northern
Democracy, have left us to fulfil; and I, for one, mean to fulfil it,
because I will not violate the faith of the Government. What I mean
to say is, that the time for the admission of new States formed out of
Texas, the number of such States, their boundaries, the requisite amount
of population, and all other things connected with the admission, are
in the free discretion of Congress, except this: to wit, that when new
States formed out of Texas are to be admitted, they have a right, by
legal stipulation and contract, to come in as slave States.

Now, as to California and New Mexico, I hold slavery to be excluded
from these territories by a law even superior to that which admits and
sanctions it in Texas. I mean the law of nature, of physical geography,
the law of the formation of the earth. That law settles forever, with a
strength beyond all terms of human enactment, that slavery cannot exist
in California or New Mexico. Understand me, sir; I mean slavery as we
regard it; the slavery of the colored race as it exists in the southern
States. I shall not discuss the point, but leave it to the learned
gentlemen who have undertaken to discuss it; but I suppose there is
no slavery of that description in California now. I understand that
peonism, a sort of penal servitude, exists there, or rather a sort of
voluntary sale of a man and his offspring for debt, an arrangement of a
peculiar nature known to the law of Mexico. But what I mean to say
is, that it is impossible that African slavery, as we see it among us,
should find its way, or be introduced, into California and New Mexico,
as any other natural impossibility. California and New Mexico are
Asiatic in their formation and scenery. They are composed of vast ridges
of mountains of great height, with broken ridges and deep valleys.
The sides of these mountains are entirely barren; their tops capped
by perennial snow. There may be in California, now made free by its
constitution, and no doubt there are, some tracts of valuable land.
But it is not so in New Mexico. Pray, what is the evidence which every
gentleman must have obtained on this subject, from information sought by
himself or communicated by others? I have inquired and read all I could
find, in order to acquire information on this important subject. What is
there in New Mexico that could, by any possibility, induce anybody to go
there with slaves! There are some narrow strips of tillable land on the
border
