The plans designed by Mr James Hislop for the exhibition conceit hall have been approved I hy the Building Committee, and tenders are now I being called for the erection of the hall. The building is to be situated at the corner of Cum berland and Gordon streets. The front portion of the hall will be approached by a broad cor ridor leading from the annexes in Cumberland street, and the back portion through a wide cor ridor from the annexes in Gordon street. The auditorium will be 108 ft long, 64ft 6in wide, and have a clear height from floor to ceiling of 50ft. At the back of the building will be the stage, raised 4ft 6in above the floor, and it will have a depth of 47ft_ 6in. The choir seats, which are to be circular in shape, will be arranged around the stage. They will be graduated, and will rise to a height of 10ft. A clear space 20ft in width will, however, be left in front of the choir for a platform. On each side of the platform there will be doors placed conveni ently near to the stage and communicating with the wide corridors, which will lead to the retir ing rooms. There will also be another door on one side of the building opening into the corri dor from the hall, which will give access to anyone wishing to get at the stage from the hall. The ladies' retiring room is to be 50ft long and 18ft in -width, and the gentlemen's of the same dimensions. Off the ladies' retiring room there will be lavatories, &c.; and, on the same side of the building, a room for storing musical instruments. On the opposite side, off the gentlemen's retiring room there will be a library tor keeping the music. The ceiling of the hall is to be circular in shape, and the walls aud ceil ings will all be close lined, with the grain of the wood running in the direction of the stage, this arrangement being resDrted to with the view of making the acoustic qualities of the building as good as possible. With the same object in view, the back of the choir wall and the ceiling will be carved out, and will meet the main wall without any break.
