It is noteworthy that the Spaniards when they landed fought with crossbows and arrows, which were in those days much more effective weapons than the guns of the period. The Micronesian people they met on the Island of Guam they described as going naked, many of the men being bearded and having black hair that reached to the waist. They wore small palm-leaf hats, were as tall as the Spaniards, well-built and of tawny skin, with teeth turned red and black by the chewing of betel. The women, who were good-looking, delicately formed, and much lighter in complexion than the men, had black hair which was worn loose and reached almost to the ground. The women did not work in the fields but stayed at home, weaving mats and baskets from palm leaves. The mats were beautifully made and used to decorate the walls and the floors of their houses. They slept on palm straw, which was soft and fine. Their houses were built of planks and thatched with banana fronds. The food of the people was chiefly coconuts, sweet potatoes, fowls, bananas (really long plantains 1 foot in length), sugar cane, and flying-fish. The chief amusement of both men and women was to plough the seas with their small boats, which were usually painted black, white, or red. Pigafetta describes the outriggers, and says the sails were made of palm leaves.[27] Having no fixed rudder, but only using a long paddle for such a purpose, and the boats being sharp at both ends, they could be sent backwards or forwards without turning round.[28] [27] Magellan first gave to the Ladrone Islands the name of Islands of Sails, on account of the many vessels with sails which he observed in that neighbourhood, showing how firmly established among the Polynesians and Micronesians was the use of the sail in their navigation, a fact which explains the success of their voyages over enormous sea distances. [28] They were similar to the prahus or praus of Malaysia, which did not turn round, but sailed backwards and forwards, the sharp stem being exactly like the sharp stern. Most of the prahus had outriggers, and in all the leeside of the vessel was flat and perpendicular while the weatherside was rounded. The mast carried a large triangular-shaped sail. At dawn on 16 March, 1521, the expedition sighted high land. This was the Island of Samar, on the eastern side of the Philippine archipelago.
