They are great finds. A blast from the past. I love the precision of the distance on the distance to Leeds - twelve and a quarter miles. I wonder if the chap went out with a tape measure. ha ha.
@onewing Thank you Babs for your interesting comment, well as to the measurements over two hundred years ago, William Smith became the first person to map the geology of the entire nation, not only was this scientifically significant, but in the process he produced rather beautiful maps:)
