If more than one day was spent at a place of anchorage the steam launch was generally 

 made use of, and after finishing the scientiiic operations it was often used for hydrographical 



work. For both these purposes native vessels, called sampans, were often utilised. These were 

 purchased on the voyage. 



As might be expected in this part of the archipelago it happened occasionally that there 

 was iin anchorage at the place where we had decided to stop, at least not anchorage in the 

 usual sense of the word. The voyage was then either continued, as for instance after touching 

 the Widi-group to the east of Halmaheira, or else we continued to drift, as we did when near 

 the island of Kabia (Baars island), in the western part of the Banda Sea. 



Sometimes the chief of the expedition thought it advisable in the interest of the work to 

 make a somewhal prolonged stay at a place of great depth in which case the anchor was attached 

 to the dredgerope. Thus, for instance, we spent three days from November i to 3 on the westcoast 

 of the island Binongka with 500 metres of rope let out, the anchor lying in coralsand at a depth 

 of 278 metres, the distance to the nearest coastreef being about 400 metres. In the same way 

 we stayed on the south side of the Lucipara group in the Banda Sea, from November 8 to 11, 

 with 1000 metres of rope let out, the anchor lying in stony ground about 1500 metres from 

 the nearest reef. At this place whirlpools were formeel with every change of the tide. It was 

 probably owing to these whirlpools and to the rocky nature of the sea bottom, possibly also 

 owing to some extent to the heavy ballast with which the rope had to be weighted at a certain 

 distance from the anchor, that we were unable to free the rope from the bottom and so, 

 unfortunately, lost the anchor and a piece of the rope. 



On these occasions or when the ship was drifting, the officers as a matter of course took 

 their turn in the night watch and steam was kept up. Fortunately for the expedition when we were 

 sailing in parts of the Archipelago where the west monsoon prevailed or was due, this wet season 

 passed over quietly. 



The average speed of the ship was fixed at 7 or 8 knots per hour, thus enabling us 

 to economise coal and not unduly tax the native stokers. As far as could possibly be arranged 

 one engine only was used while the dredging was in progress. 



REMARKS RELATING TO THE APPLIANCES AND 

 IMPLEMENTS FOR DEEP-SEA EXPLORATION AND THEIR MANIPULATION. 



The best works on sounding and dredging were consulted, particularly those of Tanner ] ) 

 and SlGSBEE 2 ). As the nets, thermometers etc. in use were similar in almost every respect to 

 those now generally used in deep-sea exploration, we may take it for granted that the working 

 of them is understood, and the following remarks therefore refer chiefly to the peculiar conditions
