The acts which the government of the United States may do, in conformity with the convention, embrace two objects: the measures applicable to the territory within their acknowledged limits which may facilitate and promote migration; and those which are necessary for the protection of their citizens residing in the Oregon territory.

It is a remarkable fact that, although the convention has now been in force twenty-seven years, Congress has actually done nothing with respect to either of those objects. Enterprising individuals have, without any aid or encouragement by Government, opened a wagon-road eighteen hundred miles in length, through an arid or mountainous region, and made settlements on or near the shores of the Pacific, without any guaranty for the possession of the land improved by their labors. Even the attempt to carry on an inland trade with the Indians of Oregon has been defeated, by the refusal to allow a drawback of the high duties imposed on the importation of foreign goods absolutely necessary for that commerce. Thus the fur trade has remained engrossed by the Hudson Bay Company; missionaries were, till very lately, almost the only citizens of the United States to be found in Oregon; the United States, during the whole of that period, have derived no other advantage from the convention than the reservation of their rights, and the express provision that these should in no way be affected by the continuance of the British factories in the territory. And, now that the tide of migration has turned in their favor, they are suddenly invited to assume a hostile position, to endure the calamities and to run the chances and consequences of war, in order to gain an object which natural and irresistible causes, if permitted to operate, cannot fail ultimately to attain.

The measures applicable to the territory within the acknowledged limits of the U. States have generally been recommended by the President. A very moderate appropriation will be sufficient to improve the most difficult portions of the road: and block-houses or other temporary works, erected in proper places and at convenient distances, and garrisoned by a portion of the intended additional force, will protect and facilitate the progress of the emigrants. However uninviting may be the vast extent of prairies, destitute of timber, which intervene between the western boundary of the State of Missouri and the country bordering on the Stony Mountains, it seems impossible that there should not be found some more favored spots where settlements may be formed. If these were selected for military posts, and donations of land were made to actual settlers in their vicinity, a series of villages, though probably not a continuity of settlements, would soon arise through the whole length of the road. The most important place, that which is most wanted, either as a place of rest for the emigrants, or for military purposes, is one in the immediate vicinity of the Stony Mountains. Reports speak favorably of the fertility of the soil in some of the valleys of the upper waters, within our limits—of Bear's river, of the Rio Colorado, and of some of the northern branches of the river Platte. There, also, the seat of justice might be placed of the new territory, whose courts should have superior jurisdiction over Oregon.

The measures which the United States have a right to carry into effect within the territory of Oregon must now be considered.

The only positive condition of the convention is, that the territory in question shall, together with its harbors, bays, and creeks, and the navigation of all rivers within the same, be free and open to vessels, citizens, and subjects of the two Powers.

For the construction put on this article by Great Britain, it is necessary to recur again to the statement of her claim, as given by herself, and to her own acts subsequent to the convention.

The acts of England, subsequent to the convention of 1818, are to be found in the various charters of the Hudson Bay Company (observing that some of their most important provisions, though of a much earlier date, stand unrepealed), and in the act of Parliament of the year 1821, which confirms and extends a prior one of the year 1803. It must also be recollected that, by grants or acts subsequent to the convention, the ancient Hudson Bay Company and the Northwest Company of Montreal have been united together, preserving the name of Hudson Bay Company.

This Company was and remains a body corporate and politic, with provisions for the election of a Governor and other officers, who direct its business; and amongst other powers, the Company is empowered to build fortifications for the defence of its possessions, as well as to make war or peace with all nations or people, not Christian, inhabiting their territories, which now embrace the entire Oregon. By the act of Parliament of 1821, the jurisdiction of the courts of Upper Canada is extended, in all civil and criminal cases, to the Oregon territory; provision is made for the appointment of justices of the peace within the said territory, with a limited jurisdiction, and power to act as Commissioners in certain cases, and to convey offenders to Upper Canada.

It must also be observed that, although the Company is forbidden to claim any exclusive trade with the Indians, to the prejudice or exclusion of any citizen of the United States who may be engaged in the same trade, yet the jurisdiction above mentioned is, by the letter of the act, extended to any persons whatsoever residing or being within the said territory. The British Plenipotentiaries did, however, explicitly declare, in the course of the negotiations of 1826-1827, that the act had no other object but the maintenance of order amongst British subjects, and had never been intended to apply to citizens of the United States.

It is perfectly clear that, since it has been fully admitted that the United States possess the same rights over the territory as Great Britain, they are fully authorized, under the convention, to enjoy all the rights which Great Britain claims for herself, and to exercise that jurisdiction which she has assumed as being consistent with the convention.

The citizens of the United States have, therefore, at this time a full and acknowledged right to navigate the waters of the Oregon territory, to settle in and over any part of it, and freely to trade with the inhabitants and occupiers of the same. And the Government of the United States is likewise fully authorized to incorporate any company or association of men for the purpose of trading or of occupying and settling the country; to extend the jurisdiction of the courts of any of its territories lying within its acknowledged limits, in all civil and criminal cases, to the territory aforesaid; to appoint within the same justices of the peace and such other officers as may be necessary for carrying the jurisdiction into effect; and also to make war and peace with the Indian inhabitants of the territory, including the incidental power to appoint agents for that purpose.

On the other hand, it seems to be understood that, so long as the convention remains in force, neither Government shall lay duties in the Territory on tonnage, merchandise, or commerce; nor exercise exclusive jurisdiction over any portion of it; and that the citizens and subjects of the two Powers, residing in or removing to the territory, shall be amenable only to the jurisdiction of their own country respectively.

It has been contended by the British Government that the establishment of any military post, or the introduction of any regular force under a national flag, by either Power, would be an act of exclusive sovereignty, which could not be permitted to either whilst the sovereignty remained in abeyance. Under existing circumstances, it is believed that such an act would be highly dangerous, and prove unfavorable to the United States.

But the establishment by the United States of a Territorial Government over Oregon is also objected to on the same principle. The want of such government appears to be the only serious inconvenience attending a continuance of the convention, and requires special consideration.

The United States have the same right as Great Britain, and are equally bound, to protect their citizens residing in the Oregon territory, in the exercise of all the rights secured to them by the convention. It has been fully admitted that these rights embrace the right to settle in and over any part of the territory, and that they are to be, in all cases whatever, amenable only to the jurisdiction of their own country. The subjects of Great Britain, who are not in the employ of the Hudson Bay Company, are forbidden to trade with the natives; and the company does in fact control and govern all the British subjects residing in the territory. This gives a strong guaranty against the violation, by rash individuals, of the rights of the citizens of the United States. Should any of them, however, be disturbed in the exercise of their legitimate rights, and the company should be unable or unwilling to relieve and indemnify them, the United States would be justly entitled to appeal to the British Government for the redress of a violation of rights secured by the convention; for the British Government has preserved a control over the Hudson Bay Company, and does in fact, through it, govern the British subjects who reside in the territory.

The United States are placed, in that respect, in a very different situation. It is not believed that the General Government is authorized to incorporate, as a political body, a commercial company, with such powers as would give it an efficient control over the private citizens residing in the territory. Such delegation of powers, either by any of the States or by Congress, is wholly inconsistent with our institutions. The United States may indeed give to their citizens in Oregon a regular and complete judiciary system; and they may also extend to them, as the British Government has done on its part, the laws of an adjacent territory. But an executive local power is wanted in this case, as it is everywhere else, under any form of government whatever, to cause the laws to be executed, and to have that general control which is now exercised, through the Hudson Bay Company, by the British Government. There are, besides, various acts of a public though local nature, such as opening roads, making bridges, erecting block-houses for protection against the natives, providing for the destitute, &c., all which are performed by the Hudson Bay Company, and cannot be accomplished by insulated individuals, bound by no legal association or government.

Whether any measures may be devised, other than a territorial government, that will be sufficient for the purpose intended; whether all the American citizens residing in Oregon might not be incorporated and made a body politic, with powers equivalent to those vested in the Hudson Bay Company, and with the reservation by the General Government of a check or control analogous to that reserved by the Government of Great Britain, are questions worthy of serious consideration. But Great Britain has the same interest as the United States to prevent collision during the continuance of the convention; and it is believed that, if negotiations should be renewed, with an equal and sincere desire on both sides to preserve friendly relations, there would be no difficulty at this time in coming to an understanding on the subject. It would seem sufficient that this should be accompanied with provisions, preventing the possibility of the powers exercised by the United States being ever applied to British subjects, and with an explicit declaration that these powers should never be construed as an admission by Great Britain of any claim of the United States to exclusive sovereignty.

There is another important subject which has not, it is believed, ever been discussed by the two Powers. This is the claim to the ownership of the places settled and improved under the convention. It seems to me that, on the principles of both natural and international law, these rights, to a defined extent, should be respected by each Power respectively, whose sovereignty over the portion of the territory in which such improved settlements may be situated will ultimately be recognized. It appears also that the United States may, in conformity with the convention, and without affecting in any shape the claims advanced by Great Britain, pass a law declaring that they abandon or grant without warranty, to such of their citizens as shall have made actual and bon fide settlements in any part of Oregon, under the convention, all the rights of and claims to the ownership of the soil, on which such settlements shall have been made, which the United States may now or hereafter claim or acquire: limiting and defining the extent of the grant in the same manner as would be done if such grant was absolute; and promising that the title should be confirmed, in case and whenever the sovereignty of the United States was recognized or asserted and maintained.

The prolongation, in 1827, of the convention of 1818, was evidently intended as a temporary measure, since it was made revocable at the will of either party. The plenipotentiaries of the two Powers had been unable to agree on the terms of a definitive arrangement, or even in defining with precision the conditions on which the convention of 1818 might be continued for a determinate period. It will be seen, by reference to the protocols and correspondence, that, although it was generally admitted that neither party ought during such continuance to exercise any exclusive sovereignty over the territory, the American Plenipotentiary declined to agree to any convention containing an express provision to that effect, or accompanied by the insertion in the protocol of a declaration for the same purpose by the British Plenipotentiaries. The reason was not only because an exclusive right over Astoria and its dependencies was claimed by the United States, but principally because it was anticipated that, in order to have in fact an authority equal to that exercised by the Hudson Bay Company, it would become necessary for the United States to perform acts which the British Government might contend to be forbidden by such express provision or declaration. The consequence was, that the convention recognizes some certain rights, and imposes no positive restrictions but only such, as may be supposed to be implied in the clause which declares, that nothing contained in it should be construed to impair or affect the claims of either party. The probability that it might become necessary for the United States to establish a territory or some sort of government over their own citizens was explicitly avowed; the deficiencies of the renewed convention of 1827, and the inconveniences which might ensue, were fully understood; and the continuance of that of 1818, made revokable at will, was agreed on, with the hope that the two Powers would embrace an early opportunity, if not to make a definitive arrangement, at least to substitute for the convention another, defining with precision the acts which both parties should be allowed or forbidden to perform so long as the sovereignty remained in abeyance.

The inconveniences alluded to have been fairly stated in this paper, and some of the means by which they may be avoided have been suggested. It is not, therefore, on account of the intrinsic value of the convention that its abrogation is objectionable and dangerous. It is because nothing is substituted in its place; it is because, if the two Powers are not yet prepared to make a definitive agreement, it becomes the duty of both Governments, instead of breaking the only barrier which still preserves peace, to substitute for the existing convention one adapted to the present state of things, and which shall prevent collisions until the question of sovereignty shall have been settled. The inconveniences which were only anticipated have become tangible, from the time when American citizens, whom the United States are bound to protect, began to make settlements in the territory of Oregon. The sudden transition, from an agreement however defective to a promiscuous occupancy, without any provisions whatever that may prevent collisions, is highly dangerous. When this is accompanied by an avowed determination on the part of the United States to assume that exclusive sovereignty which Great Britain has positively declared she would resist, War becomes inevitable.
