The third type of stoop has the same broad platform before the door, but the flight of steps is along the front of the house at one side rather than directly in front. While these were oftener straight, as in the case of the doorway at the northeast corner of Third and Pine streets, already referred to, they were frequently curved, as at Number 316 South Third Street. Both have a wrought-iron rail with the same scroll pattern of effective simplicity, a pattern much favored in modern adaptation. Another stoop of this type at Number 272 South American Street is high enough to permit a basement entrance beneath the platform. The ironwork is beautifully hand-wrought in the Florentine manner, its elaborate scroll pattern beneath an evolute spiral band combining round ball spindles with flat bent fillets, and the curved newel treatment at each side adding materially to the grace of the whole. The fourth type of stoop has double or wing flights each side of the platform before the door. The doorway at Number 301 South Seventh Street, already referred to, is the most notable instance of straight flights in Philadelphia, while that at the southeast corner of Eighth and Spruce streets occupies the same position in respect to curved flights. The wrought ironwork of the latter is superb. Rich in effect, yet essentially simple in design, it has grace in every line, is not too ornate and displays splendid workmanship. Again a spiral design is conspicuous in the stair balustrades, and the curved newel treatment recalls that of the foregoing stoop. The balustrade of the platform consists of a simple diaper pattern of intersecting arcs with the familiar evolute band above and below. The wing flight was a convenient arrangement for double houses, as instanced by the old Billmeyer house in Germantown, with its exceedingly plain iron handrail and straight spindles. Of more interest is the balustrade at Number 207 La Grange Alley with its evolute spiral band and slender ball spindles beneath. During the nineteenth century more attention was given to newels in ironwork, and elaborate square posts combining cast and wrought pieces were constructed, such as that at Fourth and Liberty streets. In the accompanying balustrade are to be seen motives much employed in the other examples here illustrated. Scroll work is conspicuous, as are rosettes, but a touch of individuality is given by a Grecian band instead of the more common evolute spiral above the diaper pattern. The pineapple, emblem of hospitality, was attractive in cast iron and as utilized at Number 1107 Walnut Street provided a distinctive newel.
