"Abercanaid & Pentre-bach. These places are populous districts on both sides of the river Taff near Merthyr. They are connected with the extensive works at Pentre-bach, where National schools have been established many years ago. Here again the Dissenters are obliged to submit to Church Catechism, and Church attendance. There is no public school on unsectarian principles, at Abercanaid, Pentre bach, or Troedyrhiw, in this neighbourhood although they have Dissenting Chapels numerous."
