That it must be considered rather in the light of a general pass, or licence, to the slave, privileging him to pursue his own business. The condition annexed, shews clearly that the master did not intend to renounce his authority, but to preserve it, in case the slave should fail in conforming to the conditions, he, the master, thought proper to im. pose.
