The story
“’The girl,’ daughter of Trapper Gates, is the only woman in a mining camp. The miners are well fixed, and three ruffians decide to rob them by strategy. So they visit the camp, and Bill, the leader, introducing himself as Professor Watson, announces that he will deliver a free lecture on a secret method of locating gold deposits. By this ruse he lures all the miners into the town hall and, aided by his two pals, easily holds up and ‘trims’ them. The girl’s father and sweetheart attend the lecture, but the girl is worried. It strikes her that there is something wrong about the entire affair. She goes to investigate, and finds that the miners are helpless and are being ‘cleaned out.’ There are no men in the camp to notify, as they are all at the lecture. The girl also realizes that, alone, she is unable to cope with three armed men. Suddenly she thinks of her father’s bear traps. She hastens home, gets them, and spreads them out on the steps of the town hall. The robbers back out, covering the crowd as she expected. They step into the bear traps and are easily captured, through the wit of ‘the only girl in camp.’”
