Underpinning pit at the White House
Underpinning pit with cribbing along north wall of lower corridor (G-30) outside the Library. This is from a series of photographs of the renovation of the White House.
Niche in the northwest side of the Study (Room 21). In recent years, book shelves were installed in this niche and in the one opposite on the northeast side. Before 1902, photographs show windows in the niches. The ventilating duct, seen below, was probably in use at an earlier date. This is from a series of photographs of the renovation of the White House.
