Note {4} — Chapter XXXIII

Note 4.—De Barros, after describing the dangers of the Channel of Mozambique, adds: “And as the Moors of this coast of Zanguebar make their voyages in ships and sambuks sewn with coir, instead of being nailed like ours, and thus strong enough to bear the force of the cold seas of the region about the Cape of Good Hope, ... they never dared to attempt the exploration of the regions to the westward of the Cape of Currents, although they greatly desired to do so.” (Dec. I. viii. 4; and see also IV. i. 12.) Kazwini says of the Ocean, quoting Al Biruni: “Then it extends to the sea known as that of Berbera, and stretches from Aden to the furthest extremity of Zanjibar; beyond this goes no vessel on account of the great current. Then it extends to what are called the Mountains of the Moon, whence spring the sources of the Nile of Egypt, and thence to Western Sudan, to the Spanish Countries and the (Western) Ocean.” There has been recent controversy between Captain A. D. Taylor and Commodore Jansen of the Dutch navy, regarding the Mozambique currents, and (incidentally) Polo’s accuracy. The currents in the Mozambique Channel vary with the monsoons, but from Cape Corrientes southward along the coast runs the permanent Lagullas current, and Polo’s statement requires but little correction.
