SANDSTONE

 Markets,and ' uses.—The building-sandstone industry declined about
39 percent in volume and 52 percent in value in 1932 compared with
1931. Paving blocks decreased about 29 percent in number and .17
percent in value. Figures for curbing and flagging in 1932 are not yet
available.
 Sandstone, as the name implies, results from consolidation of sand grains
into rock. It is used widely for building purposes and to a smaller. extent
for paving blocks, curbing, and flagging. The manufacture of grindstones
and pulpstones from sandstone, formerly an important industry, has declined
greatly because of increasing competition from synthetic abrasive stones~
 Sandstone may be employed in buildings for entire exteriors, colunms, steps,
and triniming. or for interior structural and decorative purposes. It is
used widely in public and private buildings and is marketed in all parts
of the country. As with other types of building stone,. recent trends are
toward the use of the rougher, seam-faced, highly colored sandstone.
 Wire saws are used successfully in making primary cuts in at least one sandstone
quarry and probably will find wider use. They are employed also in several
sandstone mills or yards for jointing blocks of stone, cutting columns, and
even for removing larger masses of stone in carving processes.

REVIEW BY STATES

 California.—The sandstone production of California, consisting principally
of rough construction stone, flagging, and rubble, in 1932 dropped to a mere
fraction of its 1931 volume.
 Connecticu&—The well-known "Portland brownstone" is the most widely
used sandstone of the State, but sales in 1932 were very small.
 Indiana..—Sandstone is quarried in Indiana a few miles south of Mitchell
in Orange County, and at St. Meinrad in Spencer County. Production was very
small in 1932, but increased activity at St. Meinrad was in prospect Tor
1933.
 Kent'ucky.—The sandstone industry of Kentucky is centered in Rowan
and Rockcastle. Counties. There was a. small increase in quantity but a decrease
in value in 1932 compared with 1931.
 New York.—Curbing, flagstones, and sajidstonepaving blOclis were produced
in small amount during 1932 in Naw York State~
 Ohio.—Ohio is the leading producer of sandstone, just as Indiana is
the leading producer of limestone. Normally the State furni~hes 50 to 60
percent of the dimension sandstOne in the United States. The principal quarries
are near Amherst, Lorain County, altlipugh important deposits are worked
at many Other p~açes in the State. All types of products are manufactured.
Building stone is fabricated in many large well-equipped mills. Production
in 1932 decre~sed 40 percent in quantity and 56 percent in value compared
with 1931.
 Pennsylvania.—Brownstone, bluestone, and many other . types of sandstone
occur in Peunsylvania, but production in 1932 was small compared with that
of the previous year.
