Snark Taxonomy

"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 meagre and hollow, but crisp:
Like a coat that is rather too tight in the waist,
With a flavour 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 five-o'clock 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 frequently 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,
From 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.

-Lewis Carroll, The Hunting of the Snark
