Columbus Evacuated

Tliere is no longer a doubt tliat , umbus, the rebel Gibraltar, the j nablo barrier of the Mississippi, the outpost relied upon to protect New Orleans, has beca evacuated. The guns havo been removed, the fortifications blown up, and the town rcduced to ashes. We presume the work of evacuation has been going on ever since the fall of Donelson, and that everything has been removed that was possible; With all the boasted strength of its position and fortifications, the rebel officers could not bravo the mortar and gun-boats in front and a victorious army in the rear, and so have escaped whüe escapo was possible. Though Columbus is evacuated it is not yot certain where the Columbus reb els have fled to, and the reports are various and contradietory. One report says that guns and m-en have been removed to Island Xo. 10, about 45 miles bclow Columbus, that this Island is to be made a new Gibraltar, and that below it the Yankee iuvaders will never be permitted to go. We dou't believo, however, that any great number of men or guns will be trusted on an Island. They were caught in such a scrape at Roanoke, and couldn't run. Another report says that the Columbus forces have fallen down the river to Fort Randolph, located at lïandolph, Tipton County, Tenn. This town is 173 miles from Nashville, at tbe mouth of tbe Big Hatchie, at the head of the 'sec ond Chickasaw Bluff, and 67 miles above Memphis. It is considerable of a cotton port, but has no railroad communieation interior. Still another report says that the stand will be made at Memphis. Wo shall see. - Official advices say that quarters and barracks were burned, but that the town was spared ; also that the fortifications wore not blown up.
