His conclusions were irresistibly convincing.
The sum of the whole is [said he] that of our thirty-nine fathers who framed the original Constitution, twenty-one--a clear majority of the whole--certainly understood that no proper division of local from Federal authority, nor any part of the Constitution, forbade the Federal Government to control as to slavery in the Federal Territories; while all the rest probably had the same understanding.

Such unquestionably was the understanding of our fathers who framed the original Constitution; and the text affirms that they understood the question "better than we"....

It is surely safe to assume that the thirty-nine framers of the original Constitution and the seventy-six members of the Congress which framed the amendments thereto, taken together, do certainly include those who may be fairly called "our fathers who framed the Government under which we live." And so assuming, I defy any man to show that any one of them ever, in his whole life, declared that in his understanding any proper division of local from Federal authority, or any part of the Constitution, forbade the Federal Government to control as to slavery in the Federal Territories.

I go a step further.

I defy any one to show that any living man in the whole world ever did, prior to the beginning of the present century (and I might almost say prior to the beginning of the last half of the present century), declare that in his understanding any proper division of local from Federal authority, or any part of the Constitution, forbade the Federal Government to control as to slavery in the Federal Territories.
