"Placer" Quotes from Famous Books



... origin of sedimentary ores. Certain mineral deposits, like the "Clinton" iron ores, the copper ores in the "Red Beds" of southwestern United States and in the Mansfield slates of Germany, many salt deposits, and almost the entire group of placer deposits of gold, tin, and other metals, are the result of sedimentation, from waters which derived their materials from the erosion of the land surface. It is sometimes possible from the study of these deposits to discover the position and configuration of the shore line, the depth of water, ...

... men armed with Kentucky rifles, which were not only muzzle-loaders, but of small calibre and less effective than the ordinary .32 calibre rifle of to-day, were hunting deer on the divide between Volcano and Shirttail Canyons in Placer county. In the heavy timber on the slope they encountered a large Grizzly coming up out of Volcano Canyon. The bear was a hundred yards distant when they saw him and evinced no desire for trouble, and two of the hunters were more than willing to give ...

... no geologist, but he had seen enough of it to recognize that prospecting is an art. Men certainly strike a vein or alluvial placer by the merest chance now and then, but the trained man works from indication to indication until, though he is sometimes mistaken, he feels reasonably sure as to what waits to be uncovered by the blasting charge or ...

... work with the U. S. Geological Survey in the California Sierras around Lake Tahoe and the American River under Waldemar Lindgren, one of the greatest of American scientific mining engineers. This work was on the relations of the famous Sierra placer gold deposits to the original gold-bearing veins and lodes, and resulted in tracing those comparatively recent placers back to the old mountain slopes and valleys. It was a fascinating problem successfully carried ...

... terrible winter night the whole town was destroyed by fire, and now that the miners were drifting to other camps, few of the shacks were rebuilt. Of the six thousand that had been, scarcely threescore remained. A few trappers ran their lines out from the town, a few men had placer claims in the old diggings, two or three woodsmen made precarious livings as guides for such wealthy men as came to hunt moose and caribou, and Bradleyburg's course was run. The winter cold had triumphed at last, and its curse was over the city from October till June. The ...

... the mountainous nature of the country; but considerable industrial activity prevails there. The inhabitants weave fine straw hats from the fibre of the leaf of the buri palm-tree (corypha sp.), manufacture pandanus mats, and carry on a profitable trade at Mauban with the placer miners of North Camarines. The entire breadth of the road is covered with cement, and along its center flows, in an ...

In another placer, which embraces an extension of seven leagues, they also extract some gold in dust in quantities as insignificant as those which result from the sands of the ...

... and fur trading. With the union of the two rival companies in 1821, the Hudson's Bay Company became the sole authority on the Pacific coast. Settlers straggled in slowly until, in the late fifties, the discovery of rich placer gold on the Fraser and later in the Cariboo brought tens of thousands of miners from Australia and California, only to drift away again almost as quickly when the sands ...

... in the narrow valley of one of the Sacramento's northern tributaries, as, in fact, it was throughout the whole region of "placer diggings;" for it was October of a dry year, and water had failed early in all the camps. The afternoon of a long, idle day at Wilson's Bar was drawing to a close. The medium through which the sun's hot rays reached the parched earth was one ...

... be better for him to provide for his immediate happiness, he asked, and let the future take care of itself? Even while he asked the question another woman intruded her face: she was slim, and fair, and delicately made, and was disguised in the male attire of a Yukon placer-miner. She seemed to be asking ...

... sealskins off other people's beaches, and there was zest enough in that, in view of the probability of the dory turning over, or a gunboat dropping on to you. Then there was a good deal of very genuine excitement to be got out of placer-mining in British Columbia, especially when there was frost in the ranges, and you had to thaw out your giant-powder. Shallow alluvial workings have a way of caving in when you least expect it of them. After all, however, I think I ...

... another spot is the corpse of some wealthier person wrapped in silver tinsel. Not the least interesting of the sights is that of men and boys here and there engaged in dipping up mud from the bottom and washing it in pans similar to the gold-pans of placer-miners; they make their livelihood by finding occasional coins and ornaments, accidentally lost by bathers. A very unique and beautifully carved edifice is the Nepaulese temple; but the carvings are ...

... he knew, always carried him back to the time when he was a car-boy at the Big Dipper Mine in Placer County, ten years before. He remembered the years he had spent there trundling the heavy cars of ore in and out of the tunnel under the direction of his father. For thirteen days of each fortnight his father ...

... a corner of the bed among the spruce boughs, and pulled out a leather sack. She untied the mouth and ran out into my hand as pretty a stream of gold as I have ever seen—coarse gold, placer gold, some large dust, but mostly nuggets, and it was so fresh and rough that it scarcely ...

... so-called 'placer claim'—experts have reported against it. McFarlane has protested against it, but nothing is done. The mill is also on deeded land, and together they are a plague spot. I'm their enemy, and they know it; and they've threatened to burn me out. Of course they won't do that, but they're ready to ...

... that, Cap," spoke up one of the miners. "This is goin' ter be one of ther best minin' camps in ther middle part of Nevada, an' there ain't no mistake on that. It's most placer minin' that we've been doin' here, 'cause we ain't got no machinery ter go down deep in ther ground. But that there's big deposits down under us there ain't no doubt.

... as this is the Frenchman's notion of the presence of guns in the canons' seats: "L'Archevque de Cantorbery avait fait placer des canons dans les stalles de la cathdrale.'' He quite overlooked the word chanoines, which he should have used. This use of a word similarly spelt is a constant source of trouble to the translator: for instance, a French translator of Scott's Bride of ...

... a cessation of mining in many parts of the mountains. Of course it can be well understood that the immense prosperity of the city, the prosperity that allowed it to recover from severe financial disease, had its spring in the placer mines. A constant stream of fresh gold was needed to shore up the tottering commercial structure. With the miners out of the diggings, matters changed. The red-shirted digger of gold had little idea of the value of money. Many of them knew only the difference ...

... the town. The man who directed me how to find it, I discovered had not the remotest idea who Bret Harte might be; "John Brown" would have answered the purpose equally as well. In fact, all through the seven counties I traversed—Tuolumne, Calaveras, Amador, El Dorado, Placer, Nevada and Yuba—I found Bret Harte had left but a hazy and nebulous impression. Mark Twain, Prentice Mulford, Horace Greeley, Bayard Taylor, even "Dan de Quille," seemed ...

... and then turn in steam. Then they rip out the ground down twenty feet with the big scoops of the dredges. They just have water enough to float the dredges. Everything is worked and washed right on the dredge. It beats placer mining a whole lot. But a few men can work one of these dredges, and then a few men get all the money they ...
