great deposits of rich crystalline ores lying unused in the immediate 

 vicinity of the Coal-fields. The latest discovery of this kind is on the 

 French River, Pictou County, where beds of nodular clay ironstone 

 from G inches to 4 feet thick are reported, the ore containing 35 per 

 cent, of iron. 



In New Brunswick the beds of red hematite occurring at Jackson- 

 town, near Woodstock, in beds believed to be of Upper Silurian age, 

 are not now worked, though formerly successfully mined and smelted. 

 These beds are numerous, and from 6 inches to 8 feet thick. Their 

 geological characters seem to resemble those of the great Pictou 

 hematite already referred to. Bog iron ores, believed to be of com- 

 mercial value, are found at Burton, Sunbury County, and at Maryland, 

 York County. 



Iron ochres, used as "mineral paints," abound in connexion with 

 the deposits of iron ore as stated in Acadian Geology, and have been 

 worked on a limited scale at various points, as has also the umber of 

 Chester. 



Copper. — Though many indications of copper have been observed, 

 it is oidy recently that veins of workable dimensions have been 

 found in Xova Scotia. A locality at Poison's Lake (Ac. Geol., p. 

 692), which has attracted some attention for many years, has at 

 length revealed an apparently continuous vein of spathic iron holding 

 rich copper pyrites. A neighbouring area near the Lochaber Lake 

 exhibits several apparently rich veins, said to be 2 to G feet in 

 width. There can be little doubt that the former place will soon 

 become the seat of an important mining industry. The ores occur in 

 a slate formation associated with quartzitc, and which I believe to be 

 equivalent to the Cobcquid series. 



Attempts have recently been made to work the native copper in 

 the Triassic trap of Cape D'Or, and the nodules of gray copper in 

 the Carboniferous sandstones of New Annan, but with little success. 



In New Brunswick, ores of copper in veins, and disseminated 

 through slaty rocks, have been found in several places of the south 

 coast, in rocks of very similar character with those holding the 

 Nova Scotian ores above mentioned. The attempts to open them 

 profitably have hitherto been unsuccessful. Vitreous cojjper ore is 

 also found in connexion with the Triassic trap of Grand Manau, but 

 I have no definite information as to its economic importance. 



Manganese. — The peroxide of manganese, or Pyrolusite, occurring 

 in veins and "pockets" in the Ij^wcr Carboniferous limestone is 

 worked profitably at Maikh.uiiville, New Brunswick, and at Teny 

 Cape in Nova Scotia, where it occurs under similar conditions. This
