59.--_Tasting the Plum Puddings._

"Everybody, as I suppose, knows well that the number of different

Christmas plum puddings that you taste will bring you the same number of

lucky days in the new year. One of the guests (and his name has escaped

my memory) brought with him a sheet of paper on which were drawn

sixty-four puddings, and he said the puzzle was an allegory of a sort,

and he intended to show how we might manage our pudding-tasting with as

much dispatch as possible." I fail to fully understand this fanciful and

rather overstrained view of the puzzle. But it would appear that the

puddings were arranged regularly, as I have shown them in the

illustration, and that to strike out a pudding was to indicate that it

had been duly tasted. You have simply to put the point of your pencil on

the pudding in the top corner, bearing a sprig of holly, and strike out

all the sixty-four puddings through their centres in twenty-one straight

strokes. You can go up or down or horizontally, but not diagonally or

obliquely; and you must never strike out a pudding twice, as that would

imply a second and unnecessary tasting of those indigestible dainties.

But the peculiar part of the thing is that you are required to taste the

pudding that is seen steaming hot at the end of your tenth stroke, and to

taste the one decked with holly in the bottom row the very last of all.
