[The following is taken from vol. v, pp. 343–390 (mainly verbatim) of Charles Wilkes’s16 Narrative of the United States Exploring Expedition during the years 1838, 1839, 1840, 1841, 1842 (Philadelphia, 1844). It is one of the earliest accounts written by an American of the island of Joló and its vicinity, and the Joloans. Although containing considerable matter that is descriptive rather than ethnological in character, it has been deemed advisable not to endeavor to separate the matter, in view of its value. Wilkes writes mainly as an eyewitness.]
