THE TEXAS ALMANAC.
sizable mineral production, for more than
$50,000,000 annually comes from minerals
other than petroleum. There is a large
production of sulphur, natural gas, coal
and lignite, clay products, cement mate-
rials, salt, lime iand limestone, granite,
sandstone, marble, silver and quicksilver.
In 1890 the total mineral pIroduction of
Texas was given at $1,992,803; in 1900, it
was $5,316,222; in 1910 it was $18,383,451;
in 1920 it was $371,250,979. Although the
1920 figure was the highest yet recorded
-due princil>aly to the very high price of
petroleum throughout most of this year-
yet Texas mineral production has not
fallen below $200,000,0(00 since 1920 and
during the last thrce years has climbed
back above the $300,o000,000 mark.
Phy siographll ic Aspects.
Texas has a coast line of about 370
miles (with tidal shore line of about 624
miles), the third longest among the
States. From this long coast line the
surface slopes gradually upward toward
the north, no rthil est and west. reaching
its highest elevations in the broad level
plains of the P'anhan dle region, which
range generally from 3,000 to 4,000 feet
above sea level, and in the mountainous
region of the Trans-Pecos, where the
plateau approximates that of the Pan-
handle in general elevation, but with
mountains rising above it and ranging in
altitude as high as 7,500 Meet in several
instances and 9,500 in one, Guadalupe
peak, the highest nmoruntain in Texas.
The surface is drained by some sixteen
different primary watersheds, as general-
ly classified in t(opographic surveys, but
most of the water flows to the Gulf
through the i ed, which emlpties into the
Mississippi, and the Salbine, Neches, Trin-
ity, Brazos, ('Colorado, (Guadalupe, San An-
tonio, Nueces anld Rio( G'rande challlnnels,
all of which flow directly into the Gulf.
Great coastal l Plain,
The greatest physirig raphic division of
Texas is the great coastal plain. It ex-
tends from the lower Rio Grande to the
Red River in Northeast Texas, cover-
ing all territory east and south of the
great lalcones fault from the approxi-
mate location of Del Rio eastward to San
Antonio, thence northeastward, passing
near Austin and a short distance east of
Waco and Dallas. This great territory,
however, while generally classified as a
coastal plain, has marked physical sub-
LoNer Coastal Plain.
Immediately along the coast and ex-
tending inland from 50 to 100 miles is
what may be called the immediate coastal
plain. Its elevation ranges from sea level
to 100 or 200 feet and it is comparatively
level and generally without heavy timber
except along the channels of the streams
which cross it. However, much mesquite
and huisache are found in that section be-
low Corpus Christi, a good deal of live
oak and postoak and other hardwoods
from Corpus Christi to Houston and some
pine around and east of Houston, al-
though this lower level of the coastal
plain skirts the lower end of the main
pine belt of Texas.
The soil is generally alluvial, varying
from loams to tight, black clays. It is fer-
tile, but in the eastern portion drainage
is needed before a large portion can be
The rainfall varies from about twenty-
five inches annually along the Rio Grande
in the extreme southern and western end
of this belt to approximately forty-three
inches in the vicinity of IBeaumont in the
extreme eastern end. The great irrigated
area of the lower Rio Grande Valley, the
"Magic Valley," lies in the extreme lower
end. It is one of the major winter and
early spring vegetable producing areas of
the U(nited States and a large citrus grow-
ing industry is developing. Much cotton
is grown throughout this belt, especially
in the Rio Grande Valley, where it is
grown principally under irrigation, and in
the vicinity of Corpus Christi, where it is

part in the settlement of T'rexas. It has been replaced largely by rail and motor vehicle
transportation. but it is still seen occasionally along the Texas highways. This pic-
