continued working extra hours, the demands on the depart•

Lord Warden frigate and the other vessels in hand having
very considerably diminished.
The favourable report made to the Lords of the Admiralty
of the working of the steam traction engines employed by
Messrs Aveling and Porter, in conveying the heavy portions
of the iron work for the dockyard, from the factory at
Strood to Chatham, have induced their Lordships to give
directions for one of the traction engines to be provided by
the patentees, and used in Chatham dockyard for one month,
during which time it will be employed in the heaviest kind
of labour, in order to enable the officials of the establish-
ment to report to the authorities as to its capabilities, and
the advantage or otherwise which wuuld result from the
general use of steam traction engines in the Govern-
ment dockyards. As an illustration of the enormous power
of these engines it may be mentioned that on Thursday
some of the officials of Chatham dockyard were invited
by Messrs Aveling and Porter to witness the working
of one of the traction engines just completed by them
for shipment to Australia to be used in conveying metal ore
from the mines to the seaport. The engine in question
started away from the factory with a train of waggons at-
tached, containing a cylinder of several tons weight, just
cast for the dockyard extension works, and upwards of 30
tons of coals, the gross weight of the whole being close
upon 40 tons. With this weight attached the engine tra-
versed the streets of Rochester and Chatham without occa-
sioning the slightest inconvenience to the ordinary traffic,
and fiaally ascended Star-hill, which has an incline of 1 in
12, at a speed of between 3 and 4 miles per hour, the same
hill being subsequently descended later in the day by the
same train with the greatest ease and safety. During the
time the engines have been employed in conveying materials
from Rochester to Chatham dockyard—a period extending
over several months—they have performed their allotted
tasks most satisfactorily, and not the slightest accident has
occurred, notwithstanding that the public streets have been
traversed by them at all hours of day and night.
As the result of the various successful experiments and
severe tests to which the new patent indented, small palmed
anchors, introduced by Capt. Rodger, R.N., have been re-
cently subjected at Woolwich, it was yester lay announced
that an Admiralty order had been received for the reception
and issue for service of a number of the anchors, weighing
respectively 40, 45, 50, 55, 60, 65, 70, and 75cwt. One of
Capt. Rodger's anchors, weighing 30cwt 2qrs 151 b, was yes-
terday shipped and tatted on board her Majesty's troopship
Fox, Staff-Commander T. Pullen, :to be used as a light
working bower anchor to supersede the old anchor, weigh-
ing upwards of 44cwt. The new anchor was tested on
Wednesday under the hydraulic press, in the presence of
Mr George Turner, the master shipwright of the yard, and
other officials, and by Captain Rodger's desire the strain
was worked up to the test of an anchor of double its
weight, viz.,-61cwt lqr 41b, the proof commencing at
Mons, lcwt 3qr 141 b, and gradually increasing to
the enormous drag of 49tons ocwt 2qr 141 b. Both
arms were subjected to the extreme trial, and on examina-
tion and measurement no signs of yielding were perceptible,
nor the slightest degree of permanent set, the dimensions
being precisely as Were the trial. On Thursday the anchor
underwent the usual fire test and smithery examination, and
was shipped and ordered on the following day for service
The metal was proved to be of undeniable quality. The
whole of Captain Rodger's anchors, according to the pre-
sent arrangement, are to be manufactured by the North
Field Iron and Steel Company, at Rotherham, in York.
shire, who are under a heavy bond to confine themselves
exclusively to that species of anchor, to avoid competition
or detriment to Captain Rodger's patent.
