The lower grades have always been found to be unstable and subject to spontaneous decomposition. Nitro-glycerine has also been erroneously thought to be a very unstable compound. But experiments have proved that, when made pure, it is perfectly stable.
Arriving at the well which was to be shot the boys saw a number of men. They had just finished using the borer, and had gone down a number of hundred feet without striking oil. It was, therefore, decided to "shoot it," that is, tin cylinders, containing in all about two hundred pounds of nitro-glycerine, were to be lowered into the hole, one on top of the other.
When we found that more attention was paid to men suspected of crime in their own countries, and men who were believed to be plotting to assassinate kings, dad said it would be a good joke if a story should get out that he was suspected of being connected with a syndicate that wanted to assassinate some one, so I told a fellow that I got acquainted with that the fussy old man that tried to ride a glazier without any saddle or stirrup was wanted for attempting to blow up the president of the United States by selling him baled hay soaked in a solution of dynamite and nitro-glycerine.
The long, tin cartridges were tied together securely, with wads of paper between to prevent them from rattling; the cans of nitro-glycerine were placed by the window, where they could be gotten at readily, and Bob produced a three-cornered piece of iron, about four feet long, which weighed twenty or thirty pounds.
"I intend to be of every possible assistance to you, and when I cannot do that, if you are still obliged to labor, I will extract no small amount of enjoyment out of your farm-house and its surroundings. But at any time that you have a few hours to spare, I will be only too well pleased to meet with any adventure, from nitro-glycerine blasts to the perils of trout-fishing."
A shell, filled with fifty or a hundred pounds of dynamite or nitro-glycerine, would be sure to do terrible damage anywhere within a radius of three miles around Madison Square. A second balloon dropped its charge into the receiving reservoir in Central Park, luckily doing no damage, but throwing up a tremendous jet of water.
It was under the action of this cylinder, charged with some explosive substance, nitro-glycerine, picrate, or some other material of the same nature, that the water of the channel had been raised like a dome, the bottom of the brig crushed in, and she had sunk instantly, the damage done to her hull being so considerable that it was impossible to refloat her.
Young students in chemistry, when they learn that nitrogen is distinguished by the weakness of its affinities for other elements, and its consequent great inertness as a chemical agent, are often astonished to find that its compounds such as nitric acid, nitre, which gives its explosive character to gunpowder, nitro-glycerine, gun-cotton, and various other explosive substances which it helps to form are among the most remarkable in nature for the violence and intensity of their action, and for the extent to which the principle of vitality avails itself of them as magazines of force, upon which to draw in the fulfillment of its various functions.
"Come along, there's nobody here!" he cries. Fru Falkenberg gets up and says: "Madman! Whatever are you doing?" But she goes towards him all the same. "Doing?" says he. "What else should I do? Love isn't glycerine it's nitro-glycerine." And he takes her by the arm and leads her in. Well, 'tis their affair....
To arrive at the knowledge that this compound would constitute the best smokeless powder has required a great deal of experimenting. It was first thought that gun-cotton colloid, without any nitro-glycerine, that is, gun-cotton dissolved and dried, would burn more slowly, keep better, and give better ballistics than it would if combined with nitro-glycerine.
