[Sidenote: Shels that cleaue to ships.] At their comming home the keeles of their shippes were marueilously ouergrowne with certaine shelles of two inches length and more, as thicke as they could stand, and of such bignesse that a man might put his thumbe in the mouthes of them. They certainely affirme that in these there groweth a certaine slimie substance, which at the length slipping out of the shell and falling in the sea, becommeth those foules which we call Barnacles. The like shelles haue bene seene in ships returning from Iseland, but these shels were not past halfe an inch in length. Of the other that came from Guinea, I sawe the Primerose lying in the docke, and in maner couered with the said shels, which in my iudgement should greatly hinder her sayling. Their ships were also in many places eaten with the wormes called Bromas or Bissas, whereof mention is made in the Decades. These creepe betweene the plankes, which they eate through in many places. [Sidenote: A secret.] Among other things that chanced to them in this voyage, this is worthy to be noted, that whereas they sailed thither in seuen weekes, they could returne in no lesse space then twentie weekes. The cause whereof they say to be this: That about the coast of Cabo Verde the winde is euer at the East, by reason whereof they were enforced to saile farre out of their course into the maine Ocean, to finde the winde at the West to bring them home. [Sidenote: The death of our men.] There died of our men at this last voyage about twentie and four, whereof many died at their returne into the clime of the colde regions, as betweene the Islands of Azores and England. [Sidenote: Fiue blacke Moores brought into England. Colde may be better abiden then heate.] They brought with them certaine black slaues, whereof some were tall and strong men, and could wel agree with our meates and drinkes. The colde and moyst aire doth somewhat offend them. Yet doubtlesse men that are borne in hot Regions may better abide colde, then men that are borne in colde Regions may abide heate, forasmuch as vehement heate resolueth the radicall moysture of mens bodies, as colde constraineth and preserueth the same. This is also to be considered as a secret worke of nature, that throughout all Africke, vnder the Æquinoctial line, and neere about the same on both sides, the regions are extreeme hote, and the people very blacke. Whereas contrarily such regions of the West Indies as are vnder the same line are very temperate, and the people neither blacke, nor with curlde and short wooll on their heads, as they of Afrike haue, but of the colour of an Oliue, with long and blacke heare on their heads: the cause of which variety is declared in diuers places in the Decades.
