40.--_Lady Isabel's Casket._

The last puzzle was undoubtedly a hard nut, but perhaps difficulty does
not make a good puzzle any the less interesting when we are shown the
solution. The accompanying diagram indicates exactly how the top of Lady
Isabel de Fitzarnulph's casket was inlaid with square pieces of rare wood
(no two squares alike) and the strip of gold 10 inches by a quarter of an
inch. This is the only possible solution, and it is a singular fact
(though I cannot here show the subtle method of working) that the number,
sizes, and order of those squares are determined by the given dimensions
of the strip of gold, and the casket can have no other dimensions than 20
inches square. The number in a square indicates the length in inches of
the side of that square, so the accuracy of the answer can be checked
almost at a glance.

Sir Hugh de Fortibus made some general concluding remarks on the occasion
that are not altogether uninteresting to-day.

"Friends and retainers," he said, "if the strange offspring of my poor
wit about which we have held pleasant counsel to-night hath mayhap had
some small interest for ye, let these matters serve to call to mind the
lesson that our fleeting life is rounded and beset with enigmas. Whence
we came and whither we go be riddles, and albeit such as these we may
never bring within our understanding, yet there be many others with which
we and they that do come after us will ever strive for the answer.
Whether success do attend or do not attend our labour, it is well that we
make the attempt; for 'tis truly good and honourable to train the mind,
and the wit, and the fancy of man, for out of such doth issue all manner
of good in ways unforeseen for them that do come after us."

THE MERRY MONKS OF RIDDLEWELL

41.--_The Riddle of the Fish-pond._

Number the fish baskets in the illustration from 1 to 12 in the direction
that Brother Jonathan is seen to be going. Starting from 1, proceed as
follows, where "1 to 4" means, take the fish from basket No. 1 and
transfer it to basket No. 4:--

1 to 4, 5 to 8, 9 to 12, 3 to 6, 7 to 10, 11 to 2, and complete the last
revolution to 1, making three revolutions in all. Or you can proceed this
way:--

4 to 7, 8 to 11, 12 to 3, 2 to 5, 6 to 9, 10 to 1.

It is easy to solve in four revolutions, but the solutions in
