Congress at its last session having made no provision for executing the fifteenth article of the treaty, by which the United States assume to make satisfaction for the "unliquidated claims" of our citizens against Mexico to "an amount not exceeding three and a quarter millions of dollars," the subject is again recommended to your favorable consideration.

The exchange of ratifications of the treaty with Mexico took place on the 30th of May, 1848. Within one year after that time the commissioner and surveyor which each Government stipulates to appoint are required to meet "at the port of San Diego and proceed to run and mark the said boundary in its whole course to the mouth of the Rio Bravo del Norte." It will be seen from this provision that the period within which a commissioner and surveyor of the respective Governments are to meet at San Diego will expire on the 30th of May, 1849. Congress at the close of its last session made an appropriation for "the expenses of running and marking the boundary line" between the two countries, but did not fix the amount of salary which should be paid to the commissioner and surveyor to be appointed on the part of the United States. It is desirable that the amount of compensation which they shall receive should be prescribed by law, and not left, as at present, to Executive discretion.

Measures were adopted at the earliest practicable period to organize the "Territorial government of Oregon," as authorized by the act of the 14th of August last. The governor and marshal of the Territory, accompanied by a small military escort, left the frontier of Missouri in September last, and took the southern route, by the way of Santa Fe and the river Gila, to California, with the intention of proceeding thence in one of our vessels of war to their destination. The governor was fully advised of the great importance of his early arrival in the country, and it is confidently believed he may reach Oregon in the latter part of the present month or early in the next. The other officers for the Territory have proceeded by sea.

In the month of May last I communicated information to Congress that an Indian war had broken out in Oregon, and recommended that authority be given to raise an adequate number of volunteers to proceed without delay to the assistance of our fellow-citizens in that Territory. The authority to raise such a force not having been granted by Congress, as soon as their services could be dispensed with in Mexico orders were issued to the regiment of mounted riflemen to proceed to Jefferson Barracks, in Missouri, and to prepare to march to Oregon as soon as the necessary provision could be made. Shortly before it was ready to march it was arrested by the provision of the act passed by Congress on the last day of the last session, which directed that all the noncommissioned officers, musicians, and privates of that regiment who had been in service in Mexico should, upon their application, be entitled to be discharged. The effect of this provision was to disband the rank and file of the regiment, and before their places could be filled by recruits the season had so far advanced that it was impracticable for it to proceed until the opening of the next spring.

In the month of October last the accompanying communication was received from the governor of the temporary government of Oregon, giving information of the continuance of the Indian disturbances and of the destitution and defenseless condition of the inhabitants. Orders were immediately transmitted to the commander of our squadron in the Pacific to dispatch to their assistance a part of the naval forces on that station, to furnish them with arms and ammunition, and to continue to give them such aid and protection as the Navy could afford until the Army could reach the country.

It is the policy of humanity, and one which has always been pursued by the United States, to cultivate the good will of the aboriginal tribes of this continent and to restrain them from making war and indulging in excesses by mild means rather than by force. That this could have been done with the tribes in Oregon had that Territory been brought under the government of our laws at an earlier period, and had other suitable measures been adopted by Congress, such as now exist in our intercourse with the other Indian tribes within our limits, can not be doubted. Indeed, the immediate and only cause of the existing hostility of the Indians of Oregon is represented to have been the long delay of the United States in making to them some trifling compensation, in such articles as they wanted, for the country now occupied by our emigrants, which the Indians claimed and over which they formerly roamed. This compensation had been promised to them by the temporary government established in Oregon, but its fulfillment had been postponed from time to time for nearly two years, whilst those who made it had been anxiously waiting for Congress to establish a Territorial government over the country. The Indians became at length distrustful of their good faith and sought redress by plunder and massacre, which finally led to the present difficulties. A few thousand dollars in suitable presents, as a compensation for the country which had been taken possession of by our citizens, would have satisfied the Indians and have prevented the war. A small amount properly distributed, it is confidently believed, would soon restore quiet. In this Indian war our fellow-citizens of Oregon have been compelled to take the field in their own defense, have performed valuable military services, and been subjected to expenses which have fallen heavily upon them. Justice demands that provision should be made by Congress to compensate them for their services and to refund to them the necessary expenses which they have incurred.

I repeat the recommendation heretofore made to Congress, that provision be made for the appointment of a suitable number of Indian agents to reside among the tribes of Oregon, and that a small sum be appropriated to enable these agents to cultivate friendly relations with them. If this be done, the presence of a small military force will be all that is necessary to keep them in check and preserve peace. I recommend that similar provisions be made as regards the tribes inhabiting northern Texas, New Mexico, California, and the extensive region lying between our settlements in Missouri and these possessions, as the most effective means of preserving peace upon our borders and within the recently acquired territories.

The Secretary of the Treasury will present in his annual report a highly satisfactory statement of the condition of the finances.

The imports for the fiscal year ending on the 30th of June last were of the value of $154,977,876, of which the amount exported was $21,128,010, leaving $133,849,866 in the country for domestic use. The value of the exports for the same period was $154,032,131, consisting of domestic productions amounting to $132,904,121 and $21,128,010 of foreign articles. The receipts into the Treasury for the same period, exclusive of loans, amounted to $35,436,750.59, of which there was derived from customs $31,757,070.96, from sales of public lands $3,328,642.56, and from miscellaneous and incidental sources $351,037.07.

It will be perceived that the revenue from customs for the last fiscal year exceeded by $757,070.96 the estimate of the Secretary of the Treasury in his last annual report, and that the aggregate receipts during the same period from customs, lands, and miscellaneous sources also exceeded the estimate by the sum of $536,750.59, indicating, however, a very near approach in the estimate to the actual result.
