Continuing on yesterday's theme, I have to ask why certain dry stone wallers in the U.S. and Canada (the ones who are confident using gas-saws, grinders, points and chisels as well as hammers) still need to position their smartly trimmed squarish throughstones so that they hang out over both sides of their walls? If they can fit every other stone flush along rows of straight coursing in their tidy dry stone creations, why not line the throughstones up along the plane of the wall too? Does the fact that we need to see all these protruding throughstones signify something else perhaps?
