Library of Congress: United States, Virginia, Loudoun County Middleburg - "Foxcroft School" by Francis Benjamin Johnston, ca. 1930 - https://www.loc.gov/item/2017890800/
NOTES: Porch House
“The frame building for the smallest girls is The Porch; The Wing, hitched to it at one end, is next oldest...The Porch is still in pigtails. The first year at Foxcroft, new girls were made to wear one pigtail; the next year two, and so on. After the school had been going ten years, the pigtail problem grew acute for little girls with bobbed hair, who simply didn’t have enough material to work with. As a result, pigtails now go in rotation, increasing one in number every year until one unfortunate class has to wear ten, after which the next batch reverts to one. This year, The Porch will appear in two only; and, as always, with their clothes on inside out during initiations (the first week of school).” Fortune Class, 1931
