The famous blind traveler Holman describes the area around Ekaterinbourg, and the estate of the extraordinary Englishman, Joseph Major.
After involvement with a number of steam-engine and pump-related projects (and a large galvanic battery, in 1801) Major had worked at the St. Petersburg Bank Mint (Cyrillic initials "O.M." on Gold 5-Rouble Coins, 1797-1800) before settling in Siberia circa 1803. He built a steam-engine for A. Knauf's copper-smelter (1804) and with with son Alexander had an enterprise for the mass-production of engines.
Gold from his property was scant, a few pounds per year, but Major certainly had familiarity with Platinum, having employed it in his various professions.
He was murdered on his estate by Gold thieves in 1833.
From/to the Urals, news to/from St. Petersburg was 17-23 days delayed.
