. With the proceeds from the sale of whale oil in France, Thomas Boylston purchased
raw sugar to ship to Boston for refining and exportation to Europe or Russia (
to James Bowdoin, 24 March, MHi
: Winthrop Papers). Boylston's effort was part of a larger plan on his part to establish
a regular trade in American whale oil, French goods, and West Indian sugar. For the
specifics of his plan see Jefferson, Papers
, 9:29–31. His negotiations resulted in the lowering of duties on all whale oil imported
by Americans into France on either French or U.S. vessels (same, 9:88).
