In the first entry in the popular Hazards of Helen series, Helen, the night telegraph operator at Lone Point, relieves Benton, the day operator, several hours ahead of time, because he is caring for his sick child. Receiving an order to sidetrack a freight until the fast mail passes, Helen mounts a horse, takes a short cut, leaps from a fifty foot cliff into a river, catches up with the freight, leaps aboard the locomotive, and gets the engineer to stop just in time to avert a horrible wreck.
