account I received from Daman Jumma, who had thirty slaves at Kemmoo, all
of whom were made prisoners by Mansong. Again, when a freeman is taken
prisoner, his friends will sometimes ransom him by giving two slaves in
exchange; but when a slave is taken, he has no hopes of such redemption.
To these disadvantages, it is to be added, that the Slatees, who purchase
slaves in the interior countries, and carry them down to the Coast for

and was probably the origin of slavery; for when one nation had taken
from another a greater number of captives than could be exchanged on
equal terms, it is natural to suppose that the conquerors, finding it
