Albert Franklin Mat.,.e.Ys tells an
interesting story of 'rhe Evolution Of
Battleship," in the Century. This is
a history of the construction of the In.
diana, so far the only vessel of this
class we have in our navy. After de-
scribing the wonderful power of this
monster, the most formidable engine
of war in the world, and the manner
of its construction, Mr.. Matthews says:
So the building goes on until the
launching day comes, and two broad
ways are built up against the bottom
of the vessel, and the keel-blocks on
which it has been resting are knocked
away. In the launch of the Indiana
Mr.. Nixon ran a row of electric lights
beneath the bottom of the vessel, add
ing another innovation to the details
of American ship-building. Each
launching way consists of upper and
lower planl1ing, between which is
spread thousands Of pounds of the best
tallow. At the bow of the boat these
upper and lower planks are clamped
together, and 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 low
er part with the smoking hot tallow
remains stationary.
A launch in these days is so smooth,
and so soon ended, rarely occupying
more than twelve seconds from start to
finish, that ono scarcely realizes its
difficulties. Three things are absolute.
ly necessary; it must be on time, when
the tidal water is highest; it must
be of smart speed so as not to stick on
its downward journey to the water;
and it must be accomplished without
straining. So complex n thing is
launch that the careful engiueer-in,
charge is able to estimate the strain
on every part of the vessel for every
position it occupies, 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 two million dollars in q 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 fol
lows. For four hours, amid suppressed
excitement that answers ncrvously to
every culver of the vessel, the engines
are run at full speed. A premium Or
penalty is Mt stake now. The breakagc
of bolt or the disarrangement of
valve may mean thousands of dollars
of loss to the contractors. Trained
workmen arc locked in the firerooms.
