But before wee arive at our next Harbour, St _Jago_, one of the _Iles_ of Cape Verd, and now revolted from the King of Spayne, to the Portugall; Let me tell you, one little observation I made of the Ships way; which in slacke windes, and darke nights, wee saw nothing under water, but darkenes; but in stiffe windes, and strong gayles, wee saw perfectly the keele of the Ship; and fishes playing underneath, as lighted by a torch, and yet the nights of equall darkenes. Which put me in mind of a poynt of Philosophy I had heard discourst of, among the Learned; That in the Ayer, Rough hard bodies, meeting with one another, by violent stroakes, Rarifie the Ayer, so as to make fire. So here, the ship being of a hard substance, and in a violent motion, meeting with the strong resistance of the waves: (who though they bee not hard, yet they are rough, by reason of their saltnes,) doe cause a light, though no fire, and I may guesse, that that light would bee fire, were it not quencht by the sea, in the instant it is made; which in his owne Element, hath the greater power and predominancie. But before wee came to St _Jago_, wee were to have visited a small Iland called _Soll_; by the intreatie of a Portugall wee carried with us, whose name was _Bernardo Mendes de Sousa_; who pretended, to have a great part of the Iland (if not the whole) to bee his owne; but for that, it lay somewhat out of our waye, and wee could not recover it, by reason the winde was Crosse; and partly for that wee were informed by some of the Saylers, who told us it was uninhabited by any, but Goats, Dogs, and the like; and wee guest, hee would (out of a vaine glorie) shew us something that he Call’d his. But the Master, who well knew the Condition of the place, would not lose so much tyme to no purpose. Which gave some discontentment to the Portugall, which hee exprest in his Countenance, by a sullen dogged looke, till wee came to St _Jago_. But that was but a whetstone, to sharpen a worse humour hee was big with; for though our Merchants redeem’d him out of prison in _London_, intending him a Mayne director in the whole voyage; whose Credulous eares hee highly abused, by telling them, That the _Padre Vagado_ (Chiefe Governour of St _Jago_) was his brother, and that by the power hee had with him, to lay all trade open, for Negroes, Horses, and Cattle, which were there Contrabanded goods; By which perswasion, they gave him the power and Command of the ship and goods. But hee intended nothing lesse then the performance of that trust, but instead of it, meant to make prey of both, and of our Liberties, and probably lives to boote, if wee had not bin verie wary of him.
