The Spider holds a Silver Ball

The Spider holds a Silver Ball
In unperceived Hands --
And dancing softly to Himself
Pursues his pearly strands --[^a1]His Yarn of Pearl -- unwinds --

He plies from Nought to Nought --
In unsubstantial Trade --
Supplants our Tapestries with His --
In half the period --

An Hour to rear supreme
His Theories[^a2]Continents of Light --
Then perish by[^a3]dangle from the Housewife's Broom --
His Sophistries --[^a4]Boundaries -- forgot --
