Anybody wanting to delve deeper into the Kilner Providence Glassworks at Thornhill Lees, particularly with regard to industrial relations, could do much worse than consult the local newspapers (Dewsbury Reporter, Batley Reporter, Huddersfield Chronicle et al) from the period 1874-1880. There were some right goings-on, including a big "scab workers" scandal that saw black-legs bussed in from Sunderland that resulted in pitched battles in the streets. It explains why the 1881 census for Thornhill Lees shows a significant number of inhabitants with origins in the north-east when, ten years previously, there was nary a Mackem to be had.
