North Mississippi Commentor has a post up with many photos of an old dogtrot house. From that infallible source, Wikipedia:
A dogtrot house historically consisted of two log cabins connected by a breezeway or “dogtrot”, all under a common roof. Typically one cabin was used for cooking and dining while the other was used as a private living space, such as a bedroom.
From Tom’s post:
Its appeal for me is largely the degree to which it was a classic and did not seem to have been altered much over the years.
I don’t think it’s going to last much longer, sad to say.
