A local in 1913 recalled.
"I remember that once a month on Sunday afternoons, Dr. Price, the Baptist minister, used to baptise his recent converts in the Cynon River, alongside the iron bridge at the bottom of Commercial Street. I have seen as many as 25 or 30 converts, men and women, on the same afternoon. On these occasions the whole of the Baptist community used to meet at the chapel and march in procession through the streets with the converts, the men converts being attired in long black robes and the women in white. They marched through the streets from the chapel to the place of baptism singing hymns. As a matter of course, large crowds gathered on the river banks to witness the immersions."
The figures below show the start of this as the revival was just beginning.
By Mr T. Price, Feb. 20, two; March 13, seven; April 10th twenty-seven.
