Six New England States Did
in Year 1907
SAYS GEOLOGICAL SURVEY
While Three of Them, Maine, Massa-
chusetts and Vermont, Produced 40
Per Cent. of the country's
Entire Output.

Washington, d. C., Nov. 0.--The value
of the granite industry to New England
is shown by the fact that the six states
produced in 1907 approximately so per
cent. of the granite output Of the entire
country, and that three of them-Maine,
Massachusetts, and Vermont-furnished
nearly 40 per cent of it. A series of re.
ports describing the New England gran
ties from both the scientific and the eco.
nomic standpoint has been planned by
the United States Geological Survey and
two have already been published. In the
first of these, Bulletin 3l3. the GRANTEES
of Maine were discussed; in the second,
which has just been issued as Bulletin
354, the chief commercial GRANTEES Of
Massachusetts,, New Hampshire, and
Rhode Island are described. Both bulle-
tins are the work OF Prof I. Nelson
Dale, who has in preparation reports on
the remaining areas The GRANTEES dis
cussed in Bulletin 354 are chiefly those
from the quarries at Milford, Quincy,
ROckport, and Beckett NEAR Chesterl in
Massachusetts,; at Concord. Milford and
Conway, n. r.; and at Westerly, X. l.,
but certain OF those from Auburn and
Sunapee, in New Hampshire are Incl
dentally considered. Consideration Of
the GRANTEES Of Monson and Graniteville,
Mass, of Troy, n H., and of several
other places in the three states named
is reserved for later publication.
A Report for Practical Use.
Purely petrologic discussion of the
GRANTEES and associated rocks forms no
part of either Of the reports here re.
ferred TO, and the necessary scientific
descriptions have been adapted. so far
az possible, TO the general reader The
observations on the relation OF the bands
Of knots to flow structure in the granite,
on the parallelism of banding with sheet
and and rift, on the relation Of sheeting
to the surface OF the rock. and on the
spacing and distribution OF the joints
furnish data OF high scientific value
which can be used by the geologist who
is interested in the physics of intrusion.
Several of the same observations can
also be utilized by quarry superinten-
dents. For example. the value of a
quarry site is largely dependent on the
joint system, and an understanding OF
the distribution of knots or other i'm
projections in the stone will guide quarry
operations. The discussion Of the dis
eoloration called sap" also has a prae.
tical value, as we'll as the suggestion as
to the use that can be made OF granite
so discolorod.
The economic Importance Of minute
structural features, such as the great
variation in fssility, is eXemplified in
the range Of the number of paving blocks
which equally skilled workmen can make |
of different GRANTEES in one day. Thus |
at Quincy payer averages rs blocks |
a day Isle, II by 4 by inches). In
Maine the number is from so to 100 of |
New York size III to IA BY 7 by 4 /
inchesl. AT Milford, n. H., the average
number of Philadelphia size is 200, and |
at Redstone, N. H., 1870 of New York size
which is from 80 to so per cent. more
than is usual in Maine At Backet the
average is $50, size not stated.
Some Interesting Details.
In conclusion Professor Dale says:
"In reviewing the very numerous de-
tails brought together in the preceding
pages several general ideas will impress
themselves on the reader: First, the
long and complex geological history of
the rock masses which are being quar-
RED Next, the very intricate micro
scopic character of tile various GRANTEES
described, both in their mineral compost
lion and texture and in the changes
which have taken place in them Then,
llso, the great ingenuity shown in the
various mechanical devices for quarrying
he stone, and especially in the modern
machinery for working and
inishing it; and, finally, the architectural
ind sculptural skill displayed in the
structures and monuments made OF it.
Among the more notable of these made
n being made Of these GRANTEES are: The
railroad terminal at New
York, the Congressional Library the
Cambridge and Boston bridge, the Bunk.
II Hill monument, and the national mon
lment at Gettysburg"
