"6th. What are your views, not only as to the constitutional right of Congress to prohibit the slave-trade between the States, but also as to the expediency of exercising that right immediately?"
CAMPBELL'S REPLY.
"To the first and second interrogatories, I answer unequivocally in the affirmative.
"To the third interrogatory I reply, that I am opposed to the admission of any more Slave States into the Union, that may be formed out of Texas or any other Territory.
"To the fourth and fifth interrogatories I unhesitatingly answer in the affirmative.
"To the sixth interrogatory I reply, that so long as the Slave States continue to treat slaves as articles of commerce, the Constitution confers power on Congress to pass laws regulating that peculiar COMMERCE, and that the protection of Human Rights imperatively demands the interposition of every constitutional means to prevent this most inhuman and iniquitous traffic.
"T. CAMPBELL."
I want to say here that Thompson Campbell was elected to Congress on that platform, as the Democratic candidate in the Galena District, against Martin P. Sweet.
[Judge DOUGLAS: Give me the date of the letter.]
