From steam to electricity the transition is obvious. Punch notes the adoption of the "Electro-Magnetic Telegraph" by the Great Western Railway in the summer of 1844. In 1845 we read of an electric gun to fire 1,000 balls a minute. The laying of a submarine cable from Dover to Calais is discussed in 1846, but was not realized till five years afterwards, when Punch hailed the completion of the scheme as a new link between the two countries and celebrated it in a cartoon and a sonnet.
Already the influence of electricity on international relations had been foreshadowed, and in the same year in which Palmerston repudiated responsibility for the welcome of Kossuth in England Punch rudely described his message as "electric lying." The days of "wireless diplomacy" in the old sense of the epithet were passing, to the embarrassment of representatives who were within immediate hail of the central Government. Soon we begin to hear complaints of the new service on the score of delays and excessive charges, and when an earthquake shock was felt "for the first time" in Ireland in the winter of 1852, Punch notes that a writer in the Limerick Chronicle attributed it to the atmospheric influence of the electric telegraph! Electricity as an illuminant elicited an optimistic if somewhat previous eulogy in 1849; and cooking by electricity is foreshadowed in 1857. The laying of the transatlantic cable is welcomed long before it was an accomplished fact, but Punch's compliments had a sting in their tail when he wrote the following lines:—
AMERICAN JOURNALISM IN A NEW LINE
It is much to be hoped that the telegraph wire,
About to be laid down, will not form a lyre,
On which to strike discord 'twixt the old world and new;
Though scarce can we hope all its messages true,
For then t'other side would have nothing to do.
Punch's interest in aeronautics dates from his earliest infancy, though his mixture of prophecy and satire is rather confusing. Designs of aerial steamships abound in his columns; and one of them is not too bad an anticipation of the aeroplane.
