The principal entrance is through a spacious octangular porch, the whole size of the tower, which is groined in imitation of stone. The entrance to the galleries and side-aisles is by the doors on the north and south sides of the church. The size of the church from the tower to the chancel, in the interior, is ninety-four feet long, and fifty-two wide, with galleries at the south and north sides and west end. The accommodation is for one thousand persons, of which three hundred seats are free and unappropriated. The ceiling above the nave is divided into square compartments, by bold ornamented beams, with bosses at the intersection, which are painted in imitation of oak. The side-aisles are groined in imitation of stone, having bosses at the intersection of the ribs, with corbels for the ribs to rise from. The pulpit, reading, and clerk's desks accord in style with the building, and are placed in the centre of the middle aisle, which is ten feet wide. A handsome stone font is placed in front of the west entrance. We cannot conclude this account without expressing our admiration of this beautiful specimen of modern architecture, which, although not free from defects, possesses architectural merit in a very high degree. The uniform correctness of style in the detail, the beautiful and finely-proportioned spire, the chaste and elegant tracery of the windows, the light ornamental buttresses and pinnacles, all combine to give a character to the building pleasing and satisfactory, and reflect great credit on the architects, Messrs. Woodhead and Hurst, of Doncaster. The building was consecrated by his Grace the Archbishop of York, on the 10th of September, 1829; and the church opened for divine service on the 1st of November following. The Rev. Henry Branson is appointed the first minister to this church; and the friends of the establishment will hear with satisfaction that, since the opening, the number of worshippers has increased by those who formerly attended the dissenting meeting-houses in the town and neighbourhood. A subscription has been raised for an organ, which is now building by Gray, of London. * * * * * MAGNA CHARTA ISLAND. (_To the Editor_.) An early and constant subscriber to the _Mirror_ is very much pleased with the view of _Magna Charta Island_, in No. 467; but there is something more attached to this spot than the Editor seems aware of. About half a mile from _Magna Charta Island_, on the right bank of the river, in the parish of Wyrardisbury, is a farm house, for many years past in the occupation of a family of the name of "Groome," as tenants to the late Alderman Gill, holding an estate in the aforesaid parish. This farm house was a residence of _King John, whose arms_ are beautifully, painted, or emblazoned, on stained glass in the windows of the house.
