Bend but those eyes now, using mind's eye too,

And note—sufficient for all purposes—

The ground-plan—map you long have yearned for—yes,

Make out in markings—more what artist can?—

Goethe's Estate in Weimar,—just a plan!

A is the House, and B the Garden-gate,

And C the Grass-plot—you 've the whole estate

Letter by letter, down to Y the Pond,

And Z the Pigsty. Do you look beyond

The algebraic signs, and captions say
