As the port of Canton is the only one at which outside
barbarians are allowed to trade, on no account can they be
permitted to wander about to other places in the 'Middle
Kingdom.' The 'Son of Heaven,' however, whose compassion is as
boundless as the ocean, cannot deny to those who are in distress
from want of food, through adverse seas and currents, the
necessary means of continuing their voyage. When supplied they
must no longer loiter, but depart at once. Respect this.
