In pursuance of the act of the 14th of August last, extending the benefit of our post-office laws to the people of California, the Postmaster-General has appointed two agents, who have proceeded, the one to California and the other to Oregon, with authority to make the necessary arrangements for carrying its provisions into effect.

The monthly line of mail steamers from Panama to Astoria has been required to "stop and deliver and take mails at San Diego, Monterey, and San Francisco." These mail steamers, connected by the Isthmus of Panama with the line of mail steamers on the Atlantic between New York and Chagres, will establish a regular mail communication with California.

It is our solemn duty to provide with the least practicable delay for New Mexico and California regularly organized Territorial governments. The causes of the failure to do this at the last session of Congress are well known and deeply to be regretted. With the opening prospects of increased prosperity and national greatness which the acquisition of these rich and extensive territorial possessions affords, how irrational it would be to forego or to reject these advantages by the agitation of a domestic question which is coeval with the existence of our Government itself, and to endanger by internal strifes, geographical divisions, and heated contests for political power, or for any other cause, the harmony of the glorious Union of our confederated States-that Union which binds us together as one people, and which for sixty years has been our shield and protection against every danger. In the eyes of the world and of posterity how trivial and insignificant will be all our internal divisions and struggles compared with the preservation of this Union of the States in all its vigor and with all its countless blessings! No patriot would foment and excite geographical and sectional divisions. No lover of his country would deliberately calculate the value of the Union. Future generations would look in amazement upon the folly of such Other nations at the present day would look upon it with astonishment, and such of them as desire to maintain and perpetuate thrones and monarchical or aristocratical principles will view it with exultation and delight, because in it they will see the elements of faction, which they hope must ultimately overturn our system. Ours is the great example of a prosperous and free self-governed republic, commanding the admiration and the imitation of all the lovers of freedom throughout the world. How solemn, therefore, is the duty, how impressive the call upon us and upon all parts of our country, to cultivate a patriotic spirit of harmony, of good-fellowship, of compromise and mutual concession, in the administration of the incomparable system of government formed by our fathers in the midst of almost insuperable difficulties, and transmitted to us with the injunction that we should enjoy its blessings and hand it down unimpaired to those who may come after us. In view of the high and responsible duties which we owe to ourselves

a course.

and to mankind, I trust you may be able at your present session to approach the adjustment of the only domestic question which seriously threatens, or probably ever can threaten, to disturb the harmony and successful operations of our system.

The immensely valuable possessions of New Mexico and California are already inhabited by a considerable population. Attracted by their great fertility, their mineral wealth, their commercial advantages, and the salubrity of the climate, emigrants from the older States in great numbers are already preparing to seek new homes in these inviting regions. Shall the dissimilarity of the domestic institutions in the different States prevent us from providing for them suitable governments? These institutions existed at the adoption of the Constitution, but the obstacles which they interposed were overcome by that spirit of compromise which is now invoked. In a conflict of opinions or of interests, real or imaginary, between different sections of our country, neither can justly demand all which it might desire to obtain. Each, in the true spirit of our institutions, should concede something to the other.

Our gallant forces in the Mexican war, by whose patriotism and unparalleled deeds of arms we obtained these possessions as an indemnity for our just demands against Mexico, were composed of citizens who belonged to no one State or section of our Union. They were men from slaveholding and nonslaveholding States, from the North and the South, from the East and the West. They were all companions in arms and fellowcitizens of the same common country, engaged in the same common

When prosecuting that war they were brethren and friends, and shared alike with each other common toils, dangers, and sufferings. Now, when their work is ended, when peace is restored, and they return again to their homes, put off the habiliments of war, take their places in society, and resume their pursuits in civil life, surely a spirit of harmony and concession and of equal regard for the rights of all and of all sections of the Union ought to prevail in providing governments for the acquired territories-the fruits of their common service. The whole people of the United States, and of every State, contributed to defray the expenses of that war, and it would not be just for any one section to exclude another from all participation in the acquired territory. This would not be in consonance with the just system of government which the framers of the Constitution adopted.

The question is believed to be rather abstract than practical, whether slavery ever can or would exist in any portion of the acquired territory even if it were left to the option of the slaveholding States themselves. From the nature of the climate and productions in much the larger portion of it it is certain it could never exist, and in the remainder the probabilities are it would not. But however this may be, the question, involving, as it does, a principle of equality of rights of the separate and several States as equal copartners in the Confederacy, should not be disregarded.

In organizing governments over these territories no duty imposed on Congress by the Constitution requires that they should legislate on the subject of slavery, while their power to do so is not only seriously questioned, but denied by many of the soundest expounders of that instrument. Whether Congress shall legislate or not, the people of the acquired territories, when assembled in convention to form State constitutions, will possess the sole and exclusive power to determine for themselves whether slavery shall or shall not exist within their limits. If Congress shall abstain from interfering with the question, the people of these territories will be left free to adjust it as they may think proper when they apply for admission as States into the Union. No enactment of Congress could restrain the people of any of the sovereign States of the Union, old or new, North or South, slaveholding or nonslaveholding, from determining the character of their own domestic institutions as they may deem wise and proper. Any and all the States possess this right, and Congress can not deprive them of it. The people of Georgia might if they chose so alter their constitution as to abolish slavery within its limits, and the people of Vermont might so alter their constitution as to admit slavery within its limits. Both States would possess the right, though, as all know, it is not probable that either would exert it.

It is fortunate for the peace and harmony of the Union that this question is in its nature temporary and can only continue for the brief period which will intervene before California and New Mexico may be admitted as States into the Union. From the tide of population now flowing into them it is highly probable that this will soon occur.

Considering the several States and the citizens of the several States as equals and entitled to equal rights under the Constitution, if this were an original question it might well be insisted on that the principle of noninterference is the true doctrine and that Congress could not, in the absence of any express grant of power, interfere with their relative rights. Upon a great emergency, however, and under menacing dangers to the Union, the Missouri compromise line in respect to slavery was adopted. The same line was extended farther west in the acquisition of Texas. After an acquiescence of nearly thirty years in the principle of compromise recognized and established by these acts, and to avoid the danger to the Union which might follow if it were now disregarded, I have heretofore expressed the opinion that that line of compromise should be extended on the parallel of 36° 30' from the western boundary of Texas, where it now terminates, to the Pacific Ocean. This is the middle ground of compromise, upon which the different sections of the Union may meet, as they have heretofore met. If this be done, it is confidently believed a large majority of the people of every section of the country, however widely their abstract opinions on the subject of slavery may differ, would cheerfully and patriotically acquiesce in it, and peace and harmony would again fill our borders.

The restriction north of the line was only yielded to in the case of Missouri and Texas upon a principle of compromise, made necessary for the sake of preserving the harmony and possibly the existence of the Union. It was upon these considerations that at the close of your last session I gave my sanction to the principle of the Missouri compromise line by approving and signing the bill to establish "the Territorial government of Oregon." From a sincere desire to preserve the harmony of the Union, and in deference for the acts of my predecessors, I felt constrained to yield my acquiescence to the extent to which they had gone in compromising this delicate and dangerous question. But if Congress shall now reverse the decision by which the Missouri compromise was effected, and shall propose to extend the restriction over the whole territory, sorb as well as north of the parallel of 36° 30′, it will cease to be a compromise, and must be regarded as an original question.

If Congress, instead of observing the course of noninterference, leaving the adoption of their own domestic institutions to the people who may inhabit these territories, or if, instead of extending the Missouri compromise line to the Pacific, shall prefer to submit the legal and constitutional questions which may arise to the decision of the judicial tribunals, as was proposed in a bill which passed the Senate at your last session, an adjustment may be effected in this mode. If the whole subject be referred to the judiciary, all parts of the Union should cheerfully acquiesce in the final decision of the tribunal created by the Constitution for the settlement of all questions which may arise under the Constitution, treaties, and laws of the United States.

Congress is earnestly invoked, for the sake of the Union, its harmony, and our continued prosperity as a nation, to adjust at its present session this, the only dangerous question which lies in our path, if not in some one of the modes suggested, in some other which may be satisfactory.

In anticipation of the establishment of regular governments over the acquired territories, a joint commission of officers of the Army and Navy has been ordered to proceed to the coast of California and Oregon for the purpose of making reconnoissances and a report as to the proper sites for the erection of fortifications or other defensive works on land and of suitable situations for naval stations. The information which may be expected from a scientific and skillful examination of the whole face of the coast will be eminently useful to Congress when they come to consider the propriety of making appropriations for these great national objects. Proper defenses on land will be necessary for the security and protection of our possessions, and the establishment of navy-yards and a dock for the repair and construction of vessels will be important alike to our Navy and commercial marine. Without such establishments every vessel, whether of the Navy or of the merchant service, requiring repair must at great expense come round Cape Horn to one of our Atlantic yards for that purpose. With such establishments vessels, it is believed,

may be built or repaired as cheaply in California as upon the Atlantic coast. They would give employment to many of our enterprising shipbuilders and mechanics and greatly facilitate and enlarge our commerce in the Pacific.

As it is ascertained that mines of gold, silver, copper, and quicksilver exist in New Mexico and California, and that nearly all the lands where they are found belong to the United States, it is deemed important to the public interest that provision be made for a geological and mineralogical examination of these regions. Measures should be adopted to preserve the mineral lands, especially such as contain the precious metals, for the use of the United States, or, if brought into market, to separate them from the farming lands and dispose of them in such manner as to secure a large return of money to the Treasury and at the same time to lead to the development of their wealth by individual proprietors and purchasers. To do this it will be necessary to provide for an immediate survey and location of the lots. If Congress should deem it proper to dispose of the mineral lands, they should be sold in small quantities and at a fixed minimum price.

I recommend that surveyors-general's offices be authorized to be established in New Mexico and California and provision made for surveying and bringing the public lands into market at the earliest practicable period. In disposing of these lands, I recommend that the right of preemption be secured and liberal grants made to the early emigrants who have settled or may settle upon them.

It will be important to extend our revenue laws over these territories, and especially over California, at an early period. There is already a considerable commerce with California, and until ports of entry shall be established and collectors appointed no revenue can be received.

If these and other necessary and proper measures be adopted for the development of the wealth and resources of New Mexico and California and regular Territorial governments be established over them, such will probably be the rapid enlargement of our commerce and navigation and such the addition to the national wealth that the present generation may live to witness the controlling commercial and monetary power of the world transferred from London and other European emporiums to the city of New York.

The apprehensions which were entertained by some of our statesmen in the earlier periods of the Government that our system was incapable of operating with sufficient energy and success over largely extended territorial limits, and that if this were attempted it would fall to pieces by its own weakness, have been dissipated by our experience. By the division of power between t'e States and Federal Government the latter is found to operate with as much energy in the extremes as in the center. It is as efficient in the remotest of the thirty States which now compose the Union as it was in the thirteen States which formed our Constitution. Indeed, it may well be doubted whether if our present population had been confined within the limits of the original thirteen States the
