light metal extraction, bromine, graphite, natural salines, and sulfur. One
of the major problems of the economy has been the relatively small development
of consumer-oriented industries within the State. 
 Several industries were integrated to convert raw materials into intermediates
or finished products for both State and national markets. Such industries
included oil refineries processing domestic and foreign crude oil; cement
plants using local limestone, shell, and clay; and building materials manufacturers
using gypsum to prepare wallboard, sheathing, and plaster. The petrochemical
industry of the gulf coast produced a major portion of the domestic feedstocks—ethylene,
propylene, and butylene—for numerous syn 
thetic chemical plastics, fibers, and solvents. The feedstocks were derived
from natural gas, natural gas liquids, and refinery off-gases. Nearly 300
chemical plants operated in Texas in 1967, producing over 500 chemical intermediates
and other synthetic products. 
 
 Legislative and Government Programs.— The State of Texas' claim to
about 30,000 acres of potentially valuable oil land in the Gulf of Mexico
was denied by the Supreme Court. The State's position was that the 3-league
(9 nautical miles) distance should be measured from the tip of manmade jetties
rather than the natural coastline of 1845, the year Texas joined the Union,
as contended by the Government. The Texas contention would have
