8.--_The Tapiser's Puzzle._

The piece of tapestry had to be cut along the lines into three pieces so

as to fit together and form a perfect square, with the pattern properly

matched. It was also stipulated in effect that one of the three pieces

must be as small as possible. The illustration shows how to make the cuts

and how to put the pieces together, while one of the pieces contains only

twelve of the little squares.
