continuance of the works on a large scale. The presence of coppei 

 ores at this place, associated with such a veinstone as sulphate 

 of harytes, affords some promise that if the excavations were 

 continued, valuable quantities of Buch ores would he discovered. 



White marhle occurs in the mctamorphic slates at Five Islands, 

 as well as a coloured marble of a purplish hue, with green spots 

 tinged by serpentine. These beds at Five Islands have not been 

 sufficiently opened fairly to test their quality. The white marble 

 affords small specimens of great purity and of very fine grain. Tin- 

 coloured variety has been objected to on the ground of unequal 

 hardness. 



Slate, apparently of good quality, is found in New Canaan, and 

 on the Middle Kiver of Pictou. It is not at present quarried, but 

 the first-mentioned locality would appear to present great facilities 

 for profitable working. 



Syenite and Porphyry, suitable for building and ornamental pur- 

 poses, occur in various parts of the Cobequid Mountains, and on 

 the east side of the Bras d'Or, and other places in Cape Breton. 

 Owing to their inland position, and the want of any internal demand, 

 these rocks are not at present quarried. 



Smoky Quartz, in large and beautiful crystals, is found in the 

 surface debris at Paradise in Annapolis County; and its native 

 matrix is a reddish compact felspar, which occurs in veins in the 

 granite of that district. 



Useful Minerals of the Upper Silurian in New Brunswick. 



The Upper Silurian rocks of Charlotte County afford promising 

 indications of lead and copper, and are a continuation of the metal- 

 liferous rocks of Washington County, Maine ; but little has yet been 

 done to ascertain their actual value. To this age are referred the 

 copper ores of Le Tete and the sulphate of harytes of Frye's Island, 

 said to be in large quantity and accessible. Copper and iron have 

 been stated to occur at Dickie Mountain and Bull Moose Hill, in 

 the Kingston group; but are not very favourably reported on by 

 Professor Bailey. As I have not personally examined any of the 

 localities, I may refer the reader for such information as if at present 

 to be obtained to the Reports of Professor Bailey and Professor Hind. 



It may be anticipated that the igneous and mctamorphic hills 

 of this district in Nova Scotia and New Brunswick, so varied in their 

 composition, and at present so little open to detailed investigation, 

 will be found to contain many useful minerals in addition \<> 1 1 1 -
