sank the Garth pit and erected coke-ovens, which they worked until the depression in 1877 forced their closure. Richards (1982) says (re Garth Colliery, 1864), "J. Brogden & Sons bought Garth Fach and Cwmdu Canol Farms and sank this pit in 1865. The sinking operations were supervised by James Barrow, who was later President of the South Wales Institute of Engineers. He was also mineral agent to the Margam Estate. In 1867 there was an explosion but no-one was hurt. It resulted in the closure of the colliery for a year. About 1880 the pit was idle for another year but in 1882 it was sunk to a depth of 250 yards, 3 seams being worked. In addition there were 60 coke ovens producing 1,000 tons of coke weekly. It was after the sinking of Oakwood and Garth Pits that the village of Garth developed. Garth Pit closed in 1930 when it employed 616 men.". Ogmore Valley / Cwm Ogwr The Brogdens also worked the Ogmore valley, first at the top of the valley but in 1865 they sank the Wyndham pit and opened the Tynewydd level. They worked both of these until 1872 when a new joint stock company was formed. In July 1863 they obtained an Act for the Ogmore Valley Railway of which Alexander became the chairman. This was a standard-gauge railway from Nantymoel at the head of the valley to a junction with the Llynvi Valley Railway (Broad gauge) at Tondu. They also gained power to lay a third rail along the Llynvi Valley line from Tondu to Porthcawl. Aberdare The Bwllfa Dare No. 1 Pit was opened in 1856 by E Lewis and worked by the Byllfa Colliery Co. Ltd., then Brogdens and then the Bwllfa and Merthyr Dare Steam Coal Collieries Ltd. There seem to have been two Bwllfa and Merthyr Dare companies. The first was founded in November 1876 to purchase the lease from Brogdens. George, the only Brogden son not to be a partner in John Brogden and Sons, was connected with this first Bwllfa-Merthyr company. It seems to have been reorganised in 1881. On 17 April 1890 a meeting was held at the pit head, attended by about 700 colliers, at which George was presented with an illuminated address and described as the proprietor. Porthcawl The decision to build standard gauge in a broad gauge area prevented them from sending their
