S. A. Reilly, Our Legal Heritage : 600-1776 King Aethelbert - King George III
“ No coal trader or dealer may use his own lighters, barges, or other vessels to carry coals on the Thames River to and from any ship and to and from any wharf, dock, or creek because this has impaired the business of the watermen and wherrymen, whose vessels must now be registered and display such mark on their hulls. No lightermen nor buyers of coals may act as agent for any master or owner of a ship importing coals into London or forfeit 200 pounds, because this combination has caused the price of coal to go up. Selling one sort of coal for another is punishable by forfeiture of 500 pounds. ”
