Dec. 31. 1807
As the embargo amendatory act may not pass for some days, & I have received numerous letters stating gross evasions, the enclosed circular has been prepared wh. will go to-day if you approve it. You are fully authorised by the act to give such instructions as shall appear best adapted for carrying the act into effect. And that is the only substitute for penalties. The evasion to be immediately guarded against is that of laden registered vessels giving up their registers for coasting licenses, & sailing for a foreign port though clearing for a port of the United States.
My messenger will wait for your answer.
