“Information or libel of seizure for importing into Boston, from the province of New Brunswick, certain coal, which was not truly goods or merchandise of the growth, produce, or manufacture of the said province, contrary to the act of 15 May 1820, ch. 122, § 3. At the trial, the principal inquiry was, whether the coal was the produce of the province of New Brunswick; and the evidence on both sides was so contradictory, that the question, on whom the burthen of proof rested, became the turning point of the cause.”
