Noah Haynes Swayne,
Pacific Insurance Company v. Soule…
“ But an income tax can be apportioned as easily as any other direct tax; first, by determining the amount to be raised from incomes throughout the United States, and then by ascertaining the proportion to be paid by the people of each State. An income tax, in the matter of its apportionment, is not embarrassed by any other difficulties than those which grow out of apportionment, in the admitted cases of poll taxes and land taxes.It was clearly the object of the act, to compel parties to pay the legal percentage on their incomes, estimating them at their value in legal tender currency. ”
