A Spider’s Skill!

How doth the little spider be,
A Master of Geometry?
Oh tell me, tell me, if you know,
Where did she learn to weave quite so?
Please tell me little Spider friend,
How many hours did you spend
Creating such a sight to see,
Such skillful lines of symmetry?
Concentric frame,
Installed at night,
A work of art,
By morning light!
