IN 1856, an Englishman who had recently invented a rotating projectile was witnessing guntrials with it on a French artillery practice ground near Paris. At that time, both gun and projectile were made of cast iron. These trials were a failure because of the frequency with which the gun burst, and the French commandant, who was in charge, said to him: “This invention of yours will require a better gun than one made of cast iron.” So Henry Bessemer, for it was he, returned to England to make a gun tube that would not burst on firing.
