“The story to my mind is technically accurate as the description of the propelling machinery and equipment which would be fitted in a ship with compound engines of vintage 1850-70.But after all, if the fictional repairs had not been performed there would have been no story – to our great loss. [P W I]
The repairs described in pages 168-175 would be technically impossible with the primitive facilities available. Faced with a similar situation, I would have attempted to transform the engine into a single-cylinder propulsion unit. It would have to be non-condensing if the air-pump was damaged beyond repair, or, alternatively, condensing, allowing the condensate (water) to drain to the bilges. I should reduce the boiler pressure to 30 lbs. per square inch (2.11 kg./cm²) and use salt water for boiler-feed.”
