Lewis Carroll subtitled the ‘Hunting of the Snark’ ‘an Agony in Eight Fits’. Those of you who want equivalent nonsense feel free to follow the link.
They hunted till darkness came on, but they found
Not a button, or feather, or mark,
By which they could tell that they stood on the ground
Where the Baker had met with the Snark.
In the midst of the word he was trying to say,
In the midst of his laughter and glee,
He had softly and suddenly vanished away — –
For the Snark was a Boojum, you see.
