had been
democratic cries for securing to Polk west-northern votes in 1844. We
had, however, no valid claim so far north, except against Russia--by the
treaty of 1824. The Louisiana purchase, indeed, had vested us with
whatever--very dubious--rights France had upon the Pacific, and the
Florida treaty of 1819 gave us the far better title of Spain to the
coast north of 42 degrees. This treaty, with Gray's discovery of the
Columbia in 1792, Lewis and Clarke's official explorations of the
Columbia valley in 1804-05-06, England's retrocession, in 1818, of
Astoria, captured during the War of 1812, and extensive actual
settlements upon the river by American citizens from 1832 on, made our
claim perfect up to 49 degrees at least. This parallel the convention
with Great Britain in 1818 had already fixed as our northern line from
the Lake of Woods to the Rocky Mountains. Between this and 54 degrees 40
minutes, England's title, from exploration and settlement, was superior
to ours, which was based upon alleged old Spanish discovery. The same
convention of 1818, renewed in 1827, opened the Oregon country to
occupation by settlers from both nations. Increase of immigration
rendering a fixing of jurisdictions imperative, England pressed for the
line of the Columbia below its intersection of the forty-ninth parallel.
We had twice offered to settle upon 49 degrees, which limit the rapid
growth of our population in the region induced England in 1836 to
accept. Whether Polk's blustering demand for "all Oregon," which came
near bringing on war with England, and his much condemned recession
later, were mere opportunist acts, is still a question. Many consider
them pieces of a deep-laid policy by Polk to tole Mexico to war in hope
of England's aid, then, suddenly pacifying England, to devour Mexico at
his leisure.

CHAPTER IV.

CALIFORNIA AND THE COMPROMISE OF 1850

[1846]

One of the campaigns at the beginning of the Mexican War was that of
General Stephen W. Kearney, from Fort Leavenworth, against New Mexico.
It was opened in May, 1846. He invaded the country without much
opposition, arrived at Santa Fe August 18th, having marched 873 miles,
declared the inhabitants free from all allegiance to Mexico, and formed
a territorial government over them as United States subjects.

Captain John C. Fremont had previously, but in the same year, 1846, been
sent to California at the head of an exploring expedition, and in May he
was notif
