Mr William James Williams, known as Jim Tee, travelled through St Just, Botallack and Carnyorth selling fresh water from Nancherrow. His barrel held the equivalent of 5 'stans' (see my earlier posting in St Just and Pendeen album for an explanation of the standbarrow) which in turn was the equivalent of about 7 buckets of water.
He charged 6d for a barrel of water.
I have this from my mother's notes, I assume this was in the earlier part of the 20th Century. Mr Williams died in 1940.
