But in spite of accidents, calamities, the rise and fall of stocks, Washoe “zephyrs,” and other things, the work goes steadily on, and the mines of Nevada, year after year, continue to hold their place as the greatest and most remarkable silver mines in the world.
WORKING A MINE.
During the month of April, 1877, the shipments of the California mine have been $1,600,000. If we read the brief announcement, every month, on a certain day, that a certain mine has paid a dividend of $1,080,000, we have not the slightest idea of what is necessary to be done in order to make such an announcement possible. Every one who ever owed a note in a bank, knows that thirty days is a very brief period of time. To cause a mine to produce $60,000 in a single day, is a tremendous feat; to continue this product daily, through weeks and months, almost without variation, is a marvel. It takes forethought, endurance, judgment, and nice calculation, such as very few men possess in this world. The ore from which this mighty yield is extracted, lies hid away almost a third of a mile below the earth’s surface. It lies where consuming heat and baffling waters join their forces to try and drive away the invading miner. While the ore is being hoisted, every month, 1,250,000 feet of lumber has to be lowered and put in position, to keep safe the weakening caused by the mighty excavations. While one level is being worked, another has to be explored, for a drain of 500 tons of ore per day would soon level a mountain down. Then the Comstock is an uneasy fissure. In a single week, sometimes the swell of the ground shivers into splinters fourteen-inch square timbers. Shafts and drifts and inclines and tracks have to be watched incessantly, for a mine, like a glacier, seems ever to be working. This is all below ground. Above the surface is a world of machinery, always to be kept in order—steam engines, air engines, cables, cages, air pipes, pumps, and all the multiplied devices intended to expedite the work and lessen the dangers of mining. Five hundred men have to be lowered into and hoisted from the depths daily. Three hundred cords of wood have to be provided daily for fuel. And there must be no delays, no serious accidents. The needed repairs must be anticipated and provided for; the accidents must be anticipated and guarded against; the explorations must be carried on months in advance; the supplies must never fail. A vast space of forest land, thirty miles away, has to be denuded of its timber, yearly, to fill the insatiate maw of this one mine. It requires 15,000,000 feet of timber, and 100,000 cords of wood, annually, to supply the mine, and to furnish fuel to hoist and reduce the ores. How many can appreciate the ability necessary to carry on this work without any mistakes? Many a man of mind sufficient to accomplish the feat, would fail through sheer lack of physical strength. The work means being up at five o’clock in the morning; means two or three daily journeys into the depths, and when anything unusual happens, it means standing guard day and night, like a ship’s captain in a storm, until the trouble is over. It means a mind large enough to take in the immense work going on at a glance, yet careful enough to include its smallest details, and exact enough to anticipate the wants of the enterprise months in advance. For ten months, the California mine has monthly given up this tremendous yield.
LIST OF BONANZAS.
The following list of the bonanzas of the Comstock will be interesting to all who are watching the marvelous history of that mammoth vein:
1. Ophir and Mexican.—Discovered on the surface, and extended 500 feet in depth. Average width of ore, 15 feet; cubical contents, 112,000 tons; approximate value of ore, $22,000,000.
2. Gould & Curry.—Extended from the surface to the depth of 500 feet. Average width of ore, 15 feet; length along the vein, 500 feet; cubical contents, 190,000 tons; value of ore, $37,500,000.
3. Savage.—This was a continuation of the Curry bonanza, but not so rich. The ore continued down in the Savage claim to the very bottom of that mine, which is now 2,300 feet below the outcroppings.
4. Hale & Norcross bonanza.—This body was struck at a depth of 450 feet. It averaged 10 feet in width, was about 200 feet long, and stretched down to the 1,200 foot level. Cubical contents, 75,000 tons; value, $5,500,000.
5. Chollar Potosi bonanza.—struck at a depth of 500 feet; width of the vein worked, 100 feet; has extended with but few interruptions down to the present bottom of the mine, which is over 1,700 feet. Cubical contents, 1,500,000 tons; value, $24,000,000.
