undiscovered was Diego Cam, in 1484.  After passing Cape St. Catherine, he encountered a very strong current setting direct from the land, which was still at a considerable distance; on tasting the water, however, it was found to be fresh, from which the conjecture was drawn, that he was at the mouth of some great river, which ultimately turned out to be the fact.  This river has since been celebrated under the name of the Congo, or the Zaire, lying in latitude 8 deg. south, and longitude 13 deg. east.  On reaching the southern bank of the river, Diego planted his first pillar, after which he ascended its borders, and opened a communication with the natives by means of signs.  His first inquiry was respecting the residence of their sovereign, and, on receiving the information, that he resided at the distance of several days journey inland, he determined to send a number of his men with presents for the prince, the natives undertaking to be the guides, and pledging themselves, within a stipulated period, to conduct them back again.  As the natives meantime passed and repassed on the most intimate footing, Diego took the advantage of a moment, when several of the principal persons were on board his ship, weighed anchor and put to themselves as good and bona fide Christians, as any of the revered men, who had been sent out to instruct them.  The early missionaries, however, committed the same fault, which has distinguished the labours of those of later periods, for they immediately began attack one of the most venerated institutions of the realm of Congo which was polygamy; and to the aged monarch the privation of his wives appeared so intolerable, that he renounced the Christian faith, and relapsed into all the impurities of paganism and polygamy.  The heir apparent, however, saw nothing so very dreadful in the sacrifice of his wives, and braving the displeasure of his father, remained attached to the Portuguese.  The holy fathers managed their business on this occasion with that skill, for which the cowled tribe have ever been distinguished, and by the aid of the Apostle St. James, and a numerous cavalry of angels, the old king died, and Alphonso, the zealous convert, became entitled to reign.  His brother, however, Panso Aquitimo, supported by the nobles and almost the whole nation, raised the standard of revolt, in support of polygamy and paganism.  A civil war ensued, which is generally the attendant upon the proselytism of a people, and Alphonso had only a handful of Portuguese to oppose to the almost innumerable host of his countrymen; but the holy fathers again applied to their auxiliaries, and in consequence of apparitions in the clouds, at one time of St. James, and another of the Virgin Mary, Alphonso always came off victorious, and as he thereby became firmly seated on the throne, the missionaries secured for themselves a safe and comfortable establishment at Congo.  The following account of the conduct of these missionaries, as it is given in the Edinburgh Cabinet Library, cannot fail to afford a considerable degree of entertainment, at the same time, it is much to be deplored, that men engaged in so sacred a cause, “could play such fantastic tricks before high heaven,” and disgrace the doctrine, which they meant to teach.
