From the Merthyr Telegraph, and General Advertiser for the Iron Districts of South Wales, 10 September 1870.

'PLYMOUTH COLLIERIES. In connection with the ironworks are six collieries yielding on an average 1,500 tons per day. There are at the South Dyffryn pits an immense pumping engine and a pair of gigantic moving engines of Cornish manufacture. These, for want of time, the visitors were unable to see on Tuesday. The collieries are under the management of Mr John Smith, one of the ablest, most successful, and least pretending of the many able mineral engineers of the district. Mr Smith is also manager of the extensive collieries of the Aberdare Iron Company in the Aberdare Valley.'
