THE GRANTEES OF
CONNECTICUT ARE
BEST in COUNTRY
New England Granite Can
Be Found in ALI Cities
of Nation

The United States Geological Sur-
vey. Department of the Interior. has
published valuable report on The
GRANTEES OF Connecticut" copies of
which can be had on application. The
magnitude of the granite industry of
New England lends special interest
and Importance to this publication
which describes not only the geo
logic origin of the GRANTEES and their
distribution, but also the principal
features of the granite industry. New
England granite in the form of statu-
airy, monuments, bridges and build
1ngs is found in almost every part of
the United States and even in for
eign countries. In nearly all the
Eastern states, as well as in cities
as distant from New England as
Ficksburg. Spokane, and San Francis
CO, in Montreal, and in Cuba these
GRANTEES may be seen in statues or in
permanent structures
Though the GRANTEES are by no
means the oldest rocks, they furnish
by far the hardest and most dura BILE
construction stone, though they DIFF
fer greatly in hardness among them
selves. Some GRANTEES crush under a

ure exceeding 10000 pounds. The
GRANTEES are of plutonic5 origin, re-

granite rocks such as the gneisses.
These profound disturbances in earl,

New England deposits of granite anf

nomic uses ranging from statue max
ing to road building. The rocks ar,
of many colors-black. white, red
purple, pink and yellow. The au
thors of the bulletin. T. Nelson Dali
and Herbert E. Gregory, believe tina
when these GRANTEES were forne,
New England was a mountainous re
gion that stood several thousand fee
higher than the land of today. Prof
Gregory says: eve NAV be reason
ably sure that mountains of folde
strata once occupied Connecticut an
that the GRANTEES, and gneisses an
schists which. we see are but tn
stumps of lofty land masses rivalin
the Alps in height and r1ggedness."
The great cap of everything rock int
which the GRANTEES were intruded ha
since been largely removed by erosion
so that the granite is now exposed q
many places. Some conception {
the age of these rocks may be game
from the statement of the GeoIogicz

6 inch in thousand years. A goo
