Some of 'em, maybe, wouldn't hold a charge more than an hour, while others would have a shelf-life, fully charged, of as much as a year. Batteries don't work according to theory. If they did, potassium chlorate would be a better depolarizer than manganese dioxide, instead of the other way around.
They require the local care already insisted on, a mild plan of diet, and treatment to reduce any feverishness; and above all one medicine, the chlorate of potass, which in doses of four grains every four hours for a child a year old, is almost a specific.
"I wonder what the explosive could have been?" mused the chief aloud. "I don't know what was in the mortar in the first place, sir," Dick Prescott went on. "All Amos Garwood put in the mortar after we got there was some chlorate of potash. Then he put the pestle in and began to grind." "And then the explosion happened?" followed up Chief Coy.
"And now for the great finishing touch!" Amos Garwood placed on the board a fairsized wide-mouthed bottle. From where he stood, Dick could read the label on the bottle "Potassium Chlorate -crystals." "Chlorate of potash?" thought Dick. "That's what Dr. Bentley gave me once for sore throat."
The advantages derived from the development of the alizarine manufacture here, it was stated, will benefit other collateral industries, such as manufacture of soda, of ordinary sulphuric acid, bichromatic, and chlorate of potash, articles used in this manufacture.
If he were not in the field he was of her legislatures; if not there, then doing his duty in some civil office; if not there, wrestling with the management of worn-out railways; or, cool and keen, concerned in blockade running, bringing in arms and ammunition, or in the Engineer Bureau, or the Bureau of Ordnance or the Medical Department, or in the service of the Post, or at the Treasury issuing beautiful Promises to Pay, or at the Tredegar moulding cannon, or in the newspaper offices wrestling with the problem of worn-out type and wondering where the next roll of paper was to come from, or in the telegraph service shaking his head over the latest raid, the latest cut wires; or he was experimenting with native medicinal plants, with balloons, with explosives, torpedoes, submarine batteries; or thinking of probable nitre caves, of the possible gathering of copper from old distilleries, of the scraping saltpetre from cellars, of how to get tin, of how to get chlorate of potassium, of how to get gutta-percha, of how to get paper, of how to get salt for the country at large; or he was running sawmills, building tanneries, felling oak and gum for artillery carriages, working old iron furnaces, working lead mines, busy with foundry and powder mill.... If he was old he was enlisted in the City Guard, a member of the Ambulance Committee, a giver of his worldly substance.
The solution of chlorate of potash is made by diluting, one part of a saturated solution of the salt with ten parts of water. The use of the chlorate is simply as a solvent of iodine. Fats as Accelerators. The use of fats, oils, or greasy substances, has been one of the most emphatic prohibitions about the Daguerreotype plate.
Captain Harold C. Woodward of the Corps of Engineers, a Government specialist on explosives, held that if the amount of explosive, either trinitrotoluol, or an explosive made from chlorate of potash and benzol, required by the mine caskets found in Fay's possession, was fired against a ship's rudder, it would tear open the stern and destroy the entire ship, if not its passengers and crew, so devastating would be the explosive force.
The former is a salt which appears under the form of white crystals; when heated to a temperature of 400° it is transformed into chlorine of potassium, and the oxygen which it contains is given off freely. Now 18 lbs. of chlorate of potash give 7 lbs of oxygen that is to say, the quantity necessary to the travellers for twenty-four hours.
A sufficient quantity of chlorate of potassium and of caustic potash was placed at his disposal, together with provisions for eight days. And having shaken hands with his friends, on the 12th of November, at six o'clock A.M., after strictly informing them not to open his prison before the 20th, at six o'clock P.M., he slid down the projectile, the plate of which was at once hermetically sealed.
