A CHIEF OF THE GADDANES, ISABELA, LUZON. No. 17.-One of the most important branches of the insular government is the Bureau of Non-Christian Tribes, whose duty it is to find out the actual conditions of the various non-Christian tribes in the archipelago. These tribes comprise about 2,000,000 people. At present no accurate information is to be had about them. They cover Northern Luzon, Mindoro, Palawan, and the great island of Mindanao. Some of them, like the Negritos, are comparatively harmless, while others, like the Gad danes, are fierce and hard to control. It is said that head hunting is still practiced by the Gaddanes, and that a young man of this tribe cannot find a bride until he has at least one head to his credit.
