there are no asslgnable limits to the possible
production Of iron at Bartlet. TIE relus-
ton of the ore to iron BY charcoal, Is limited
only by the extent of, the adjacent, forests
which are vast, and likely to be permanent,
rom the character of a large proportion of
that country, which is mountainous and in
practicable forsettlement.
But this ore may not only be reduced to iron
on the spot, by the use of charcoal, but may
iron here, by the use of the waterborre Goals
of Pennsylvania and the Brthish Provinces.
If the ores of Lake Superior can the freighted
to Cleveland, Ohio aud then reduced to iron by
the use of of Goals brought up from Pittsburg,
these Bartlett ores can proftably be brought
seventy miles by rail to deep water in Port
land, here to be rednced to the metallic con-
dition.
1t may seem extravagant to say SO, but the
| future may prove that the iron of Bartlett
alone, was a sufficient object for the con-
struction of a railroad to that point. 1t is, in
| fact, impossible to foresee all the commercial
consequences to Portland, direct and indirect,
of the full development of that rich and iuex-
haustabe mass Of mineral .5e r.h
We append some extracts from Dr. Jack
sons report upon the geology of New Hamp-
| shire, printed by order of that State in 1874,
At that time the cheapest transportation
of the Bartlett ore or of the iron produced
from it, was thirty miles by Wagon to Bridg-
ton, and thence by Sebago Lake and the
Cumberland and Oxford canal to this city.

Rocky branch OF the Saco and Ellis river, in
Bartlett, hear the south line of jackson
Baldtace mountain is composed of granite
having few dykes of greensboro trap cutting
through its midst. The elevation at which
the iron ore occurs is 1404 feet above the
Rocky branch of the Saco, and about
one mile distant The slope of the noun.

Since my first visit, which was rIade fonl

One CT the mines at the upper opening
measures 81 feet in width in an East and
West direction, and 16 feet .in North and
South direction. 2 'H9,f .---.-
The second opening, 200 feet lower down
the slope of the hill, exposes the ore, maintain
| ingthe same width. Three hundred feet low
/ er down, the vein is observed to narrow, and
is but ten feet wide, and 400 feet further
down the width increases to 30 feet orr -..s
Five hundred and forty six feet lower still,
there is small opeulng or cave, 20 feet deep,
when the ore narrows again. '-ii'.ib s-'j =
/ On searching to the westward of this great
vein, at the dis ance OF $50 feet, we soon dis
coverd a new one, which appears to be of
large dimensions, but we were unable to un-
cover it sufficiently to determine its width.
Forty-sevenf feet farther westward, the soil
is full of angular fragments of the ore, indi-
eating another vein. .s..

| 1t is difficult in the present condition of the
veins, to ascertain the precise condition OF
the veins since their walls are not exposed fol
sufficient distance to furnish the requis lite

indicates the direction to be nearly N 37o E.

From the composition of the ore we know
that it will make excellent iron, and the best
kind of steel. A small proportion of manga

| The iron ore on Baldface mountain in Bart

mixture of the peroxide and protoxide of iron,
the former largely predominatmg, so as to

We may therefore calculate upon at least 48

smelling operations of blast furnace. a.

jackson, noticing some veins of magnetic
iron ore, not sufficient for blast furnace, in the
adjoining town of jackson, says of them, that
they will be valuable as contribution to the
ores OF Baldface mountain, when those great
veins are wrought, since it is an advantage to
mix several varieties of ore, this mixture serv-
ing to render the Stag more fusible." 81 70
