Notes: For some reason, Kesteven or Kestavan or even Crosher are listed as author in various places. Definitely needs a LOT of verification! Price on front flap of archive.org copy; copyright page: "Copyright 1974 by G.R. Crosher"; biography on last unnumbered page says Crosher is author's real name; cover of this edition misspells last name as "Kestavan".
