As I have shown in describing several ceremonies still observed, a quartz crystal is used to deflect a ray of sunlight into the medicine bowl, and is placed in the center of a sand picture of the sun in certain rites called Powalawû; the crystal is also used in divining, and for other purposes, and is highly prized by modern Tusayan priests.
We landed on the left bank in order to determine the geographical position of the mouth, and found the latitude 38° 2' 4", and the longitude 122° 4'. After finishing this task, I ascended the highest hillock on the shore, which consisted of strata of slate and quartz, to admire the beauty of the prospect. On the south lay the enviable and important Bay of St.
One is a press copy of a letter dated January, 1864, addressed to Colonel Maxime Valois, from Hardin, asking him to sell him the quartz claims on the Lagunitas grant. The answer of Valois is written while recovering from his wounds. It reads: "TALLULAH, GEORGIA, March 1, 1864. "MY DEAR HARDIN: I have your letter, asking me to sell you the quartz leads on the Lagunitas grant.
It surpassed a thousand-fold the wildest of all the New York and California mining and quartz mining organizations of the last five years. Prudent financiers in London ran stark mad in calculating the dividends they must unavoidably realize upon investments in a business to be carried on in a distant country, and managed and controlled by a debating society or board of directors in London.
The result would be carbonates and sulphides of metals, earth, alkalies, and free quartz, but quartz and sulphides of the metals are soluble in solutions of carbonates and sulphides of the earths and alkalies, and the essential constituents of the ore might, therefore, readily be conveyed to openings in the vein where they would have been deposited on relief of pressure and diminution of temperature.
M. de Dolomieu sees no corrosion of quartz, or solution of that substance, upon the surface of the earth; from this, then, he concludes, that siliceous substance is not dissolved in that situation of things.
These rough heroes are led captive, even as Samson was betrayed by Delilah. The discovery of quartz mining leads Valois to believe that an American science of geologic mining will be a great help in the future. Years of failure and effort, great experience, with associated capital, will be needed for exploring the deep quartz veins. Their mysterious origin baffles the scientist.
It is dangerous for navigators, and so is likewise the Mogote which, at the distance of two miles from the western cape, is surrounded by breakers. On a very near examination of these rocks we saw the strata of gneiss inclined towards the north-west and crossed by thick layers of quartz. The destruction of these layers has doubtless created the sands of the surrounding beach.
The flexures of the gneiss are incomparably more irregular and confused than those of the quartz, and often contain flattened spheres of highly crystalline felspar, that cleave perpendicularly to the shorter axis.
The country beyond Won-ju was splendidly suited for an ambuscade, such as the people there promised me. The road was rocky and broken, and largely lay through a narrow, winding valley, with overhanging cliffs. Now we would come on a splendid gorge, evidently of volcanic origin; now we would pause to chip a bit of gold-bearing quartz from the rocks, for-this is a famous gold centre of Korea.
