Beware, ye Debtors! when ye walk, beware, Be circumspect; oft with insidious ken The caitiff eyes your steps aloof, and oft Lies perdue in a nook or gloomy cave, Prompt to enchant some inadvertent wretch With his unhallowed touch. So (poets sing) Grimalkin, to domestic vermin sworn An everlasting foe, with watchful eye Lies nightly brooding o'er a chinky gap, Protending her fell claws, to thoughtless mice Sure ruin. So her disembowelled web Arachne, in a hall or kitchen, spreads Obvious to vagrant flies: she secret stands Within her woven cell; the humming prey, Regardless of their fate, rush on the toils Inextricable, nor will aught avail Their arts, or arms, or shapes of lovely hue; The wasp insidious, and the buzzing drone, And butterfly, proud of expanded wings Distinct with gold, entangled in her snares, Useless resistance make: with eager strides, She towering flies to her expected spoils; Then, with envenomed jaws, the vital blood Drinks of reluctant foes, and to her cave Their bulky carcasses triumphant drags. So pass my days. But, when nocturnal shades This world envelop, and the inclement air Persuades men to repel benumbing frosts With pleasant wines, and crackling blaze of wood; Me lonely sitting, nor the glimmering light Of make-weight candle, nor the joyous talk Of loving friend, delights; distressed, forlorn, Amidst the horrors of the tedious night, Darkling I sigh, and feed with dismal thoughts My anxious mind; or sometimes mournful verse Indite, and sing of groves and myrtle shades, Or desperate lady near a purling stream, Or lover pendent on a willow-tree. Meanwhile I labour with eternal drought, And restless wish, and rave; my parched throat Finds no relief, nor heavy eyes repose: But if a slumber haply does invade My weary limbs, my fancy's still awake, Thoughtful of drink, and, eager, in a dream, Tipples imaginary pots of ale, In vain; awake I find the settled thirst Still gnawing, and the pleasant phantom curse.
