"Moisture, I warrant, hitherto unquaffed

By boughs, however florid, wanting sap

Of prose-experience which provides the draught

"Which song-sprouts, wanting, wither: vain we tap

A youngling stem all green and immature;

Experience must secrete the stuff, our hap

"Will be to quench Man's thirst with, glad and sure

That fancy wells up through corrective fact:

Missing which test of truth, though flowers allure

"The goodman's eye with promise, soon the pact
