ADYERTISER.—The American Minister has, it is said, submitted the following propositions to the Mexican Government :—l. The Rio del Norte to be the boundary between Texas and Mexico. 2. An indem.  nity of 5,000,000 dollars to be paid by Mexico. 3. Upper California to be ceded to the United States, as far down as the head of the Gulf; the river Gila, which empties itself into the Colorado of the west, to be the boundary. If this arrangement should be carried out, New California, embracing the splendid barhours of San Francisco, and Monte Rey on the Pa• cific coast, would become part and parcel of the American Union. A glance at the map will show, that the Americans would gain thereby an accession of territory, including Texas, equal to more than onethird of their present extent of conntry on the Western Continent. The River Gila, one of the affluents of the great river Colorado, runs from east to west, a little northwards of the head of the Gulf of California ; and if the Mexicans should cede the Rio Bravo del Norte, which no doubt they will do, on the side of the Gulf of Mexico, a: the boundary line of Texas ; and afterwards, which appears to us incredible, consent to run the line along that river, till it reaches the parallel of the River Gila, taking a westerly direction to the Colo. rado, and thence to the Pacific Ocean—we say, unhesitatingly, that modern history furnishes no example of such aggrandisement, brought about by the influence of giant overwhelming strength, against pitiable unresisting weakness. If the Mexican Congress should vote away this vast tract of country, it appears to us that a more suicidal act could not be perpetrated. To conceal from themselves for one moment the inevit_  able consequence, that Mexico Proper must speedily afterwards be absorbed in the vast Anglo-American Republic, would be the height of the blindest fatuity. But the grave consideration which forces itself upon our reluctant minds, and none can be better disposed than we are to view favourably the acts of the United States Government ; is it possible that France and England, especially the latter, will remain quiet spectators of such a vast acquisition of territory by the United States people P—without a murmur, without a serious resistance ! The aggressive spirit of the Ameri can policy, ♦eiled under the pretence of extending the sphere of their free institutions, now manifests itself in a manner which cannot but inspire anxiety, if not alarm, for the consequences. Whatever Mr. Polk may say, if France has already turned her attention to that quarter, and has lately, with great propriety, broached the doctrine of a "balance of power" in America, it is not the President's rain threat that " the United  States cannot in silence permit any European interference on the North American Continent; and should any such interference be attempted, will be ready to resist it at any and all hazards,"—it is not such mere declamatory protests that will deter France and England from exercising their equally undoubted privilege of acting as they may deem wise, and politic, and just ; nor from extending protection over the weak and the oppressed amongst the distant nations of the world, in the same way as at this moment they are achieving real permanent honour and glory by succouring and supporting a much-wronged State in the southern part of the American hemisphere. To suppose that England would yield the whole of Oregon, and allow, at the same time, the United States to seize upon Upper California—after having annexed Texas, by which the area of the American territory would be at one mighty struke of policy actually doubled in extent --is something so utterly beyond the bounds of imagination to conceive or for us to submit to, that we Cannot regard thesemonstrous pretensions and aggressive acts, without feeling the deepest anxiety for the result. The selfpraise and egotism, the affectation of humility and forbearance towards the neighbouring states, sanctimoniously seasoned with grave appeals to Heaven—which prevail throughout the whole of the speech of Mr. Folk —contrast but too painfully with the settled determined resolution, which, step by step, gains ground upon all the countries conterminous with the republic, compels concession by overwhelming force—extorts vast territories under the plea of compensation—and usurps the vast empire of the North American continent, under the hppocritical ple of advancing the happiness of mankind. Whilst Mexico stands indebted many millions to England, we shall never look on supinely, and see the territory which
