But it can readily be imagined that such a ponderous weight as this
carries a good deal of impetus with it, and since in most cases
the width of the water is confined, precautions have to be taken
to prevent the ship running ashore the other side and doing damage
to herself--perhaps smashing her rudder and propellers, or worse.
Therefore, heavy anchors have been buried deep into the ground, and
cables or hawsers are led from the bows and quarters and attached
thereto, or else to heavy-weights composed of coils of chain, whose
friction over the ground gradually stops the vessel. Not infrequently
the cables break through the sudden jerk which the great ship puts on
them, and the anchors tear up the slip-way. Perhaps as many as eight
cables may be thus employed, each being made fast to two or three
separate masses of about five to fifteen tons, but with slack chain
between so that only one at a time is started. As soon as the ship has
left the ways, all the cables become taut, and they put in motion the
first lot of drags. Further on, the next lot of drags receive their
strain, then the third, so that no serious jerk may have been given,
and the ship gradually brings up owing to the powerful friction. Lest
the force of the ship going into the water should damage the rudder or
the propeller, these, if they have been placed in position, are locked
so as to prevent free play. After this the ship is towed round to
another part of the yard where her engines are slung into her by means
of powerful cranes. The upper structures are completed, masts stepped
and an army of men work away to get her ready for her builders’ trials.
Carpenters are busy erecting her cabins, painters and decorators
enliven her internal appearance, and upholsterers add the final touches
of luxury to her saloons and lounges.

Turning now to the illustration facing page 290, we see the
Norddeutscher Lloyd _Berlin_ just before she was launched. The anchors
and cables which will be dropped as soon as she has floated will be
seen along her port side, and the platform for her christening is
already in place. In the illustration facing page 294, which shows the
launch of the Royal Mail Steam Packet Company’s _Araguaya_, we have
a good view afforded of the ship as she is just leaving the ways and
becoming water-borne. The other illustration on the same page shows the
launch of one of those turret-ships to which reference was made in an
earlier chapter. In the picture of the _Berlin_ will be seen the system
of arranging the steel plates in the construction of the ship, and the
rivets which hold them in place.
