'They sought it with thimbles, they sought it with care; They pursued it with forks and hope; They threatened its life with a railway share; They charmed it with smiles and soap'. Ever since Lewis Carroll's nonsense epic appeared in 1876, readers have joined his ten-man Snark-hunting crew and pursued the search with great enthusiasm. What are they hunting for? What is the Snark? Numerous theories have been proposed. Carroll himself provides a helpful preface to the poem and is recorded as having explained to one reader: 'In answer to your question, 'What did you mean the Snark was?' will you tell your friend that I meant that the Snark was a Boojum. I trust that she and you will now feel quite satisfied and happy'.This edition, previously published as "The Annotated Snark", reproduces the original illustrations by Henry Holiday, including the 'supressed' Boojum drawing. Martin Gardner provides an introduction, notes and bibliography, and an Appendix contains F. C. S. Schiller's "Commentary on the Snark" and J. A. Lyndon's "Fit the Seven-and-a-Halfth".
