Supplementary Treaty Signed By Their ExcellenciesSir Henry Pottinger and Ki Ying Respectively… (1843)
“ The Chinese Superintendent of Customs at each port will adopt the means that he may judge most proper to prevent the revenue suffering by fraud or smuggling. Whenever the pilot shall have brought any British merchantman into port, the Superintendent of Customs will depute one or two trusty Customhouse officers, whose duty it will be to watch against frauds on the revenue. These will either live in a boat of their own, or stay on board the English ship, as may best suit their convenience. ”
