 vi kaldte "Støtten", og som sees saavel paa vort Billede af

 i hele dens Udstrækning, og fra -'Esk" skulde den være 

 lige saa godt synlig. Man tor heretter med Vogt trygt 

 slutte, at Lagunen er dannet mellem hegge Forskeres Besøg, 

 mellem 1817 og 1861. Jeg tror snarere, at den er dannet 

 ved at den lave Sandvold, som adskiller den fra Havet.

 antager, at Lagunens Flade tidligere var dækket af "Bank-

 Havspejlet : tbi Ægoens Landtunge udgjør den directe Fort-

 nogen merkelig Hævning. Paa vor Kundskabs nærværende 

 Standpunkt kunne Gjætninger lige saa lidet hjelpe os her 

 som ved Sporgsmaal om Jan Mayens Isbræers Forandringer. 



De af Havet opragende Klipper "Lodsbaaden" og 



•'Fyrtaamet" ligge efter vore Maalinger og Tegninger som 

 paa vort Kart angivet. De tindes hegge omtalte i "Zee- 

 spiegel" og afsatte paa Kartet deri som "Klip als een Seyl". 

 Deres Beliggenhed er rigtigeré paa det gamle hollandske 

 Kart end hos Scoresby. der hegger "Lodsbaaden" for langt 

 mod Syd og "Fyrtaamet" for langt fra Land.

liainl. the long lagoon on the east side is not mentioned 

 in the earlier accounts of Jan Mayen, nor does it appear 

 on any of tlie annexed maps. ln the "Zeespiegel." this 

 part of tlie coasl exhibits two long hights, — Great Wood 

 Bay and Little Wood Bay ("Groote Hout hav" and "Cleyne 

 Hout bay"), disconnected by a rocky mass stretching be- 

 tween tliein down to the sea. It is evidently tliis cliff to which 

 we have given the name of "Søjlen" (the pillar), and which 

 appears both in our view of the lagoon and in that 

 given on page 282 of Vogfs work. In the "Zeespiegel," 

 the bay lias a flat san dy beach covered with driftwood, and 

 the water is shallow — 6. 7. and 8 fathoms — to the 

 distance of a mile and a half from the shore. The 

 same details are given in the maps by Zorgdrager and 

 Scoresby. Scoresby states, that from the suminit of Mount 

 Esk. "towards the south-west the utmost extent ot the is- 

 land was visible;" but he does not say a word a hout the 

 lagoon. nor is that prominent feature of the coast to be 

 found in his map. From the top of the crater bearing his 

 name. Vogt could overbook the lagoon in its full extent, 

 and the same should be tlæ case from the sftinmit of Mount 

 Esk. Hence. it would be reasonable to inter with Vogt, 

 that the lagoon has been formed between the visits of the 

 two explorers, or some time during the interval extending 

 from 1817 to 1861. Meanwhile, the origin of the lagoon 

 must, I think. be ascribed to the low sand-harrier stretch- 

 ing between it and the sea having been gradually thrown 

 up by the action of the surf, rather than, as Vogt sur- 

 niises, to -the possible fact of its surface having in former 

 times been covered with "bank-ice.' : The conversion of 

 Egg Island to a peninsula is beyond doubt closely con- 

 nected with the appearance of the lagoon barrier abové the 

 sea-level, since the Egg Island isthmus constitutes the direct 

 continuation of the said barrier. True, there may have 

 been a rise along this part of the coast; but on the other 

 side of the island, if the account given in the -'Zeespiegel"' 

 from the middle of the 16th century be compared with the 

 results of my own observations, there can hardly have been 

 a perceptible rise at the barrier of the western lagoon. 

 At the present stage of research, hypothetical deductions 

 are as futile here as in questions bearing on a presumptive 

 change in the number and position of Jan Mayen's glaciers. 



The two rocks rising abruptly from the sea called 

 respectivejy the "pilot-boat" and the "light-house." have, 

 according to our observations and drawings, the position 

 given them in the annexed Map. They are both mentioned 

 in the "Zeespiegel."" and laid down on the map acconi- 

 panying that work as "Klip als een Seyl." The old Dutch 

 geographer has placed these rocks more correctly than 

 Scoresby. on whose map the -pilot-boat" lies too far south 

 and the "light-house"' too far from the shore. 



The most northerly point of Guinea Bay projects. 

 according to our drawings, farther out than it does on 

 Scoresby 's map. In this detail' we agree hetter w : ith the 

 "Zeespiegel." 



Vogel-klip lies according to the "Zeespiegel" just 

 without the west point of South Bay, not as on Scoresby's 

 map to the south- west of that bight, "When anchored in
