The Senate resumed as the unfinished business of yesterday, the bill in alteration of the several acts imposing duties on imports; the question being on the amendment proposed by Mr. PARRIS, to strike out that portion of the bill which abolished the drawback on the exportation of spirits distilled from molasses. The amendment was advocated by Messrs. Marks, Webster, Woodbury, and Parris, and opposed by Messrs. Smith, of Md., Van Buren, Branch, Tazewell, Benton, and Rowan.
