Cotton, having largely contributed to our national prosperity in times of peace, promised, not long since, to play a very important part in the strategies of war; and this by its use in place of gunpowder; wherefore the new substance was termed "Gun-cotton." The merit of the invention is believed to be due to Professor Schonbein, of Basle. In 1840, the novelty was first announced as an explosive compound, possessing many apparent advantages over gunpowder. It was described as a cotton prepared by a secret process; Professor Schonbein made an interesting experiment upon the wall of an old castle: it had been calculated that from three to four pounds of gunpowder would be requisite to destroy this wall, and a hole capable of containing that quantity was prepared. In this aperture were put four ounces of the prepared cotton, which, when fired, blew the massive wall to pieces. Again, the sixteenth part of an ounce of the prepared cotton, placed in a gun, carried a ball with such force, that it perforated two planks at the distance of twenty-eight paces; and, at another time, with the same charge, drove a bullet into a wall, to the depth of three inches and three-quarters. Professor Schonbein attended the meeting of the British Association for the Advancement of Science, held at Southampton, in 1846, when the operation of this new power was explained and experimented with. Subsequently, the professor attended at Osborne House, to exhibit the properties of his gun-cotton to Prince Albert, when Schonbein offered to explode a |
