56 UNITED STATES NATIONAL MUSEUM 



The wall bases, the architrave plinths of all door openings and 

 the base blocks under the columns and pilasters are of pink Ten- 

 nessee marble, 12 inches high, with a hone finish. The floor is of 

 the same material and finish. The field is constructed of tiles aver- 

 aging about 12^ by 25 inches in size, but is divided into a number 

 of sections by bordered panels carrying the lines of the bases of the 

 piers, and extending between the piers themselves and from them to 

 the corresponding pilasters and columns on the four walls. 



The cornice and ceiling finish, as in the vestibule, is entirely in 

 plaster but practically devoid of ornamental moldings or bands. 

 Where the double piers occur the treatment is recalled in the ceil- 

 ing by the presence of double plaster beams, the sofiits of which line 

 with the surrounding wall cornice, and which span the distance 

 between the piers and the corresponding pilasters on the north and 

 south walls. This treatment is repeated in single instead of double 

 form between all other detached piers or columns and their cor- 

 responding pilasters. In all respects the cornice members of these 

 beams conform to those of the surrounding walls, thus dividing the 

 entire ceiling into a number of panels. The end portions of the 

 room are treated with a slightly projecting cornice terminating at 

 the ceiling in a cove. In the central part of the room the cornice 

 carries the same lower moldings but, instead of finishing with a 

 cove, it has additional molded members which give a slightly more 

 elaborate effect. 



Outer door grilles. — The openings in the masonry of the pavilion 

 front are 8 feet 6 inches wide by 15 feet 4-| inches high, but the size 

 of the movable gate area is reduced to 6 feet by 11 feet. The gates, 

 which are of heavy cast-iron grille work, are in two leaves, each 3 

 feet wide, designed in five panels with a border band enclosing the 

 whole and similar bands between the panels. The space above the 

 gates is occupied by a grille transom conforming in part to the detail 

 of the gate design, with the addition of a conventionalized bison's 

 head in the middle. Grille borders 10 inches wide and a rope 

 motive trim or architrave occupy the space between the gates and 

 the masonry jambs, and this border also -carries across the tops of 

 the gates as a transom bar. All gates are supported at the top and 

 bottom on cone-bearing pivots. The free edge of both leaves of 

 each pair has heavy bronze top and bottom bolts countersunk in the 

 stile, so that either leaf may first be closed and secured for the 

 operation of a Yale prison lock placed within one of the ornamental 

 rosettes of each leaf. Each gate is provided with a lever handle 

 on each side, the two being joined together but not operating any 

 locking mechanism. The thresholds are of bronze, ^ inch thick, 

 with vertical cross ribs 1 inch deep underneath and spaced not 

 more than 2 feet apart; they have a scoriated surface.
