EEKLY HAWK-EYE
Recent events have snphaticaliy su.
d taine6 the soundness Of the hrinciples Ion
: since laid down by naval officers, both j
TINS country and Europe, that speed an
weight OF armament are EQUALLY as esser
tial az invulnerability, which the Englis
experiments at Shoebnryness and our ow
experience in the attack on Fort Sumte
have inny proved is practically unattains
Die, a. least against l5-inch guns, and th
; armstrong 60O-pounders. 10 meet bot
tnese requirements has been Mr.. Webb
j pn1ect IN laying down the plans for tn
Dundefberg, to which an extreme lengt
OF 81 feet and width Of "a feet give . dis
placement Of over 900 tuns, a fleating pow
i er which, when loaded with engines, boil
eas, - neavy guns, 900 tuns Of coal, 100
.uns OF armor plates, and in full fghtinI
trim, will still leave the Dunderburg on
Of the most buoyant vessels In the NAVY.
while taking due care that the Dunder
Derg should be safe in Q heavy sea and re-
elstless 20 attack, Mr.. Webb has by NJ
means lost sight Of the necessity Of of1erinf
me utmost resistance to hostile shot anS
snell; FOR this end Mr.. Webb has com.
Dlne0 tne advantages offered by presenting
an angular surface to an enemy's Ere With
me protective powers Of ~ inch solid ar.
NOR plates. the sides Of the upper OF
lighting deck make the angle Of about q
degrees with the perpendicular, and meet
the hull, which slopes upward and out
ward, at an obtuse angle Of about 100 de-
Gent to throw or the shot, which win have
no opportunity Of striking point blank.
As stated before, the extreme length Of
tne Dunderberg is 377 feet. and her ex.
trenne width Il feet, but this includes about
~ ieet OF overhang at the stern to protect
the rudder and propeller, and solid ram
projecting 40 feet from the stem under the
The extreme length Of deck is 354 feet. Of
which more than two-thirds il occupied by
the nghting deck, seven feet high. On the
top OF this fighting deck are two turrets
and the smoke-stack, each Of the turrets
mounting two l5-inch guns, and each tur-
high. -.......s.,.,-.7 - 80
The turrets win be u inches il thickness.
and the fighting deck will be coveredsvith
solid plates OF the same thickness as the
hull, and which have been proved to be at
least ~ per cent, stronger than an equal
thickness Of metal made up, a. in the case
of the monitors, Of five a-inch Sheets
These plates have > backing of no less
thick ness than i've feet of white pine logs,
but which tapers to 80 inches at six feet be.
low the load line, while the engines are not
only AZ usual placed below the water.line,
but also have the additional protection OF
the coal bunkers on each side, extending
the whole length and hight Of the ship, and
which will hold over Zoo tuns.
The boilers are six in number, and work
two engines with lO0-inch cylinders and
! 200 nominal horse power. The diameter
of the screw will be q feet and the length |
Of the screw shaft los feet; while decided
novelty in steering apparatus, in the shape |
Of ANAL! auxiliary rndder, is placed for
ward of the screw, In addition to the large |
and main one occupying the usual position
great additional liveliness in steering, are |
expected from this arrangement, and it il |
hoped that the unwieldinees which inter- |
feres 20 much with the steering of all fat |
bottom boats without. keels, viii thus BE-
overcome.
Ali the internal fittings are Of the most
massive character and Of the greatest
strength, thedeck planks being nine inches |
thick, and the beams Of the engine-bed are
Of extraordinary size and thickness, and |
profoundly impress the heholder with the
sOlidity and substantial character Of the I
displayed throughout. OF

The number Of Armor plates il 500, each /
weighing two tuns, 50 that the total weight |
If armor will be just 900 tuns, more than

It the Etna Iron Works, while the cost OF

Mr.. Webb is constantly suggesting some
'ctual cost will probably considerably ex.

Such il the imperfect description which

,ermits Of the most important experiment
q naval architecture that has been made
q this country, and We sincerely hope that
win prove successful. Whatever form
