subsequently transpired that a Boulogne fisherman had hooked up the line
with his trawl, "mistaking it for a new kind of seaweed!" This
enterprise excited little attention at the time. It was, in fact,
regarded as a "mad freak" and even as a "gigantic swindle." When
accomplished, The Times remarked, in the words of Shakespeare, "The jest
of yesterday has become the fact of to-day"; and a few hours later it
might with equal truth have been said that "the fact of yesterday has
become the jest of to-day!" The feasibility of laying such a line and of
transmitting electric signals across the Channel had, however, been
proved. The signals obtained had, moreover, the effect of eradicating
the then very prevalent belief that, even if the line were successfully
submerged, the current would become dissipated in the water.[6] It now
remained to find a satisfactory method of protecting the insulated
conductor from injury during and after laying. The excellence of the
insulating material was recently testified to when some portions were
recovered.
Though the above line was not, practically speaking, turned to any
account, it was by no means abortive, for the signals it had conveyed
were sufficient to "save the concession," which was renewed by the
French Government on December 19, 1850. But the previous failure had
made capitalists distrustful; and only some weeks before the expiration
of the time limit the necessary funds had not been raised.
_Dover-Calais, 1850-'51._--The undertaking was saved by the energy and
talent of one man, Mr. T. R. Crampton, an eminent railway engineer. He
raised the necessary capital (£15,000), putting his own name down for
half this amount and being joined by Lord de Mauley and the late Sir
James Carmichael. He (Mr. Crampton) also settled the type of cable to be
laid--based on the iron pit-rope; this, in one form or another,
practically remains the type of to-day. The cable contained four copper
conducting-wires of No. 16 B.W.G., each one covered with two layers of
gutta-percha to No. 1 gage; these four insulated conductors, or "cores,"
were laid together and the interstices filled up with strands of tarred
Russian hemp. The outer covering consisted of ten galvanized-iron wires
of No. 1 gage wound spirally round the bundle of cores; this armor was
provided "with a view to protecting the insulated conductors from the
strains and chafing which had so seriously interfered with the chances
of the previous line." The completed cable weighed about seven tons to
the mile. It was coiled into the hold of an old pontoon hulk, which was
then taken in tow by two steamers. A third tug to stand by, and a small
man-of-war steamer to act as pilot, accompanied the laying expedition.
The cable was landed at the foot of the South Foreland lighthouse and
paid out toward Cape Sangatte, but the weather was less favorable than
on the previous occasion; moreover, the weight of the cable--in the
