By these practices the first discoverers alienated the natives from them; and whenever a ship appeared, every one that could fly betook himself to the mountains and the woods, so that nothing was to be got more than they could steal:  they sometimes surprised a few fishers, and made them slaves, and did what they could to offend the negroes, and enrich themselves.  This practice of robbery continued till some of the negroes, who had been enslaved, learned the language of Portugal, so as to be able to interpret for their countrymen, and one John Fernandez applied himself to the negro tongue.

From this time began something like a regular traffick, such as can subsist between nations where all the power is on one side; and a factory was settled in the isle of Arguin, under the protection of a fort.  The profit of this new trade was assigned, for a certain term, to Ferdinando Gomez; which seems to be the common method of establishing a trade, that is yet too small to engage the care of a nation, and can only be enlarged by that attention which is bestowed by private men upon private advantage.  Gomez continued the discoveries to cape Catharine, two degrees and a half beyond the line.

In the latter part of the reign of Alphonso the fifth, the ardour of discovery was somewhat intermitted, and all commercial enterprises were interrupted by the wars in which he was engaged with various success.  But John the second, who succeeded, being fully convinced both of the honour and advantage of extending his dominions in countries hitherto unknown, prosecuted the designs of prince Henry with the utmost vigour, and in a short time added to his other titles, that of king of Guinea and of the coast of Africa.

In 1463, in the third year of the reign of John the second, died prince Henry, the first encourager of remote navigation, by whose incitement, patronage and example, distant nations have been made acquainted with each other, unknown countries have been brought into general view, and the power of Europe has been extended to the remotest parts of the world.  What mankind has lost and gained by the genius and designs of this prince, it would be long to compare, and very difficult to estimate.  Much knowledge has been acquired, and much cruelty been committed; the belief of religion has been very little propagated, and its laws have been outrageously and enormously violated.  The Europeans have scarcely visited any coast, but to gratify avarice, and extend corruption; to arrogate dominion without right, and practise cruelty without incentive.  Happy had it, then, been for the oppressed, if the designs of Henry had slept in his bosom, and surely more happy for the oppressors.  But there is reason to hope that out of so much evil, good may sometimes be produced; and that the light of the gospel will at last illuminate the sands of Africa, and the deserts of America, though its progress cannot but be slow, when it is so much obstructed by the lives of Christians.
