74 Treubia Vol. Ill, l. 



Nearly all the collecting has been done on the northern part of the 

 island. The 25th April 1Q21 we ascended the summit of the island and 

 reached an altitude of 700 M. On the 27th April we tried to put ashore at 

 the southern coast of Sebesy, but the full ocean swelling breaking on the 

 shore here with great power made it too dangerous to stay any longer, 

 and after a very short visit we had to go aboard the ship again. At this 

 point of the island \ could collect only a few insects and some earthworms. 

 At this part of the island there were still to be seen here and there layers 

 of ashes from the Krakatau eruption. 



On Sebesy a total of 638 species were collected against 573 on Krakatau, 

 a difference of small importance. 



Of mammals only one more species than on Krakatau was found, if we 

 exclude at least the cattle and goats which have grown wild on the island. 

 These ruminants were introduced on purpose and we are indebted to the 

 "Gezaghebber" (an offical of the Civil Service) of Kalianda, Lampongs, 

 for the following narrative about their origin. 



He writes as follows : — "Sebesy remained uninhabited until 1890 ; in that 

 year Hadji Djamaludin and a great number of coolies went to the island 

 to clear the land. Having laid it out he introduced about 20 years ago 

 (about 1900) fifteen head of cattle on Sebesy and later on 20 goats and five 

 horses. All these animals were housed in stables but about 10 years ago 

 (about 1910) some of them managed to escape. They have become wild and 

 spread over the whole island and nowadays they are fairly abundant. 

 When the above mentioned Hadji came to Sebesy in 1890, there was only 

 a scanty vegetation, but many trees were planted by him." 



The plantations on Sebesy are chiefly of cocoanuts fringing in a rather 

 large border the north coast of the island. Further there are some fruit 

 trees, and regularly "ladangs" (temporary rice-fields in cleared wood) are 

 laid out. However, a permanent population does not exist on the island, 

 the people coming and going continually from and to the Sumatra coast. 

 Only those who gather the cocoanuts remain for longer periods on the 

 island. 



As fresh meat was always welcome, every time we were at Sebesy one 

 or two of the wild cattle were shot. Only once, April 1921, a goat, a 

 white-haired female, was shot by Mr. SlEBERS at an altitude of 700 M. 

 These beasts do not seem to descend into the plain, remaining always 

 high up in the mountains. 



The number of cattle which had grown wild was estimated at a 

 thousand head. The bulls are of Isabel colour with a dark longitudinal 

 stripe along the back; the cows are brown; also swarthy bulls occur. 



A couple of horses which were running loose were seen sometimes 

 in the neighbourhood of the small bay at the north side of the island. 

 The people told us it was impossible to catch these animals again as they 

 had grown quite wild.
