which occur in the Fayette beds (coast region,
from the Sabine to the Rio Grande,
and from 40 to 150 miles wide); the eroded
flints of the Cretaceous; some of the firmer
limnestones of the lower divisions of the Cretaceous
and the Carboniferous areas; the
basalt of such areas as Pilot Knob in Travis
county; some of thle sandstones or siliceous
iron ores of the iron region of east Texas;
the granites and other tough rocks of the
central region are especially valuable, and
similar rocks and the quartzites and porphyries
of west Texas will also prove of
value when transportation charges will admit
of their use.
The occurrence of asphaltum in various
portions of the State has already boen noticed,
and its use as paving material is well known.
For the construction of sidewalks, in addition
to the material above mentioned, flagstones
are found in various localities.
MATERIALS FOR PAINTS.
Grcphite has already been mentioned under
Ochre is a hydrated oxide of iron, usually
containing more or less clay or sand and
giving various shades of yellow, red and
brown, The most valuable is that which on
preparation furnishes the color called Indian
red. Ochres are found in connection with
the geode and nodular ores of east Texas,
forming centers of the geodes, and also deposits
of limited extent. It is reported at
many localities in the area covered by the
timber-belt beds. In the .Cretaceous area
good ochres occur in Uvalde and Val Verde
counties, in the latter of which one locality
has been developed to some extent and the
material slipped. Other deposits have been
opened and worked very slightly for local
use in different parts of the State.
Baryteas is found in Llaro county, but has
not been put to any use at all as yet.

Sulphzur.- Specimens of native sulphur of
a high degree of purity have been received
from Edwards county, but up) to the present
no detailed examination has been made to
ascertain its quantity or the condition of its
Saflt.-Like many of the other valuable deposits
of Texas, the occurrence of common ,-alt
is widespread. Along the coast to the southwest
are lagoons or salt lakes from which
large amounts of salt are taken annually.
Besides the lakes along the shore many others
occur through western Texas, reaching to
the New Mexico line, while northeast of
these in thie Permian region the constant
recurrence of such names as Salt fork, Salt
creek, etc., tell of the prevalence of similar
conditions. In addition to tie lakes and
creeks from which salt is secured bly solar
evaporation we have also extensive bleds of
That which is at present best developed is
located in the vicinity of Colorado City, in
Mitchell county. Thle bed of salt was found
by boring at 850 feet, and proved to have a
thickness of 140 feet. A vein of water was
struck below it which rises to within 150
feet of the surface. This is pumped to the
surface and evaporated, and the resulting
salt purified for commerce.
In eastern Texas there have long been
known low pieces of ground called "salines,"
at which salt has been manufactured by sinking
shallow wells and evaporating the water
taken from them. At one of these, Grand
