 Manila, he accepted the post and bade good-bye to his native 

 land. 2 



He remained with this firm for three years and indicated his 

 interest in the exploration of the Islands by a number of excur- 

 sions into the interior, visiting among others the Negritos of 

 Bataan, Zambales, and Pampanga. A severe attack of a per- 

 nicious fever compelled him to return to Breslau in 1879, not, 

 however, without having previously worked out with a Manila 

 friend, Otto Koch, a plan for the exploration of southern Min- 

 danao, especially the country around Mount Apo on Davao Gulf. 

 For a while the execution of this plan seemed endangered by 

 Schadenberg's engagement, in the spring of 1881, to a young 

 countrywoman of his. The interest, however, which all parties 

 concerned took in the projected expedition, from which valuable 

 results were expected for science, was sufficient to induce the 

 young couple to agree to a temporary separation. Thus, in 

 August, 1881, supplied with all necessary instruments and with 

 articles of exchange for dealing with the natives, Schadenberg 

 set out again for the Philippines, accompanied by his friend 

 Koch. In Mindanao the Spanish authorities of those days, while 

 ready to lend every possible help, showed themselves sincerely 

 concerned about the safety of the travelers intent on losing 

 themselves in the wilds of the country behind Davao, a region 

 which in parts remains unexplored even to-day. By December, 

 however, the two friends had established themselves beyond 

 the pale of civilization, in the Bagobo village Sibulan, south of 

 Mount Apo, where, in exchange for some coils of brass wire, 

 they had purchased the handsome bamboo cottage of one of the 

 headmen. During their stay here of about six months they 

 made the tribe among which they lived, and which was noto- 

 rious for the practice of human sacrifice, the object of a close 

 ethnographic study, drawing up also a vocabulary of the lan- 

 guage. 8 They assembled an extensive collection, both of ethno- 

 graphic objects and of specimens of the local flora and fauna,
