TRADE WITH THE ARABS.
From Ca da Mosto the reader at once learns the state of things with regard to the slave-trade. The Portuguese factory at Argnim was the headquarters of the trade. Thither came all kinds of merchandise; and gold and slaves were taken back in return. The "Arabs" of that district (Moors, the Portuguese would have called them) were the middle men in this affair. They took their Barbary horses to the negro country, and "there bartered with the great men for slaves," getting from ten to eighteen slaves for each horse. They also brought silks of Granada and Tunis, and silver, in exchange for which they received slaves and gold. These Arabs, or Moors, had a place of trade of their own, called Hoden, behind Cape Blanco. There the slaves were brought, "from whence," Ca da Mosto says, "they are sent to the mountains of Barka, and from thence to Sicily; part of them are also brought to Tunis and along the coast of Barbary, and the rest to Argin, and sold to the licensed Portuguese. Every year between seven and eight hundred slaves are sent from Argin to Portugal."
"Before this trade was settled," says Ca da Mosto, "the Portuguese used to seize upon the Moors themselves (as appears occasionally from the evidence that has before been referred to), and also the Azenegues, who live further towards the south; but now peace is restored to all, and the Infante suffers no further damage to be done to these people. He is in hopes, that by conversing with Christians, they may easily be brought over to the Romish faith, as they are not, as yet, well established in that of Mohammed, of which they know nothing but by hear-say."
