There were but two centres of population in Louisiana, New Orleans and
St. Louis. When the southern district, around New Orleans, applied for
admission as the slave State of Louisiana, there seems to have been no
surprise or opposition on this score; the Federalist opposition to the
admission is exactly represented by Quincy's speech in the first volume.
When the northern district, around St. Louis, applied for admission as
the slave State of Missouri, the inevitable consequences of the act
of 1804 became evident for the first time, and all the Northern States
united to resist the admission. The North controlled the House
of Representatives, and the South the Senate; and, after a severe
parliamentary struggle, the two bodies united in the compromise of 1820.
By its terms Missouri was admitted as a slave State, and slavery was
forever forbidden in the rest of Louisiana Territory, north of latitude
36° 30' (the line of the southerly boundary of Missouri). The instinct
of this first struggle against slavery extension seems to have been
much the same as that of 1846-60 the realization that a permission to
introduce slavery by custom into the Territories meant the formation
of slave States exclusively, the restriction of the free States to
the district between the Mississippi and the Atlantic, and the final
conversion of the mass of the United States to a policy of enslavement
of labor. But, on the surface, it was so entirely a struggle for the
balance of power between the two sections, that it has not seemed worth
while to introduce any of the few reported speeches of the time. The
topic is more fully and fairly discussed in the subsequent debates on
the Kansas-Nebraska Act.

In 1830 William Lloyd Garrison, a Boston printer, opened the real
anti-slavery struggle. Up to this time the anti-slavery sentiment, North
and South, had been content with the notion of "gradual abolition,"
