Labourers working on the canal at Blue House Reach in the process of puddling or making the canal base watertight through the use of a clay mix. The canal was built in 1789 which was too early to be recorded by a photograph. However this image of the canal being restored to be reopened between 1900 and 1904 shows the techniques that would have been used.
