The attic will have a French or Mansard roof, fifteen feet high above the crown moulding; and will be finished with an ornamental cornice and cresting of iron work. The tower, or central projection of the front, will be carried up fort3*-eight feet above the main cornice, and covered with a dome, in the Louvre st3'le, on which will be placed an open octagon belfry of fifteen feet diameter, terminating in an ogee domelet and vane, making the whole structure one hundred and seventy-five feet high above the sidewalk. The front of the building and the upper part of the tower will be of stone, and the side and rear walls of brick, finished with dressings of stone around all the openings. The dome and belfry will be constructed of iron, and the dome covered with copper. The belfry is intended to receive the Fire-Alarm Bell ; and the upper stories of the tower^aud the dome, are intended for the use of the Fire Department and Alarm Telegraph.

The main entrance to the building will be through an arcade, on the first floor, of three openings, six feet wide each ; this arcade forming a porch of fifteen feet deep by thirty-four feet wide. From this arcade we enter a main doorway, of six feet wide, lead- ing through a vestibule, twelve feet by sixteen feet deep into a central rectangle of thirty-six feet square. This rectangle will run up to the roof, having galleries, six feet wide, carried around, at each floor, from which doors will communi- cate with all the rooms, and be sur- mounted, at the roof, with a raised sky- light, that will be arranged to form a ventilator for the whole building. On the rear of the rectangle will be placed the stairway, twenty feet wide by twenty- nine feet deep, extending to the back wall of the building:, having large win- clows in each stoiy. The stairs will be built of stone ; and will have a central flight of eight feet wide, and two side flights of five feet each.
