in both upper and lower sashes predominated. Six, nine and
twelve-paned sashes forming twelve, eighteen and twenty-four paned
windows were all common throughout the Colonial period. Twelve-paned
sashes were used chiefly in public buildings and the larger private
mansions, six-paned sashes in houses of moderate size. While there are
several notable instances of nine-paned upper and lower sashes,
particularly Hope Lodge, Cedar Grove in Harrowgate, Northern Liberties,
and the Wharton house at Number 336 Spruce Street, this arrangement
frequently, although not always, resulted in a window rather too high
and narrow to be pleasing in proportion. A comparison of the
accompanying photographs of the window of a Combes Alley house with that
of a house at Number 128 Race Street well illustrates the point.
Sometimes, where used on the lower story, six-paned upper and lower
sashes are found in the windows of the second story.

Waynesborough, in Easttown Township, Chester County, not far from
Philadelphia, is a well-known case in point. Grumblethorpe presents the
anomalous reverse arrangement of six-paned sashes on the first story and
nine-paned sashes on the second story. Still oftener six-and nine-paned
sashes were combined in the same window, the larger sash being sometimes
the upper and again the lower. Bartram House and the Johnson house are
instances of nine-paned upper and lower sashes on the first story and
nine-paned lower and six-paned upper sashes on the second story. Greame
Park in Horsham, Montgomery County, not far from Philadelphia, has
nine-paned upper and lower sashes on the lower story and twelve-paned
lower and nine-paned upper on the second floor. Penn's house in
Fairmount Park and Glen Fern are instances of nine-paned lower and
six-paned upper sashes on the first story and six-paned upper and lower
sashes on the second story. Solitude and the Blackwell house, Number 224
Pine Street, exemplify the reverse arrangement of nine-paned upper and
six-paned lower sashes on both stories.

Six-paned upper and lower sashes on both the first and second floors
were, perhaps, more common on houses of moderate size and some large
mansions throughout the Colonial period than any other window
arrangement. Notable instances are The Highlands; Upsala; Vernon;
Wynnestay in Wynnefield, West Philadelphia; Carlton in Germantown; the
Powell house, Number 244 South Third Street; the Evans house, Number 322
De Lancy Street; and the Wist
