-black, fibrous tourmaline found at Madoc and Elzevir, Ont., gives a blue powder and is evidently an indicolite, like the variety from Paris, Me.
Almandite garnets occur plentifully in crystals in mica schist along the Stickeen River in British Columbia. Owing to their per­fect form and polish, the faces of these crystals are the most beau-
