ish America.

When Louisiana came to us, no limit was given to it on the north, and
fifteen years had been allowed to pass without attempting to establish
one. Now, however, the boundary was declared to be a line drawn south
from the most northwestern point of the Lake of the Woods to the
forty-ninth parallel of north latitude and along this parallel to the
summit of the Rocky Mountains.

%296. Joint Occupation of Oregon.%--The country beyond the Rocky
Mountains, the Oregon country, was claimed by both England and the
United States; so it was agreed in the treaty of 1818 that for ten years
to come the country should be held in joint occupation.

%297. The Spanish Boundary Line.%--One year later (1819) the boundary
of Louisiana was completed by a treaty with Spain, which now sold us
East and West Florida for $5,000,000. Till this time we had always
claimed that Louisiana extended across Texas as far as the Rio Grande.
By the treaty this claim was given up, and the boundary became the
Sabine River from the Gulf of Mexico to 32 deg., then a north line to the
Red River; westward along this river to the 100th meridian; then
northward to the Arkansas River, and westward to its source in the Rocky
Mountains; then a north line to 42 deg., and then along that parallel to the
Pacific Ocean.[1]

%298. Russian Claims on the Pacific.%--The Oregon country was thus
restricted to 42 deg. on the south, and though it had no limit on the north
the Emperor of Russia (in 1822) undertook to fix one at 51 deg., which he
declared should be the south boundary of Alaska. Oregon was thus to
extend from 42 deg. to 51 deg., and from the Rocky Mountains to the Pacific. But
Russia had also founded a colony in California, and seemed to be
preparing to shut the United States from the Pacific coast. Against all
this John Quincy Adams, then Secretary of State, protested, telling the
Russian minister that European powers no longer had a right to plant
colonies in either North or South America.

%299. The Holy Allies and the South American Republics.%--This was a
new doctrine, and while the United States and Russia were discussing the
boundary of Oregon, it became necessary to make another declaration
regarding the rights of European powers in the two Americas.

Ever since 1793, when Washington issued his proclamation of neutrality
(p. 206), the policy of
