This ann is extremely rich in iron ores, and other me- 
_ have also nny found. The most extensive deposits of 
At Neat the ore was first dincowerail on a hill, ‘elevated 
perhaps 600 feet above the level of the sea, and about eight 
miles from the Bay of Fundy. It constitutes a regular vein, 
traversing clay = running nearly ina N. E. and S. W. 
direction. On removing the stratum of earth which covers 
the vein, and pares of a clayey ferruginons soil, about two 
feet thick, tte naked ore rene itself to vi is transversely 
top; but as the walls incline from a perpendicular outwards, 
the width increases as the mining operations advance ; so that 
I found, at the depth of 4 feet, a difference in width of 43 
inches. In some places the substance of the vein is to be 
observed mixed with, and passing into, that of the walls or 
matrix. 
Being present when the ore was ral ised, [ observed a re- 
markable stadeney-¥ which it has of breaking into rhomboidal 
circumstance which much facilitates the mining 
- Jabour. When broken, it is found completely filled with, or, 
as it were, made up of, marine shells, exhibiting impressions 
of terebratulae. In one specimen I found half of an original 
shell, perfectly white and unbroken. The slate also exhibits 
these impressions, especially when in immediate contact with 
the ore, so as to receive one half of each shell. This ore is 
hard a1 and an magr gnetic, secs some. - specimens give a

Pe The ore at C Setoent 3 is situated on land supposed | to be 
400 feet above the level of the sea. It forms a vein or bed, 
and, like the other, runs in a N, E. and S. W.. direction, 
traversing 2 hard clay slate ; but as there are no distinct 
seams of separation between the ore and walls, its exact 
width cannot be easily ascertained : it is, apparently, how- 
ever, as much as 10 feet. Large masses of ore, of many: 
tons weight, are seattered over the surface, in the neighbour- 
hood of the vein, and do not appear to differ essentially from 
it. This ore is fine granular, extremely bard, magnetic 
compact, without any seams. The impressions of shells are
