After reading Henry Davis personal hunting diary I'm not sure if he was an authority on turkey hunting or a lawyer that that was an authority on writing....I lean towards the later.

Henry Davis wrote another book "Hunting with a .22" thats a really good read and has pictures of his custom rifles

No doubt the Henry Davis turkey book published in 1949 borrowed heavily in the way of turkey knowledge from this earlier 1914 book.

The Wild Turkey and Its Hunting” by E. A. McIlhenny.

This was the first book ever written on the sport and the tale of how it came to be reads like a murder mystery. While McIlhenny’s name appears on the title page, almost all the book was written by Charles L. Jordan a gamewarden that was killed by a poacher.

I believe he was shot in the back.
