p. 89: “The awkwardness of some snarks being boojums”, from Lewis Carroll’s poem, “The Hunting of the Snark”:
"Come, listen, my men, while I tell you again/The five unmistakable marks /By which you may know, wheresoever you go, /The warranted genuine Snarks.
"Let us take them in order. The first is the taste, /Which is meager and hollow, but crisp: /Like a coat that is rather too tight in the waist, /With a flavor of Will-o-the-wisp.
"Its habit of getting up late you’ll agree/ That it carries too far, when I say /That it frequently breakfasts at tea, /And dines on the following day.
"The third is its slowness in taking a jest. /Should you happen to venture on one, /It will sigh like a thing that is deeply distressed: /And it always looks grave at a pun.
"The fourth is its fondness for bathing-machines,/Which it constantly carries about,/ And believes that they add to the beauty of scenes- /A sentiment open to doubt.
"The fifth is ambition. It next will be right /To describe each particular batch: /Distinguishing those that have feathers, and bite, /And those that have whiskers, and scratch.
"For, although common Snarks do no manner of harm, /Yet, I feel it my duty to say, /Some are Boojums-" The Bellman broke off in alarm, /For the Baker had fainted away.”
