the Townships of Grcnvillo, Wakefield, Templeton and the Calumet 

 Islands, is usually in hair-brown crystals, except in the first named 

 Township the colour is a yellow, all of which are translucent only on 

 their edges, except in the case of some very small crystals from 

 Wakefield, which were semi-transparent. No gem material of this 

 mineral has yet been met with in Canada. 



Lazulite. — Ihis mineral was found by Dr. R. Bell on the Churchill 

 River ot a cobalt-blue colour. This material is sometimes employed as 

 a substitute for T.apis-lazuli, which it resembles ^on'.ewhat in colour. 



Sodalite is another blue mineral, which occurs associated with 

 granite on the Rocky Mountains in British Columbia. It varies in 

 colours from light to dark blue, from translucent to opaque. From a 

 large number of specimens examined 1 should think that fair-sized 

 blocks of the Granite, interspersed with veins and patches of Sodalite, 

 could be obtained which would make a very handsome ornamental 

 stone. As a gem material it compares with the Lapis-lozuli, is the 

 same hardness, and takes a higher polish. The largest stotie ot this 

 material, free from any adhering rock, that has been cut in Canada, 

 would be about one and half inches by three-quarters, and three-quarters 

 of an inch thick. 



Chlorastrolite was thought, until recently, to be confined to Isle 

 Royal, but has lately been found in a place I believe on the Canadian 

 side. In the neighbourhood of Lake Superior they are often called 

 Turtle Agates, owing to the markings of the stone, resembling the 

 grotesque designs often seen on some species of turtles. They occur 

 in rounded pebbles of various sizes, of dark green colours mottled and 

 veined with white ; they are perfectly opaque, and a stone of a good 

 colour and marking makes a very pretty gem. 



PreJmite, of which the former Chlorastrolite is supposed to be a 

 variety, occurs at several places in the Lake Superior district, also at 

 the Bale des Chaleurs in New Brunswick, and at the Bay of Furdy ir 

 Nova Scotia. In the first named area, independent of the important 

 veins of this mineral which sometimes form the gangue ot rich native 

 Copper deposits, pebbles of \arious colours, sometimes radiating, are 

 found among the debris of the shore, generally enclosing scales of the 

 ame mineral. The pale greenish variety of the Baie des Chaleu-s, and
