The Thirty-first Congress was three weeks attempting an organization, and at last effected it by the election of a Southerner to the Speakership, the Hon. Howell Cobb, of Georgia. President Zachary Taylor had called the attention of Congress to the admission of California and New Mexico into the Union, in his message to that body upon its assembling. On the 4th of January, 1850, Gen. Sam. Houston, United States Senator from Texas, submitted the following proposition to the Senate:

"Whereas, The Congress of the United States, possessing only a delegated authority, has no power over the subject of negro slavery within the limits of the United States, either to prohibit or to interfere with it in the States, territories, or districts, where, by municipal law, it now exists, or to establish it in any State or territory where it does not exist; but as an assurance and guarantee to promote harmony, quiet apprehension, and remove sectional prejudice, which by possibility might impair or weaken love and devotion to the Union in any part of the country, it is hereby

"Resolved, That, as the people in territories have the same inherent rights of self-government as the people in the States, if, in the exercise of such inherent rights, the people in the newly acquired territories, by the annexation of Texas and the acquisition of California and New Mexico, south of the parallel of thirty-six degrees and thirty minutes of north latitude, extending to the Pacific Ocean, shall establish negro slavery in the formation of their State governments, it shall be deemed no objection to their admission as a State or States into the Union, in accordance with the Constitution of the United States."

On the 29th of January, Henry Clay, of Kentucky, submitted to the United States Senate the following propositions looking toward an amicable adjustment of the entire slavery question:

"1. Resolved, That California, with suitable boundaries, ought, upon her application, to be admitted as one of the States of this Union, without the imposition by Congress of any restriction in respect to the exclusion or introduction of slavery within those boundaries.

"2. Resolved, That as slavery does not exist by law, and is not likely to be introduced into any of the territory acquired by the United States from the republic of Mexico, it is inexpedient for Congress to provide by law either for its introduction into, or exclusion from, any part of the said territory; and that appropriate territorial governments ought to be established by Congress in all the said territory not assigned as within the boundaries of the proposed State of California, without the adoption of any restriction or condition on the subject of slavery.

"3. Resolved, That the western boundary of the State of Texas ought to be fixed on the Rio del Norte, commencing one marine league from its mouth, and running up that river to the southern line of New Mexico, thence with that line eastwardly, and so continuing in the same direction to the line as established between the United States and Spain, excluding any portion of New Mexico, whether lying on the east or west of that river.

"4. Resolved, That it be proposed to the State of Texas, that the United States will provide for the payment of all that portion of the legitimate and bona-fide public debt of that State contracted prior to its annexation to the United States, and for which the duties on foreign imports were pledged by the said State to its creditors, not exceeding the sum of—— dollars, in consideration of the said duties so pledged having been no longer applicable to that object after the said annexation, but having thenceforward become payable to the United States; and upon the condition, also, that the said State of Texas shall, by some solemn and authentic act of her Legislature, or of a convention, relinquish to the United States any claim which she has to any part of New Mexico.

"5. Resolved, That it is inexpedient to abolish slavery in the District of Columbia whilst that institution continues to exist in the State of Maryland, without the consent of that State, without the consent of the people of the District, and without just compensation to the owners of slaves within the District.

"6. But Resolved, That it is expedient to prohibit within the District, the slave-trade in slaves brought into it from States or places beyond the limits of the District, either to be sold therein as merchandise, or to be transported to other markets without the District of Columbia.

"7. Resolved, That more effectual provision ought to be made by law, according to the requirement of the Constitution, for the restitution and delivery of persons bound to service or labor in any State, who may escape into any other State or territory in the Union. And

"8. Resolved, That Congress has no power to prohibit or obstruct the trade in slaves between the slave-holding States, but that the admission or exclusion of slaves brought from one into another of them, depends exclusively upon their own particular laws."
