Jack O'Connor
Warren Page
Robert Ruark
Corey Ford
Elmer Keith
Lucian Cary
Townsend Whelen
Charles Askins (the father)
E C Crossman
Julian S Hatcher
John Taylor
Theodore Roosevelt
Archibald Rutledge
C S Landis
John Hunter
Jim Corbett
A C Gould
Earl Naramore
Alexander Lake
... Burrard (first name escapes me)
... Greener (ditto)
Fred Ness
Al Barr
W H B Smith

It is my great and wonderful fortune that with the acquistion of Homer Powley's library, added to what I already had and what I've added lately, all but a very few of these greats' works are on my shelves -- available to all visitors, especially after we get the Powley Center built and open. By then, still more of these Golden Age books will be on these shelves. Ohh, (as Jackie Gleason used to say) how sweet it is! Great reading, both for pleasure and for learning about guns, shooting, hunting, etc.
