Jevn og forøvrigt af lignende Konstruktion som
L’oddeblok-ken. Skiven, der var solid, havde en Diameter at 0m.521
(1 Fod 8 Tomnier). en Tykkelse af 0m.15 (5-’/: Tomme), og
Furens Dybde var 0m.079 (3 Tommer).
Skrabeaccuniula-toren hang paa Styrbord Side. i et Topreb. hvis øvre Ende
var fastgjort til Stormasten over Godset. Fig. 14 viser
Accumulatoren hængende i Styrbords Vant, hvor den havde
sin Plads, naar den ikke benyttedes til Skrabning.

Skraben eller Trawlen gjordes klar paa Agterdækket
mellem Nedgangskappen til Lugarérne og Kappen ved
Siden af Dækrullen (Fig. 1. Fig. 2. Fig. 14). Skrabetouget,
der laa i sine Binger (Fig. 2. b) agtenfor Fokkemasten,
og soiu i Tampen havde Kous og Hex. toges gjennem en
Kasteblok paa Fokkemasten (se 1 ig. 20), derfra over Hytten
og gjennem Kasteblokken i Accumulatoren, og hexedes i
Hanefoden til Skraben eller Trawlen. Paa Skrabetouget
var indsmøget en Pukkenholts Dor eller Kous med en lang
Stjert. Dens Plads var mellem Skrabeblokken og Skraben
(Trawlen). Accumulatoren udhaltes meel firskaaren Talje
(Fig. 14) paa Plads under Styrbords Storraanok. Raaen
brasedes saaledes, at Accumulatoren haug omtrent midt ud
for Loddebroen. (lig. 1. Fig. 20). Da der ved
Skrabnin-gen kunde gaa stor Kraft paa Raaen saavel nedad som
indad, var den paa Styrbord Side faststøttet. foruden ved
Toplent. Rakke og Braser, ogsaa ved en Talje som
Extra-Toplent og en Støttalje paa Bagbord Side, som "Fig. 14
viser.

Manøvrerne ved Bu udskrabning var ikke meget
forskjellige. enten man brugte Skrabe eller Trawl. For
Tydeligheds Skyld skal de her særskilt beskrives, forsaavidt
nødvendigt er.

Bundskrabning med Skrabe. — Skibet sattes med fuld
Fart op mod Vinden med denne lidt ind om Styrbord.
Naar det var k,ommet i godt Sig, standsedes Maskinen,
Skraben løftedes ud over Rækken med Haandmagt og
kastedes i Vandet. Forud ved Fokkemasten stod en Mand.
meel Læderhandsker paa Hænderne, færdig til at fire ud
paa Skrabetouget. assisteret af- en anden Mand. der ved
Hjælp af en Haandspage holdt Touget klart til at løbe fra
Kvejlen i Bingen. Strax Skraben var i Vandet,
kommanderedes: -’Fir"! og iuan firede langsomt paa Skrabetouget,
saa man kunde se, om alting var klart. Naar Skraben var
agtenfor Skruen, sattes denne atter igang til 4 Knobs Fart,
som Maskinisten holdt jevn ved at observere Vandloggen.
(Se nedenfor). Man firede nu, med jevnlige Anhold, for at
holde Touget og Apparatet strakt, stadig under samme
Kurs. som da Skraben kastedes overbord. Naar 200, 300
eller 400 Favne, efter den mindre eller større Dybde, var
udfirede, standsedes atter, Touget haledes ved Hjælp af
Kousen og Stjerten ind til Hakkebrættet, og der paasattes
en Trætærs ved Hjælp af Skibmandsgarnsurring, agtenfor
Kousen. Der sattes atter i Gang med sannne Kurs og
Fart. og man sejlede ud den liele Touglængde. der ansaaes
fornøden, nemlig mindst det dobbelte af Dybden og for
mindre Dybder mere.

struction to the sounding-block. The sheaf, which was
solid, had a diameter of 1 foot 8inches and a thickness
of 0 inches; the depth of the groove was 3 inches. The
accumulator used for the dredge hung — on the starboard
side - in a pendant, the upper end of which was secured to
the mainmast above the rigging. Fig. 14 represents this
accumulator as it hung suspended in the starboard shrouds
when not in use.

The dredge and the trawl were got ready on the
after-deck, between the companion-hatchway to the
cabins and the hatchway alongside of the reel (Figs.
1. 2. and 14). The dredge-rope, which at one end had a
thimble and shackle, was rove from the lockers (Fig 2 b)
in which it lay coiled abaft the fore-mast, through a
snatch-block on the mast (Fig. 20), carried from thence over the
roof of the roundhouse and through the snatch-block of the
accumulator, and then shackled to the crow-foot ot the
dredge or trawl. Between the dredgiilg-block and the
dredge (or trawl) a thimble of lignum vitæ, with a lizard,
was slipped on to the dredge-rope. The accumulator was
triced up under the starboard main yard-arm by means of
a guntackle purchase, the yard being trimmed so as to
bring the accumulator nearly abreast, of the sounding-bridge
(Figs. 1 and 20). As the strain, inwards as well as
downwards. to which ille yard was exposed when dredging,
might be very considerable, it was secured, not only
by braces, lifts, and trusses, but also, on the starboard
side, by a purchase, as a preventer-lift, and on the port side,
by a rolling-tackle, as shown in Fig. 14.

Dredging and Trawling from the " Varingen"
Botli operations were conducted very much alike. We
shall, however, for the sake of perspicuity, describe our
mode of working each of the two instruments.

Working the Dredge. — We steamed full speed ahead,
with the wind a little on our starboard bow. So soon as
the vessel had got sufficient headway, the engine was
stopped, the dredge lilted by hand over the railing and
dropped into the ,sea. At the foremast, a man with thick
leather gloves stood ready to pay out the dredge-rope,
which another kept clear with a handspike as it ran out
from the coil in the locker On the dredge entering the
water, the word was immediately given to veer, when the
paying out commenced, — slowly, however, to make sure
that all was right. So soon as the dredge was clear of the
propeller, the vessel again went ahead, steaming at a uniform
rate of 4 knots, which the engineer was enabled to keep
up by frequent reference to the water-log (see below).
Meanwhile, we kept steadily veering, while taking care, by
frequent holding on to the rope, that the length run out
should be properly taut, and steering the course given to
the ship when the dredge was put over. After paying out,
according to depth, 200, 300, or 400 fathoms, we again
stopped, hauled in the rope to the tatfrail by means of the
lizard and thimble, and fastened, below the latter, with
spun-yarn, a wooden toggle to the rope. Starting again
(same course and speed), we next ran out the whole
length of rope deemed necessary for the operation. —
