The brief – but vastly profitable – heyday of Parys Mountain

In the latest Age of Invention newsletter, Anton Howes discusses the engine behind the meteoric rise of Britain’s “Copper King”, Thomas Williams:

At the time More visited, Thomas Williams had only just begun his rapid rise to power. He was already a major industrialist and grown stupendously wealthy. When More asked about his stables, Williams apparently could not even estimate how many he possessed to the nearest ten. But Williams not yet even master of the mountain.

Nonetheless, the mining was well underway. The closest port, Amlwch, was already connected to the mountain by a new road that had been built for the Parys Mine Company’s sole use. Having not long ago been a village of just six houses, Amlwch had turned into a bustling port.

The mine itself was a source of fascination. “This differs from any mine I had ever seen or perhaps is anywhere else to be found, for the ore here instead of being met with in veins is collected into one great mass, so that it is dug in quarries and brought out in carts without any shafts being sunk”. Instead, the miners hollowed out the mountain itself, forming vast caverns that they supported by simply leaving vast columns of the ore untouched. He noted at least four or five of these caverns with ceilings forty feet high, with columns of yellow ore: “the whole seemed like the ruins of some magnificent building whose pillars had been of massy brass.”

It’s a fascinating insight into what Parys would have very briefly looked like, because today there is so little of the mountain left. Indeed, some of the caverns More got to see were already collapsing, with the rubble then needing to be sorted. He describes how one such piece of rubble — a two-ton chunk of ore — had to be bored, the cavity rammed with gunpowder and sealed with stones, and then exploded. “They are continually blowing up parts of the mine”, he noted, and was informed that the part of the mine he was visiting alone got through 10-12 tons of gunpowder per year. The mountain was disintegrating, punctuated by the occasional boom.

And as though that were not dramatic enough, the whole place smelled like hell. When More visited there were some seventy vast kilns upon the mountain for calcining the ore, burning off its sulphur. Each kiln held some 2,000 tons of ore, and when ignited with a little dried vegetation or coal it was so sulphurous that it took four months of furious burning for the ore to be sufficiently calcined. He noted that one had to keep to the windward side of the kilns, as “the fumes arising from them are very disagreeable and destroy all vegetables for a considerable distance around them.”

If you like the CRTC regulating the internet, you’ll love having them regulating video games!

Not satisfied with strenuously trying to break the internet for ordinary Canadians, the Trudeau government is now being lobbied to introduce regulation of video games, too:

Bill C-11 may have receded into the background of CRTC consultations and government policy directions, but Canadians concerned with user content, video game and algorithmic regulation would do well to pay attention. Lobby groups that fought for the inclusion of user content regulation in the bill have now turned their attention to the regulatory process and are seeking to undo government assurances that each of those issues – user content, algorithms and even video games – would fall outside of the scope of the regulatory implementation of the bill. In fact, if the groups get their way, Canadians would face unprecedented regulations with the CRTC empowered to create a host of new obligations that could even include requirements for Youtubers and TikTokers to register with the Commission. With a new Heritage Minister in place, the submissions raise serious concerns about whether the government will maintain its commitments regarding scoping out users, video games, and algorithms.

The most troubling publicly available document comes from a coalition that calls itself ACCORD, representing songwriters, composers, and music publishers. The group has posted its submission to the government’s consultation on the draft policy direction to the CRTC on Bill C-11. All submissions are not yet posted, but I should note that I also submitted a brief document, calling on the government to fully honour its commitment to exclude user content and algorithms from regulation and to establish limits on discoverability regulation.

The government’s draft direction had called for “minimizing” algorithmic regulation and the exclusion of user content and video game regulation. The music lobby is now calling on the government to rollback virtually all of its commitments on these issues. The draft direction states:

    The Commission is directed not to impose regulatory requirements on

    (a) online undertakings in respect of the programs of social media creators, including podcasts; and

    (b) broadcasting undertakings in respect of the transmission of video games.

The lobby wants virtually all of this removed, deleting references to online undertakings and video games. Moreover, the directive speaks to Section 4.2, stating:

    In exercising its powers under section 4.2 of the Act, the Commission is directed to set out clear, objective and readily ascertainable criteria, including criteria that ensure that the Act only applies in respect of programs that have been broadcast, in whole or in significant part, by a broadcasting undertaking that is required to be carried on under a licence or that is required to be registered with the Commission but does not provide a social media service.

Here too the lobby group wants most of the paragraph deleted. And while the government directed the CRTC to minimize algorithmic regulation for discoverability purposes, the groups wants those limitations removed as well. In short, the lobby groups validate the concerns expressed by thousands of Canadians that Bill C-11 opened the door to the regulation of user content, video games, and algorithms.

French 75mm of 1897

The French 75 is widely regarded as the first modern artillery piece. It was the first field gun to include a hydro-pneumatic recoil mechanism, which kept the gun’s trail and wheels perfectly still during the firing sequence. Since it did not need to be re-aimed after each shot, the crew could reload and fire as soon as the barrel returned to its resting position. In typical use the French 75 could deliver fifteen rounds per minute on its target, either shrapnel or high-explosive, up to about 8,500 m (5.3 mi) away. Its firing rate could even reach close to 30 rounds per minute, albeit only for a very short time and with a highly experienced crew. [wikipedia: https://en.wikipedia.org/wiki/Canon_d…]

The concept for the gun anticipated future conflict being a war of manoeuver — with massed infantry and cavalry attacks — based on the experience of the wars of 1870-1872. Consequently the gun was designed to be able to be moved easily, set up quickly and fire antipersonnel shells (shrapnel) rapidly, and without the need to reset the carriage after each shot. Two critical components were the cased ammunition (shell and cartridge as a single unit) and a recoil system that completely absorbed the recoil forces and returned the gun to its original position without disturbing the gun’s position.

This animation shows the actions necessary to prepare the gun from its “travelling” state to operational state. The carriage has to be “locked” into a fixed position and levelled. The operation of shrapnel shells depends upon setting a time fuse to explode the shell just in front of an attacking force, to shower them with balls, and demonstrates the French Débouchoir mechanical fuse setter that allowed time fuses to be set rapidly and accurately. The liquid (oil) and air (pneumatic) recoil mechanism used a “floating piston” — on one side hydraulic oil and on the other compressed air. The design must keep these two separated while allowing the free piston to move rapidly. The French design laid great emphasis on seals made of silver – being soft enough to conform to the sleeve housing, but as reported by the US when they started manufacturing the 75mm, the key element was highly precise machining of the sleeve housing the free piston.

The French 75mm of 1897 was of less use with the introduction of trench warfare, where howitzers and mortars being the primary artillery, but the 75mm retained some value, one use being firing shrapnel shells at aircraft. A longer time fuse had to be developed to reach the altitude that some aircraft flew at.

QotD: How pre-modern cities shaped the surrounding landscape

Filed under: Books, Europe, History, Quotations — Tags: , , , , — Nicholas @ 01:00

When it comes to shaping the landscape outside of the city – our main point of investigation – the key element of the pre-modern city that matters is the intense demand it creates for agricultural products that the non-farmers who live in the city cannot produce themselves, chiefly (but not exclusively!) food. The intensity of that demand scales with the size of the city. A small town might only really shape land-use and farming patterns out a few miles; a huge mega-city like first century Rome (c. 1m people) re-shapes land patterns for hundreds of miles, its economic influence intruding into the territory of other, smaller cities.

Every town or city, of course, will be different. For agricultural societies especially, local terrain sharply constrains possible land uses. Some land is simply too wet or dry or rough or rocky or infertile for this or that purpose. In a modern city, apartments or factories or offices can be built almost anywhere; the sort of land suitable for intensive farming is more limited. This is even more true for pre-modern societies working without modern fertilizer, without electric-powered irrigation and without the industrial technology to massively reshape terrain (draining swamps, filling ravines, flattening hills, irrigating the desert, etc – some of these can be done with hand tools, but not to the extent we can today).

Still, we want to begin thinking about how cities impact the land around them without all of these difficult and confusing variables. We want to image a city, isolated and alone in the middle of an endless, flat and featureless plain. This is exactly what J. H. von Thünen did in The Isolated State (Der isolierte Staat). This kind of exercise can give us a baseline of what the landscape around a decent sized city might look like, which we can then modify to respond to different terrain, technology and social organization.

(Note: I would be remiss if I didn’t note that my discussion of these ideas owes heavily to Neville Morley’s Metropolis and Hinterland (1996), where he applied this very method to the city of Rome and its hinterland (and also first introduced me to von Thünen’s ideas). That book and also his Trade in Classical Antiquity are both great books to give a read if you want to begin building a sense of how pre-modern economies work).

The key factor von Thünen looks at is transportation costs. For a society without trains or trucks, moving bulk materials of any kind over long distances is extraordinarily expensive. Moving grain overland, for instance, would cause its cost to double after 100 miles. Thus land close to our theoretical city is extremely valuable for production, while land far away is substantially less valuable (because the end goal is transporting the agricultural production of that land to the city). As a result, transit costs – and thus distance – dominates how cities influence land-use patterns (along with population, which determines the intensity of the city’s influence).
