In the Annual Report of the Botanical Gardens of Buitenzorg 

 over 1896, p. 23, Treub made the following statement (translated): 

 ,,From a trip to Lang Bland, situated near Krakatao, Dr. Boerlage, 

 ,,then subdirector of the Botanical Gardens, brought a small collect- 

 Jon of plants to Buitenzorg. This collection, together with another 

 ,,one made by lieutenant N o I t h e n i u s, then stationed at the island, 

 ,,gives a complete survey -as far as Phanerogams and Vascular 

 ,,Cryptogams are concerned - of the young vegetation developed 

 ,,on that island, after the eruption". 



The same trip is mentioned in the lijdschrift of het Koninklijk 

 Nederlandsch Aardrijkskundig Genootschap (Journal of the Royal 

 Dutch Geographical Society) XIV (1897), p. 118 seq. From an essay 

 by J. J. A. Mulder the following may - in translation - be cited here: 



From June 26th till July 2nd 1896 some officials of the Triangu- 

 lation-brigade stayed on Krakatao charged with seeking a way to 

 the summit which is about 800 m. high. Along different paths they 

 tried to reach the top but all efforts failed. Notwithstanding very 

 much trouble they were not able to get higher than a few hundred 

 meters. The entire mountain ') is covered with a layer of ashes 

 some tens of meters thick, into which deep ravines have been eroded 

 by the rains. When ascending the mountain the visitors followed 

 the narrow ridges between the ravines but all of these appeared to 

 be broken at one or more spots by slides which could not possibly 

 be crossed by means of the ladders the visitors carried with them. 

 Even if these had been equipped much better the dangers would 

 have been enormous, because everywhere the loose materials threat- 

 ened to come down. As they did not intend to make a record of 

 break-neck tours they stopped their efforts. 



Instead of on Krakatao a pillar was erected on Lang Eiland, at 

 a height of about 130 m. on the ridge extending throughout the 

 island. There the difficulties were by far not so great. 



Towards the close of August Lang Hiland was occupied as a 



') One should bear in mind that only tlie lower parts of the island were reached, 

 so that this statement only holds good for these lower parts.
