“Digital Documentation and Dissemination: You Got a Point Cloud, So What”

Presented by Michael G. Spencer

The creation of measured drawings, especially of historic barns, can be a tough sell; yet traditional methods are time-consuming, cumbersome, and costly. While newer, mass-capture methods such as laser scanning offer efficiency in some areas over more traditional methods the technology still presents problems, particularly in usability of data. This lecture will examine some other documentation alternatives such as photo rectification and photogrammetry as well as the variety of ways in which the data can be used and disseminated to assist in the preservation of agricultural structures such as barns, including recent documentation of a log tobacco barn on Booker T. Washington’s farm in southwest Virginia.

The image above was taken from a short video created by Professor Spencer with help from undergraduate students in the University of Mary Washington’s Department of Historic Preservation (link to video above).

Michael G. Spencer is Chair of the Department of Historic Preservation at the University of Mary Washington where he teaches courses that focus on architectural documentation and conservation. His research has involved the exploration of non-destructive technologies such as infrared thermography, as well as new methods of documenting historic structures and evaluation of new platforms for dissemination of that data. Recently this research has centered on photo rectification, photogrammetry, 3D modeling, and virtual reality.

November 3rd: “The English Barn: in America: an Introduction to its Layout and Carpentry”

Presenter: Jack A. Sobon

Common throughout most of the Northeastern United States, the English barn was the standard for barns from the earliest settlements up through the mid-nineteenth century.  Mr. Sobon will discuss its origins, its layout and use, and an in-depth look at its carpentry.  The intricacies of the older Scribe Rule system of timber layout and cutting brought here from Britain will be explained as well as the newer Square Rule method that replaced it.

Jack A. Sobon

Mr. Sobon is an architect and builder in Western Massachusetts that specializes in timber-framed buildings, both old and new.  Since the late 1970s, he has framed over 50 timber-framed structures using only traditional hand tools and often right from the forest.  He has four books to his credit including Historic American Timber Joinery (2002) and Hand Hewn, The Traditions, Tools, and Enduring Beauty of Timber Framing (2019).  He is also the author of a five-article series on The English Barn in America published in Timber Framing where he chronicles the construction of a classic three-bay English timber-framed barn using original construction methods.

“New England Barns & Farm Buildings”

Presenter: Thomas D. Visser

Keywords: New England Agriculture, Historic Barn Types, Historic Construction Methods and Materials, Barn and Outbuilding Terminology, Documentation

IIn 1997 Thomas Visser published his book, Field Guide to New England Barns and Farm Buildings based on his years of research documentation and site visits assisting owners with planning the preservation of historic farm buildings in the northeast region of the country. Although his book detailed historic farm buildings from just six states in the union, Visser’s work described construction methods, materials, and forms to provide a broader view of how the practice of agriculture shaped the appearance of barns and outbuildings throughout the country.

This presentation will discuss barn types and construction, as well as examine the ways in which farm buildings detail a rich rural heritage worthy of preservation. Building upon the information in his publication, the presentation will also highlight some of the many challenges barns and farm buildings face in the twenty-first century.

Thomas D. Visser, Professor of Historic Preservation, is the director of the graduate Historic Preservation Program in the Department of History at the University of Vermont. He has taught courses at UVM since 1985 on such topics as historic preservation planning and policy, researching historic buildings, architectural conservation, history of American building technology, and other historic preservation topics.

As a recipient of a National Endowment for the Arts grant award, much of Thomas Visser’s scholarly research has focused on the preservation of vernacular architecture. His award-winning Field Guide to New England Barns and Farm Buildings was published by the University Press of New England.

His latest book, Porches of North America, examines how this remarkable building feature in its many forms and uses has evolved in the United States and Canada. It is also published by the University Press of New England in hardcover and as an e-book.

“Historic Barns of Shenandoah County, Virginia”

Presenter: John Adamson

Keywords: Shenandoah Valley Agriculture, Historic Barn Types, Historic Construction Methods, Barn Terminology, County-level Survey/ Documentation

From 2017 until the present, Mr. Adamson has surveyed over 270 surviving barns in Shenandoah County. This program is a photo essay depicting barns of Shenandoah County built before 1950 and the agriculture those barns served.

Using the Shenandoah County Historical Society’s photographic archives, images of traditional agricultural scenes and practices from the 1910s and 1920s are followed by a description of the types of barns constructed in Shenandoah County from earliest settlement in the 18th century until approximately 1950.

Drawing on the photographic and data records of his survey work, Adamson’s program presents a rich pictorial review of the iconic barns still found in the county. It also includes a brief discussion of the cultural roots of Shenandoah County agriculture and barn architecture, presenting basic barn terminology and construction methods.

“Oklahoma’s Historic Barns”

Presenter: Dr. Brad Bays

Keywords: Barn Types, Upland South Culture, Native American Agriculture, Historic Construction Methods, Barn Survey, NRHP Evaluation, Criteria A and C

Historic barns in Oklahoma are disappearing for a variety of reasons, yet they serve as the most vivid, multigenerational markers of local landscapes, reminding us of the inevitability of economic, technological, environmental, and cultural changes which all places undergo.

Between 2009 and 2014, Brad Bays conducted a survey of the state’s historic barns for the Oklahoma State Historic Preservation Office and the Oklahoma Historical Society. The OK/SHPO’s objective was to document at least 10 historic barns in each county over the span of five years.

Five years later, Brad had logged around 55,000 miles, mostly on county roads, in each of the state’s 77 counties. He had visited more than 5,000 sites and documented just under 1,000 properties for the Oklahoma Landmarks Inventory (OLI), the state’s archive of properties that are National Register-eligible or warrant further study for possible NR listing. Of these, about 100 properties were deemed NR-eligible. The experience had taken him to every corner of every county in the state, and better awakened him to Oklahoma’s substantial diversity. This presentation will provide a geographical overview of the forms and materials of Oklahoma’s surviving historic barns.

The survey discovered rare types of barns not previously known to exist, as well as yet-unclassified types. Log barns of every type can be found throughout the former Indian Territory, and they reflect cultural ties to the Upland South and the effects of prolonged inaccessibility. Native stone and masonry barns are found clustered in pockets around the state, and bank barns tend to be associated with ethnic German settlement. 

Brad Bays is Associate Professor of Geography at Oklahoma State University. He holds a BA from Oklahoma State University (1989), an MS from the University of Tennessee-Knoxville (1991), and a PhD from the University of Nebraska-Lincoln (1996), all in Geography. He has been on the faculty at Oklahoma State University since 1995. His research and teaching interests center on the historical geography and agricultural history of the southern Great Plains, especially his home state of Oklahoma.
