MINERALS FOR THE PARIS EXHIBITION. GILPIN. 253 



Ores less crystalline but equally pure occur at Loch Lomond 

 in Cape Breton County, at the Moseley Mines. The ore is found 

 in both the crystalline and amorphous forms in a red shale of 

 lower carboniferous age about five feet, thick. It is presented 

 as layers and beds from one to eighteen inches in thickness. 

 The enclosing material being soft it is readily extracted. The 

 position of the mine has necessitated unfavorable conditions for 

 shipment, but the construction of the railway now under con- 

 tract between the Strait of Canso and Louisburg will furnish a 

 ready access to admirable shipping facilities. 



The following analyses will serve to show its quality : 



I. II. ill. 



Peroxide of manganese (available). .. .91.84 87.64 92.C5 



Peroxide of iron , 12 trace. 4.14 



Insoluble 2.71 8.51 trace. 



The ores of this metal occnr in workable amounts in Onslow, 

 near Truro, as veins, and in the partings of the lower carboni- 

 ferous sandstones. 



During the past few months New Ross, in the northern part 

 of Lunenburg County, has promised to become a producer of 

 manganese ores. Miner T. Foster has opened a number of veins 

 which are of high grade, and available for economic extraction. 

 A few tons have been shipped, and have found a ready sale. 

 The extent of the manganiferous ground, and the age of the 

 strata holding the ores, has, I believe, not yet been worked out. 

 Explorations made during the past season, have shown that the 

 Dean and Chapter lands adjoining the Foster properties contain, 

 at several points, deposits which promise to be valuable. The 

 ores of this district have, so far as I can learn, not been exhaus- 

 tively analysed. They contain, however, manganese in amount 

 suitable for steel and chemical purposes. 



The Mineral Products Company of Bridgeville.Pictou County, 

 also exhibit samples of manganite, and of manganiferous 

 limonite. It is reported that recent developments in the iron 

 ore mines of this locality have shown the presence of consider- 

 able amounts of the latter mineral.
