The Sheepbridge Company had in operation four pits as mentioned at Norwood, Dunston, Nesfield and Sheepbridge on the works but it was a need for more coal as there had been an upturn in the demand for local coal and therefore greater profits sought for the company that made them sink Langwith 1876-1880 and Glapwell *Collieries on an 84 year lease at a price of £30 per foot per acre and a minimum reserved rent of £4,000 with a surrender clause after 15 years. Leases that were extended and revised as the operations progressed. The 1833 Portland lease was for a 40 year term at £15 per foot thickness per acre under copyhold land and £40 per foot per acre under Whaley Moor with a minimum rent of £700 per annum. Allowances were made for faults and inferior coals if met. The pit initially cost £46,000 and was capable of producing 500 tons of coal per week.
*One item worthy of note is that the productivity at Langwith may have been at the expense of the ponies: a total of 163 at the four collieries in 1883. Norwood 56, Nesfield 25, Dunston 44 and Langwith 38. Ponies having a life of five years at all the pits other than Langwith whose average was only half that, two and a half years.

The colliery closed around 1980 and I was privileged to do my underground training there just prior to it closing in 1979. The shafts were kept pumping to prevent Creswell Colliery from flooding.
