. 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 (JA
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).
