Mr. JACKSON (from Georgia) moved to lower the tonnage duty from thirty cents, as it stood in the report of the Committee on ships of nations in alliance, and to insert twenty cents, with a view of reducing the tonnage on the vessels of Powers not in alliance. In laying a higher duty on foreign tonnage than on our own, I presume, said he, the Legislature have three things in contemplation: 1st, The encouragement of American shipping; 2ndly, Raising a revenue; and 3rdly, The support of light-houses and beacons for the purposes of navigation. Now, for the first object, namely, the encouragement of American shipping, I judge twenty cents will be sufficient, the duty on our own being only six cents; but if twenty cents are laid in this case, I conclude that a higher rate will be imposed upon the vessels of nations not in alliance. As these form the principal part of the foreign navigation, the duty will be adequate to the end proposed. I take it, the idea of revenue from this source is not much relied upon by the House; and surely twenty cents is enough to answer all the purposes of erecting and supporting the necessary light-houses. On a calculation of what will be paid in Georgia, I find a sufficiency for these purposes; and I make no doubt but enough will be collected in every State from this duty. The tonnage employed in Georgia is about twenty thousand tons, fourteen thousand tons are foreign; the duty on this quantity will amount to £466 13s. 4d. Georgia currency. I do not take in the six cents upon American vessels, yet this sum appears to be as much as can possibly be wanted for the purpose of improving our navigation. I shall just mention to the House one observation more, to show that the produce of the Southern States cannot bear a high tonnage duty. The value of rice, tobacco, and indigo has fallen so much in foreign markets, that they are no longer worth the exportation. The merchants complain that they lose by those remittances; and they have now got into the practice of sending off specie; forty thousand dollars have been sent in one vessel. This is a daily practice, and we shall shortly have no specie left to pay our debts. The difficulty will be increased, as no money will remain to pay for the duties imposed on the articles imported. I hope the government will not insist upon our walking before we are able to creep, or compel us to make bricks without straw. These are my sentiments on the present question; if they have weight, the House will agree with me in reducing the duty; but if the House persist in continuing the high rates agreed to in committee, I shall content myself with having done my duty by warning them of the danger.
