vary from 73 6; the average being about 60 per cent. So much for 

 New Brunswick ores. 



In Nova Scotia the production of manganese is not so great, 

 althou;^h the mode of occurrence and treatment of the ore is similar to 

 that in New Brunswick. Pyrolusite — the high grade ore of manganese 

 — is more widely distributed. "On the south shore of Minas Basin 

 and midway between Noel and Walton, is situated the best-known and 

 most important manganese mine in Nova Scotia, the Teny Cape mines, 

 which, since its discovery in 186?, has been operated more or less con- 

 tinuously." Pyrolusite and manganite occur here, and assays are given 

 of specimens from " Teny Cape," " Cheverie " and " Douglas" locations, 

 made by Dr. Howe, E. Gilpin, Jr., and H. Poole respectively. These 

 indicate 85.54, 90.15 and 84.62 per rent, of manganese oxides present 

 in ihe ore. 



Oil Cape Breton Island, the Hon. E. P. Moseley, of Sydney, C.B., 

 has discovered and developed deposits of pyrolusite which promise well. 

 they are situated near Loch Lomond, and Mr. Brumell adds the report 

 made by Mr. Hugh Fletcher, of the Geological Survey staff, in his 

 report, addressed to the Director, for 1882-83 84. Upwards of 91 per 

 cent, of manganese dioxide occurred in this ore according to an analysis 

 by Mr. Frank Adams. 



Ontario and Quebec, etc., afford but small deposits of manganese 

 ores. In Stanstead and Bolton Townships, in Quebec, and in the 

 Magdalen Islands (teste J. Richardson in his report for 1879-80), as 

 well as near Batchewaherung Bay, Lake Superior, in Ontario, together 

 with a band of manganiferous spathic iron ore in the Nastapoka 

 Istands off the east side of Hudson's Bay, appear to be the only places 

 where ores of manganese are yet known outside of the Maritime 

 Provinces. 



Fossil Remains. — It might be added here that a number of fossil 

 remains have been found in Nova Scotia and New Brunswick entirely 

 filled and the hard parts replaced by pyrolusite. Amongst these is an 

 interesting ann well-preserved specimen of a pteropode (Conulara allied 

 to B. planpcostata, Dawsan) from the Lower Carboniferous of Spring- 

 field, where it was collected by Mr. A. E. Barlow in 1884.
