One thing I have sometimes wondered about is the plane table method of surveying that the Swallows used, and accuracy they obtained. I don't know if any of you have tried plane-tabling for real, but it is not as easy as it looks!
I trained as a land surveyor and our first exercise was a very simple plane table survey of part of the university grounds. Even with a proper, leveled table and alidade we produced a map with some distinctly unsquare buildings and fudged lines to make them straight.
