The negotiation of 1824 was productive of no result, and the convention of 1818 was left unchanged.

The negotiation of 1826, having also failed to effect an adjustment by compromise, resulted in the convention of August 6, 1827, by which it was agreed to continue in force for an indefinite period the provisions of the third article of the convention of the 20th of October, 1818; and it was further provided that—

It shall be competent, however, to either of the contracting parties, in case either should think fit, at any time after the 20th of October, 1828, on giving due notice of twelve months to the other contracting party, to annul and abrogate this convention; and it shall in such case be accordingly entirely annulled and abrogated after the expiration of the said term of notice.

In these attempts to adjust the controversy the parallel of the forty-ninth degree of north latitude had been offered by the United States to Great Britain, and in those of 1818 and 1826, with a further concession of the free navigation of the Columbia River south of that latitude. The parallel of the forty-ninth degree from the Rocky Mountains to its intersection with the northeasternmost branch of the Columbia, and thence down the channel of that river to the sea, had been offered by Great Britain, with an addition of a small detached territory north of the Columbia. Each of these propositions had been rejected by the parties respectively. In October, 1843, the envoy extraordinary and minister plenipotentiary of the United States in London was authorized to make a similar offer to those made in 1818 and 1826. Thus stood the question when the negotiation was shortly afterwards transferred to Washington, and on the 23d of August, 1844, was formally opened under the direction of my immediate predecessor. Like all the previous negotiations, it was based upon principles of "compromise," and the avowed purpose of the parties was "to treat of the respective claims of the two countries to the Oregon Territory with the view to establish a permanent boundary between them westward of the Rocky Mountains to the Pacific Ocean."

Accordingly, on the 26th of August, 1844, the British plenipotentiary offered to divide the Oregon Territory by the forty-ninth parallel of north latitude from the Rocky Mountains to the point of its intersection with the northeasternmost branch of the Columbia River, and thence down that river to the sea, leaving the free navigation of the river to be enjoyed in common by both parties, the country south of this line to belong to the United States and that north of it to Great Britain. At the same time he proposed in addition to yield to the United States a detached territory north of the Columbia extending along the Pacific and the Straits of Fuca from Bulfinchs Harbor, inclusive, to Hoods Canal, and to make free to the United States any port or ports south of latitude 49° which they might desire, either on the mainland or on Quadra and Vancouvers Island. With the exception of the free ports, this was the same offer which had been made by the British and rejected by the American Government in the negotiation of 1826. This proposition was properly rejected by the American plenipotentiary on the day it was submitted. This was the only proposition of compromise offered by the British plenipotentiary. The proposition on the part of Great Britain having been rejected, the British plenipotentiary requested that a proposal should be made by the United States for "an equitable adjustment of the question." When I came into office I found this to be the state of the negotiation. Though entertaining the settled conviction that the British pretensions of title could not be maintained to any portion of the Oregon Territory upon any principle of public law recognized by nations, yet in deference to what had been done by my predecessors, and especially in consideration that propositions of compromise had been thrice made by two preceding Administrations to adjust the question on the parallel of 49°, and in two of them yielding to Great Britain the free navigation of the Columbia, and that the pending negotiation had been commenced on the basis of compromise, I deemed it to be my duty not abruptly to break it off. In consideration, too, that under the conventions of 1818 and 1827 the citizens and subjects of the two powers held a joint occupancy of the country, I was induced to make another effort to settle this long-pending controversy in the spirit of moderation which had given birth to the renewed discussion. A proposition was accordingly made, which was rejected by the British plenipotentiary, who, without submitting any other proposition, suffered the negotiation on his part to drop, expressing his trust that the United States would offer what he saw fit to call "some further proposal for the settlement of the Oregon question more consistent with fairness and equity and with the reasonable expectations of the British Government." The proposition thus offered and rejected repeated the offer of the parallel of 49° of north latitude, which had been made by two preceding Administrations, but without proposing to surrender to Great Britain, as they had done, the free navigation of the Columbia River. The right of any foreign power to the free navigation of any of our rivers through the heart of our country was which I was unwilling to concede. I also embraced a provision to make free to Great Britain any port or ports on the cap of Quadra and Vancouvers Island south of this parallel. Had this been a new question, coming under discussion for the first time, this proposition would not have been made. The extraordinary and wholly inadmissible demands of the British Government and the rejection of the proposition made in deference alone to what had been done by my predecessors and the implied obligation which their acts seemed to impose afford satisfactory evidence that no compromise which the United States ought to accept can be effected. With this conviction the proposition of compromise which had been made and rejected was by my direction subsequently withdrawn and our title to the whole Oregon Territory asserted, and, as is believed, maintained by irrefragable facts and arguments.

The civilized world will see in these proceedings a spirit of liberal concession on the part of the United States, and this Government will be relieved from all responsibility which may follow the failure to settle the controversy.

All attempts at compromise having failed, it becomes the duty of Congress to consider what measures it may be proper to adopt for the security and protection of our citizens now inhabiting or who may hereafter inhabit Oregon, and for the maintenance of our just title to that Territory. In adopting measures for this purpose care should be taken that nothing be done to violate the stipulations of the convention of 1827, which is still in force. The faith of treaties, in their letter and spirit, has ever been, and, I trust, will ever be, scrupulously observed by the United States. Under that convention a year's notice is required to be given by either party to the other before the joint occupancy shall terminate and before either can rightfully assert or exercise exclusive jurisdiction over any portion of the territory. This notice it would, in my judgment, be proper to give, and I recommend that provision be made by law for giving it accordingly, and terminating in this manner the convention of the 6th of August, 1827.

It will become proper for Congress to determine what legislation they can in the meantime adopt without violating this convention. Beyond all question the protection of our laws and our jurisdiction, civil and criminal, ought to be immediately extended over our citizens in Oregon. They have had just cause to complain of our long neglect in this particular, and have in consequence been compelled for their own security and protection to establish a provisional government for themselves. Strong in their allegiance and ardent in their attachment to the United States, they have been thus cast upon their own resources. They are anxious that our laws should be extended over them, and I recommend that this be done by Congress with as little delay as possible in the full extent to which the British Parliament have proceeded in regard to British subjects in that Territory by their act of July 2, 1821, "for regulating the fur trade and establishing a criminal and civil jurisdiction within certain parts of North America." By this act Great Britain extended her laws and jurisdiction, civil and criminal, over her subjects engaged in the fur trade in that Territory. By it the courts of the Province of Upper Canada were empowered to take cognizance of causes civil and criminal. Justices of the peace and other judicial officers were authorized to be appointed in Oregon with power to execute all process issuing from the courts of that Province, and to "sit and hold courts of record for the trial of criminal offenses and misdemeanors" not made the subject of capital punishment, and also of civil cases where the cause of action shall not "exceed in value the amount or sum of £200."

Subsequent to the date of this act of Parliament a grant was made from the "British Crown" to the Hudsons Bay Company of the exclusive trade with the Indian tribes in the Oregon Territory, subject to a reservation that it shall not operate to the exclusion "of the subjects of any foreign states who, under or by force of any convention for the time being between us and such foreign states, respectively, may be entitled to and shall be engaged in the said trade." It is much to be regretted that while under this act British subjects have enjoyed the protection of British laws and British judicial tribunals throughout the whole of Oregon, American citizens in the same Territory have enjoyed no such protection from their Government. At the same time, the result illustrates the character of our people and their institutions. In spite of this neglect they have multiplied, and their number is rapidly increasing in that Territory. They have made no appeal to arms, but have peacefully fortified themselves in their new homes by the adoption of republican institutions for themselves, furnishing another example of the truth that self-government is inherent in the American breast and must prevail. It is due to them that they should be embraced and protected by our laws. It is deemed important that our laws regulating trade and intercourse with the Indian tribes east of the Rocky Mountains should be extended to such tribes as dwell beyond them. The increasing emigration to Oregon and the care and protection which is due from the Government to its citizens in that distant region make it our duty, as it is our interest, to cultivate amicable relations with the Indian tribes of that Territory. For this purpose I recommend that provision be made for establishing an Indian agency and such subagencies as may be deemed necessary beyond the Rocky Mountains.

For the protection of emigrants whilst on their way to Oregon against the attacks of the Indian tribes occupying the country through which they pass, I recommend that a suitable number of stockades and blockhouse forts be erected along the usual route between our frontier settlements on the Missouri and the Rocky Mountains, and that an adequate force of mounted riflemen be raised to guard and protect them on their journey. The immediate adoption of these recommendations by Congress will not violate the provisions of the existing treaty. It will be doing nothing more for American citizens than British laws have long since done for British subjects in the same territory.
