April 13.—The rebel General Buford appeared before Columbus, Ky., and demanded its unconditional surrender.

—Last night the notorious bushwhacking gang of Shumate and Clark went to the house of an industrious, hard-working German farmer, named Kuntz, who lives some twenty-five to thirty miles from the mouth of Osage River, in Missouri, and demanded his money. He stoutly denied having any cash; but the fiends, not believing him, or perhaps knowing that he did have some money, deliberately took down a wood-saw which was hanging up in the cabin, and cut his left leg three times below and four times above the knee, with the saw. Loss of blood, pain, and agony made the poor fellow insensible, and he was unable to tell where the money was concealed. His mangled body was found to-day, life extinct. A boy who lived with him, succeeded in making his escape, terror-stricken, to give the alarm. After leaving Kuntz’s, the gang went to an adjoining American farmer, and not succeeding in their demands for money, they destroyed every thing in and about the place, took the man out, and literally cut his head off.—Missouri Democrat.
—The British schooner Maria Alfred, with an assorted cargo, intended for the rebels, was captured in latitude 28° 50′ N., longitude 95° 5′ W., by the National vessel Rachel Seaman.
