Henry Holiday: The Snark’s Significance, 1898-01-29 (The Academy, p. 128)
It is possible that the author was half-consciously laying a trap, so readily did he take to the inventing of puzzles and things enigmatic; but to those whok new the man, or who have divined him correctly through his writings, the explanation is fairly simple.
Mr.Dodgson had a mathematical, a logical, and a philosophical mind; and when these qualities are united to a love of the grotesque, the resultant fancies are sure to have a quite peculiar charm, a charm so much the greater because its source is subtle and eludes all attempts to grasp it.
Attached to Holiday’s article there also is a letter from Carroll/Dodgson.
