When the great Afonso Dalboquerque was now quite ready to set forth, and all the fleet supplied with everything necessary for the sureness of their voyage, he sent forward, in advance of the vessels, a ship of Chaul, which João Gomez had captured in Çacotorá, having on board twenty Portuguese and a Jew for interpreter, giving them directions to take a pilot for him at the entrance of the straits out of the number of those who dwell there, for he was afraid that if they were to see our whole fleet they would flee away, and he would be left without a pilot. The ship had no sooner arrived at an island which lies at the mouth of the straits than one of these pilots came up and hailed her, and came on board, asking if there was need of a pilot. Then our people came out of their hiding as soon as they had the pilot on board, and laid hands upon him. These pilots are called Rubães; they live at the entrance of the straits, in the island of which I have already made mention. They conduct the navigation from that point inwards, and have great experience of all the shallows and harbours of those parts; and the ships which are making for port inside the straits call at that island for a pilot, paying thirty cruzados for his services as far as Judá.
