and Walton, is situated the best known and most important man- 
ganese mine in Nova Scotia, the Teny Cape mine, which, since 
its discovery in ISGli, has been operated more or less continuously. 
The ores, consisting mainlv of pyrolusite and manganite, are 
found in the Carboniferous limestone which may be traced for 
many miles on the south shore of Minas Basin, the limestone im- 
mediately in connection with the ore deposits being highly man- 
ganiferous and interstratified with small beds and masses of 
manganiferous calc-shale, the whole being usually of a deep red 
color. The mode of occurrence is pockety, the ore being found 
in irregular masses and stringers which follow the bedding planes 
and fractures; some of these pockets are of considerable extent, 
one affording, it is said, upwards of 1,000 tons of high grade ore, 
principally pyrolusite. A very considerable proportion of all the 
ore extracted from this mine has been pyrolusite worth from $100 
to $125 per ton at the works, and containing from 85 to 95 per 
cent, of available binoxide. 
The following assays taken from an article entitled " Notes on 
the Manganese ores of Nova Scotia,"' by E. Gilpin, Jr., show 
the character of the ores obtained from Teny Cape and vicinity:

Deposits similar to that at Teny Cape have lieen worked to a 
smaller extent at Cheverie, Walton. Noel and Shulienacadie, on 
the south shore of Minas Basin, while on the north shore no im- 
portant deposits of manganese have been noted, though some of 
the limonite and other iron ores of the neighborhood of London- 
derry are highly manganiferous; this is also the case with many 
of the iron ores of both Colchester and Pictou counties. 
The following assays, taken also from Mr. Gilpins article men- 
tioned above, show the character of some of these ores, the par-
