These negotiations occupied the late summer months.

At the end of September Mr.Gallatin was again at his post in Paris.
In June, 1818, Mr.Richard Rush, who owed his introduction into public life to Mr.Gallatin, was appointed minister to England, Adams returning to the United States to take the portfolio of State in President Monroe's cabinet.

Gallatin was joined to Rush, for the conduct of negotiations with Great Britain, rendered necessary by the approaching expiration of the commercial convention of July 3, 1815, which had been limited to four years.

The general field of disputed points was again entered.

It included the questions of impressment, the fisheries, the boundaries, and indemnity for slaves.
