In
the evening there was a magnificent torchlight procession of the city
firemen.
That very day the cable breathed its last. Its insulation had been
failing for some days, and the only signals which could be read were
those given by the mirror galvanometer.[It is said to have broken down
while Newfoundland was vainly attempting to inform Valentia that it was
sending with THREE HUNDRED AND TWELVE CELLS!] The reaction at this news
was tremendous. Some writers even hinted that the line was a mere hoax,
and others pronounced it a stock exchange speculation. Sensible men
doubted whether the cable had ever 'spoken;' but in addition to the
royal despatch, items of daily news had passed through the wire; for
instance, the announcement of a collision between two ships, the Arabia
and the Europa, off Cape Race, Newfoundland, and an order from London,
countermanding the departure of a regiment in Canada for the seat of the
Indian Mutiny, which had come to an end.
Mr. Field was by no means daunted at the failure. He was even more eager
to renew the work, since he had come so near to success. But the public
had lost confidence in the scheme, and all his efforts to revive the
company were futile. It was not until 1864 that with the assistance of
Mr. Thomas (afterwards Lord) Brassey, and Mr. (now Sir) John Fender,
that he succeeded in raising the necessary capital. The Glass, Elliot,
and Gutta-Percha Companies were united to form the well-known Telegraph
Construction and Maintenance Company, which undertook to manufacture and
lay the new cable.
Much experience had been gained in the meanwhile. Long cables had been
submerged in the Mediterranean and the Red Sea. The Board of Trade
in 1859 had appointed a committee of experts, including Professor
Wheatstone, to investigate the whole subject, and the results were
published in a Blue-book. Profiting by these aids, an improved type of
cable was designed. The core consisted of a strand of seven very
pure copper wires weighing 300 lbs. a knot, coated with Chatterton's
compound, which is impervious to water, then covered with four layers of
gutta-percha alternating with four thin layers of the compound cementing
the whole, and bringing the weight of the insulator to 400 lbs. per
knot. This core was served with hemp saturated in a preservative
solution, and on the hemp as a padding were spirally wound eighteen
single wires of soft steel, each covered with fine strands of Manilla
