@Lordyaswas,
Good story, that.
And they're still using barges on the Thames...I was near River Street, quite near Millennium Bridge and therefore St Paul's, watching some rubbish containers being loaded into one, last year.
I often think on the changes wrought in the great ports (London, Liverpool, Glasgow, Belfast) by containerisation.
There is a marvellous documentary "The Box the Changed the World" which is well worth seeking out.
The days of dock labour...I notice that the docks in Liverpool have a very high wall around; probably very necessary. There was a story of a Liverpool docker called Diesel. As in, "Dese'll do the missus.... dese'll do di daughter."
The first
ever consignment of Scotch whisky to reach America intact, was the first one sent sealed in containers.
