Mr. SUMNER. Mr. President, Ihear senators about me say. “Make your speech after the motion to reconsider has been adopted." I have no speech to make. but I wish to meet this question on the threshold, frankly and sin cerely, with my most earnest protest. I feel that the Senate will make a great mistake if they proceed to reconsider this vote. The question was amply discussed one former occasion; it was considered in every possible aspect. The condition of the Territory of Colorado was exposed; its want of population was exhibited, and its constitution having in it the word "white" was also exhibited to the Senate. On those grounds I felt it my duty then to oppose the admission of that Territory as aState Into this Union. I opposed itthen as earnestly as I could, believing it my duty as a Senator fully satisfied that it would have been a fatal mistake for us to admit it. Having acted as I did then. I feel that. I should be untrue to my selfifl let sli an o ortunity to resist the efforttointr ucet is erritoryintothe Union at this time, and under the present circumstances of the case. I hope, therefore, thatthe Senate will not proceed to reconsider the vote that, to their honor, they have already recorded. They did well when, on a formeroccasion, after a 2 days debate. by a large vote they delib erately refused to receive this Territory into the Union. Has anything occurred since to cause a change of opinion? Is there any new evidence? Are there any new facts? Is there anything which can change your responsibilities or which can make you see your duty in a new light? Has that constitution been amended? as the word “ white” been struck out of it? Why, sir, at this moment the most important practicalquestion before the country is, whether we shall dilow the word “white” to be in the constitutions of the late rebel States. Sir, with whatjust weight can you insist that the word “white” sha I be excluded from those constitutions when you yourself deliberately receive into the Union anew State which has that principle of exelusion? I say. therefore, for the sake of my country, for the sake of public tranquillity, for the sake of those fundamental prini ci ples on which so much depends, and w rich, whether as Senator orcitizen, I can never for gct l appeal to you, air, and to my associates on this floor, not to allow thisquestion to be revived. Let Colorado wait at east until she recognizes the DeclarIndep.
