I've read it and enjoyed it. Another book, focusing more specifically on stone walls has Tom's recommendation (by blurb, anyway).

It would be great if you could get Tom Wessels to speak to the topic. The NHPR podcast Something Wild briefly addressed the topic a few years ago, and quoted him then https://www.nhpr.org/something-wild/2015-01-02/something-wild-stonewalls-as-landscape
