Overhanging Plates, Again

I've penned a few posts about the mysterious overhanging plate, which, though common in the Upper South and Midwest, remains largely unstudied. Last month, while idling in my college's library, I discovered an early (1952) mention of the overhanging plate in Hugh Morrison's Early American Architecture. On page 168, Morrison writes:

The topmost logs at the ends of the cabin were projected to carry the wall plate forward, thus offering a modicum of protection from rain to the lower wall.

This "cabin" (truly a log house of "saddlebag" plan) stood in Caldwell County, North Carolina, near Blowing Rock. In 1938, Frances Benjamin Johnston photographed the home, then inhabited by one Mrs. Mary Gregg, for her Carnegie Survey of Architecture of the South.

In Early American Architecture, Morrison suggests the overhanging plate exists to shelter walls from rain, a theory equally plausible as mine (that the overhanging plate evolved from the butting pole). Of course, neither conjecture is provable.

The Gregg residence's logs were unusually well-handled; if I knew no better, I'd describe them as "circular-sawed."

Note the steeple notching, closely-fitted logs, and overhanging plate. The chamfered side log is standard.
