esse for de .gamle Hvalfangere i det 17de Aarhundrede, 

 men paafaldende er det unegtelig. at Scoresby. der roede 

 langs denne Kyst den 4de August 1817 og var iland paa 

 Toppen af Krater Esk samme Dag, ikke omtaler denne 

 betydelige Bræ, der danner et saa fremtrædende Træk i 

 Landskabet. Se Vogts Beretning og vort Billede. Er 

 ogsaa den en nyere Tids Dannelse? 



Med Hensyn til Krater Esk og Krater Vogt maa jeg 

 bemerke, at jeg efter nøjagtig Gjennemgaaen af Scoresby's 

 og Vogts Beretninger er kommen til det bestemte Resul- 

 tat, at disse Forskere have besteget forskjellige Kratere. 

 Vogt beretter nemlig, at han besteg Scoresbys Krater Esk. 

 De ældre Karter give ingen Vejledning, da disse Gjen- 

 stande ikke ere af nogen hydrogratisk Interesse. Scoresby 

 siger (I, Side 1(32), -'at ban fra Krater Esk saa ved Foden 

 af Bjerget paa Sydostsiden. i Nærheden af en vældig Lava- 

 strækning, et andet Krater med Rand som en Murtinde. 

 af lignende Form som det ovenfor beskrevne (Esk)." Begge 

 Kratere ere angivne paa hans Kart, det vestligste betegnet 

 ••Esk Mount. a Volcano". Vogt saa fra det Krater, han 

 besteg, nede paa det lave Forland det lave Askekrater 

 •'Berna", der neppe hæver sig over Sletten, og paa Vogfs 

 Kart er Scoresby 's andet Krater udeladt og "Berna" sat 

 istedet. Efter hvad jeg, som ovenfor nævnt, til forskjellige 

 Tider kunde se. rindes alle 3 Kratere, saaledes som paa 

 vort Kart angivet. Der er i Vogts Beskrivelse, saavidt 

 jeg kan se, Intet i Vejen for at antage, at det Krater, 

 Scoresby saa tydelig fra Toppen af "Esk", er det, som 

 Vogt har besteget. Jeg har ogsaa tilladt mig at give dette 

 Krater Navn efter denne Forsker, hvis Rejse til Jan Mayen 

 i saa høj Grad har udvidet vor Kundskab om denne 0, og 

 hvis Beskrivelse deraf havde orienteret mig i Forvejen i den 

 Grad, at jeg under vort Besog der havde en Følelse, som 

 om det var en tidligere kjendt Egn, jeg var kommet til. 



Ægøen er i "Zeespiegel', hos Zorgdrager og hos 

 Scoresby fremstillet som en fra Hovedlandet ved et Sund 

 adskilt virkelig 0. Vogfs Kart forbinder den med Land 

 ved en ganske smal Tange. Vi saa den som en fuldstæn- 

 dig Halvø. Man se Fig. 2 og Kartet. Scoresby's Gape 

 Brodrick, Pynten indenfor Sundet, er saaledes forsvundet 

 mellem 1817 og 1861, idet Øen er bleven forbundet med 

 Land. Landtangen, der nu er lige saa bred som Ægøen 

 selv, ligger adskillige Meter over Havspejlet. 



Lagunen paa Vestsiden omtales i "Zeespiegel" og. 

 forekommer paa Kartet såavel her som i Zorgdrager's og 

 i Scoresby's Verker. Paa Vogfs Kart er den bleven ude- 

 glemt. Den korte Beskrivelse i "Zeespiegel" stemmer godt 

 med mine lagttagelser paa Stedet. Den lange Lagune paa 

 Østsiden derimod tindes ikke i nogen af de addre Beskvi- 



Off the coast, the navigation is here, according to the 

 earlier aceounts, a good deal incumbered with rocks and shoals; 

 and hence. possibly, the old whalers of the 1 7 th Century did 

 not attach any hydrographical importance to the glacier. 

 It is hovever undeniably strange, that Scoresby, who on 

 the 4th of August rowed along this part of the coast, and 

 the same day ascended to the summit of Mount Esk. should 

 not have mentioned so considerable a glacier. forming as 

 it does a prominent feature of the scenery (see Vogts ac- 

 count and our view). Can this. too, be a later formation? 



As regards the Esk crater and the Vogt crater. I 

 feel convinced, from a careful perusal of Scoresbys and 

 Vogts aceounts, that the said explorers must have ascended 

 different craters. According to Vogfs statement, he ascended 

 the Esk crater (Scoresby s). The earlier maps afford no assis- 

 tance in deciding this doubtful point, since such details, being 

 without hydrographical interest for tlie navigators of that 

 time, were not laid down. Scoresby, who had ascended 

 the Esk crater. states (page 162), that "at the foot 

 of the mount, on the south-east side, near a stupendous 

 accumulation of lava. bearing the castellated form, vas an- 

 other crater, of similar form to the one above described." 

 Both craters are to be found on his map, the most westerly 

 of the two being designated "Esk Mount. a Volcano." 

 Looking down from the crater he had ascended, Vogt saw 

 beneath him, on the low-lying foreland, the low Berna cra- 

 ter. which hardly rises above the surrounding tract : and 

 on Vogfs map Scoresbys second crater has been left out 

 and the Berna crater substituted in its place. As previ- 

 ously stated, according to vhat I observed at different 

 times, all 3 craters are to be found. in the respective posi- 

 tions given them on our map. In Vogfs account there is 

 nothing. so far as I can judge. to oppose our assuming that 

 the cone which Scoresby distinctly observed from the sum- 

 mit of Mount Esk is that ascended by Vogt. 1 have like- 

 wise made free to give this crater the name of the explorer 

 whose voyage to Jan Mayen has so largely contributed to 

 extend our knowledge of that interesting island. and whose 

 accurate account had rendered me so familiar with its topo- 

 graphy, that during our sojourn there I had frequently the 

 impression of being in a country I had visited before. 



Both in the "Zeespiegel" and in the maps by Zorg- 

 drager and Scoresby, Egg Island is represented as a veri- 

 table island, cut off by a sound from the main land. On 

 Vogfs map. ah exceedingly narrow strip of land connects, 

 it with the main island. As we behehl "Egg Island." it was in 

 every respect a peninsula ; see Fig. 2 and the Map. Scoresby's 

 Cape Brodrick, the point lving within the sound, must ac- 

 cordingly have disappeared some time between the years 

 1817 and 1861. The isthmus. which is now equal in 

 breadth to Egg Island itself, rises a score or so' of feet 

 above the sea-level. 



The lagoon on the west side is mentioned in the ac- 

 count of the island given in the "Zeespiegel," and may be 

 found on the map accompanying that work, as also on the 

 maps by Zorgdrager and Scoresby. On Vogfs map it lias 

 been left out. The brief description in the "Zeespiegel" 

 ågrees closely with nry ovn observations. On the other
