333.--THE QUEEN'S JOURNEY.

[Illustration]

Place the queen on her own square, as shown in the illustration, and

then try to discover the greatest distance that she can travel over the

board in five queen's moves without passing over any square a second

time. Mark the queen's path on the board, and note carefully also that

she must never cross her own track. It seems simple enough, but the

reader may find that he has tripped.
