_To the Senate of the United States_: I transmit for the approval of the Senate an informal convention with the Republic of Venezuela for the adjustment of claims of citizens of the United States on the Government of that Republic growing out of their forcible expulsion by Venezuelan authorities from the guano island of Aves, in the Caribbean Sea. Usually it is not deemed necessary to consult the Senate in regard to similar instruments relating to private claims of small amount when the aggrieved parties are satisfied with their terms. In this instance, however, although the convention was negotiated under the authority of the Venezuelan Executive and has been approved by the National Convention of that Republic, there is some reason to apprehend that, owing to the frequent changes in that Government, the payments for which it provides may be refused or delayed upon the pretext that the instrument has not received the constitutional sanction of this Government. It is understood that if the payments adverted to shall be made as stipulated the convention will be acceptable to the claimants. JAMES BUCHANAN. WASHINGTON, _February 9, 1860_. _To the Senate of the United States_: I transmit to the Senate, for its consideration with a view to ratification, a treaty of peace, friendship, commerce, and navigation between the United States and the Republic of Bolivia, signed by their respective plenipotentiaries at La Paz on the 13th of May, 1858. JAMES BUCHANAN. WASHINGTON, _February 20, 1860_. _To the Senate and House of Representatives of the United States_: Eight memorials numerously signed by our fellow-citizens, "residents for the most part within the territorial limits of Kansas and Nebraska at and near the eastern slope of the Rocky Mountains," have been presented to me, containing the request that I would submit the condition of the memorialists to the two Houses of Congress in a special message. Accordingly, I transmit four of these memorials to the Senate and four to the House of Representatives. These memorialists invoke the interposition of Congress and of the Executive "for the early extinguishment of the Indian title, a consequent survey and sale of the public land, and the establishment of an assay office in the immediate and daily reach of the citizens of that region." They also urge "the erection of a new Territory from contiguous portions of New Mexico, Utah, Kansas, and Nebraska," with the boundaries set forth in their memorial. They further state, if this request should not be granted, "that (inasmuch as during this year a census is to be taken) an enabling act be passed with provision upon condition that if on the 1st day of July, 1860, 30,000 resident inhabitants be found within the limits of the mineral region, then a Territorial government is constituted by Executive proclamation; or if on the 1st day of September, 1860, 150,000 shall be returned, then a State organization to occur."
