*'Twas Euclid, and the constant pi*

Did plane and solid in the text;

All parallel were the radii,

And the ang-gulls convex'd.
"Beware the Wentworth-Smith, my son,

And the Loci that vacillate;

Beware the Axiom and shun

The spurious Postulate."

He took his Waterman in hand,

Long time the proper proof he sought--

Then rested he by the XYZ

And stood a while in thought.

And as in inverse thought he stood

A brilliant proof, in lines of flame,

All neat and trim, it came to him

Tangenting as it came.

"AB, CD," reflected he--

The Waterman went sicker-snack;

He Q.E.D.-ed, and, proud indeed,

He trapezoided back.

"And hast thou proved the 29th?

Come to my arms, my radius boy!

O good for you! O one point two!"

He rhombused in his joy.

'Twas Euclid, and the constant pi

Did plane and solid in the text;

All parallel were the radii,

And the ang-gulls convex'd.
