"At night the artificial lighting is not less striking, a continuous row of gas jets following the outlines of the clerestory arches. A skilful arrangement of subsidiary lights destroys all shadows, and the effect is that of bright sunshine. An alternative system dispenses with the upper jets and substitutes a row at the level of the first gallery which is sufficient to give light to the ground area, when small meetings only are to be held. "With regard to ventilation, the plan selected seems most effectual. Every part of the building is under separate control, and there are numerous cunning little contrivances which are simple and not patented, but which do their work extremely well. "In an accoustical sense the hall is perfect. I am told that the flat panelled ceiling, which resembles in form that of the House of Commons, contributes to this result. "I was curious to know the truth of the assertion that from every seat, and there are four thousand three hundred, a view of the speaker upon the upper platform could be gained. I found it a fact. "Three prominent adjuncts of the hall remain to be described. The first is the great organ, containing 2178 speaking pipes, erected at the cost of £1000 by Messrs. Bevington & Son. The natural steel colour of the pipes has been preserved. It is a very fine instrument, and is not dwarfed or spoilt by the platforms in front of it, nor hidden in the recess which it fills. This shell-shaped alcove acts as a sounding board. "Over the great arch there are bas-reliefs representing groups of angels in the act of praise. From this arch falls the painted drop curtain, the subject of the picture thereon being the Feeding of the Five Thousand on the slopes of the Sea of Galilee. The curtain gives colour to the hall, and protects the organ when not in use. "Under the choir platform there is a large inquiry room, a part of which is partitioned off to provide space for a gas engine to work the great organ. "Another unusual feature is the octagonal Italian loggia or lobby, which intervenes between the frontage buildings and the hall. It is forty-four feet each way, by thirty-four feet high, and is lighted from the roof. The landings from two of the four great staircases, at each corner of the hall have exits into two galleries or balconies, looking down into the lobby. "The warming of the building is by an improved hot-air method, and the exits for use in case of fire are ample." The opening meeting, an occasion fraught with a significance that only Mr. Charrington and the thousands of friends who support his work can realise--for the outside world has known but little of the great work compared with its knowledge of other, and more largely advertised, agencies for good--was of an extraordinary character.
