"The present political relations of this continent cannot long continue, and it becomes this nation to be prepared for the change which awaits it. If the subjects of the British crown shall consent to be ruled through all time by a distant cabinet, Mexico cannot long exist under the misrule of marauders and their pronunciamentos, and this was as clearly apparent before as since the existence of the war. If then, just acquisition is the true policy of this Government, as it clearly is, it should be pursued by a steady and unyielding purpose, and characterized by the sternest principles of national justice. It should not rashly anticipate the great results which are in progress, nor thrust aside the fruits when they are produced and presented. The national existence of Mexico is in her own keeping, but is more endangered at this time by her own imbecility and stubbornness--her national ignorance and brutality--than from the war we are prosecuting and all its consequences. She has been hastening to ruin for years upon the flood-tide of profligacy and corruption; and if she is now rescued, and her downfall arrested and postponed for a season, it may justly be attributed to the salutary influences of the chastisement she has received." These general ideas upon the subject of territorial acquisition will indicate Mr. Dickinson's views upon the Cuban and Mexican questions of to-day. JOHN BELL. John Bell is a man of the old school in politics, an ancient southern Whig, who has preserved his whiggery intact, and has not been swallowed up in the Democratic party, but has rather sympathized to a great extent with the party in the North which has taken the place of the old Whig organization--the Republican party. Coming from a slave State, and himself a slaveholder, of course Mr. Bell does not belong to the Republican organization. He could not well do so without occupying an anti-slavery attitude in Tennessee. But he has acted in concert with the Republicans on most issues in Congress, and upon many of the issues which slavery has raised, he has taken sides with the North. In this manner he has gained the respect of his colleagues who go further than he does in opposition to slavery.
