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 assistance 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 ranté,” 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 ranté,” 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 meuntains 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.
