A direct tax ought to fall as equally as possible every where; that on land and houses, with their improvements, which had been agreed to, would be laid by a valuation seldom repeated--perhaps, once in ten or fifteen years. The expense of its assessment and collection would be nearly equal throughout the United States; but, with respect to a tax on slaves, there would be required frequent enumerations--at least an annual enumeration. This would be attended with considerable expense, to be defrayed, not by the particular districts, for whose benefit this species of tax was introduced, but by the United States. There was another objection. A land tax was certain--it might, and undoubtedly would, be made a lien on the real estate on which it was laid. It would, be liable to little, if any, loss. Not so with a tax on slaves. Such a tax, he apprehended, would be uncertain, exposing the revenue to considerable defalcations. If a provision could not be made to place the loss on the districts where it happened, by retaxing them it would operate unequally. He imagined a retaxation for defalcation, if it could be made, would be considered as unjust, and create discontent among the individuals who were subjected to it; and if that could not be done, the deficiency must fall on the Union, and would produce uneasiness from its partial effects. He did not know how the detail would be arranged. He had been of the number who were desirous to see the collection-law, before they decided on the resolution before them, so as to have possessed the whole subject. At present, he saw so many difficulties from incorporating this species of tax into the plan, he could not assent to it. Mr. NICHOLAS said, he did not understand the objections of the gentleman from New Hampshire, (Mr. J. SMITH.) He did not see how he could produce an equal value in land in every part of the Union. The tax, he said, would be apportioned according to the number of persons, and not according to the number of acres in any State. If the gentleman from Connecticut (Mr. GOODRICH) would rely upon his information, he might be assured that an annual enumeration of slaves would not cost so much as an assessment of land made once in ten years. With respect to the tax being uncertain, he was totally mistaken. It was the most productive tax in the Southern States. If the tax was laid wholly upon land, it would be laid on a great part which would be unsaleable, and when a report came to be made of the collection, there would be found great deficiencies; but, with respect to slaves, there would be no failure, because they were a species of property which would always find a ready sale in the Southern market.
