PREFATORY NOTE
THE jubilee of Submarine Telegraphy having lately been achieved, and that connected with the Atlantic cable being somewhat close at hand, it has been thought a suitable moment for the appearance of this little volume.
In these days when the substitution of submarine cables by wireless telegraphy systems is a subject of common talk, it may be well to pause for a moment and contemplate the period of time covered by the gradual evolution of old and existing methods which at length achieved the result we now enjoy—a practical commercial telegraphic system between all the nations of the world, and notably between the United Kingdom and America.
By a somewhat curious coincidence the engineer of the first Atlantic cable accomplished his achievement at practically the same youthful age (twenty-six) as Mr. Marconi when first transmitting signals across the Atlantic without any intervening wires.
