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 Yogt’s 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 Yogt’s Beretninger er kommen til det bestemte
Resultat, at disse Forskere have besteget forskjellige Kratere.
Vogt beretter nemlig, at hau besteg Scoresby’s Krater Esk.
De ældre Karter give ingen Vejledning, da disse
Gjenstande ikke ere af nogen hydrografisk Interesse. Scoresby
siger (I, Side 1(52), "at han fra Krater Esk saa ved Foden
af Bjerget paa Sydostsiden, i Nærheden af en Vældig
Lavastrækning, 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 låve Forland det låve Askekrater
"Berna", der ueppe hæver sig over Sletten, og paa Vogt’s
Kart er Scoresby’s andet Krater udeladt og "Berna" sat
istedet. Efter hvad jeg, soin ovenfor nævnt, til forskjellige
Tider kunde se, findes alle 3 Kratere, saaledes som paa
vort Kart angivet. Der er i Vogt’s Beskrivelse, saavidt
jeg kau 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 Gråd har udvidet vor Kundskab om denne 0, og
hvis Beskrivelse deraf havde orienteret mig i Forvejen i den
Grad. at jeg under vort Besøg 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. Vogt’s Kart forbinder den med Land
ved en ganske smal Tange. Vi saa den som en
fuldstændig Halvø. Man se Fig. 2 og Kartet. Scoresby’s Cape
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 saavel her som i Zorgdrager’s og
i Scoresby’s Verker. Paa Vogt’s Kart er den bleven
ucle-glemt. Den korte Beskrivelse i •’Zeespiegel" stemmer godt
med mine Iagttagelser paa Stedet. Den lange Lagune paa
Østsiden derimod findes ikke i nogen af de ældre Beskri-
Off the coast, the navigation is here, according to the
earlier accounts, a good deal incumbered with rocks and shoals;
and hence, possibly, the old whalers of the 17th century did
not attach any hydrographical importance to the glacier.
It is however 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 Vogt’s
account 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 Scoresby’s and
Vogt’s accounts, that the said explorers must have ascended
different craters. According to Vogt’s statement, lie ascended
the Esk crater (Scoresby’s). The earlier maps afford no
assistance in deciding this doubtful point, since such details, being
without hydrographical interest for the navigators of that
time, were not laid down. Scoresby, who had ascended
the Esk crater, states (page 1(32), that -’at the foot
of the mount, on the south-east side, near a stupendous
accumulation of lava, bearing the castellated form, was
another 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 lie had ascended, Vogt saw
beneath him, on the low-lying foreland, the low Berna
crater, which hardly rises above the surrounding tract: and
on Vogt’s map Scoresby’s second crater has been left out
and the Berna crater substituted in its place. As
previously stated, according to what I observed at different
times, all 3 craters are to be found, in the respective
positions given them on our map. In Vogt’s account thgre is
nothing, so far as I can judge, to oppose our assuming that
the cone which Scoresby distinctly observed from the
summit of Mount Esk is that ascended by Vogt. I have
likewise 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
topography, 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
Zorgdrager and Scoresby, Egg Island is represented as a
veritable island, cut off by a sound from the main land. On
Vogt’s map, an exceedingly narrow strip of.land connects,
it with the main island. As ive beheld. "Egg Island," it was in
every respect a peninsula: see Fig. 2 and the Map. Scoresby’s
Cape Brodrick, the point lying within the sound, must
accordingly 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
account 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 Vogt’s map it has
been left out. The brief description in the -’Zeespiegel"
agrees closely with my own observations. On the other
