Naval and Military Intelligence.

It was yesterday announced at Chatham that the
Government has given instructions to Major Pals
Hear, the inventor of the mode of strengthening cast
iron guns by the insertion of a wrought-iron tube,
to construct a 300-pounder gun on the plan pro-
posed by him, in order that it may be tested in the
usual manner at Shoeburyness, before any other
guns on the same principle are manufactured. The
advantages resulting from the discovery of Major
Palliser, of utilising the whole of the cast-iron
smooth-bore guns by supplying them with an inner
wrought.iron chamber, either rifled or of smooth
bore, is deemed of such wide importance that a care-
ful survey of the entire stock of smooth-bore ord-
nance, which has hitherto been deemed compara-
tively useless, has been made at Chatham, prepara-
tory, it is understood, to the most serviceable of the
guns now in store being treated according to the
proposed method. The invention depends upon the
now well understood fact that the inner portion of
a gun really does nearly all the work of resisting
the strain of the discharge. It follows that if
the brittle cast iron be removed from actual con•
tact with the exploding powder, and a wrought.
iron tube be substituted in its place, the gun
so compounded may be expected to prove as strong
as if it were altogether made of wrought iron, prop
vided always that the work transmitted by the tube
to the cast iron around it does not exceed the
strength of the material of which the tube itself is
composed. The truth of this theory has been de-
monstrated in a series of recent experiments made
by Major Palliser in the presence of the Ordnance
Select Committee. On the occasion of the first ex-
periment two old guns—one a 10-inch and the other
a 68• pounder—both treated on Major Palliser's
plan, were prepared and tested to destruction by
firing 100 rounds with service charges of powder
and cast iron cylinders, the weight of the whole
oharge being increased after every 10 rounds by the
addition of the weight of one more shot. In this
way the weight of the charge in the first 10 rounds
was 161 b. of powder and a 681 b. shot, and in the
50th to the 60th rounds 16lb. of powder and 3101 b.
of shot, In the last 10 rounds the charges had been
increased to 161 b. of powder and ten 68-pounders,
or 680Ib. of shot. The first of these guns was con-
verted into a 9-inch gun by the insertion of a
wrought iron tube, with this advantage, that it
could throw a round shot of 100 lb., instead of one
of 681 b., if required. The gun described went
through the ordeal most satisfactorily, and is the
only cast iron gun, whether strengthened or not,
which has endured so formidable a test, the con•
elusions drawn from the experiments being that both
68-pounders and 10-inch cast iron guns can be con-
verted into 100spounders—a species of weapon which
experience has demonstrated would be of the greatest
benefit as broadside guns. At the termination of the
first series of experiments the Ordnance Committee
directed the charges to be doubled, when the gun
finally gave way at the 7th round with a charge of
321 b. of powder and a shot of 2001 b. In this case, it
may be observed, the gun had already stood much
heavier strains, and only yielded at last to thegradual
process of wear and tear from such long continued
and excessive charges. The other gun tested was
an old worn out 10-inch cast iron gun, which had
already been condemned as unserviceable, but
which had been converted into a 61 inch by Major
Palliser, and rendered capable of throwing an elon-
gated bolt of 100 lb. weight. This gun was tested
in an exactly similar manner to the former, and
ultimately burst at the 81st round, with a cylinder
shot nearly Eft. in length, and weighirg 6121 b As
the usual service charge of a 32 pounder is 81b. of
powder and a 321 b. shot, the charge, therefore,
under which this gun succumbed was really equal
to Mb. of powder and rather more than 19 324
pounders of shot. Like its predecessor, this gun
showed greater Endurance than any previously
strengthened or unstrengthened cast iron gun. The
result was deemed so satisfactory that the Ordnance
Select Committee requested Major Palliser to make
a 7-inch gun rifled on the shunt principle. This
gun was accordingly constructed, the tube being
composed of different qualities of wrought iron
coiled, weighing about 16 cwt. At the trial of this
gun two rounds were fired with charges of 20Ib. of
powder and 1101 b. shot, and 20 rounds with 16-lb.
of powder ants 110Ib. shot, the shot used being
round headed Armstrongs. This trial was attended
with equally satisfactory results, the tube on being
taken out and examined being perfectly clean and
uninjured. The results of these trials prove most
clearly that the vast stock of cast iron guns now

lying comparatively useless at Chatham and else-
where, in consequence of the great expansion of the
modern principles of gunnery, may all be utilised
by their conversion into rifled guns by Major Pal-
liser's process, while a great mechanical advantage
is secured by the facility with which such guns can
be manufactured, and especially in the ease with
which the tubes can be bored and rifled.

RAILWAY INTELLIGENCE,

GREAT WESTERN.

The directors of this company have given notice
of an intended application to Parliament in the en.
suing Session for additional powers, to enable the
company to make a railway from the Stonehouse
and Nailsworth line to the Great Western Railway
at Stroud; also another line from Stonehouse to
Stroud, in the county of Glocester—a line from
Stonehouse to Kingatanley—a railway from the
Shrewsbuiy and Hereford Railway at Hereford,
near Barr's Court, to the Newport, Abergavenny,
and Hereford line at Holmer—a line from a point
117 i miles from London on the main line at Bristol
to a junction with the Bristol and South Wales
Railway at Barton Hil'—a junction line from the
company's main line at Acton, 41 miles from Lon-
don, to the North and South Western Junction
