Thank you to George T Smith, Canada, who wrote:
Barrels and Bungs
"The pictures in the cooperage
show workers using a 'flogger' to 'start' (open) the temporary bungs
made of cork. Hard bungs were hammered home using a cooper's adze
then shaved flush before going into the warehouses for maturing.
Hard bungs made pilferage
more difficult and being less porous reduced the 'angel's share'
during the years in bond. Cork bungs were not shaved so the canvas shows
in some photographs.
Some of the kit shown is after my
time. Casks were manhandled in the racking warehouse, not moved
mechanically down a filling line as shown in your picture."
