This Ilande of _Cubagua_ where this manner of fysching is exercised, is in the Northe coaste, and is no bygger then the Iland of Zelande. Oftentymes the sea encreaseth greatly, and muche more then the fyshers for pearles wold, bycause where as the place is very depe, a man can not naturally rest at the bottome by reason of the aboundaunce of aery substannce whiche is in hym, as I have oftentymes proved. For althoughe he may by vyolence and force descende to the bottome, yet are his feete lyfted up ageyne so that he can continue no tyme there. And therefore where the sea is verye deepe, these Indian fyshers use to tye two great stoones aboute them with a corde, on every side one, by the weyght whereof they descend to the bottome and remayne there untyl them lysteth to ryse ageine: At which tyme they unlose the stones, and ryse uppe at their pleasure. But this their aptenesse and agilitie in swimming, is not the thynge that causeth men moste to marvaile: But rather to consyder how many of them can stande in the bottome of the water for the space of one hole houre and summe more or lesse, accordynge as one is more apte hereunto then an other. An other thynge there is whiche seemeth to me very straunge. And this is, that where as I have oftentymes demaunded of summe of these lordes of the Indians, if the place where they accustomed to fysche for pearles beynge but lyttle and narrowe wyll not in shorte tyme bee utterly without oysters if they consume them so faste, they al answered me, that although they be consumed in one parte, yet if they go a fyschynge in an other parte or on another coaste of the Ilande, or at an other contrary wynd, and continue fysshing there also untyll the oysters be lykewyse consumed, and then returne ageyne to the fyrste place, or any other place where they fysshed before and emptied the same in lyke maner, they find them ageine as ful of oysters as though they had never bin fysshed. Wherby we may judge that these oysters eyther remove from one place to an other as do other fysshes, or elles that they are engendered and encrease in certeyne ordinaire places. This Iland of _Cumana_ and _Cubagua_ where they fyshe for these perles, is in the twelfe degree of the part of the said coaste which inclineth toward the North.
