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."

THE SENEGAL RIVER.

No doubt the prince's good intentions were greatly furthered by the convenience of this mode of trading. In short, gain made for itself its usual convenient channels to work in, and saved itself as much as it could the trouble of discovery, or of marauding. Ca da Mosto being, as was said before, the first modern European visiting Africa who himself gives an account of it, and being, moreover, an honest and intelligent man, possessing the rare combination of keen observation and clear narrative power, all that he writes is most valuable. He notices the differences, both as regards the people and the country, to be found on the opposite sides of the Senegal River. On the northern side he finds the men small, spare and tawny, the country arid and barren; on the southern side, the men "exceeding black, tail, corpulent and well made; the country green, and full of green trees." This latter is the country of Jalof, the same that Prince Henry first heard of in his intercourse with the Moors. Both men and women, Ca da Mosto says, wash themselves four or five times a day, being very cleanly as to their persons, but not so in eating, in which they observe no rule. They are full of words, and never have done talking; and are, for the most part, liars and cheats. Yet, on the other hand, they are very charitable; for they give a dinner or a night's lodging and a supper, to all strangers who come to their houses, without expecting any return.

KING BUDOMEL.

Leaving the country of the Jalofs, Ca da Mosto proceeded eight hundred miles further, as he says, (but he must, I think, have over-estimated his reckoning,) to the country of a negro potentate, called King Budomel. Here it appears that the religion, of the court at least, was Mohammedan, and Ca da Mosto records a conversation which he had with Budomel upon the subject. "The king asked him to give his opinion of their manner of worship, and also some account of his own religion. Hereupon Ca da Mosto told him, in presence of his doctors, that the religion of Mohammed was false, and the Romish the true one. This made the Arabs mad, and Budomel laugh; who, on this occasion, said that he looked upon the religion of the Europeans to be good, for that none but God could have given them so much riches and understanding. He added, however, that the Mohammedan law must be also good; and that he believed the negroes were more sure of salvation than the Christians; because God was a just Lord, and therefore, as He had given the latter Paradise in this world, it ought to be possessed in the world to come by the negroes, who had scarcely anything here, in comparison with the others."

THE RIVER GAMBRA

From Budomel's country the voyagers, sailing southwards, came to the river Gambra (now called Gambia), which they entered, but could not succeed in conciliating the natives, who attacked them with signal valour, and maintained the contest with almost unparalleled bravery, considering that the arms used by the Europeans were totally unknown to their opponents.

FURTHER DISCOVERIES.

During their stay in this river Ca da Mosto and his companions saw the constellation of the southern cross for the first time. Finding that the natives would have nothing to do with them,
