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.

John Ditchfield very kindly photographed some airholes on the Kennet & Avon Canal and sent on the photos. The captions are his comments.
Good length of overflow. Water flowing.
(Rebuilt) small openings are above the level of the top of the adjacent lock gate. However, just upstream there is another paddle or sluice gate on the canal side (next photo), so perhaps that is used to control the level.
The upstream paddle or sluice gate.
Overflow in action, preventing water overflowing gates.
Note: this lock connects the canal with the River Avon, and the building in the background was a steam pumping station, presumably for topping up the canal from the river.
Many thanks to John for taking the trouble.
