You get the strangest questions when walking about kilted....

A gentleman stopped me the other day. He began with the old "I see you are interested in Scots heritage...." preamble. To make a very long story short --

He has property here in western NC with the foundations of a very old grist mill (1700's) built by one of his ancestors who emigrated from Scotland. The foundation, rather than stacks of rocks in the corners or solid walls that would have supported the floor, is a solid, rectanguar platform approximately 12 x 25 feet. I would have been a monumental task to move that many large rocks into this pattern, so he is wondering if this is some kind of traditional construction method back in Scotland. He's searched and found nothing to verify or refute this hypothesis. I suggested that perhaps he had no saw mill to produce lumbrer for the flooring, but that seems unlikely as had been other buildings of the same vintage built of sawn lumber.

Any ideas?
