Much is said by Southern people about the affection of slaves for
their masters and mistresses; and a part of it, at least, is true. A
plot for an uprising could scarcely be devised and communicated to
twenty individuals before some one of them, to save the life of a
favorite master or mistress, would divulge it. This is the rule; and
the slave revolution in Hayti was not an exception to it, but a case
occurring under peculiar circumstances,[31] The gunpowder plot of
British history, though not connected with slaves, was more in
point. In that case, only about twenty were admitted to the secret;
and yet one of them, in his anxiety to save a friend, betrayed the
plot to that friend, and, by consequence, averted the calamity.
Occasional poisonings from the kitchen, and open or stealthy
assassinations in the field, and local revolts extending to a score
or so, will continue to occur as the natural results of slavery; but
no general insurrection of slaves, as I think, can happen in this
country for a long time. Whoever much fears, or much hopes for such
an event, will be alike disappointed.

In the language of Mr. Jefferson, uttered many years ago, "It is
still in our power to direct the process of emancipation, and
deportation, peaceably, and in such slow degrees, as that the evil
will wear off insensibly; and their places be, _pari passu_, filled
up by free white laborers. If, on the contrary, it is left to force
itself on, human nature must shudder at the prospect held up."[32]

Mr. Jefferson did not mean to say, nor do I, that the power of
emancipation is in the Federal Government. He spoke of Virginia;
and, as to the power of emancipation, I speak of the slaveholding
States only. The Federal Government, however, as we insist, has the
power of restraining the extension of the institution--the power to
insure that a slave insurrection shall never occur on any American
soil which is now free from slavery.

John Brown's effort was peculiar. It was not a slave insurrection.
It was an attempt by white men to get up a revolt among slaves, in
which the slaves refused to participate. In fact, it was so absurd
that the slaves, with all their ignorance, saw p
