den- lange Lagune. Ogsaa her var Yandet ferskt, men 

 Lagunen var meget grundere end Vestsidens. Der laa 

 Rækved. saavel paa Lagunvolden som paa den indre Strand. 



Den følgende Dag arbejdede Zoologerne med Skrab- 

 ning fra Baad i Mary Muss Bugten. Fra vor Ankerplads 

 toges Skitser, navnlig af Landet mod Vest. Disse ligge 

 til Grund for Fig. 3. der viser Udseeudet af det Nes. der 

 begrændser Nordostsiden af Nord-Baj eller English Bay. 

 Yderst ser man den isolerede hoje Klippe, som af de 

 gamle Hollændere er kaldt "Brielle-Taarnet" og som danner 

 et udmerket Sømerke. Mellem "Taarnet" og Landet inden- 

 for er en dyb Kløft, som paa de ældste Karter kaldes 

 "Walrusch Grat".- Billedets Synspunkt er tænkt paa den 

 vestlige Laguntange. strax i Nordost for Fugleberget, bvis 

 bratte Skrænt sees til venstre i Forgrunden. Brielle Taar- 

 net ligger tre Gange saa langt borte som "Vøringen". 



Da vi om Ettermiddagen gjorde os istand til at gaa 

 i Land for at undersøge Landet længere sydpaa, rejste sig 

 en frisk Bris af Nordvest, der satte saa megen Sø. at 

 Landgang blev vanskelig. Det besluttedes da at sejle om 

 til den anden Side af Øen. . Under Letningen kom Solen 

 et Par Gange frem i Vest. saa at dens Højde kunde maales. 

 Paa den anden Side. mnd •Nordost, rev Vinden enkelte 

 Gange Hul i Taagen. og Toppen af Beerenberg viste, sig i 

 nogle Secunder. ophojet og vidunderlig skjon i sin blæn- 

 dende hvide Snekaabe. Dens Højde blev maalt med Sex- 

 tant. Vi styrede NNV. over. Saa ofte som Beerenberg 

 var synlig, benyttedes de koi'te Stunder til at fæste dens 

 Udseende i Skitsebøgerne. Effcer disse Skitser er Fig. 4 

 tegnet. Forholdet mellem de verticale og horizontale Ud- 

 strækninger er det rigtige og stemmer med Kartet. Store 

 sorte Flekker, paafaldende mørke ved Contrasten med den 

 blændende livide. af Solen oplyste Sne. viste bratte Styrt- 

 niiiger paa den ovre Kegle, hvor Fjeldet var ganske bart. 

 Da vi. kom længere frem. stak to Afsatser. den ene uden- 

 for (nordenfor) og nedenfor den anden, sig frem mod Nord 

 — se Fig. 4 — saa kom Taagen og tilhyllede atter alt 

 undtagen det laveste af Landet til 90 å 100 Meters' Højde. 



Inder hele Farten denne Ettermiddag og Aften rundt 

 (lens Nordende toges stadig Pejlinger med Compasset til 

 alle synlige Pynter og andre, merkelige Gjepstande, og der 

 maaltes Vinkler med Sextant. Ogsaa til Punkter paa Sul- 

 landet, der under den første Del af Farten saaes helt nede 

 indtil Hoyberg, toges Sigter. Kursen styredes og bereg- 

 nedes med Nøjagtighed og Loggemaskinen observeredes 

 liveri femte Minut. Der toges ved Siden heraf en Elække 

 Skitser. Det saaledes indvundne Materiale er i fuldt Maal 



lagoon. Here. too. the water was fresh. though the lagoon 

 was much shallower than that on the west side. Drift- 

 wood lay scattered alike on the barrier and on the inner 

 strand. 



On the following day our zoologists dredged from a 

 boat in Mary Muss Bay. Sketches .were made from the 

 anchorage. chiefly of tbe land stretching west ; and these have 

 furnished the subject of Fig. 3. wbich gives a view of the 

 headland forming the. north-eastern extremity of North or 

 English Bay. In the distance is seen the lofty isolated 

 rock palled by the early Dutch navigators -'Brielle Tower." 

 .and which serves as an excellent land-mark. Between the 

 "Tower" and the main land extends a deep ravine, that 

 bears on the earliest maps the name of "Walrusch Gat." 

 The point of view in the figure is supposed to be on tbe 

 barrier of the western lagoon, north-east of the Fugleberg, 

 which. with its steep acclivity, rises boldly in the left fore- 

 ground. Tbe distance of Brielle Tower from the point of 

 view is thrice that of the "Vøringen.'' 



In the afternoon, as a party of us were getting ready 

 to go ashore, with a view to explore the island farther 

 south, a fresh breeze sprang up from the north-west, and soon 

 made so rough a sea ttiat landing was out of the question. 

 We determined therefore to steam round to the opposite 

 side of the island. While getting under weigh. the sun 

 broke out twice in the west. and we managed to take a 

 couple of altitudes. Now and again. on the other side. in 

 the north-east. the wind tore a rent in the clouds. and for 

 a few seconds disclosed the dazzling, snow-capt summit 

 of Beerenberg, in matchless grandeur and beauty. The 

 height of the moimtain was measured with the sextant. 

 We steered north-north-west. So often as any part of Mount 

 Beerenberg became visible for a moment, the brief oppor- 

 tunity was eagerly seized ' to tix some new feature of 

 its fleeting aspect. Fig. 4 is from these sketches. The 

 proportion between the vertical and tbe horizontal extent 

 of the mountain is true to nature, and agrees with the 

 Map. Huge black patches on the upper cone. rendered 

 doubly conspicuous by contrast with the dazzling white of 

 the sun-illumined snow, showed the position of the steepest 

 inclines. where the mountain was entirely naked. Farther 

 on. two rocky ledges, the one bey ond (north of) and below 

 the other. could be seen projecting northward (Fig. 4): - 

 and then came the fog. blotting out everything from view. 

 save the lowest strip of coast. that was still visible for 

 about 300 feet above the sea. 



During the whole of that afternoon and evening. as 

 we steamed round the nor.thern extremity of the island, 

 bearings by the c-oiupass were successivelv tåken of all 

 visible headlands and other salient landmarks: and angles 

 were measured with, the sextant. Of points on the south 

 part of JanMayen, that for some time alter starting could 

 be seen ns far as Hoyberg. bearings were also tåken. The 

 ship's course was accurately computed, the water-log being 

 observed everv live niinutes. Moreover. a series of sketches
