 senere taime Skitser. 



Mod Nord kunde ingen fremtrædende Træk i Land- 

 skabet sees under Taageranden. Paa Tilbagevejen til Lan- 

 dingspladsen fulgte jeg en liden Bæk mellem de to nævnte 

 Kratere i Syd for Mary Muss Bugten. Den forsvandt i 

 Sandet førend den naaede Havet. Kra dette Punkt teg- 

 nede jeg Skitsen til Fig. 1. der viser "Fugleberget" fra 

 Siden, til Venstre af samme Havet, til Højre den vestlige 

 Lagune. 



Samme Formiddag samlede Dr. Danielssen Planter 

 paa Højderyggen og paa Skraaningen af det større Krater 

 i Krater Danielssen) i Syd for Landingspladsen. En Polar- 

 r.-ev. der blev opjaget paa Højderyggen eller Ejdet, blev 

 skudt med Expressrifle af Lieutenant Petersen. 



Det rolige Vejr vedvarede om Ettermiddagen, og nye 

 Excursioiier foretoges i Land. Fra Landingspladsen gik 

 jeg først over den indre og ydre Skrå aning af Fuglebergets 

 Affald mod Sydost. og derpaa tilvenstre i Dalen indenfor 

 Fugleberget, indtil jeg naaede den vestlige Lagune. For 

 at komme fra Lagunens sydlige Strand hen til den Tange, 

 som skiller den fra Havet, maatte jeg passere en Ur af 

 tildels sture skarpkåntede Lavablokke, der her danner Over- 

 fladen af "Fuglebergets" mod Lagunen vendende Fod. 

 Lagunen har ferskt Vand. I )en er saa dyb, at Bund ikke 

 kunde sees paa en kort- Afstand fra Stranden. 



Tannen, som skiller Lagunen fra Havet, var 200 

 Skridt (14() Meten bred. Dens højeste Ryg laa, efter 

 Maaling med Aneroidbarometer. 8 å 9 Meter over Havets 

 Nive.iu. Lagunvandets Niveau laa 5 å 6 Meter under 

 Tangens Ryg, eller omtrent 3 Meter højere end Havets 

 Niveau. Paa Tangen laa megen Etsekved og mange Hvirv- 

 ler og Kjæver af Hval. Der fandt jeg ogsaa et Flotholt, 

 c LO Cm. langt, 7 Om. bredt, 2 Cm. tykt, af Hark. For- 

 skjellige Stykker bredbladet Tang laa opskyllede paa Yder- 

 iten af samme Vold. Dennes Længde ansloges til en 

 Kvartmil og Lagunens Bredde til lienimod det samme. 

 Der saaes Rækved liggende ogsaa paa Lagunens sondre.

 of low-lying foreshore. forming the inner boundary of the 

 long eastern "lagoen. • Looking east from the heights ahove, 

 I bad -befare me the -'Ægøen" (Egg-Island) peninsula, with 

 its "calf" — small detacbed islet (Fig. '2i In the south-west, 

 we could siglit beneath -the fog the east coast of the southern 

 part of Jan Mayen, with the lagoon and its barrier, and. 

 rising abruptly from the sea. two isolated rocks, known as 

 "Lodsbaaden" (the pilot boat) and "Fyrtaarnet" (the light- 

 house). Mr. Schiertz has given in the plate an excellent 

 view of this hue coastal scenery, sketched from the ridge 

 overbooking the sea. The mountain summits having, as 

 previously remarked. been wrapped in elouds on our arri- 

 val, that part of the picture was filled in from sketcbes 

 tåken a day or two later from our anchorage on the east 

 side of the island. 



North, no prominent feature of the scenery could he 

 discerned below the fog. On my way back to the landing- 

 place. I followed the course of a rivulet between the two 

 craters south- of Mary Muss Bay. Before reaching the sea, 

 tli iss little stream was lost in the sand: and here I sketched 

 the "Fugleberg" — a side-view. to the left the ocean, 

 to the right the western lagoon ( Fig. 1 ). 



The same afternoon Dr. Danielssen collected speci- 

 mens of the insular flora on the mountain ridge and on 

 the slope of the great crater (Danielssens crater), south of 

 the landing-place. A polar fox. roused. I believe, among . 

 the rocks of the mountain ridge. or on the isthmus. was 

 shot by Lieutenant Petersen with an "Express" rifle. 



The weather still continuing fine. further excursions 

 were made in the afternoon. From the landing-place I 

 took a south-easterly direction. crossing the south-western' 

 ridge of the Fugleberg, and then, turning to the left. struck 

 off down the valley on the shore-side of the clifl'. till I 

 came to 'the western lagoon. In making my way from the 

 south shore of the lagoon to the strip of land stretching 

 between it and the sea. I had to pass an incline of debris 

 over part of whicb were dispersed large, sharp-edged blocks 

 of lava. that hereabouts form the hase of the fowling-cliff

The barrier separating the lagoon trom the sea
