Recommendations for John Mason’s mansion

Recommendations for John Mason’s mansion

Memorandum providing recommendations for how to handle the ruins of John Mason’s mansion on Theodore Roosevelt Island. Stuart M. Barnette and O. F. Northington of the Historical American Buildings Survey recommend that a project be set up to further investigate the ruins. They cite the mansion as an important building in the development of U.S. architecture and provide a method for excavation based on the National Park Service. Barnette and Northington also recommend that a marker detailing the mansion’s place in history be placed near the site of the ruins. Accompanying these recommendations is a drawing depicting a conjecture of how the house may have appeared, a plan of the grounds showing the layout of all the buildings, and several photographs showing the ruins.

Mason House, Analostan Island, Washington DC: Photographs, written and historical data

Mason House, Analostan Island, Washington DC: Photographs, written and historical data

Begins with a brief history of the Mason family including how General John Mason became owner of the estate on Analostan Island, later Theodore Roosevelt Island. It continues with a discussion of the appearance of the mansion built by Mason as well the beauty of the island as taken from accounts by contemporaries collected by Charles Cochran. Following the history is an extensive survey of the burnt remains of mansion by Stuart M. Barnette, an architect in the Park Service working for the Historical American Building Survey. Using photographs, observations of the site, and architectural drawings made by himself, Barnette discusses how the mansion might have appeared during Mason’s occupancy and points out the Classical Revival influence in the temple structure of the buildings. Barnette systematically discusses every aspect of the estate describing every room and ancillary building. He particularly focuses on finding an explanation for the incongruous layout of the buildings since according to Classical Revival style the layout would be symmetrical.

Report of trip to Theodore Roosevelt National Memorial Park

Report of trip to Theodore Roosevelt National Memorial Park

Paul L. Beaubien reports on a trip he made to Theodore Roosevelt National Park to try to ascertain where the Elkhorn Ranch had been. He and Ray H. Mattison were able to approximate the location closely by comparing the terrain with photographs taken of the area by Theodore Roosevelt in 1886. While there is no evidence remaining on the surface, Beaubien believes that excavation in the area may reveal artifacts. Beaubien also describes a number of other visits he made to sites in the area, and includes photographs of the Elkhorn Ranch site.
