The Monkey that Would not Kill by Henry Drummond

After a long journey over the mountains Donald reached his log cabin on the Silver Creek. The monkey, however, did not find quite so immediate a welcome as himself from Donald's wife. The only pet her children had ever seen before was a baby puma, which the miner had picked out of the stream one day in a half-drowned state. Donald had mistaken it for a kitten of some new brand, and it was not until some weeks later, when it sprang upon his little girl and buried his claws in her neck, that he realised what sort of plaything -- the puma is the lion of the Rocky Mountains -- he had introduced into his family. So Donald's wife was suspicious of pets, and when she saw the monkey she was sure it was another lion, and would not allow it to enter the door. But Gum had other ways of entering houses than by doors, and finally he was received as a lawful member of the family, for the simple reason that he could not be kept out. The new guest gave little trouble.

Most of the day the monkey spent with Donald at the mine. He went off with him when he went to work in the morning, and gambolled round him till he came home for supper.
