When the war of 1812 was reached, a great but temporary change was made in the tariff laws by increasing the entire list of duties one hundred per cent .-- simply doubling the rate in every case.

Not content with this sweeping and wholesale increase of duty, the law provided an additional ten per cent.

upon all goods imported in foreign vessels, besides collecting an additional tonnage-tax of one dollar and a half per ton on the vessel.

Of course this was war-legislation, and the Act was to expire within one year after a treaty of peace should be concluded with Great Britain.

With the experience of recent days before him, the reader does not need to be reminded that, under the stimulus of this extraordinary rate of duties, manufactures rapidly developed throughout the country.
