a, a slaveholder, while minister from the United
States to the Republic of Colombia, wrote a letter to General Simon
Bolivar, then President of that Republic, just as he was about
assuming despotic power. The letter is dated Bogota, Sept. 22, 1826.
The following is an extract.

"From a knowledge of your own disposition and present feelings, your
excellency will not be willing to believe that you could ever be
brought to an act of tyranny, or even to execute justice with
unnecessary rigor. But trust me, sir, there is nothing more
corrupting, nothing more _destructive of the noblest and finest
feelings of our nature than the exercise of unlimited power_. The man,
who in the beginning of such a career, might shudder at the idea of
taking away the life of a fellow-being, might soon have his conscience
so seared by the repetition of crime, that the agonies of his murdered
victims might become music to his soul, and the drippings of the

population--that it leads to sloth, indolence, dissipation, and vice."

Dr. THOMAS COOPER, late President of the College of South Carolina, in
a note to his edition of the "Institutes of Justinian" page 413,
says,--

"All absolute power has a direct tendency, not only to detract from
the happiness of the persons who are subject to it, but to DEPRAVE THE
GOOD QUALITIES of those who possess it..... the whole history of human
nature, in the present and every former age, will justify me in saying
that _such is the tendency of power_ on the one hand and slavery on
the other."

A South Carolina slaveholder, whose name is with the executive
committee of the Am. A.S. Society, says, in a letter, dated April 4,
1838:--

"I think it (slavery) _ruinous to the temper_ and to our spiritual

to say and to do what the Eternal G
