“ There are many large slate quarries in this parish, especially at Blaenau Festiniog, the junction of three railways, London & North Western, Great Western and Festiniog, a narrow-gauge line between Portmadoc and Duffws. This light railway runs at a considerable elevation (some 700 ft.) , commanding a view across the valley and lake of Tan y Bwlch. Lord Lyttelton’s letter to Mr Bower is a well-known panegyric on Festiniog. Thousands of workmen are employed in the slate quarries. ”
