visited by more tourists and associ-
than any other bridge in the world.
Speaking Of long single spans re-
minds one that the longest in exis-
tence is to be found in the Tyrol. This
is the o Gorge, the single arch Of
masonry springing from bank to
the other to a distance of 1913 feet
above the level of the water.
me highest line in the world-the
oroya railroad of Peru-has some re-
markable bridges. This will hardly
be wondered at when it is remember
ed that the line traverses a series Of
mountains scanned with deep gullies
and torrential rivers. The traveller
VINO lands at Callao in order to reach
Oroya. 1873 miles inland, ascends 49,
sos feet in the course Of lO7 miles,
negotiating dozens of the canons and
rivers.
Five miles beyond Tamboraque the
line tunnels a peak. to emerge on the
brink OF a drop that falls sheer into
the river below. The gulf is spanned
by the Infernillo bridge, the name of
which. in view Of the savage sur
roundings and hair-raising leap that
the bridge makes across the void, is
sheer faces of the cliffs on either side
of h chasm the workmen had to be
suspended In cradles and loops that
dangled from ropes attached to
brackets driven in the solid rock
above.
The shoot from one tunnel mouth to
the other by an apparently frail link
OF steel is said to furnish a sensation.
Perhaps n Of the most pictures
que railroad bridges on this continent
Is to be found at Stony Creek. in the
Selkirk mountains. on the Canadian
Pacific railroad. There is a ''V'-shap-
ed ravine there Of great depth Ranked
by stern granite cliffs and crowned by
pine-clad hills. A noble arched steel
bridge springs from the sides Of the
gulch.
The Cisco cantilever bridge which
carries h railroad across the Fraser
river is also another striking illustra-
ton of the engineers skill. 1t leads
to a tunnel driven through the precipi-
O u wall OF the canon the boldness Of
the work being fttingly framed by
majestic surroundings.
British India has been called the

IT seems entitled to the distinction.
The Some bridge of the East Indian
railroad consists of 81 spans, giving
the structure a total length Of 1882
feet. thus making it one of the longest
bridges in the world. The Godavaria
bridge of h Madras northeast line
is s,066 feet in length and the Cox
te1k viaduct of Burma is 1925 feet
high.
1t was in Sweden that steel was first
used for the erection Of railroad
bridges. h innovation being started
by the late Major c. Adelskold in 1886.
His bridge was designed to carry the
uddevalla : Wenersborg .Herljunga
railroad across the Huvudnas Falls,
Just above the T%rollhatten Falls. At
this point the Gotta River forces its
just before it falls over a lofty ledge Of
rock. The design Of the bridge was of
a novel order. being somethink like
unto an inverted suspension bridge.
The Bergen-C hristiania line Of Nor
way ranks as one of the most striking
examples of railroad engineering in
Europe. h line was constructed
across a storm-swept plateau in one
OF the most sparsely populated dis
tricts in Europe, where the winter
lasts for eight or nine months. 1t
passes through 1874 tunnels and in
cludes IA bridges. ranging from a sim
%gle-span stone structure of so feet to
one of metal, 566 feet from end to
end.
In the little-known British colony
Nyasaland, in Central Africa, is a rail-
road bridge Of noteworthy construc-
ton. This is on the Shire river at
Chrome. 1t is about 420 feet in
length and has a lifting SPAN Of a
novel kind. Its construction is due to
the stipulation of the British govern
ment hat there should be no inter-
ference with the navigation of the
river. The bridge can be wound up''
by hand from the banks. The me-
chanism is Very simple and can be
handled by the natives.
China has many striking examples
Of railroad bridges. One over the
Lan-ho river is 2.17o feet in length,
with five spans Of 200 feet each. It
was designed by the late Sir Benjamin
Baker and aroused much criticism by
its unusual features.
