He reminded them that the Missouri Compromise was a Southern measure, approved by a Southern President, on the advice of a Southern Cabinet. While in form a law, it had all the moral obligation of a solemn contract. The considerations for the perpetual exclusion of slavery in the Territories north of 36 degrees and 30 minutes were the admission of Missouri with slavery, the permission of slavery in the Territories south of 36 degrees and 30 minutes, and the admission of new States south of that line with slavery if their constitution should so provide. The North had honorably performed its contract by the admission of Missouri and prompt consent to the admission of all other slave States that had sought it. The South had yielded nothing to the North under the contract, except the admission of Iowa and the organization of Minnesota. The slave States, having received all the contemplated benefits under the contract and yielded none, proposed to declare it ended without the consent of the free States. He closed with an appeal to the honor of the South, earnestly imploring the Senators to reject the bill as a violation of the plighted faith and solemn compact which their fathers had made and which they were bound by every sacred obligation faithfully to maintain. Seward, speaking on the 17th cautioned them that the repeal of the Compromise would be the destruction of the equilibrium between the North and the South so long maintained, the loss of which would be the wreck of the Union. He warned the North that if this territory was surrendered to slavery the South would be vested with permanent control of the Government; for every branch of it would be securely within its power. Already it had absolute sway. One slave-holder in a new Territory, with access to the Executive ear at Washington, exercised more political influence than five hundred free men. The recital of an old repeal was made for the demagogic purpose of confusing the people, but was false in fact and false in law. The Missouri Compromise was a purely local act. That of 1850 was likewise local. They affected entirely different localities. Hence the later law could not by implication repeal the former. It was an ingenious device to attain the desired end by declaring that done by a former Congress which no one then thought of doing, and which the present Congress dared not boldly do. The doctrine of popular sovereignty meant that the Federal Government should abandon its constitutional duty and abdicate its power over he Territory in favor of the first band of squatters who settled within it. It meant that the interested cupidity of the first chance settlers was more fit to guide the destinies of the infant Territory than the collective wisdom of the American people.
