Infinitely refined in structure, they nevertheless have the power of contraction and dilatation, which power is governed by nervous action of a special kind." Now, there are certain chemical agents, which, by their action on the nerves, have the power to paralyze and relax these minute blood-vessels, at their extreme points. "The whole series of nitrates," says Dr.
The liquid drawn off is crystallized by chemical treatment and further evaporation, and from it is obtained iodine, an ounce of which is worth as much as one hundred pounds of saltpetre. From eighty to one hundred million dollars' worth of these nitrates are dug out and sold each year. Great Britain takes about one-third of the entire product and Germany one-fifth.
At last he had to rest again, and thinking himself safe for the time being he set about cleaning his hands and face, and also his outfit. "This is certainly treasure hunting with a vengeance," he mused. "I think I would have done better had I stuck to the nitrates. Maybe I'll lose my life and the vultures will pick my bones, just as they did poor Plum's."
If the Congress would giant the Secretary of War authority to lease the nitrate plant on such terms as would insure the largest production of nitrates, the entire property could begin to function. Such a division, I am aware, has never seemed to appeal to the Congress. I should also gladly approve a bill granting authority to lease the entire property for the production of nitrates.
The nitric ferment exists in all soils and in all latitudes, and converts the ammoniacal matters carried along by the rain into nitrates of a form most assimilable by plants. It therefore constitutes one of the important elements for fertilizing the earth. Finally, we must refer to the numerous bacteria that occasion putrefaction in vegetable or animal organisms.
At the supper table Wade and Arcot reported to the others the curious constants they had discovered for coronium. It was not attacked by any acid except boiling selenic acid, since it formed a tremendous number of insoluble salts. Even the nitrate violated the long-held rule that "all nitrates are soluble" it wouldn't dissolve. Yet it was chemically more active than gold.
A gentleman who lives in Santiago told me how he could set out tomato plants in the best soil, take a little handful of nitrates that look like common salt, dissolve it in water and pour it on the soil and the difference it would make is almost unbelievable. But a spoonful dropped on the plant will kill it. It never rains on these nitrate beds if it did they would be worthless.
There are apparently several different kinds of nitrifying bacteria with different powers. By the action of other species still higher nitrogen compounds, including the nitrites, are further oxidized and built up into the form of nitrates.
This appeared to be devoted to minerals, and the sight of a block of sulphur set my mind running on gunpowder. But I could find no saltpeter; indeed, no nitrates of any kind. Doubtless they had deliquesced ages ago. Yet the sulphur hung in my mind, and set up a train of thinking.
Why disregard the native worth of annatto and nitrates? Baron Beecham or Lord Sunlight is a first-rate name. As it is, we make petty and puerile distinctions. Beer is in, but whiskey is out; and even in beer itself, if I recollect aright, Dublin stout wore a coronet for some months or years before English pale ale attained the dignity of a barony. No Minister has yet made chocolate a viscount.
