Mining
“An unprofitable mine is fit only for the sepulcher of a dead mule.”
― T.A. Rickard
Even as the Argonauts rose in rebellion in 1852 and then subsided in defeat the year after, their world was already vanishing.The old Californie dream, that a man could wander up to a stream and fish out a fortune in an afternoon was becoming a fading memory. This was not due to poor French policy, feckless foreign miners or divine disfavor, whatever the varying slogans might have suggested. It was due to simple geology. The easy placer deposits, those fabled streambeds laden with gold, had been thoroughly plundered by 1853, exploited by years of tenacious Gold Rushers. It was not that Californie was out of gold, not by any means. It just meant that the rest of the mineral wealth lay deeper down, in pockets that would require more effort, and ingenuity to reach.
The first method of ‘mining’ in Californie had been the simplest. A would-be prospector would simply find flecks of gold in a streambed or tangled in the roots of overhanging plants and pick them ‘as a man would blackberries’. Even in Californie however, such a bounty was rare and most early mining used simple gold panning methods. The process was basic, where a prospector would use a pan to scoop streambed deposits and ‘wash’ it vigorously, allowing the heavier gold to sink to the bottom. A skilled miner would quickly shake out the lighter dirt and water, leaving only the valued gold flecks. While cheap, panning was back-breaking labor that limited even the most talented prospector to about a single cubic meter of gravel processed per day.

A slightly more sophisticated method was using a so-called ‘rocker box’ or ‘cradle’ which was basically a larger, slightly mechanized pan, resting on rockers. The miner would pour in gravel and water, shake the entire machine, and various trays would catch the gold, while allowing the unwanted debris to flow away. While larger than a simple prospectors pan, even a rocker was usually a home-built device that could be managed by a single man, allowing a miner to triple his output, to three cubic meters a day.
It was these simple methods that characterized the initial Gold Rush boom that became globally famous. Images of grizzled men leaning over waterways, panning gold became synonymous with the Rush. Despite the romance and legends of the early goldfields and their ecosystem of ville champignon (mushroom towns) however, gold output in these early years was quite low due to these simple methods. Worse, panning and rocking were inconsistent, impossible to perform during high water floods when streams became inaccessible torrents of whitewater or were frozen solid during frigid winters. To combat these problems, and to deal with the fact of increasingly stripped streambeds, new mining techniques were needed.
The first advancement were simply larger rockers, which eventually morphed into the ‘sluice’, based on mill-races in Europe. Pioneered by French miners, the sluice took the idea of the simple panning for gold to the logical conclusion. Long troughs were made of wood, often over ten feet long, with rough bottoms (sometimes wooden ridges, sometimes simply old carpet) in the bottom to catch the heavy gold, while the water and unwanted rocks ran over. These large contraptions, which often required entire gangs of men to service them, could greatly increase the rate of gravel production. With a well made ‘Long Tom’, as the sluice boxes were nicknamed, a miner could process a cubic meter of gravel an hour, nearly ten times faster than the old prospector and his pan.

Other techniques were tried as well. Dredging, where a ship would scoop up tons of silt from river bottoms was promising but quickly faltered on poor technology. Drywashing, where air blown by bellows is used to blow off the lighter dirt was also attempted but quickly relegated only to the driest areas due to inefficiencies. In other places entire streams were diverted to erode new areas, or to expose desired gravel beds. However, the entire California mining world, and the local landscape, would be transformed by a Frenchman’s ingenious new method in 1854.
Henri-Émile Bazin was a young French engineer who, like so many miners, had avoided the entire Argonaut rebellion to focus on finding gold. Trained in hydraulics, he put his previous education to use by coming up with an entirely new way to find gold deposits. Previously miners had been forced to only explore deposits near the surface, already exposed by natural erosion. Bazin however, concluded there might be a way to expose as yet hidden gold veins, by use of pressurized water to blast away the topsoil and layers of unwanted overburden.
His first attempt involved creating a small water reservoir, and then forcing the water into ever smaller pipes, focusing the building pressure. Handling the nozzle proved difficult but Bazin came up with an elegant system of counterweights that allowed a single miner to point the gushing torrent. The rushing water could erode entire hillsides in an afternoon, washing into giant sluices built downhill from the mining site. Bazin’s invention, while primitive at first with leather hoses and wooden nozzles, was quickly adopted by many miners throughout the goldfields. The reason was obvious. A large hydraulic mining operation, supplied with adequate water, drainage and men to work the sluices, could process hundreds of cubic meters of gravel an hour, an order of magnitude more efficient than older methods.
Miners could erode away entire hills with Bazin's new methods.
Another way of accessing gold that was too deep even for Bazin’s hydraulic method was the traditional practice of sending shafts under the earth, seeking riches. Called quartz mining in Californie (due to the frequent fact that gold veins were mixed with quartz) it was the most difficult and intensive form of mining, involving considerable engineering and effort. At first it was ignored during the early Gold Rush due to seeming unnecessary. Who wanted to dig down into the earth when gold seemed so plentiful on the surface? As time went on however, and streambed deposits vanished, some started looking deeper.
One of the first was the aptly named Gold Hill, on the outskirts of the northern goldfields. First explored in 1851, it had become a flourishing gold producing site, complete with wild ville champignon. Literally millions of franc’s worth of gold was hauled out of the shallow pits and shafts dug there. By 1856 however, a more serious effort was undertaken and a systematic network of underground tunnels dug with great success. Inspired by such work, other quartz operations began forming throughout the goldfields. Many became considerable concerns hiring hundreds of miners, engineers, managers and experts. Most highly sought after in the latter category were Cornish tin miners, considered the finest underground men in the world.

These new technologies came at a high cost of course, and not merely financial ones. As mining further industrialized, it became ever more dangerous for the workers involved. Poorly built sluices slipped and crushed, cheaply built tunnels collapsed, and men drowned in sudden floods caused by broken hydraulic dams. These brutal results of large scale industry often fell on the poorest and most desperate workers, those without skills or capital. Even more striking were the costs on the landscape. Hydraulic mining in particular was devastating on the ecosystem, consuming not only local water sources but also literally stripping away the soil, and filling every watercourse with tons of gravel and dirt. This pollution caused flooding and erosion downstream and made the water useless for any other purpose. Even quartz mining left considerable tailings and leftover piles of rock littering the landscape, much of it highly acidic.
Other changes were also visible in Californie society. As mining grew more capital intensive, it dramatically altered how the system operated. Gone were the heady days of a single miner and his shovel earning millions due to luck and hard work. Replacing it were large corporations and cartels which required considerable financial, organizational and logistical resources. The small claims that had previously dominated were soon obsoleted by gigantic operations covering many acres of ground. A single miner was transformed from his own master, into a small cog in a much larger gold generating machine. This trend was accelerated by the French authorities who much preferred working with large corporations who they could more easily assess, tax and negotiate with.
This trend marginalized many groups that had flourished during the less ordered and hierarchical periods. Women in particular were losers in this emerging new order. During the Rush they had been merchants, landlords, and in some cases miners themselves. Their skills had been in high demand in the overwhelmingly masculine world of the goldfields but as big business consolidated, they were pushed out. Companies did not hire women, and preferred to do business on a large scale with other male-oreinted enterprises.Female entrepreneurs were pushed out of business, replaced by men.
Native Americans also suffered from a similar shift in attitudes and practices. Their place during the Rush had never been very secure of course, dealing not only with racial animosity and discrimination, but outright violence. Despite intermittent French protection, almost every tribe suffered from the hordes of gold miners. Still, some had managed to hold onto claims and even become rich through mining success. Even this small consolation was swept away however, as mineral extraction became more regimented. Companies would not hire natives and their claims were bought out or taken over, with even less compensation. The newly enhanced destruction of the landscape due to hydraulic mining merely sealed the fate of the coastal Native Americans, who increasingly found fewer palatable choices.
By 1860 the old era of the Gold Rush had faded away, replaced by an increasingly centralized and French set of businesses. The wild ville champignon were slowly replaced by more organized settlements or, in some extreme cases, virtual company towns. Faced with this growing downward economic pressure many miners did the obvious and fled. Heading out for the L'Arrière-pays, these men took their considerable skills and experience out into a search for new finds, where a fortune could still be made by a single man.
Gone were the days of men at the side of a stream, replaced by engineering projects on a vast scale financed by big business.
This questing prospectors took white settlement to the remote interior of Californie, and beyond, in search of gold. Canvassing the Nouveau-Mexique and Transierra, as well as hidden pockets of Californie proper, they set off a number of miniature gold rushes in the 1860’s. Some such as the Kern Rush in 1861 and the Gloire Strike in 1865 turned out to be duds, promising sites undone by geography but others turned out to be substantial. Large finds were made both at the Gila River, near Fort Yuma and most famously in the Transierra at Virginia City, with the fabled Comstock lode. Other small finds also blossomed in this period, only lasting a short time.
All followed the same sequence of events. A small group, or even solitary prospector would find a new promising claim. Word would spread and create a stampede of other miners rushing to the side, eager to stake a claim early. Then, as the diggings started, others would follow. Traders, hustlers, prostitutes and engineers, hoping to profit from the sudden eruption of the mushroom town. For a while the place would flourish, roads built, houses erected, local government established. In some places, such as Virginia City this boom could last years, creating a new metropolis but even in small towns, the change could be dramatic. A rural gulch could host men from all over Californie, with culture, economy and politics seeming to appear out of thin air. Then the surface gold would be played out and the miners faced a stark choice. Move on to the next strike, or hold on for the next inevitable arrivals.
Then, the coastal French businessmen, or at least their agents and money. Claims would be bought up, miners hired as labor and contracts concluded with the local authorities. Real mining would start then, shafts laid deep into mountains and hills, canyons drained or depressions filled with water. The entire landscape would be transformed, just as the old Gold Rush goldfields had been. And such the miners unwilling to endure such conditions would head out, and the cycle began anew.
