This Tertiary area also is divided by climatic conditions.
The south- western and western part, the "Rio Grande Plain", having a very shallow rainfall, produces only a dwarfed and shrubby natural vegetation and is hence called the "Chaparral Country"; the humid part, however, north and north-east, called the East Texas timber belt, grows both the short and long-leaf pine. In the northern part of this region more fertile soil affords the great fruit and "truck" products; cotton and tobacco are also grown.
On the west and south-west boundary the Rio Grande runs for 1200 miles.
The Pecos River crosses the western portion of the state, from north to south, without a tributary.
Extending back from the Gulf Coast for from thirty to fifty miles, an outcrop of underlying clays gives a flat, almost treeless tract running along the whole length of the coast and known as the Coast Prairie.
The first of these, nearest the coast, is called the Coastal Plain, consisting of Coast Prairies, a Tertiary area, and Black Prairies.
The chief industry of the section is the care of cattle.
Over such an etended area the drainage is naturally diverse.
On the Stockton Plateau the formation resembles that of Edward's, but the rainfall being less, averaging only fifteen inches annually, it is used almost entirely for cattle.In one part of the west of this Tertiary region cotton is cultivated, and valuable deposits of brick and pottery clays and lignite are extensively worked.Further inland and north of the Colorado River in this Coastal Plain are the Black and Grand Prairies, the most important agricultural region of Texas. The eastern and northern part, where the rainfall reaches from forty to fifty inches annually, are suitable for rice culture, which is localized there; in the central portion along the coast where the rainfall is less, sugar-cane, fruit, and "truck" are extensively cultivated, while in the southwest, with a rainfall of only 20 to 28 inches annually, cotton culture and "cattle raising on the range" are the chief industries. Different climatic conditions with respect to rainfall vary the products of different parts of this region.The western portion contains notably fertile soils, yielding abundant crops of kafir-corn, milo-maize, cotton, wheat, oats, peaches, and alfalfa.Deposits of salt, clay, and gypsum occur in this area.Local conditions have, however, retarded the mining development, and silver and quicksilver are the only ores worked on a commercial basis.The annual rainfall on these mountains is as low as ten to fifteen inches, but irrigation of the valley lands is practised by means of impounded storm-water, and alfalfa and kafir-corn are commonly grown.Black waxy calcareous clay soil, for the most part underlaid by prolific and widespread water-bearing formations, makes this region the great cotton and corn producing section, while oats, wheat, alfalfa, and sorghum are also extensively grown.Wherever the climate becomes arid cattle raising increases as an industry.
