N. 2400.

This paddle steamer was built of iron at Hull, in 1861, by Messrs.
Samuelson, for the Atlantic Royal Mail Steam Navigation Co., popularly
known as the " Gal way Line."

Four similar vessels were originally constructed for this line, to carry
H.M. mails to Boston and New York, via Galway and St. John's, New-
foundland. Owing to accidents at sea and the inability of several of their
ships to realise contract speed, the company was voluntarily wound up in
1864.

The " Columbia" was fitted with eight watertight bulkheads, and had
the following principal dimensions : Tonnage (b.m.), 2,913 tons ; tonnage,
net register, ],625 tons; length, 360 ft.; breadth, 40 ft.; depth of hold,
32ft.

This brig-rigged iron steamer, built at Glasgow in 1862 for the Cunard
Co., was the last and finest paddle- driven vessel constructed for the Atlantic
service. She had seven watertight compartments, and a double bottom.
The masts were 30 in. diam.

The engines were of the side-lever type, with two cylinders 100 in. diam.
and 144 in. stroke and indicated 4,900 h.p. (see-No. 797). Steam at 20 Ib.
pressure was supplied by eight tubular boilers, and there were two funnels.
The diameter of the paddle-wheels was 40 ft., and the floats were 11*5 ft.
by 2 ft.

She had accommodation for 300 passengers, and stowed 1,800 tons of
coals.

In 1879, after having been sold to the Telegraph Construction and
Maintenance Co., she was converted into a twin-screw cable ship. On this
duty, and while at sea, in 1896, she sustained a severe explosion from the
ignition of vapour from a spirit paint, which blew out the bow and destroyed
the collision bulkhead, but the second bulkhead, 44 ft. from the stem,
resisted the inrush of water and saved the ship. In 1904 she was wrecked
at Guam, Ladrone Islands.

Displacement, 6,520 tons ; length, 366 -5 ft. ; breadth, 47 '5 ft. ; depth,
moulded, 32 ft.

a tubular boiler 9'5 ft. long by 13 ft. high, presenting 2,204 sq. ft. of
heating surface.

The screw was 11 ft. diam. by 22 ft. pitch, and was connected with the
engine shaft by a universal joint, so that it could be raised or lowered
without stopping the vessel. The average speed was 9 5 knots.

There were three masts, spreading sails of 1,418 sq. yds. area.

Load displacement, 1,461 tons ; tonnage (b.m.), 871 tons ; gross register,
