1To Thomas Jefferson from Tench Coxe, 20 February 1793 (Jefferson Papers)
...it is agreed no trial in holland has yet been made. It is admitted by Mr. Heineken that the prohibition of flour, bread and pealed Barley, tho our produce, could not be avoided by the cover of the West India Company—nor could the prohibitory duties of Beef nor the great duties on butter be so avoided.
