If pure chemicals are employed in the manufacture, and the gun-cotton and nitro-glycerine be made of the highest nitration and best quality, we have a smokeless powder which will possess the following desirable qualities: 1st. It is absolutely smokeless, that is, its products of combustion are entirely gaseous. 2d. Its products of combustion are in no way deleterious or unpleasant. 3d.
He carried no umbrella, preferring to stand up and fight it out with the storm face to face, and because he detested a contemptible sneaking subterfuge of an umbrella, pretending to keep him dry, and all the time surreptitiously leaking small streams down the back of his neck, and filling his pockets with indigo colored puddles; and because, also, an umbrella would no more have protected a man against that storm, than a gun-cotton overcoat would have availed against the storm of fire that scorched old Sodom.
All the cotton waste of the hospitals, with their twenty thousand beds the old dressings and bandages come here, and after sterilisation and disinfection go to England for gun-cotton. Was there ever a grimmer cycle than this, by which that which feeds, and that which heals, becomes in the end that which kills!
Its motive power is in its tail, which is a screw propeller. It has lungs, consisting of a tank for holding compressed air. It has a stomach, composed of a pair of pneumatic engines which drive it through the water. Its body is fourteen feet long, more or less. Its head contains an explosive charge of 110 pounds of wet gun-cotton, with a dry disc of the same in its heart.
It may be conceived that a torpedo carrying 50 lb. of gun-cotton, capable of going 20 knots per hour, so that it would pass over a distance of 500 yards in about 45 sec., and yet be absolutely under control all the time, so that it can be constantly kept pointed at its target, would be a very unpleasant thing for an enemy to meet. Military telegraphy is a second use of electricity in warfare.
The enormous projectile was taken to the summit of Stony Hill. There enormous cranes seized it and held it suspended over the metal well. This was an anxious moment. If the chains were to break under the enormous weight the fall of such a mass would inevitably ignite the gun-cotton.
Before any of them could jump up, they heard a roar, which was followed by a mighty illumination. One of the neighbouring pines had caught fire, and blazed up as if it had been gun-cotton. The moment was critical. The little wind there was blew from the burning tree towards the spot where they sat.
After this, twelve small charges of gun-cotton were sunk in various directions, each representing a countermine of 500 pounds. These were discharged simultaneously, to demonstrate the possibility of extending the operations over a wide area. These miniature charges were sent down in small nets, and were quite unprotected from the water, so that the gun-cotton was wet when fired.
At the focus I place, a bit of black paper, with a little gun-cotton folded up within it. The paper immediately ignites and the cotton explodes. Strange, is it not, that the beam should possess such heating power after having passed through so cold a substance? In his arctic expeditions Dr.
Just about this time, to add to Morse's other perplexities, Doctor Charles T. Jackson began to renew his claims to the invention of the telegraph, while also disputing with Morton the discovery of ether as an anaesthetic, then called "Letheon," and claiming the invention of gun-cotton and the discovery of the circulation of the blood.
