Albert Franklin Matthews tells an
interesting story Of THE Evolution
OF a Battleship" IN the July number
of the Century. This Is 4 history of
the construction Of tho Indiana. SO
far the only vessel Of this class we
have In our navy After describing
the wonderful power Of this mon-
ster, the most formidable engine of
war. In the world, and the manner Of
its construction, Mr.. Matthews said:
$50 the building goes on until the
launching day CONFESS and two broad
ways are built up against the bottom
of the vessel, and the keel blocks on
which 1t has been resting are knocked
away. In the launch OF the Indiana
Mr.. Nixon ran row Off electric
lights beneath the bottom OF the yes.
sci, adding another innovation to the
details of American shlpbui.dlng.
Each launching way consists Of upper
and lower planking, between which
.is.spread thousands OF pounds Of the
best tallow. At the bowof the boat
these upper and lower planks are
clamped together, aud when all is
ready they are sawed apart, and the
vessel starts The upper part of the
ways slides into the water, with the
vessel, and the lower part with the
smoking hot tallow remains station
airy. w
+ "A launch in these days Is so
smooth, and so soon ended, rarely

from start to finish, that'one scarce
recognizes It's difficulty. Three things
are absolutely necessary: 1t must be no
time, when the tidal water is high
est; it must be of smart speed. so as
not to stick on its downward journey
to the water. and 1t must be accom-
plished without straining. So COM
pick thing is launch that the
careful engineer in charge Is able to
estimate the strain on every part Of
the vessel for every position 1t occu-
pies, at intervals of one foot, on its
way down the incline.
There is one supreme moment. 1t
is when the vessel is nearly two
thirds in the water. The buoyancy
of the water raises the vessel and
throws its weight on its shoulders.
Here is where the greatest danger Of
straining comes. and should the
ways break down the vessel would be
ruined, matter OF nearly 1000, 900
in ship like the Indiana when it
was launched.
"The launch over, the machinery
Is lifted In and fitted, and then comes
the board of Government experts,
who look the vessel over inch by inch,
the fires are started, and the trial
trip follows. For four hours, amid
suppressed excitement that answers
nervously to every CULVER Of the YES
sci, the engines are run at full speed.
A premium or a penalty Is at stake
now. The breakage Of a bolt or the
disarrangement Of valve may mean
thousands of dollars of loss to the
contractors. Trained workmen are
locked in the fire rooms, not to be
released until the test Is over Cooled
drinking water, with oatmeal
sprinkled UPON it, Is run down to
them in a rubber tube from barrel
on deck. A hose is played on the
costly machinery in places where
there is danger from overheating, as
though it were on fire. Almost every
pound of coal used on the trip is care
fully selected.
"When the. four hours are passed
and the strain is over sigh of relief
from every one on board, and even
from the vessel herself, goes up. and
the ship passes from the contractor
to the Government, and day after
day while she is in commission the
flag will be saluted, and the score or
more of other ceremonies and for
malities observed on a man-of-war
will follow"
