The question of slavery was submitted to an election of the people of Kansas on the 21st December last, in obedience to the mandate of the constitution. Here again a fair opportunity was presented to the adherents of the Topeka constitution, if they were the majority, to decide this exciting question "in their own way" and thus restore peace to the distracted Territory; but they again refused to exercise their right of popular sovereignty, and again suffered the election to pass by default.

I heartily rejoice that a wiser and better spirit prevailed among a large majority of these people on the first Monday of January, and that they did on that day vote under the Lecompton constitution for a governor and other State officers, a Member of Congress, and for members of the legislature. This election was warmly contested by the parties, and a larger vote was polled than at any previous election in the Territory. We may now reasonably hope that the revolutionary Topeka organization will be speedily and finally abandoned, and this will go far toward the final settlement of the unhappy differences in Kansas. If frauds have been committed at this election, either by one or both parties, the legislature and the people of Kansas, under their constitution, will know how to redress themselves and punish these detestable but too common crimes without any outside interference.

The people of Kansas have, then, "in their own way" and in strict accordance with the organic act, framed a constitution and State government, have submitted the all-important question of slavery to the people, and have elected a governor, a Member to represent them in Congress, members of the State legislature, and other State officers. They now ask admission into the Union under this constitution, which is republican in its form. It is for Congress to decide whether they will admit or reject the State which has thus been created. For my own part, I am decidedly in favor of its admission, and thus terminating the Kansas question. This will carry out the great principle of nonintervention recognized and sanctioned by the organic act, which declares in express language in favor of "nonintervention by Congress with slavery in the States or Territories," leaving "the people thereof perfectly free to form and regulate their domestic institutions in their own way, subject only to the Constitution of the United States." In this manner, by localizing the question of slavery and confining it to the people whom it immediately concerned, every patriot anxiously expected that this question would be banished from the halls of Congress, where it has always exerted a baneful influence throughout the whole country.

It is proper that I should briefly refer to the election held under an act of the Territorial legislature on the first Monday of January last on the Lecompton constitution. This election was held after the Territory had been prepared for admission into the Union as a sovereign State, and when no authority existed in the Territorial legislature which could possibly destroy its existence or change its character. The election, which was peaceably conducted under my instructions, involved a strange inconsistency. A large majority of the persons who voted against the Lecompton constitution were at the very same time and place recognizing its valid existence in the most solemn and authentic manner by voting under its provisions. I have yet received no official information of the result of this election.

As a question of expediency, after the right has been maintained, it may be wise to reflect upon the benefits to Kansas and to the whole country which would result from its immediate admission into the Union, as well as the disasters which may follow its rejection. Domestic peace will be the happy consequence of its admission, and that fine Territory, which has hitherto been torn by dissensions, will rapidly increase in population and wealth and speedily realize the blessings and the comforts which follow in the train of agricultural and mechanical industry. The people will then be sovereign and can regulate their own affairs in their own way. If a majority of them desire to abolish domestic slavery within the State, there is no other possible mode by which this can be effected so speedily as by prompt admission. The will of the majority is supreme and irresistible when expressed in an orderly and lawful manner. They can make and unmake constitutions at pleasure. It would be absurd to say that they can impose fetters upon their own power which they can not afterwards remove. If they could do this, they might tie their own hands for a hundred as well as for ten years. These are fundamental principles of American freedom, and are recognized, I believe, in some form or other by every State constitution; and if Congress, in the act of admission, should think proper to recognize them I can perceive no objection to such a course. This has been done emphatically in the constitution of Kansas. It declares in the bill of rights that "all political power is inherent in the people and all free governments are founded on their authority and instituted for their benefit, and therefore they have at all times an inalienable and indefeasible right to alter, reform, or abolish their form of government in such manner as they may think proper." The great State of New York is at this moment governed under a constitution framed and established in direct opposition to the mode prescribed by the previous constitution. If, therefore, the provision changing the Kansas constitution after the year 1864 could by possibility be construed into a prohibition to make such a change previous to that period, this prohibition would be wholly unavailing. The legislature already elected may at its very first session submit the question to a vote of the people whether they will or will not have a convention to amend their constitution and adopt all necessary means for giving effect to the popular will.

It has been solemnly adjudged by the highest judicial tribunal known to our laws that slavery exists in Kansas by virtue of the Constitution of the United States. Kansas is therefore at this moment as much a slave State as Georgia or South Carolina. Without this the equality of the sovereign States composing the Union would be violated and the use and enjoyment of a territory acquired by the common treasure of all the States would be closed against the people and the property of nearly half the members of the Confederacy. Slavery can therefore never be prohibited in Kansas except by means of a constitutional provision, and in no other manner can this be obtained so promptly, if a majority of the people desire it, as by admitting it into the Union under its present constitution.

On the other hand, should Congress reject the constitution under the idea of affording the disaffected in Kansas a third opportunity of prohibiting slavery in the State, which they might have done twice before if in the majority, no man can foretell the consequences.

If Congress, for the sake of those men who refused to vote for delegates to the convention when they might have excluded slavery from the constitution, and who afterwards refused to vote on the 21st December last, when they might, as they claim, have stricken slavery from the constitution, should now reject the State because slavery remains in the constitution, it is manifest that the agitation upon this dangerous subject will be renewed in a more alarming form than it has ever yet assumed.

Every patriot in the country had indulged the hope that the Kansas and Nebraska act would put a final end to the slavery agitation, at least in Congress, which had for more than twenty years convulsed the country and endangered the Union. This act involved great and fundamental principles, and if fairly carried into effect will settle the question. Should the agitation be again revived, should the people of the sister States be again estranged from each other with more than their former bitterness, this will arise from a cause, so far as the interests of Kansas are concerned, more trifling and insignificant than has ever stirred the elements of a great people into commotion. To the people of Kansas the only practical difference between admission or rejection depends simply upon the fact whether they can themselves more speedily change the present constitution if it does not accord with the will of the majority, or frame a second constitution to be submitted to Congress hereafter. Even if this were a question of mere expediency, and not of right, the small difference of time one way or the other is of not the least importance when contrasted with the evils which must necessarily result to the whole country from a revival of the slavery agitation.

In considering this question it should never be forgotten that in proportion to its insignificance, let the decision be what it may so far as it may affect the few thousand inhabitants of Kansas who have from the beginning resisted the constitution and the laws, for this very reason the rejection of the constitution will be so much the more keenly felt by the people of fourteen of the States of this Union, where slavery is recognized under the Constitution of the United States.
