variety have lately been found by Dr. G. M. Dawson in British 

 Columbia. These are made up of several strata, and as these layers 

 are exceedingly thin, of different colours, conspicuous among which is 

 a bright green, they would cut into handsome Sardonyx gems. 



Chrysoptase occurs of various shades of green, and is translucent. 

 Its colour is due to the presence of a little nickel. This stone was 

 formerly greatly esteemed in Europe, but now is almost valueless. 

 This may be owing to the fact that its colour gradually fades in the 

 course of time. The mineral was found by Dr. Bell, of the Geological 

 Survey, in the Hudson Bay Territory. 



Prase h^s been noticed by Dr. Dawson, in British Columbia, of a 

 dark green colour. It would contribute a curious gem, but although it 

 takes a good polish, it is said to become spotted by long exposure to 

 the air. 



Jasper. — Another mineral of the many varieties of Quartz, may be 

 said to be quite common in Canada, and indeed only a few miles from 

 our doors, a band of variegated Jasper occurs, from bright red to various 

 shades of brown and yellow, with often the three colours intermingled. 

 Ribbon Jasper is of frequent occurrence in the Bay of Fundy, often of 

 a brownish base with yellow bands. At Two Islands, Minas Basin, in 

 Nova Scotia, a peculiar white porcelainous looking Jasper, interspersed 

 with rose coloined markings, occurs in veins of Basalt. It takes a high 

 polish and some specimens resemble hand-painted Porcelain. Jasper 

 of various colours may be found almost anywhere on the Bay of Fundy, 

 either in loose pebbles among the debris of the shore or in veins inter- 

 secting the Basalt. 



The occurrence of this mineral at Sherbrooke and Riviere Quelle 

 in the Eastern Townships in beds and veins is mentioned in the Geol- 

 ogy of Canada. This is, however, very uncertain in its polish at the 

 former locality, where this mineral is of various shades of red. Specular 

 Iron ore, together with numerous small holes, render it entirely useless 

 as an ornamental stone. The Riviere Quelle specimens, which are 

 often beautifully variegated, will occasionally take a good polish. The 

 so-called " Gaspe Pebbles " are generally Jasper. In the Lake Superior 

 district, in Qntario, Jasper of different colours is found, both in veins 

 and pebbles, the latter enclosed in a translucent quartzite, forms large
