It is generally considered that Mr. Floyd has not resigned because of Major Anderson's patriotic course, but merely used it as a pretext to conceal the real cause. The whole country knows that his position, under the “trying circumstances,” has not been a very agreeable one, especially during the last two weeks. The alleged cause of his leaving Mr. Buchanan is, that the latter refuses to recall or order back to Fort Moultrie the gallant Anderson. Floyd asserts that he, some time ago, promised the South Carolina seceders to leave things in the harbor of Charleston undisturbed  --in statu quo ante bellum--and that the President gave the same promise. This agreement having been broken by Major Anderson, he insisted upon his returning to Fort Moultrie; and, because the President was unwilling to give that order, he sent in his resignation.--Philadelphia Press, Dec. 31.
The South Carolina troops took possession of the arsenal at Charleston. The arsenal contains many thousand arms and military stores. Military preparations are actively and zealously progressing.--Evening Post, Dec. 31.
