190 ENGINEERING WONDERS OF THE WORLD.
by a supreme effort and make his way to the
staircase, already blocked by a panic-stricken
crowd. Escape was cut off. Fortunately a
tremendous wave which bore him to the top of
the shaft enabled him to grasp the staircase,
and so effect his escape. Six of the workmen,
dragged by the wave back into the tunnel,
were drowned.
While Isambard was recovering from the
injuries sustained during this adventure, his
father resumed the duties of resident engineer.

bricked bed, repeated his former plan
up> and dumped down 4,500 tons of
clay and gravel. This work
exhausted the funds of the company. At a
meeting called on July 5, 1828, the Duke of
Wellington, who took a great interest in the
tunnel, appealed to the public to subscribe for
debentures which should enable the enterprise
to be carried through. As the necessary help
was not forthcoming, nothing remained but to
brick up the shield and wait for happier times.
The completion of this operation, early in
August, terminates the first period of the
tunnel’s history.
Though through no inherent fault Brunel’s
method had failed to accomplish the desired
end, the failure stimulated nearly five hundred

tunnel more cheaply and ex-
peditiously than would be possible if his
system were adhered to. Of these schemes
all but one were rejected by the directors,
and about this single exception the Duke
of Wellington made some scathing remarks.
The directors, nevertheless, looked so favour-
ably upon it that Brunel felt it to be neces-
sary to draw up a statement defending his
own principles, and setting forth in detail the
difficulties with which he had had to contend.

Money.
A commission appointed to sit in judgment
reported that the alternative plan was imprac-
ticable. This led to a resolution being passed
by the shareholders expressing confidence in
their engineer, and advising that an application
should be made to Government for the funds
necessary to carry on the work. Imagine the
indignation of the shareholders when they
learned subsequently that a loan had been
offered by the Government, but refused by
the management! Brunel’s patience now gave
out, and he resigned his appointment definitely
in disgust.
Popular opinion would not, however, allow
the tunnel scheme to fall through altogether.
It was thought that Government should give
the necessary aid. This en-
couraged the company to pre-
pare a petition to Parliament;
but, by some extraordinary
fatality, when the time came for its pre-
sentation the petition could not be found!
The Government consented, however, to ad-
vance £240,000 to the Tunnel Company, on
condition that the money “ should be solely
applied in carrying on the tunnel itself, and
that no advance should be applied to the de-
fraying any other expense, until that part of
the undertaking which is most hazardous shall
be secured.” This condition was unfortunate,
as it prevented the sinking of the second shaft
on the northern shore, and the simultaneous
prosecution of the work from both ends.
Brunel consented to associate himself again
with the enterprise. His first task was to re-
move the brick heading-wall and replace the
original shield—now in a ruin-
ous condition—by a new one
embodying certain improve-
ments. As a preliminary, the
space occupied by the shield had to be tim-
bered securely on all sides. This done, the
frames and other parts were removed in detail.
The new shield, built by Messrs. Rennie, was
