I forgot to mention in the main article that when Steam Mills on the Macclesfield canal exploded in 1881, that fortunately it was at night and the mill was not full of workers and so only one man was killed. Still a tragedy but not what may have been.
The explosion was front page news in the milling press of the day, according to Tony Bonson (The Midland Wind and Water Mills Group). The mill was also said to be one of the best organised in the United Kingdom, hopefully a legacy of the Swanwicks of Macclesfield and the Brindley's of Marple.
