stillet i Fig. 2 og Indredning under Læ i Fig. 3.
Agten-for Fokkemasten stod en almindelig Dampie inch (Fig. 2 v\
der ved Hjælp af en Kjettingkabellaring kunde benyttes til
Ankerhivning. Forrenfor Hytten om Styrbord var opslaaet
a f Planker en Binge (b) med 2 Afdelinger, der tilsammen
rummede indtil 6000 Favne Skrabetoug, og i denne laa
Tou-get klart og luftigt. Paa Fordækket var ligeledes i 1877
og 1878 anbragt 4 Falconetter, der med Rapperter og
andet Tilbehør velvillig blev udlaant til Expeditionen fra
Bergens Værft.

Paa Hytten var anbragt en af Skibets Baade om
Styrbord og udenfor denne hang i Daviderne en Skjækte. Om
Bagbord stod Expeditionens store Livbaad, S.^ö (27 Fod)
lang. 2.m3 (7. Fod) bred og l.m3 (4 Fod) høj i Stevnene.
Midskibs i Forkant stod Stativet med Balancebordet til
Fox-Oirkelen (f) og agtenfor Skylightet til Spisesalonen (s)
stod Standardkompasset. (c) og Styreapparatet (r). Rathjulet
bevægede med Drev den lavere liggende Ratstamme, og i
Tandkronen om denne laa Bugten af Kjettingen, der gik
gjennem almindelige Skildpadder først ud i Borde, derefter
langs Hyttetaget, saa ned paa Agterdækket og agterover
langs dette, og endelig gjennem Skildpadder i Borde agterud
og paa Rorpinden, der viste agterover. Paa Grund af
denne lange Ledning virkede Apparatet langsomt. I 1876
var Kjettingen smekrere og virkede agterud med dobbelt
Part paa Rorpinden, i hvis Ende der var tilsvarende Blokke.
Den blev let slak øg var tilbøjelig til at komme i Uorden.
I 1877 anbragtes en sværere Kjetting, der virkede direkte
paa Rorpinden, hvorved de nævnte Ulemper hævedes. Det
blev aldrig nødvendigt at ty til Varerattet agter (q). Lige
agtenfor Styreapparatet blev i 1877 opsat et Bestikhus (h).
Paa begge Sider af Hyttedækket og i Agterkant af samme
var udbygget Loddebroer 3.’"1 (10 Fod) lange og l.m9 (6 Fod)
brede (Fig. 2, l, Fig. 14 og 21), forsynede med
Jernræk-verk og støttede med Stræbere mod Skibssiden. I
Agterkant af Hytten og paa begge Sider af midtskibs var
anbragt "antifriction" Fodblokke (Fig. 2 a, Fig. 14 og 21),
der vare hukede i lange Øjebolte, som løb ned langs
Agterkanten af Hytten og gjennem Dæksbjelken.

Paa Agterdækket strax agtenfor Stormasten stod
Ind-hivningsmciskinen (Fig. 2 i og Fig. 5). Den var leveret
fra Nylands mekaniske Verksted i Christiania. Den
dobbelte vertikalt staaende Højtryksinaskine paa 8 Hestes Kraft
drev rundt en under samme langskibs liggende Axel, der
forrenfor og agtenfor Krumtapperne var forsynet med to
Skruer uden Ende. Disse greb i Tandhjul (Diameter 0.’"47
rz 1 Fod 6 Tom), der havde svære horizontalt og
tver-skibs liggende Axler, 2.’"37 (7 Fod 61/2 Tom.) lange, og
paa Nokkerne af disse udenfor Lagerne i Ramverket var
Tapperne indsmøgede og fæstede med Kiler. Tapperne
om Styrbord, der brugtes til Indhivningen af Skrabetouget.

Fig. 2 represents the roof and Fig. 3 the interior fittings.
Abaft the foremast was a Steam-ivinch (Fig. 2 v), which,
when connected with a chain-messenger, would serve for
heaving the anchor. In front of the roundhouse, on the
starboard side, had been fitted up a spacious and
well-ventilated Locker (b), with two compartments, affording room
for stowing away 6000 fathoms of Dredge-rope, ready for
immediate use. On the forecastle had been mounted, for
the cruises in 1877 and 1878, 4 howitzers, kindly lent to
the Expedition, along with the carriages &c.,. from the
Royal Dockyard at Bergen.

The roof of the roundhouse, on the starboard side,
supported one of the ship’s Boats, alongside of which,
suspended on davits, hung a small skiff. On the port side was
placed the lifeboat of the Expedition, 28 feet long, 7 feet
beam, and 4 feet deep in the stems. In the forepart,
amidships, stood the foot of the balance-board for the
Fox-circle (/), and abaft the mess-room skylight (s) were the
Standard-compass (c) and the Steering-apparatus (r). By
means of cogwheels, the motion of the steering wheel was
transmitted to the barrel; and round the latter, over a
toothed wheel, lay the bight of the chain, which, on being
rove through cheek-blocks in the ship’s side, was carried
along the roof of the roundhouse down along the after-deck,
and then, through cheek-blocks in the ship’s side, right aft
on to the tiller. With so long a lead, the working of the
apparatus proved somewhat slow. On the first cruise, in
1876, the chain had been of smaller size, and rove double
on the tiller, through corresponding blocks at the end;
hence it easily got slack, and was apt to kink. In 1877,
therefore, we substituted a stouter chain, which led singly to
the tiller, and were thus able to remedy the defect.
On no occasion had we, however, been compelled to have
recourse to the spare wheel aft (q). Immediately abaft
the steering-apparatus, was a small deck-house (h). put
up in 1877, containing the log-slate, charts, &c. From
both sides of the roof of the roundhouse, and from its
after extremity, projected Sounding-bridges, 10 feet long by
6 feet wide (Fig. 21 and Figs. 14, 21), with an iron
railing, and supported by stays against the ship’s side. At
the after end, and on both sides, of the roundhouse, there
were antifriction Blocks (Fig. 2 a, and Figs. 14 and 21),
hooked to long eye-bolts extending down along the
after-bulkhead of the roundhouse and thence through the nearest
deck-beam.

On the After-deck, immediately abaft the mainmast,
was placed the the Donkey-engine for hoisting the dredging
and sounding gear (Figs. 2 i and 5), made at the
Nyland Works, Christiania. This double-cylinder, high-pressure,
vertical engine, of eight horse-power nominal, imparted a
rotary motion to a shaft extending fore and aft beneath
it, and provided with a pair of endless screws, one before
and one behind the cranks. These screws bit into
cogwheels (diameter 1 foot 6inches), fixed on stout
horizontal shafts, 7 feet 91/* inches long, lying athwartships;
and to the ends of these shafts, which projected beyond the
bearings on the frame, were fixed the drums, firmly secured
