Henry Ernest Dudeney/Modern Puzzles/191 - Crossing the Ferry

by : $191$

 * Crossing the Ferry
 * Six persons, all related, have to cross a river in a small boat that will only hold two.
 * Mr. Webster, who had to plan the little affair, had quarrelled with his father-in-law and his son,
 * and, I am sorry to say, Mrs. Webster was not on speaking terms with her mother or her daugther-in-law.
 * In fact, the relations were so strained that it was not safe to permit any of the belligerents to pass over together
 * or to remain together on the same side of the river.
 * And to prevent further discord, no man was to be left with two women or two men with three women.
 * How are they to perform the feat in the fewest possible crossings?
 * No tricks, such as making use of a rope or current, or swimming across, are allowed.
