Which can’t itself sustain,

Fall down! thy rocks may crush me flat;

Thy warning I disdain.”

And now down fell the pond’rous mass,

And roll’d along the cavern’s base,

Afar its fragments scatt’ring,

With awful din and clatt’ring!

And lo! exuding from the ground

A poisonous vapour grey,

Like billow, roll’d the hall around;
