Hundreds have seen and heard Mr Evan Roberts to-day who were unable to gain admittance to the revival meetings on Sunday, and the wave is still rolling on with mighty vigour, while the news pouring in from all sources shows that the converts in different places in the Rhondda and Pontypridd during Sunday must have numbered hundreds. I understand there were forty converts at the Cymmer Independent Chapel on Sunday; that there were numbers at Salem (Baptist); at the hall of the English Baptists, and elsewhere in Porth; while from Pontypridd I hear of 28 at the Welsh Baptist Tabernacle, 60 at the Porth Primitive Methodist Chapel, twelve at the People’s hall, nine at the Town-hall (English Baptist), and eight at Calvary, Treforest, and that at Ynysybwl the converts up to the present time number upwards of 400, The “lists” are not yet properly collated in regard to Mr Evan Roberts’s meetings at Porth, but, the “flowing tide” is in the same direction everywhere. I hear that at Treharris there was a great meeting in the "Square” on Saturday night and that men who had been in public-houses were induced to go to the meetings in the chapels afterwards, and many of them were sobered and converted.

I could only find one source on the web as to where the PM church was and this is it. Whether it is or not does not really matter because there would have been revival here anyway.
