equal size. The lintels of the second floor windows are made of stone, while the windows on the third through fifth floors contain brick lintels with keystones made of stone. A brick entablature in the Doric order, and a stone cornice, runs above the stone trim on the fifth floor. The top 1.5 stories consist of a gambrel roof that includes the sixth-floor attic. Three brick-faced dormers protrude from the roof, corresponding to the architectural bays below; the dormers on the sides contain three windows, while the center dormer contains two windows. The tops of the original dormers included tablets with pediments, but S. Edison Gage added another row of roof-line dormers in 1913, These contain a similar articulation to the original dormers, though these are faced with terracotta instead of brick. A brick balustrade runs above the original brick dormers, just below the roof-line. An elevator shed and chimney are located behind the westernmost (leftmost) dormer. 18th Street The 18th Street facade is also divided into three layers of articulation, though the design is much simpler. This facade is divided into five bays, separated by slightly protruding brick pilasters. At ground level, the easternmost (leftmost) three bays contain large metal-frame windows, with grates covering the former window openings from the basement. The third bay also contains an emergency exit. The fourth bay contains a roll-down metal garage door and the fifth, westernmost bay contains a service entrance. There are small windows above the garage door and service entrance in the fourth and fifth bays. A stone cornice runs above the ground level. On the second through sixth floors, each bay contains three windows. The tops and bottoms of the rectangular second-floor windows contain stone trim. There are stone keystones atop the slightly arched third and fourth-floor windows, and atop the rectangular fifth and sixth-floor windows. A fire escape is mounted between the third and fourth bays, toward the western portion of this facade. A cornice, supported by stone bases that are attached to the vertical piers, runs along the facade between the fifth and sixth floors.
