nd they would have said it if they had meant it. An
intention to extend the law is not only not mentioned in the law, but is
not mentioned in any contemporaneous history. Both the law itself, and the
history of the times, are a blank as to any principle of extension; and
by neither the known rules of construing statutes and contracts, nor by
common sense, can any such principle be inferred.

Another fact showing the specific character of the Missouri law--showing
that it intended no more than it expressed, showing that the line was not
intended as a universal dividing line between Free and Slave territory,
present and prospective, north of which slavery could never go--is the
fact that by that very law Missouri came in as a slave State, north of the
line. If that law contained any prospective principle, the whole law must
be looked to in order to ascertain what the principle was. And by this
rule the South could fairly contend that, inasmuch as they got one slave
State north of the line at the inception of the law, they have the right
to have another given them north of it occasionally, now and then, in the
indefinite westward extension of the line. This demonstrates the absurdity
of attempting to deduce a prospective principle from the Missouri
Compromise line.

When we voted for the Wilmot Proviso we were voting to keep slavery out
of the whole Mexican acquisition, and little did we think we were thereby
voting to let it into Nebraska lying several hundred miles distant. When
we voted against extending the Missouri line, little did we think we were
voting to destroy the old line, then of near thirty years' standing.

To argue that we thus repudiated the Missouri Compromise is no less absurd
than it would be to argue that because we have so far forborne to acquire
Cuba, we have thereby, in principle, repudiated our former acquisitions
and determined to throw them out of the Union. No less absurd than it
would be to say that because I may have refused to build an addition to
my house, I thereby have decided to destroy the existing house! And if
I catch you setting fire to my house, you will turn upon me and say I
instructed you to do it!

The most conclusive argument, however, that while for the Wilmot Proviso,
and while voting against the extension of the Missouri line, we never
thought of disturbing the original Missouri Compromise, is found in the
fact that there was then, and still is, an unorganized tract of fine
