No.33 'Answers for George Ross and Others' (29 Jan 1774) in the court case against the bound colliers of Dryden Coalworks
Mainly restating relevant parts of evidence already given but includes this explanation of enrolling children as bound colliers -
"when children work with their parents up to after the age of consent, there is grounds for presuming they have bound themselves But this notwithstanding, some cerimonials are generaly if not constantly observed upon the part of the Coalmasters to insure to themselves the property of these young colliers and the general practice is that a boy or a girl enters to the work they receive a piece of money and their names are inrolled in what is called the on-cost book which likewise mentions their particular ages."
