Why call a lady Blue? It is because

She reads, converses, studies for applause;

And therefore all that she desires to know

Is just as much as she can fairly show.

The real knowledge we in secret hide;

It is the counterfeit that makes our pride.

“A little knowledge is a dangerous thing”—

So sings the Poet, and so let him sing;

But, if from little learning danger rose, 50

I know not who in safety could repose.
