en to rise up and rear
on end against the piers, but by the force of the current they were
speedily made to roll over into the stream, and in a moment after were
out of sight. For the two next days the river was still high, until on
the 4th April the waters seemed suddenly to give way, and by the
following day the river was flowing clear and smooth as a millpond,
nothing of winter remaining except the masses of bordage ice which were
strewn along the shores of the stream. On examination of the piers of
the bridge, it was found that they had admirably resisted the tremendous
pressure; and though the timber "cribwork" erected to facilitate the
placing of floating pontoons to form the dams, was found considerably
disturbed and in some places seriously damaged, the piers, with the
exception of one or two heavy stone blocks, which were still unfinished,
escaped uninjured. One heavy block of many tons' weight was carried to a
considerable distance, and must have been torn out of its place by sheer
force, as several of the broken fragments were found left in the pier.
The works in connection with the Victoria Bridge were begun on the 22nd
July, 1854, when the first stone was laid, and continued uninterruptedly
during a period of 5.5 years, until the 17th December, 1859, when the
bridge was finished and taken off the contractor's hands. It was
formally opened for traffic early in 1860; though Robert Stephenson did
not live to see its completion.
The tubular system was also applied by the same engineer, in a modified
form, in the two bridges across the Nile, near Damietta in Lower Egypt.
That near Benha contains eight spans or openings of 80 feet each, and two
centre spans, formed by one of the largest swing bridges ever
constructed,--the total length of the swing-beam being 157 feet,--a clear
water-way of 60 feet being provided on either side of the centre pier.
The only novelty in these bridges consisted in the road being carried
_upon_ the tubes instead of within them; their erection being carried out
in the usual manner, by means of workmen, materials, and plant sent out
from England.
During the later years of his life, Mr. Stephenson took considerable
interest in public affairs and in scientific investigations. In 1847 he
entered the House of Commons as member for Whitby; but he does not seem
to have been very devoted in his attendance, and only appeared on
divisions when there was a "whip" of the party to which h
