Of royal rank.
No. XXXV.—ON A BLACKBOARD
To test the powers of his young pupils, Dr Puzzlewitz set the following little problem on his blackboard:—
| A | - | B | = | 4 | ||
| A | ÷ | B | = | 4 | ||
What are the values of A and of B, when 4 is the result of dividing A by B, or of subtracting B from A?
20. RECAST
How great in olden days my power!
Oft have I saved a castle tower
From war’s invading tide.
Transpose me, and how great my fall!
I am then the smallest of the small,
That nothing can divide.
