The acquisition of California and New Mexico, the settlement of the Oregon boundary, and the annexation of Texas, extending to the Rio Grande, are results which, combined, are of greater consequence and will add more to the strength and wealth of the nation than any which have preceded them since the adoption of the Constitution. But to effect these great results not only California, but New Mexico, must be brought under the control of regularly organized governments. The existing condition of California and of that part of New Mexico lying west of the Rio Grande and without the limits of Texas imperiously demands that Congress should at its present session organize Territorial governments over them. Upon the exchange of ratifications of the treaty of peace with Mexico, on the 30th of May last, the temporary governments which had been established over New Mexico and California by our military and naval commanders by virtue of the rights of war ceased to derive any obligatory force from that source of authority, and having been ceded to the United States, all government and control over them under the authority of Mexico had ceased to exist. Impressed with the necessity of establishing Territorial governments over them, I recommended the subject to the favorable consideration of Congress in my message communicating the ratified treaty of peace, on the 6th of July last, and invoked their action at that session. Congress adjourned without making any provision for their government. The inhabitants by the transfer of their country had become entitled to the benefit of our laws and Constitution, and yet were left without any regularly organized government. Since that time the very limited power possessed by the Executive has been exercised to preserve and protect them from the inevitable consequences of a state of anarchy. The only government which remained was that established by the military authority during the war. Regarding this to be a de facto government, and that by the presumed consent of the inhabitants it might be continued temporarily, they were advised to conform and submit to it for the short intervening period before Congress would again assemble and could legislate on the subject. The views entertained by the Executive on this point are contained in a communication of the Secretary of State dated the 7th of October last, which was forwarded for publication to California and New Mexico, a copy of which is herewith transmitted. The small military force of the Regular Army which was serving within the limits of the acquired territories at the close of the war was retained in them, and additional forces have been ordered there for the protection of the inhabitants and to preserve and secure the rights and interests of the United States. No revenue has been or could be collected at the ports in California, because Congress failed to authorize the establishment of custom-houses or the appointment of officers for that purpose.
