between Donaghadee (Ireland) and Port Patrick (Scotland),
across the Irish channel. This cable was of the same size and

serviceable for telegraphic purposes. This cable was manufactured in the short space of twenty-four days by Messrs.
Newall & Co. The cost of it was about ~13,000. It was
laid for the Magnetic Telegraph Company. Another cable of
the same make was'lalit across %he NianniA At Athn % saim' phXlbi
