The same year, the Constitutional Convention, in session at
Philadelphia, inserted a like fugitive slave clause in the Federal
Constitution.
On the 12th of February, 1793, Congress passed an act providing the
method for carrying into effect the section of the constitution
relating to fugitives from justice and fugitive slaves. Both subjects
are treated and provided for in the same act. It passed both houses of
Congress by practically unanimous votes—Washington approving the bill
with his signature.
