Manganese in Canada. — Brnniell. 87 
Manj^ other deposits, both of crystalline ores and wad, are 
known to exist throughout the island. One of these on Boular- 
derie island is said to lie quite extensive, and the character of the 
ore may he judged from the following assays: 
Manganese per xide 
Iron sesquioxide 
Insoluble matter

Ontario an.d Qifeliec. — Outside of Nova Scotia and New Bruns- 
wick but little manganese is known to occur, and where noted is 
usually of low grade. In Quebec several small deposits of wad 
have been noted, the largest, perhaps, being that in Stanshead 
township, where on lot nine, range ten, the ore covers an area of 
about twenty acres, and has a thickness of about twelve inches. 
That this deposit has but slight commercial value is evidenced by 
the fact that the washed ore contains only 87% of peroxide. 
Another deposit, similar to the above, occurs on lot twenty, range 
twelve of Bolton, the ore there assaying 26% . Many similar 
deposits might be mentioned, though probably none as imi)ortant 
as those noticed above. 
Manganese has also l)een noted as occurring on the Magdalen 
islands, a small group in the gulf of St. Lawrence. Of these, 
deposits Mr. Jas. Richardson in the report of the Geological Sur- 
vey 1879-80, writes: •Immediately under Demoiselle hill, on 
Amherst island, numerous l)locks charged with peroxide of man- 
ganese, or pyrolusite, occur among the debris of the fallen cliffs. 
Thej' are in pieces varying from one pound to ten or fifteen 
pounds in weight. There can be little doubt that they are de- 
rived from a deposit more or less regular in the hill side, Init 
which is now completely concealed by the fallen debris. At a 
place bearing nearly due west from Cap aux Meules, at a distance 
of about a mile, and close to the English Mission church, similar 
pieces to those above described are verv frequently i)icked up. 
Assays of this ore, in the same volume, gave:

In Ontario manganese has been reported from Batehewaherung 
bay, lake Superior. The ore is manganite and is said to assay as
