Some forty years ago the Jesuits obtained permission to build a church in the most fashionable quarter of London, a privilege that was obtained not without difficulties, and was subject to the condition that they should also take charge of a poor and impoverished chapel in the slums of Westminster. It was almost impossible to secure a suitable site in Mayfair or near Grosvenor Square, so the church was built in what is no more than a stable lane, then known as Berkeley Mews, at the back of Mount Street, but which has assumed the name and dignity of Farm Street. The church is a beautiful, well-designed Gothic building, built by Scholes, added to, and altered by Mr. Clutton. The _coup d’œil_, to one standing at the door, is striking and attractive, from the display of painted glass, which fills not only the great altar window, but all the clerestory, as well as from the rich garniture of the sanctuary. The sanctuary and chapel, close by, present a spectacle of costly enrichment, the walls being a mass of coloured marbles, deep green and mellow strawberry tint, encompassing elaborate mosaic pictures, and gilded carvings. There is a small arcade to the right which opens into the adjoining chapel: an organ picturesquely projects on the left; beneath are gilt grilles and gates, while the richly-carved altar, all pinnacles and niches and figures, fills the centre. The altar is the work of the elder Pugin, and is a fine specimen of his manner, suggesting much, but too crowded with details. The communion rails are his design also, the pulpit, we believe, is from the same “eminent hand.” The new organ is one of the richest and most powerful in London. CHAPTER XXV.
