- Crossing the River
- During the Turkish stampede in Thrace, a small detachment found itself confronted by a wide and deep river.
- However, they discovered a boat in which two children were rowing about.
- It was so small that it would only carry the two children, or one grown up person.
- How did the officer get himself and his $357$ soldiers across the river and leave the two children finally in joint possession of their boat?
- And how many times need the boat pass from shore to shore?
