Margot Matthew as running for her life. She was being chased by a group of cannibals after she had 'borrowed' two of their gold ingots. She had running for quite some time, carrying the metals, until she reached a rope bridge, which said that it would only hod 125 pounds.

Margot was already 110 pounds, and both ingots weighed 9 pounds each. She wasn't wearing any shoes or anything heavier than her body weight. There was time for two trips.

How did she make it across,and live to tell the tale?
