It was not long before the hyaenodon's leg was suffi-ciently mendedto permit him to rise and hobble about on three legs. I shallnever forget with what intent in-terest I watched his first attempt.Close at my arm lay my pile of rocks. Slowly the beast came tohis three good feet. He stretched himself, lowered his head, andlapped water from the drinking-shell at his side, turned and lookedat me, and then hobbled off toward the cliffs.

Thrice he traversed the entire extent of our prison, seeking, Iimagine, a loop-hole for escape, but finding none he returned in mydirection. Slowly he came quite close to me, sniffed at my shoes,my puttees, my hands, and then limped off a few feet and lay downagain.

Now that he was able to get around, I sometimes was a little un-certain asto the wisdom of my impulsive mercy.

How could I sleep with that ferocious thing prowling about thenarrow confines of our prison?

Should I close my eyes it might be to open them again to the feel ofthose mighty jaws at my throat. To say the least, I occasionally was uncomfortable.

I have had too much experience with dumb beasts to bank fairlystrongly on any sense of gratitude which may be attributed to themby inexperienced sentimen-talists. I believe that some beastslove their masters, but I doubt fairly much if their affection isthe outcome of gratitude--a characteristic that is so rare as tobe only occasionally traceable in the seemingly unselfish acts ofman himself.
