The Expedition has executed every part of the duties confided to it
by the Government. A long list of ports, harbors, islands, reefs,
and shoals, named in the list, have been visited and examined or
surveyed. The positions assigned on the charts to several vigias,
reefs, shoals, and islands, have been carefully looked for, run over,
and found to have no existence in or near the places assigned them.
Several of the principal groups and islands in the Pacific Ocean have
been visited, examined, and surveyed; and friendly intercourse, and
protective commercial regulations, established with the chiefs and
natives. The discoveries in the Antarctic Ocean (Antarctic
continent, -- Observations for fixing the Southern Magnetic pole,
&c.) _preceded_ those of the French and English expeditions. The
Expedition, during its absence, has also examined and surveyed a
large portion of the Oregon Territory, a part of Upper California,
including the Columbia and Sacramento Rivers, with their various
tributaries. Several exploring parties from the Squadron have
explored, examined, and fixed those portions of the Oregon Territory
least known.
