: Urban neighborhoods occupied, principally, by lower-class Mexican
Americans. Spanish language dominates in the barrio, and businesses, churches, and
other social institutions catering to Mexican Americans are concentrated in these
neighborhoods. Barrios were often, but not always, located on the fringe of the
city.
frontier
: In the American sense, an unexplored, unsettled, or recently settled
geographic region. The term also refers to any endeavor in which development possibilities
seem unbounded--for instance, the urban frontier, frontiers of science. In the European
sense, the frontier is the area near the border with another nation.
placer
mining: The process of removing gold from the sand and gravel
of stream beds. Gold, eroded from mountain lodes, washes into swift-flowing streams and is
suspended in the water until the streams slow in certain places and the gold settles to
the bottom. Placer mining is the easiest and cheapest method of gold mining because only a
simple pan or wooden sluice box is required to separate the gold from the sand and gravel.
quartz
mining: The process of removing gold or silver from lodes in
ore-bearing rock and earth. It is an expensive process involving digging, blasting,
crushing, and smelting.
territory
:A geographical and governmental subdivision under the jurisdiction
of the United States but not included within any state. Beginning with the Northwest
Ordinance of 1787, the federal government divided the West into territories to facilitate
control until the area was prepared for statehood. Territories were allowed some
self-government by territorial legislatures, but the president appointed the territorial
governor. Because of the peculiar circumstances surrounding their entry into the union,
Texas and California never went through the territorial stage.
