Only four articles on croc hunting are here for you. It as not a popular hunting venture in the 19402s-1970s so not many stories exist. "The Cautious Crocodile" by Warren Page is a good overview. "Having a Crack at Crocs" and "Africa's Maneating Monsters" also will give you an idea of what crocs do in Africa. "The Axe Men of Africa" is a story of natives killing crocs axes.
Africa is interesting in that it hold a value of human life different than here in the west. Women will draw water from a nearby river's still pool. Crocs know this and wait. When the woman puts her container in the water the croc will shoot forward, grab her, and drag her under in a split second. (Kind of like the first Crocodile Dundee but without the time for a struggle). Fellow villagers know of her fate when they follow her tracks to the water to search for her. The next day, another woman draws water from the same place.
