A less courageous youth than Jack North must have given up then, but with the stern determination of his nature not to give up, he resumed his swimming, reaching the land half an hour later. "This is worse than before," he said ruefully, as he viewed his drenched figure, "for I did save my coat then. Yes, and my cargo of nitrate is still on the mountain waiting for me.
Such were the relations of these three states in 1878, when Bolivia, taking advantage of differences of opinion between Chile and Argentina regarding the Patagonian region, reimposed its export duty, canceled the Chilean concessions, and confiscated the nitrate deposits.
The dose of the active principle, aconitin nitrate, is about one six-hundredth of a grain. There are no color tests, no reactions, as in the case of the other organic poisons." I wondered what he was driving at. Was there, indeed, no test? Had the murderer used the safest of poisons one that left no clue? I looked covertly at Sato's face. It was impassive.
Other poisonous preparations are red precipitate, white precipitate, mercuric nitrate, the cyanide and potassio-mercuric iodide. Calomel has very little toxic action. Metallic mercury is not poisonous, but its vapour is. It is soluble in sixteen parts of cold and two of boiling water. Soluble in alcohol and ether, the latter also separating it from its solution in water. Symptoms come on rapidly.
Give upon the tongue, or in drink, half-drachm doses of nitrate of potassa, every three or four hours, until relief is obtained. If suffocation threatens, the operation of tracheotomy is the only resort. Cloths saturated with cold water, wrapped around the neck so as to cover the larynx, frequently afford relief. A purgative will also be found useful.
Give internally ten drops of Fleming's tincture of aconite every four hours, until five or six doses have been given; after which give one of the following powders twice a day: nitrate of potash, one ounce; Barbadoes aloes, one ounce; Jamaica ginger, half an ounce; pulverized-gentian root, one ounce; mix and divide into eight powders. If necessary a pound of salts may be given.
In loading nitrate a stout platform must be erected athwart ship, above the keelsons, in order that the foundation of the cargo may be laid level; for, as the sacked nitrate is piled, the pile must be drawn in gradually until the sides meet in a peak like a roof.
I picked the spot up with my own glasses and was aware of an instant chill as I saw the four masts of a great ship sticking out of the water. Whatever craft it was, it was as large as the Elsinore, and it had been but recently wrecked. "One of the German nitrate ships," said Mr. Pike. Captain West nodded, still studying the wreck, then said: "She looks quite deserted. Just the same, Mr.
"At the four applications, we probably used 1600 lb. of nitrate of soda per acre, and this would probably furnish more nitric acid to the plants than they could get from five hundred tons of manure per acre, provided it had been possible to have worked such a quantity into the soil. Never were finer plants grown.
But if used for this purpose it should be backed up with a liberal supply of bones and castor cake, or of bones and farmyard manure, or bones and top soil, as, if not so backed up, the result would be unsatisfactory, if not disastrous, seeing that the nitrate of soda, if applied alone, would cause the plant to wring out everything that was available in the soil.
