Klahat Bay. — June 22 to July 3, 1904. The north coast of Banka 

 is fronted b}^ broad beaches of white sand, separated by rocky points. 

 The anchorages are not very good. It is necessary to anchor three- 

 quarters of a mile from shore, as the holding ground is not ver}- good 

 in the hard sand. The coast line is thinly inha})ited, and covered with 

 forest, with a fringe a casuarinas behind the sand tracts. There are 

 a few parits (tin diggings) a few miles inland, and on the coast during 

 the line season a number of Bankanese and Chinese live in temporary 

 huts or shelters, fishing for the supph" of the tin miners. 



The west coast of Klabat Bay near the entrance is covered with 

 heavy forest intersected with many paths made b}' woodcutters. It is 

 mostly rolling country and dry at all seasons, a good place for collect- 

 ing, but the coral reefs project so far from shore that it was a very 

 inconvenient place for me to work, I had to anchor 1^ miles from 

 shore. 



The east side of Klabat Bay is inhabited and for the most part 

 swampy or covered with secondary jungle. Man}' tin diggings occur 

 not far inland. Around the head of Klabat Bay are many villages and 

 tin diggings. 



Tanjong Mciigkudu. — July 8 to 4, 1904. Doctor Abbott made no 

 notes on this locality. It is opposite the small Pulo Mengkudu on 

 the map. 



MENDANAU. 



Pulo Mendmian. — July 14 to 15, 1904. Pulo Mendanau is about 

 8 by 7 geographical miles and lies west of Billiton, separated by a 

 strait 3i miles wide and 10 fathoms deep. Much of the surface is 

 low and swampy. The highest hills are about 600 feet high. There 

 is very little virgin forest left, the jungle being mostly scrubby sec- 

 ondary, and there are large tracts of lalang. Besides the animals 

 obtained, a form of Tragulus I'diwhil is said to exist. It is not found 

 on Billiton. No napu exist and no pigs. 



BILLITON. 



Billiton is about 43 miles square and contains about 1,600 square 

 miles. The surface is mostly low, rolling hills, presenting a flat 

 appearance from the sea, with isolated higher hills. The highest 

 points are Tajem Laki and Tajem Bini, each about 1,770 feet high. 

 The island has been Ij^rgelj' worked for tin during the past fifty-two 

 years, but the production of tin is now diminishing. 



There is no heav}' forest left upon the seacoast, but there is said to 

 be a good deal left in the interior, especially in the south and west. 

 I onl}^ found one small tract of virgin forest, on and around Bukit 

 Menguru, west of Buding Bay. The rest of the island is covered with 

 secondary jungle and tracts of lalang (coarse grass).
