Mr. MADISON.--I do not consider it at this moment necessary to fill up the blanks, nor had I it in contemplation at the time I offered the propositions. I supposed that most of the gentlemen would wish time to think upon the principles generally, and upon the articles particularly; while others, who, from their situation and advantages in life, are more conversant on this subject, may be induced to turn their particular attention to a subject they are well able to do justice to, and to assist the committee with their knowledge and information; unless such gentlemen are now prepared and disposed to proceed in filling up the blanks, I shall second the motion for the committee's rising. THURSDAY, April 9. EGBERT BENSON, from New York, and ISAAC COLES, from Virginia, appeared and took their seats. _Duties on Imports._ The House again resolved itself into a Committee of the Whole on the state of the Union, Mr. PAGE in the chair. Mr. LAWRENCE.--The subject of the proposition laid before the committee by the honorable gentleman from Virginia, (Mr. MADISON,) will now, I presume, Mr. Chairman, recur for our deliberation. I imagine it to be of considerable importance, not only to the United States, but to every individual of the Union. The object of the revenue alone would place it in this situation, and in this light I mean now to consider it. If I am not mistaken, the honorable mover of the plan viewed it as a temporary system, particularly calculated to embrace the spring importations; therefore, in order to discover whether the mode laid before you is well calculated to answer this end, it will be proper to consider its operation. The plan consists of certain distinct propositions; one part is intended to lay a specific sum on enumerated articles, the other a certain per cent. _ad valorem_: perhaps simplifying the system may be productive of happy consequences, and it strikes me that confusion and perplexity will be best avoided by such a measure; hence, it may be proper to lay a duty at a certain rate per cent. on the value of all articles, without attempting an enumeration of any; because, if we attempt to specify every article, it will expose us to a question which must require more time than can be spared, to obtain the object that appears to be in the view of the committee. A question, I say, sir, will arise, whether the enumeration embraces every article that will bear a duty, and whether the duty to be affixed is the proper sum the article is able to bear. On this head, sir, I believe that the committee have not materials sufficient to form even the basis of the system, beside being wholly incompetent to determine the rate most advantageous to the article of revenue, and most agreeable to the interest and convenience of our constituents. Knowledge on these points can only be obtained by experience; but hitherto we have had none, at least of a general nature. The partial regulations made by the States, throw but little light on
