- A full survey would cost about 1.5 million pounds (9 pence/acre for survey, 3 pence/acre for valuation).
- The maps would be at a scale of 26.7 inches/mile.
- Some large parishes required tens of square meters at this scale.
- Had all of England and Wales been mapped to this scale, the maps would have occupied 6.5 acres.
However, the figure of 6.5 acres does cast doubt on the remark that
... the tithe maps as envisioned by Jones and Dawson would allow a viewer to take in, with a single look, a complete understanding of the whole extent of the rural land of England and Wales.What can you tell with a single look over six and a half acres--acres of maps, that is, not of open country?
I don't especially mind doing the arithmetic. I do mind that the numbers seem to have been piled up to impress rather than to inform--else why not connect the numbers and provide some context?
I conclude by providing one piece of context gratis: the standard 7.5 minute quadrangle of the United States Geological Survey uses a scale of 1:24,000. Working out comparisons I leave as an exercise for the reader.
