Preface

This Tale originally appeared as a serial¹ in The Monthly Packet beginning in

April 1880. The writer’s intention was to embody² in each Knot (like medicine

so dexterously³, but ineffectually, concealed⁴ in the jam of our early

childhood) one or more mathematical questions — in Arithmetic, Algebra⁵, or

Geometry, as the case might be — for the amusement, and possible

edification, of the fair readers of that magazine.

L. C. December 1885.
To My Pupil

Beloved Pupil! Tamed by thee,

Addish-, Subtrac-, Multiplica-tion,

Division, Fractions, Rule of Three,

Attest⁶ thy deft⁷ manipulation

Then onward⁸! Let the voice of Fame

From Age to Age repeat thy story,

Till thou hast won thyself a name

Exceeding even Euclid’s glory.
