| Description | Photographed are (left) William Blackburn, Dick Smith, a farmworker and right, Edward Blackburn. They were digging marl on Lord Derby's Coach Road. The marl would be spread onto the fields and worked into the land by teams of horses to improve the soil quality. The children would make shapes and figures out of the soft marl that fell from the carts, which they would then leave to harden in the sun |
