That a serious error has crept in somewhere into the returns, as respects the Principality, is obvious from this one fact. The number of sittings provided by the Church of England is stated to be 301,807, and the number of the worshipping population of the same church on the 31st of March, 1851, is stated to be 138,719. Now Mr. Mann shows that the proportion per cent. of attendants to sittings in the Established Church, throughout all England and Wales, is only thirty-three; whereas by the above showing, the proportion of attendants to sittings in Wales alone is 40 per cent. We venture to say, that no man competently acquainted with Wales, knowing, as every such man must know, the miserably meagre attendance at hundreds of churches in that country, would for an instant believe that the churches are occupied in the proportion of 40 per cent. of attendants to sittings. Let us, however, take the figures given to us in the census. The population of Wales, including Monmouthshire, in 1851, was 1,188,914. The total number of places of worship was 4,006, which was distributed thus: PLACES OF WORSHIP. Of the places of worship-- The Established Church furnished 1,180 Nonconformists 2,826 ----- 4,006 SITTINGS. Of the sittings (including estimates for defective return)-- Established Church furnished 301,897, or 30 per cent. Nonconformists 692,239, or 70 per cent. It appears thus, that the Church had provided sittings for only 25 per cent. of the population, while the Nonconformists had provided sittings for nearly 59 per cent. But how about attendance? According to Table B. of the Census of Religious Worship, the greatest number by very far of attendants at the services of the Established Church on the Census Sunday was in the morning. The number was 100,953. If we add one-fourth to this number for the absentees, we have 126,191, which represents 10·6 per cent., not quite one in nine of the population.
