212.--THE BURMESE PLANTATION.

[Illustration]

A short time ago I received an interesting communication from the

British chaplain at Meiktila, Upper Burma, in which my correspondent

informed me that he had found some amusement on board ship on his way

out in trying to solve this little poser.

If he has a plantation of forty-nine trees, planted in the form of a

square as shown in the accompanying illustration, he wishes to know how

he may cut down twenty-seven of the trees so that the twenty-two left

standing shall form as many rows as possible with four trees in every

row.

Of course there may not be more than four trees in any row.
