Om Eftermiddagen loddedes 340 Favne udenfor Syd- ostkap. Kursen sattes nu nordover. Taagen begyndte at omhylle Beerenberg og vi saa dens Top og Skuldre for sidste Gang. I Nor dost for Nordostkap, 7 Kvartmil af, fandtes en Dybde af 1040 Favne. Dette giver en midlere Heldning af Havbunden udenfor Nordostkap af 8 Grader, hvilket. er noget brattere end Heldnipgen af Beerenbergs Basis henimod Nordostkap (efter Kartet 6.°6), men mindre brat end Heldningen mod Sydostkap (10°). Paa Skraanin- gen ned mod Nordostkap saaes en Eruptionskegle (Krater Sars), som Andes i teldre Tegninger, naar man ser noje efter, saaledes i Vogt’s Bejse og paa Lieutenant Bing’s Tegning Fig. 7. Paa Nordsiden af 0en saaes de 3 Is- brseer trsedende frem af dybe Dale foran den bratte, 60° heldende, 300 Meter hoje Fjeldvmg, Pig. 5. Hvad der laa hojere, var dmkket af Skylaget. Vi Ak saaledes desvaerre ikke 'se Beerenberg og dens Grundstykke fra Nordsiden, og de store Braeers Udspring fra Snegrsendsen gik ligeledes vor Iagttagelse forbi, da Taagen efterhaanden saenkede sig. Efter at have taget en Bsekke Lodskud i Nord og Nordvest for Jan Mayen, og fundet over 1000 Favnes Dyb . paa vort vestligste Punkt, livor Luftens Temperatur om Natten var kun lidt over Frysepunktet, men ingen Is Var at se, styredes tilbage mod 0ens Vestside. Da vi om For- middagen den 3die August nsermede os Mary Muss Bugten. var Vejret fremdeles nieget taaget. Vi styrede videre langs Landet sydvestover og spejdede opmerksoint efter en Lej- lighed til at komme i Land paa Sydlandet, men forgjaeves. Ofte tog Taagen Udsigten til Land ganske bort, og overalt saa vi Brsendingen paa Stranden lige sterk som da vi for- gjseves prpvede • at lande paa 0stsiden. Vi stoppede paa et Par 'Stationer og loddede — se Kartet — 98 og 156 Favne. Fra disse Stationer og fra Aere andre Punkter Ak vi gode Skitser af enkelte Partier af de lavere Dele af Sydlandet. Efter disse er saaledes Fig. 6 gjengivet, Man ser den regelmaessige Eruptionskegle. Hoyberg ude mod Stranden. Lsengere inde. ved Guinea Bugten, dukker et lidet,. men meget regelmaessigt kegleformigt Krater (Hosaaten) op af Lavlandet. Den lave Sydpynt vender lige mod Tilskueren. Bagenfof det foranliggende Lavland loiter sig med bratte Vaegge Sydlandets Hojfjeld. Oppe paa dette sees et kegle- formet Fjeld (Krater Voringen), et Krater efter al Sand- synligbed. De bratte Styrtninger mod Havet fortsaette lige til Cap Sydvest. Her er en, naturlig Port i Fjeldyt, gjennem hvilken Havet gaar. Udenfor Nesset sees de Syv Klipper med sine fantastiske Former. speed of the ship being read oA’ every Ave minutes on the scale of tbe water-log. At the beginning and tbe end of this interval, at a -given signal, one observer measured with the sextant the angle subtending between the bearing and the summit of the mountain, and another the height of the summit above the horizon. The result 'of the computation was 6380 feet. In the afternoon we sounded in 340 fathoms oA’ Cape South-East, and then steered northward. Clouds had now begun to gather round Beerenberg, and we had our last view of the stun ini t and upper part of the mountain. North- east of Cape North-East. 7 miles from land, the depth was 1040 fathom's. This shows a mean incline of tbe sea-bed off Cape North-East of 8 degrees, which slightly exceeds that of. the base of Mount Beerenberg towards'Cape North- East (according to the Map 6.°6), but is somewhat less than the slope towards Cape South-East (10°). On the north-eastern declivity was seen a parasitic cone(Sars’s crater), which may be found in earlier views of the island if care- fully looked for. for instance in a prospect in Vogt’s Tra- vels, and in one by Lieutenant Ring, Fig.. 7. On the north side of the island the 3 glaciers could be seen jutting out from deep valley's beyond the precipitous mountain-wall, which is here 90U feet high and shelves at an angle of 60°, Fig. 5. Whatever lay at a greater elevation was wrapped in clouds. Unfortunately, therefore, we got no view of Mount Beeren- berg from tbe north side of the island, and the origin of the glaciers at the snow-limit likewise escaped our obser- vation, the fog having gradually descended. After having taken a series of soundings to the north and north-west of Jan Mayen, and found a depth of more than a thousand fathoms at the most westerly station, where the temperature of the atmosphere at night was only a little above the freezing-point, tholigh no ice was to be seen, we steamed back to the west side of the island. In tbe forenoon of August the 3rd,. when bearing down on Mary Muss Bay, the weather was exceedingly foggy. We steered thence in a south-westerly direction along the coast, carefully watching for an opportunity to land, — but in vain. The fog frequently shut out the land; and a line of break- ers was everywhere observed along the shore, tbe ■ swell being no less heavy than on the occasion of our unsuccess- full attempt to land on the east side of the island. We stopped twice and sounded (see Map) in 98 and 156 fathoms. At these stations and several other points we succeeded in sketching the scenery of the low-lying tract in the southern part of Jan Mayen. Fig. 6 is from these sketches. Near the shore we see' the parasitic •crater Hoy- berg; and farther inland, in the vicinity of Guinea Bay, a conical crater, — the -hay-cock." — small but regular in form, rises from tbe low-lying, tract around it. The Low South Point projects in a line with the point of view. Behind the low tract in the foreground of the engraving, towers with its precipitous walls the plateau of the south- ern part of Jan Mayen. Here may be seen a conical- shaped mount (the Voringen crater), in all probability of
