They have few religious practices, although they believe in a Supreme Being, and in the ancestor-worship common to the country. The relatives assemble to celebrate a birth by a feast. On the fifth day a name is given to the infant. They take care of the sick and endeavour to cure them with herbs, to which they ascribe medicinal virtues. If the patient dies, the relatives devour everything in the house in order to mitigate their grief, and they bury the corpse within twenty-four hours of death, placing some provisions upon the grave. From a statement in a Spanish official publication, the Ilongote dialect is spoken in two towns and twenty-two rancherias of Nueva Vizcaya, and in four rancherias in the district of Principe. This shows that at least on their western border they are now somewhat held in check. But the poor Negritos still have to suffer their incursions. Mayoyaos and Silipanes (16). These people are very numerous, and inhabit the north-west corner of Nueva Vizcaya, and the south-west corner of Isabela, between the Cordillera Central and the River Magat. For neighbours, they have on the east the Ifugaos, those deadly lasso-throwers; on the west, the Igorrotes are separated from them by the Cordillera; to the north they have the Gaddanes, and the Itetapanes, and to the south the Italones. In appearance, dress, arms and ornaments, they resemble the Igorrotes of Lepanto. The Ifugao language is spoken at the missions of Quiangan and Silipan, and in a large number of hamlets of these people. They were pacified and converted to Christianity about half a century ago, and are gradually improving in civilisation. Ifugaos (17). The Ifugaos, who bear a strong resemblance to the Japanese, inhabit a territory in central Nueva Vizcaya, and in the south of Isabela, mostly between the River Magat and the Rio Grande, but they have a great many hamlets on the left bank of the Magat. They cultivate rice, camote, and other crops, but prefer to live by robbery whenever possible. They are persistent head-hunters, frequently at war with the neighbouring tribes, or amongst themselves. One notable peculiarity must be mentioned. Besides the lance, knife, and bow and arrows, they use the lasso, which they throw with great dexterity. Lurking near a trail, they cast the fatal coil over some unwary traveller, and promptly decapitate him, to add his skull to their collection, and decorate their hut. It is their custom to wear as many rings in their ears as they have taken heads. Major Galvez, after a skirmish with these people, found the corpse of one of their warriors who wore thirty-two death-rings in his ears.
