The entering wedge in the Great split of the Republican party.
--The late scathing review by the Louisville Journal, of President Lincoln's message, is producing no little discussion in the West. The Louisville correspondent of the Cincinnati Commercial writes:‘ While the article alluded to has proved nothing, and simply misstated, or, at the most, exaggerated the somewhat cloaked idea of the President, it has produced much mischief and driven the first wedge in the split which is, without doubt, going to ensue as the natural result of the handling of the slavery question in the new phase in which it has presented itself — the clashing of State and Federal relations regarding slave property. The great split in the Union party, on which the rebels depended in the beginning, is not far distant.
