THE LAYING OF SUBMARINE CABLES.
365
The Faraday is a ship of
very similar dimensions. This
vessel is of interest in that,
penny steamboat-like, she has
bows (in addition to rudders)
aft as well as forward, the
idea being to facilitate cable
operations.
Amongst smaller represen-
tative vessels we have
H.M.T.S. Iris, the guardian
of the All - British Pacific
Cable, with a gross registered
tonnage a little over a
quarter that of the Colonia.
But though one of the
smallest, the most interesting
telegraph ship now is the
Telconia, just recently built
for the Telegraph Construc-
tion Company. She, in fact,
forms the first cable-repairing
vessel so. designed that every-
thing is ready to hand in its
proper place, all the gear re-
quired for cable operations
being forward, and the sailors’
quarters relegated to the
stern.*
Fig. 14 presents a general
idea of the disposal of the line, as well as
the machinery for handling it, on a vessel
intended for telegraph work.
This view happens to depict
the Great Eastern with her
historic cable cargo ; but the
same general plan is equally
applicable to modern custom.
The line having been made at the factory,

The cable is drawn out from the factory tanks

over tackle leading to the laying vessel,*
into corresponding watertight iron tanks on
board—of which there may be three or four
for different types and sections of cable,
apportioned in suitable positions ready for
laying.
Fig. 15 illustrates one of these tanks, with
the cable partially coiled therein—indeed,
very closely packed in horizontal flakes, each
carefully whitewashed to prevent sticking.
Obviously no form of cable could be coiled
to the very centre of the tank : the space is
therefore usually filled up by a system of
