I first read "Man-Eaters of Kumaon" some 50 years ago and I still make a point of rereading his account of his old hunting companion, his dog Robin. And I still am deeply moved by the last paragraph in the chapter. "I have told you the story, and while I have been telling it Robin - the biggest-hearted and the most faithful friend man ever had - has gone to the Happy Hunting Ground, where I know I shall find him waiting for me." I still have that same volume and I wouldn't sell it for any amount, because I first read that story from that book with my dad when I was 8 years old.
I recently read it. (I found a first-edition copy in a used book shop, regulated to the discard room, and I snatched it up for a dollar, knowing it was magic before I even cracked the cover.) I thought one of the most moving scenes was one in which he killed the tiger in its sleep. I wonder if that caliber of man even exists anymore.
