Until lately, Aberavon was a mere village; but has recently increased rapidly, from the extension of the mines of coal and iron in its vicinity, and the establishment of extensive works for the smelting of copper and zinc. At Port Talbot, about a mile distant, is an excellent float dock, much frequented by numerous coasting vessels. It unites with Swansea in returning a member to parliament.
