Yes, the DRY STONE WALL, no mortar, is quite a wonderful thing. a book
which shows actual pictures of how these walls are built, (each face
of the wall slopes to the center---hard to describe, easy to diagram)
would be the way to go. Mortar is comparatively recent in this scheme
of things; HUGE structures were made without it.

You mean - like pyramids?? I've climbed over some of the oldest known
pyramids down in central Mexico, and it'd be more than I'd want to tackle in a
week. ;-)
