This is probably the first accurate survey of the whole of Shropshire, including Broseley.  A detailed map of the Broseley Estate had been made in the 18th Century but this only covered the Eastern part of the town from the Parish Church to Jackfield.  The map shows coal pits at Caughley to the South East of Broseley.

  The map was produced in colour at a scale of 3 miles to 1"  and also in Black and White. It is much more detailed than Cary's map and shows features such as tramways running from Broseley to the Severn and also an Iron Foundry which was probably the Onions Foundry located in Foundry Lane.
