OUTER AND COURT DOORS 



The doors at the north and south public entrances to the building 

 have already been described. Those at the three other entrances are 

 as follows : The opening into the ground story of the south pavilion 

 from the passageway under the main approach, measuring 6 feet wide 

 by 13 feet high, is provided with double doors, having a large glass 

 panel in each leaf, and a transom. The openings and doors at the 

 wagon entrances, of which there are two at the outer ends of both 

 the east and west wings, are identical in all respects. The openings 

 are 10 feet wide by 15 feet 10 inches high, and the doors are double- 

 leaved, entirely of wood, 2^ inches thick and paneled, the two lower 

 panels of one of the leaves on each side of the building being hinged 

 to form a wicket gate. The doors are pivoted at the jambs, top and 

 bottom. At the edge of the wagon platform inside of the northern 

 door of this series on the east side, a large hinged door screen in 

 four sections or leaves has been introduced, mainly to keep out the 

 dust from the coal which is delivered to the bunker in the driveway 

 at this place. It consists of wood framework covered with sheet 

 steel, fills the entire opening which is 15 feet 8 inches wide by 16 

 feet high, and is provided with a small wicket gate. 



In the three large openings in the court walls of the gTound story 

 finished to give access to the courts, the doors, which are glazed, cor- 

 respond with the windows in appearance and measure 10 feet 6^ 

 inches wide by 9 feet 6 inches high, having a transom above. They 

 are double-leaved, 2^ inches thick, and have wood frames and trims. 

 The bottom rails carry the sill line of the adjacent windows and 

 have horizontal panels. Above the rail each leaf is divided into 

 three vertical lights by muntins, the same divisions continuing 

 through above the transom bar. There is also a small glazed wood 

 door opening into the courts at the base of each stair tower. 



INSIDE DOORS 



While a great diversity exists among the doors provided for dif- 

 ferent parts of the building, the majority, being chiefly those con- 

 nected with the rooms in the ground and third stories, conform to a 

 common pattern and are of two sizes. Both steel and wood have been 

 employed in their construction, principally the former, and the doors 

 of this material have been distributed with reference to securing as 

 adequate fire protection as possible for the rooms individually and 

 for sections of the building. The doors not belonging to the common 

 loattem have mostly been designed to meet special requirements and
