again most kind in forwarding my plans, and from Mr. L. J. J. M. (now 

 Captain) Tabbers, Acting Assistant-Resident at Manokoeari, I met with 

 every sissistance which military training in grasp of the situation, judgment 

 of men, and appreciation of fact and detail could do to ensure success. 

 To Captain J. .F. E. ten Kloosten, who most kindly procured me 

 Dr. Gjellerup's sketch-map of the Angi lakes from the military carto- 

 graphical office at the Wousi Bivouac, with permission to reproduce the 

 same in this work ; to Mr. J. W. Langeler, of the Dutch Navy, attached 

 to the Mamberamo expedition ; and to Mr. F. J. F. van Hasselt, Chief 

 Missionary at Manokoeari, I am further indebted for much help and 

 thoughtful consideration. 



Any difficulty in reaching Wariap, about 60 miles south of Manokoeari, 

 the best point of departure for the mountains, was obviated through the 

 kind offices of Captain J. V. L. Opperman, Commander of the Mamberamo 

 expedition 1913-1914. He gave me, with the escort kindly provided by the 

 Dutch Government, a passage in the Government boat the ' Valk,' which 

 was conveying his expedition to its destination. The ' Valk ' landed us at 

 Waren, 10 miles south of Wariap. 



As there had been recent fighting between the coast and hill people, 

 Mr. Tabbers judged it advisable to send an unusually strong escort, com- 

 prising five Amboinese armed policemen, " Pradjoerit," and ten convicts, 

 " Orang rante," attached to them, to help in the carriage of provisions should 

 the Papuans desert, according to their usual custom. It was no doubt partly 

 owing to these two circumstances that all my carriers remained with me on 

 this occasion ; I noticed great reluctance to stray far from the protection 

 of the guns. 



The sergeant in charge, always called " Serzan," a Timorese, who had 

 served for 20 years through the Achin campaigns, was a. most capable and 

 tireless little man, a thorough soldier, not only very clever in handling his 

 own men, who did him credit, but also in dealing with the Papuans, not 

 such an easy matter. 



The " Orang rante," all enormous men, who made a great impression on 

 the Papuans, turned out very handy and willing. One of them acted as 

 my cook, both in the mountains and until my departure from Manokoeari, 

 while several became quite expert in carrying out botanical processes. 

 It is a great tribute to the humanity of the Dutch rule that men like these 

 Malays, to whom confinement is death, should be sent to expiate their 

 offences, chiefly crimes due to jealousy and gambling, in outlying stations, 

 where they have congenial work under easy and almost independent 

 conditions. Escape is out of the question, as the Papuans shoot at sight 

 any stragglers in the forest so it is not even necessary to guard them, while 

 the best behaved are allowed to earn money by gardening or acting as 

 " boys " to the civil and military officers.
