The Baltic arrived at Liverpool yesterday, with advices from New

York to the 22d November. The contents of some of the Southern journals show that the extreme party in the South look with apprehension to the future. The chief among them—the New Orleans Delta, said to be the organ of Mr. Jefferson Davis, Secretary at War—expresses a fear that it will be difficult if not impossible to bring Kansas in as a Slave State. The South will find "that non-extension of slavery was the middle ground on which the majority of Mr. Buchanan's supporters in the North agreed to stand." But Mr. Buchanan must remember that he " owes his election to the vote of the South" ; and he is told that "he will be a traitor, and insensible to every manly feeling of gratitude, if he forget it and disregard the obligations it implies." As there are doubts about Kansas, it is suggested that compensation should be found else- where.

" Let him live up to the letter and spirit of the Ostend letter ; let hint look to our interests in Cuba, which by right of geography and of political necessity should be ours ; let him fortify Walker in Nicaragua, and forestal Spanish and French designs upon Mexico ; let him place the great Tehuantepec route beyond the hazard of being lost to us by securing the grant of a strip of territory across that isthmus. The acquisition of Cuba, in defiance of England and France, would not split the Union—it would strengthen it. The regeneration of Central America, by Walker in alliance with the United States, would lead to the gradual emancipation of the West Indies from the infamous Free-Negroism established by the enemies of American Republicanism. The people from Maine to California are sick and tired of old issues. They want something new, bold, and expansive. They want a policy in keeping with steam, railroads, and telegraphs. They want new leaders, new homes, and new ideas. The new policy must come from the South."

It is now understood that Mr. Buchanan, in order to :secure the Cali- fornian vote, pledged himself at the last moment to the Pacific railroad scheme.
