The gentleman from Massachusetts (Mr. Ames) has represented the proposed regulation as tending eventually to the ruin of the commerce, fisheries, and manufactures of that State. I do not believe (added he) such a consequence would result from a duty of eight cents on a gallon of molasses; if I did, I would be one of the last to advocate the measure; but to understand this circumstance more fully, let us proceed to an inquiry of the ground on which we stand. The State of Massachusetts imports a greater proportion of this article than any other in the Union; she will have therefore (say the opponents of the measure) to pay exclusively all the impost upon it. Let us examine this. Some part of the molasses is consumed in the substance, but all the remainder is distilled: this must either be consumed in the State, or exported from it; in the latter case, I would propose that all the rum shipped to foreign nations should draw back the duties it had paid as molasses. This would obviate all that was said relative to the competition between this State and other nations at a foreign market. As to what is exported, but consumed in some other parts of the United States, it is but proper that a duty should be paid, and although it may be advanced in the first instance by the people of Massachusetts, yet it will be ultimately paid by the consumers in other parts. What is consumed within the State itself, gentlemen surely do not mean to have excluded from a duty. If they consume more country rum than West India, they pay a less duty than those States which consume a greater proportion of the latter. As to what is used in its raw, unmanufactured state, it will be sufficient to observe, that as it is generally a substitute for sugar, the consumers will therefore avoid the tax on that article, and pay it on the other. In Pennsylvania they mostly use sugar; now, if the people there pay a tax on that article, it is but distributive justice that the people of Massachusetts pay one on the article they use for the same purpose. Mr. GOODHUE.--Fifteen cents, the sum laid on Jamaica spirits, is about one-third part of its value; now eight cents on molasses is considerably more: the former is an article of luxury, as was observed when it was under consideration, therefore that duty might not be improper; but the latter cannot be said to partake of that quality in the substance, and when manufactured into rum, it is no more a luxury than Jamaica spirits. I cannot see, therefore, why molasses ought to be taxed forty or fifty per cent. when the other pays but thirty-three. Surely the substance ought not to pay at this rate--then what good reason can be offered for the measure?
