serve will consist of a line-of-battle ship, a frigate,
a corvette, sloop, despatch vessel, and six gunboats,
all to be equipped ready for the pendant when re-
quired. The other naval ports will possess a simi-
lar reserve. The Orlando, 50, and Speedy, 4, are

bably be prepared.
The Ariel, 7, screw, Commander Alexander, ar-
rived at Mahe, Seychelle Islands, on the 19th of
May, in company with her Majesty's ship Wasp, to
whose assistance she was despatched from Simon's
Bay, Cape of Good Hope, on the 18th of April.
The Lyra, 9, screw, Commander R. B. Oldfield, was
lying at Mahe on the Ariel and Wasp's arrival,
having brought in 200 slaves captured in an Arab
dhow near Zanzibar. The Lyra had recently taken
17 dhows, averaging 70 tons each. She would pro-
bably sail for England about the middle of June.
The Ariel and Wasp sailed in company from Mahe
for the Mauritius on the 30th of May.
A considerable number of Bertram's patent welded
beams have been landed during the last few days at
Deptford and Woolwich Dockyards, for fitment as
deck beams on board the various ships now building,
similar to those supplied to the Warrior, Black
Prince, Resistance, Defence, and other ships of the
same construction. It appears now to be the decided
opinion of most scientific men of iron shipbuilding
and engineering profession that most of the disasters
at sea and boiler explosions occur in consequence of
the inherent defectiveness of the rivetting system,
and the more so for ships, as the metal is more cut
away, to obtain the countersink for the rivet-head,
by which a smooth skin is obtained, thereby giving
speed to the vessel which could not be attained if the
heads projected outside. Another source of weakness
in the rivetting system is the attaching the water-
tight bulkheads to the side of the vessel, by a row
of rivet-holes, in a straight line, round the ship,
which perforation weakens the vessel in a similar
ratio to that of the separation on the postage stamp,
thereby showing the desirability of bringing out the
welding process, so that all sheet-iron structures,
whether of ships, steam boilers, &c., might be made
in one entire piece.
According to the official return recently published
