TanjoiKj Rengsaiii. — May 20 to 2S, 190-1:. The coast at Tanjong 

 Rengsam is rather flat, with low hills in the interior. The neighbor- 

 hood is mostly covered with secondary jungle and patches of lalang 

 grass. There is one piece of heavy foiest on the seashore, covering 

 about 1 square mile, which has been preserved by the Bankanese for 

 the sake of the timber. Some small plantations of cocoanuts are on 

 the shore. Only four or five families live here. At the mouth of the 

 Jering River, 3 miles away, is the large kampong [village] of Nyor. 

 The natives are all Bankanese. 



Tanjong Tedong. — May 31 to June -1, 1901:. At Tanjong Tedong 

 is a bluff extending along the seashore. Most of the neighborhood is 

 covered with secondary jungle, the swampy land onl}^ being covered 

 with heav}^ forest. The small kampong of Tanjong Tedong lies on 

 the shores of the strait opposite Pulo Nangka Besar [not shown on the 

 map]. The inhabitants are Bankanese. 



Tanjong Bedaan and Parmissan. — June 6 to 15, 1901. Tanjong 

 Bedaan (Bedaan on the charts) is a rocky point, the neighborhood 

 mostly covered with secondary jungle, much of it old. A good deal 

 of tin mining is carried on in the neighborhood. The large kampong 

 (100 houses) of Parmassan (or Parmissan) lies about a mile inland, in a 

 northeast direction. Bukit Parmissan is a range of hills, 5 or 6 miles 

 long, lying 2 or 3 miles back from the sea. Its highest point is 1,600 

 feet, and is the second highest peak in Banka. The lower slopes of 

 Parmissan Hill are covered with small jungle or dense scrub, at least 

 the parts nearest the kampong, but the upper parts are covered with 

 high open forest. Kampong Pai-missan is inhabited by Sumatran 

 Malays. Most of the parits, or tin diggings, are situated on the sea- 

 shore, and a number of Chinamen live there. 



Tanjong Faimija.— June 17 to 21, 190.1. Doctor Abbott made 

 no special notes on this place. His account of the north shore of 

 Banka is under Klabat Ba}^, below.
