Mr. President, I will not dwell upon other concomitant causes, all having the same tendency, and all well calculated to awaken, to arouse us--if, as I hope the fact is, we are all of us sincerely desirous of preserving this Union--to rouse us to dangers which really exist, without underrating them upon the one hand, or magnifying them upon the other. * * * It has been objected against this measure that it is a compromise. It has been said that it is a compromise of principle, or of a principle. Mr. President, what is a compromise? It is a work of mutual concession--an agreement in which there are reciprocal stipulations--a work in which, for the sake of peace and concord, one party abates his extreme demands in consideration of an abatement of extreme demands by the other party: it is a measure of mutual concession--a measure of mutual sacrifice. Undoubtedly, Mr. President, in all such measures of compromise, one party would be very glad to get what he wants, and reject what he does not desire, but which the other party wants. But when he comes to reflect that, from the nature of the Government and its operations, and from those with whom he is dealing, it is necessary upon his part, in order to secure what he wants, to grant something to the other side, he should be reconciled to the concession which he has made, in consequence of the concession which he is to receive, if there is no great principle involved, such as a violation of the Constitution of the United States. I admit that such a compromise as that ought never to be sanctioned or adopted. But I now call upon any senator in his place to point out from the beginning to the end, from California to New Mexico, a solitary provision in this bill which is violative of the Constitution of the United States.
