His mate breaks the stone to about 2 in. gauge and feeds the box, lifting the ring from time to time to sweep off the triturated gangue, which he screens through a sieve into a pan and washes off, either by means of a cradle or simply by panning. In dollying it generally pays to burn the stone, as so much labour in crushing is thus saved.
Some of the marine shells may have lived on the spot; but the Cyclostoma and Limnea, being land and fresh-water shells, must have been brought thither by rivers and currents, and the quantity of triturated shells implies considerable movement in the waters. There occur no less than 137 species of this genus in the Paris basin, and almost all of them in the calcaire grossier.
"Now," said Staines, "does not that show you the presence of a mineral in your vegetable powder? I suppose they tell you it is made of white violets dried, and triturated in a diamond mill. Let us find out what metal it is. We need not go very deep into chemistry for that." He then applied a simple test, and detected the presence of lead in large quantities.
It is often desirable to burn your stone before crushing, as it is thus more easily triturated and will reveal all its gold; but remember, that if it originally contained much pyrites, unless a similar course is adopted when treated in the battery, some of the gold will be lost in the pyrites.
The model, about quarter size, was completed when my attention was called to an American invention, in which the same result was stated to be attained more effectively by blowing the mercury spray through the triturated material by means of a steam jet.
He had done according to his own artless conscience and the recipes of licensed physicians, and he looked no further, but pounded, triturated, infused, made electuaries, boluses, juleps, or whatever he termed his productions, with skill and diligence, thanking Heaven that he was spared to do so, when his contemporaries generally were getting incapable of similar efforts.
Sandstone cropped out in several places, and red quartz pebbles were very abundant in some parts of the river; the sands of its bed are so triturated that no one would ever surmise the existence of granitic rocks, at sixteen or twenty miles higher up. The whole country was flat; no hill was visible, but, towards the end of our day's journey, we crossed a few slight undulations.
The quantity of opium was then gradually decreased, but not totally omitted, as he continued to take about a grain morning and evening. January 17. He makes fourteen pints of water a day. Dr. Underhill now directed him two scruples of common rosin triturated with as much sugar, every six hours; and three grains of opium every night. Makes fifteen pints of water: sweats at night.
But then immediately occurs the startling difficulty, why has the sea worn out these great, though circumscribed, depressions on a wide platform, and left mere gorges, through which the whole vast amount of triturated matter must have been carried away?
Because of this remote relationship, so triturated indeed that it had really vanished into nothingness, Jack Starland and Warrenia Rowland called themselves cousins. It was just like the headstrong, impulsive, mischievous youth to go still further.
