I don't recall which of his books it is, but I still like the part where Bell describes the natives' somewhat unusual behavior.... He would set up camp near a village and befriend the natives. When he would go out to hunt, anything he left behind - no matter how well hidden and/or locked up - would be stolen immediately by the villagers. It wasn't something they did with any malice - they just took it all. This got very frustrating until he figured out that he could simply leave everything unsecured and it would all be there when he returned. The difference? He would entrust the care of the goods to one of the natives. Having done so, no one would touch them.
