 The building, austere in design, was 132 feet in length and 57 feet in width.The ground floor and first storey were each divided into 12 rooms; the second storey was fitted up for assembling the whole of the children for public worship, or on other occasions; having two tiers of windows, and a gallery on each side extending about half the length of the building.In order to aid both the hearing and sight in this long room, the floor rose in an inclined plane about half way.
