He tries to persuade us that there must be a variety in the different
institutions of the States of the Union; that that variety necessarily
proceeds from the variety of soil, climate, of the face of the country,
and the difference in the natural features of the States. I agree to all
that. Have these very matters ever produced any difficulty amongst us?
Not at all. Have we ever had any quarrel over the fact that they have

house and sustain the Union.

But has it been so with this element of slavery? Have we not always had
quarrels and difficulties over it? And when will we cease to have
quarrels over it? Like causes produce like effects. It is worth while to
observe that we have generally had comparative peace upon the slavery
question, and that there has been no cause for alarm until it was excited
by the effort to spread it into new territory. Whenever it has been
limited to its present bounds, and there has been no effort to spread it,
there has been peace. All the trouble and convulsion has proceeded from
efforts to spread it over more territory. It was thus at the date of the
Missouri Compromise. It was so again with the annexation of Texas; so
with the territory acquired by the Mexican war; and it is so now.
Whenever there has been an effort to spread it, there has been agitation
and resistance. Now, I appeal to this audience (very few of whom are my
political friends), as national men, whether we have reason to expect
that the agitation in regard to this subject will cease while the causes
that tend to reproduce agitation are actively at work? Will not the same
