But it is necessary now to consider what the principles of the compromise act really are.

The first principle is, that there should be a fixed rate of ad valorem duty, and discriminations below it.

Second, that the excess of duty beyond twenty per centum should, by a gradual process, commencing on the thirty-first of December, 1833, be reduced, so that by the thirtieth of June, 1842, it should be brought down to twenty per centum.

Third, that after that day, such duties should be laid for the purpose of raising such revenue as might be necessary for an economical administration of the government; consequently excluding all resort to internal taxation, or to the proceeds of the public lands. For, contemporaneously with the pendency of the compromise act, a bill was pending for the distribution of those proceeds.

Fourth, that after the thirtieth of June, 1842, all duties should be paid in ready money, to the exclusion of all credits.

Fifth, that, after the same day, the assessment of the value of all imports should be made at home and not abroad.

Sixth, that after the same day, a list of articles specified and enumerated in the act, should be admitted free of duty, for the benefit of the manufacturing interest.

These are the principles, and all the principles of the compromise act. An impression has been taken up most erroneously, that the rate of duty was never to exceed twenty per centum. There is no such limitation in the act. I admit that, at the time of the passage of the act, a hope was entertained that a rate of duty not exceeding twenty per centum would supply an adequate revenue to an economical administration of the government. Then we were threatened with that overflow of revenue with which the treasury was subsequently inundated; and the difficulty was to find articles which should be liberated from duty and thrown into the free class. Hence, wines, silks, and other luxuries, were rendered free. But the act, and no part of the act, when fairly interpreted, limits congress to the iron rule of adhering for ever, and under all circumstances, to a fixed and unalterable rate of twenty per centum duty. The first section is in the following words:

“Be it enacted, and so forth, that, from and after the thirty-first day of December, one thousand eight hundred and thirty-three, in all cases where duties imposed on foreign imports by the act of the fourteenth day of July, one thousand eight hundred and thirty-two, entitled ‘an act to alter and amend the several acts imposing duties on imports,’ or by any other act, shall exceed twenty per centum on the value thereof, one tenth part of such excess shall be deducted; from and after the thirty-first day of December, one thousand eight hundred and thirty-five, another tenth part thereof shall be deducted; from and after the thirty-first day of December, one thousand eight hundred and thirty-seven, another tenth part thereof shall be deducted; from and after the thirty-first day of December, one thousand eight hundred and thirty-nine, another tenth part thereof shall be deducted; and from and after the thirty-first day of December, one thousand eight hundred and forty-one, one half of the residue of such excess shall be deducted; and from and after the thirtieth day of June, one thousand eight hundred and forty-two, the other half thereof shall be deducted.”

The provision of that section is nothing more nor less than that the existing duties should be, by the thirtieth of June, 1842, brought down to twenty per centum. What then? Were they always to remain at that rate? The section does not so declare. Not only is this not expected, and was not so understood, but directly the reverse is asserted, and was so understood, if the exigencies of the treasury required a higher rate to provide the revenue necessary to an economical administration of the government. The third section, which embodies most of the great principles of the act, is in these words:
