Lewis Carroll 
The Hunting of the Snark 

If-and the thing is wildly possible-the charge of writing nonsense were ever brought against the author of this brief but instructive poem, it would be based, I feel convinced, on the line (in p. 18)
'Then the bowsprit got mixed with the rudder sometimes.’
In view of this painful possibility, I will not (as I might) appeal indignantly to my other writings as a proof that I am incapable of such a deed: I will not (as I might) point to the strong moral purpose of this poem itself, to the arithmetical principles so cautiously inculcated in it, or to its noble teachings in Natural History-I will take the more prosaic course of simply explaining how it happened.
