 * Stepping Stones
 * The diagram represents eight stepping-stones across a stream.

 * The puzzle is to start from the lower bank and land twice on the upper bank (stopping there),
 * having returned once to the lower bank.


 * But you must be careful to use each stepping-stone the same number of times.
 * In how few steps can you make the crossing?


 * Make the steps with two fingers in the diagram, and you will see what a very simple matter it is.
 * Yet it is more than likely that you will at first take a great many more steps than are necessary.
