321.—­THE ROOK’S JOURNEY.

This puzzle I call “The Rook’s Journey,” because the word “tour” (derived from a turner’s wheel) implies that we return to the point from which we set out, and we do not do this in the present case.  We should not be satisfied with a personally conducted holiday tour that ended by leaving us, say, in the middle of the Sahara.  The rook here makes twenty-one moves, in the course of which journey it visits every square of the board once and only once, stopping at the square marked 10 at the end of its tenth move, and ending at the square marked 21.  Two consecutive moves cannot be made in the same direction—­that is to say, you must make a turn after every move.
