Then draw from X and Y to A
Two lines; then it is safe to say
That line A X and line A Y
Equal A B, being radii
Of the same circle, as you see
(According to geometry).
But since at first we did agree
A B your length of leg should be,
These, being equal to A B,
Are just the same as legs, you see.
So now on legs A X, A Y.
You stand upon the ground D I,
And drink your fill; for, as I said,
D I is touched by R, your head.
Thus we have proved—”
What happened here
Professor Pikestaffe has no clear
Impression, but the little row
Of stars above will serve to show
What madly reeled before his eyes,
As he went whirling to the skies.
Below he heard a mocking laugh,
That seemed to come from the Giraffe:
“Go up! go up! You’ve proved enough;
You’ve proved geometry is stuff!
You’ve proved, till I am well nigh dead,
And feel a thumping in my head,
That I must spread my feet apart
To take a drink—why, bless your heart!
I knew that long ere you were born.
I laugh geometry to scorn.”
Professor Pikestaffe, Ph. D.,
They say, has dropped geometry—
It seems he dropped his slate as well,
Which lies exactly where it fell
(Also the diagram he drew)
Upon the plains of Timbuctoo.
