240.--THE UNION JACK.

From Amusements in Mathematics by Henry Ernest Dudeney.

[Illustration]

The illustration is a rough sketch somewhat resembling the British flag, the Union Jack. It is not possible to draw the whole of it without lifting the pencil from the paper or going over the same line twice. The puzzle is to find out just _how much_ of the drawing it is possible to make without lifting your pencil or going twice over the same line. Take your pencil and see what is the best you can do.
