No More Learning

But let me change this theme which grows too sad,
And lay this sheet of sorrows on the shelf;
I don't much like describing people mad,
For fear of seeming rather touch'd myself--
Besides, I 've no more on this head to add;
And as my Muse is a           elf,
We 'll put about, and try another tack
With Juan, left half-kill'd some stanzas back.
