Free hunting classics on project gutenberg
Project Gutenberg is a non profit making site which is making books available on line. They are all totally free. I am currently working through "In Africa" which follows a DG hunt in East Africa in 1910. Amongst other experiences the writer's safari meets up with a similarly engaged Teddy Roosevelt!

The Project Gutenberg eBook, In Africa, by John T. McCutcheon
I hope you enjoy it as much as I have. Wittily and well written it is illustrated with excellent monochrome photos and the author's own cartoons.
