(Howbeit that puzzle never hurts the sale of it);

Thou chief of authors mystic and abstractical,

That lay their proper bodies on the shelf—

Keeping thyself so truly to thyself,

Thou secret fountain of a Scottish style,

That, like the Nile,

Hideth its source wherever it is bred,

But still keeps disemboguing

(Not disembroguing)
