velser eller Karter. "Zeespiegel" har paa dette Sted to
lange Bugter. Store og lille Rækved-Bugt "("Groote Hout
bay" og "Cleyne Hout bay"), adskilte ved en til Havet
gaaende Bergmasse. Denne er aabenbart den samme som
vi kaldte "Støtten’’, og som sees saavel paa vort Billede af
Lagunen som paa det tilsvarende Billede Side 282 hos
Vogt. I Bugten har "Zeespiegel" en Had Fjære af Sand.
dækket med Rækved, og i Havet udenfor er der temmelig
grundt. 6, 7 og 8 Favne indtil l1/-. Kvartmil fra Stranden.
Zorgdrager og Scoresby har det samme. Scores"by fortæller,
at, da han var paa Toppen af "Esk", "var. mod Sydvest,
hele Øens Udstrækning synlig", men nævner ikke et Ord
om Lagunen, og har den heller ikke paa sit Kart. Fra
Toppen af sit Krater beretter Vogt. at lian saa Lagunen
i hele dens Udstrækning, og fra "Esk" skulde den være
lige saa godt synlig. Man tør herefter med Vogt trygt
slutte, at Lagunen er dannet mellem begge Forskeres Besøg,
mellem 1817 og 1861. Jeg tror snarere, at den er dannet
ved at den låve Sandvold, som adskiller den fra Havet,
efterhaanden er opkastet af Brændingen, end, som Vogt
antager, at Lagunens Flade tidligere var dækket af
"Bank-isen". Ægøens Forbindelse med Land staar aabenbart i
nøjeste Forbindelse med Lagunvoldens Fremkomst over
Havspejlet; thi Ægøens Landtunge udgjør den directe
Fortsættelse af Lagunvolden. En Hævning af Landet her er
ikke utænkelig, men paa den anden Side af Øen. vecl den
vestre Lagunes Vold. er.der, naar "Zeespiegel"s Beskrivelse
fra Midten af det 16de Aarhundrede sammenholdes med
mine ovenfor nævnte Iagttagelser, ikke noget Tegn til
nogen merkelig Hævning. Paa vor Kundskabs nærværende
Standpunkt kunne Gjætninger lige saa lidet hjelpe os her
som ved Spørgsmaal om Jan Mayens Isbræers Forandringer.
De af Havet opragende Klipper "Lodsbaaden" og
"Fyrtaarnet" ligge efter vore Maalinger og Tegninger som
paa vort Kart angivet. De tindes begge omtalte i
"Zeespiegel" og afsatte paa Kartet deri som "Klip als een Seyl".
Deres Beliggenhed er rigtigere paa det gamle hollandske
Kart end hos Scoresby. der lægger -Lodsbaaden"’ for langt
mod Syd og "Fyrtaarnet" for langt fra Land.
Guinea-Bugtens nordligste Pynt stikker, ifølge vore
Skitser, mere frem end paa Scoresby’s Kart. Heri stemme
vi bedre overens med "Zeespiegel".
Vogel-klip ligger ifølge "Zeespiegel" lige udenfor
Vestpynten af Syd-Bay. ikke som hos Scoresby i Sydvest for
denne. "Naar man ligger paa 15 Favne Vand i Syd-
hand, the long lagoon on the east side is not mentioned
in the earlier accounts of Jan Mayen, nor does it appear
on any of the annexed maps. In the "Zeespiegel," this
part of the coast exhibits two long bights. — Great Wood
Bay and Little Wood Bay ("Groote Hout bay" and "Cleyne
Hout bay"), disconnected by a rocky mass stretching
between them down to the sea. It is evidently this 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 Vogt’s work. In the "Zeespiegel,"
the bay has a flat sandy 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 summit of Mount
Esk. "towards the south-west the utmost extent ol the
island was visible;" but he does not say a word about 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 overlook the lagoon in its full extent,
and the same should be tin* case from the sftmmit of Mount
Esk. Hence, it would be reasonable to infer 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-barrier
stretching between it and the sea having been gradually thrown
up by the action of the surf, rather than, as Vogt
surmises, 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
connected 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
respectively 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
accompanying 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 better with the
"Zeespiegel."
Vogel-klip lies according to the "Zeespiegel" just
without the west point of South Bay, not as oli Scoresby’s
map to the south-west of that bight. "When anchored in
