Instructs customs collectors, under section 61 of “An Act to regulate the collection of duties on imports and tonnage, passed 2 March 1799,” to estimate the value of the Norwegian dollar, now circulating “with a considerable depreciation,” in order to levy duties on goods and merchandise imported from Norway.
