Nice job collecting the data, but paper could have benefited from a map of the towns with a legend that shows the orientation of the towns.

The author discusses clusters of towns with orientations, but as a non-subject matter expert I struggled to follow the trends that may be suggested.

Paper is also incomplete in that the table on the final page doesn't have headings. I hope the published version in 2008 had it, but it's under-paywall and doesn't appear on the Authors webpage.
