1) The man responsible for the colliers working underground.
The responsibilities of the bottom man were underground and they required him to work in conjunction with the banksman and the ‘master’. The mine-owner Langdale Sunderland wrote a letter to his sons in 1671 in which he said that a master should keep a true bottom-man what wages soever he gives. Let the bottom-man come to him every week to give an account of every man’s work … to know a true bottom-man and banksman, you must observe, if the colliers love them you may swear safely they are knaves. The whole trust lies in the bottom man and banksman and only them .
