Folk interested in eccentric early steam inventions, such as that described on my page about chain haulage, might also be interested in the invention of Captain George Beadon RN, as described on the invaluable Grace’s Guide site.
Her late Majesty Queen Victoria, by the Grace of God of the United Kingdom of Great Britain and Ireland Queen, had the foresight to acquire a photograph of Captain Beadon’s vessel and to make it available on tinterweb.
Captain Beadon’s route to London took him through Keynsham: that’s K-E-Y-N-S-H-A-M.
