The Highfield outcrop shows that the ore beds lie in this Shaw range, 
at a much gentler angle than in the Tuscarora range ; thus :— 
Fie. 14. 
The distribution of pieces of ore over wide sections of the outcrop of 
the ore-belt, is a notable thing. Along certain narrow lines inside 
the belt, are to be seen multitudes of fragments lying on the ground, 
which have been left behind when the rest of the rock has been mould- 
ered and washed away. And sometimes these fragments are a foot or 
more in diameter, although commonly smaller. Formerly, the ground 
was abundantly covered with them, but they were the first ore sought 
and used, and most of the large pieces and patches have disappeared du- 
ring the war years of 1861, ’2, ’8 and ’4. 4 
Large pieces on the surface are the best evidence we can possess (in the 
ease of unexplored ground) that the beds are of a good size, for they 
have come from those portions of the beds (a,b, c, &e., in the accompa- 
nying diagram, (fig.15), which have been destroyed in the general lowering 
of the surface of the country. “There is no reason why the parts of the ! 
beds left under the present surface (a/, b’, ec’, &e.), should not yield as 
large masses as the parts a, b, c, which have been mouldered away. 
2. The Size of the Ore Beds varies as much as their number. They con- 
sist of strings of lens-shaped masses, continually enlarging and contract- 
ing in thickness, from a féw inches to six and eight feet. The principal 
beds may be safely estimated on an average of four feet, or 176,000 tons 
to the mile, with an average breasting of 60 feet above water level. Itis 
needless to say that an equal amount would exist beneath water-level, 
for every sixty feet sunk on the bed. 
3. The Quality of the Ore.—It belongs to the family of the Primary Ores. 
It is very similar to the New Jersey ores which are so extensively
