374 ENGINEERING WONDERS- OF THE WORLD.
■testing and signalling had been considerably
improved since the laying of the first cable.
Yet, notwithstanding the dimensions of the
core, these new lines only worked at first at
a rate of eight words per minute. This
speed was, however, increased later on up to
fifteen words per minute by the application
of condensers in the receiving circuit at
each end.
Unfortunately, both cables broke down a
few months after they were laid, and one of
them again during the following year. The
faults were localized with great accuracy by
Mr. F. Lambert on behalf of Messrs. Bright
and Clark, as engineers to the “ Anglo-
American ” Company ; and, not having been
killed electrically like that of 1858, these
cables were in due course repaired, afterwards
doing good work for several years.
On the return of the 1866 expedition a
banquet was given to those concerned in the
undertaking, and speeches suited to the
occasion were made by Sir Charles Bright,
M.P., in responding as one of the original
projectors, and as engineer to the various
enterprises, as well as by the American consul,
on behalf of Mr. Cyrus Field ; but the re-
maining projector, Mr. J. W. Brett, had died
in the interval.
Appropriate honours were subsequently be-
stowed on those immediately associated with
these further undertakings, which left their
results behind in complete and lasting form.
Other transatlantic cables have since been
laid from time to time, and there are now
as many as sixteen in all. Several of these
are controlled by the same companies, whilst
those connecting the American continent with
France and Germany are owned by foreign
interests.
