Lines in a Flyleaf of "Christabel"

Inhospitably hast thou entertained,
O Poet, us the bidden to thy board,
Whom in mid-feast, and while our thousand mouths
Are one laudation of the festal cheer,
Thou from thy table dost dismiss, unfilled.
Yet loudlier thee than many a lavish host
We praise, and oftener thy repast half-served
Than many a stintless banquet, prodigally
Through satiate hours prolonged; nor praise less well
Because with tongues thou hast not cloyed, and lips
That mourn the parsimony of affluent souls,
And mix the lamentation with the laud.
