With staff in hand across the cleft + 

The Challenger began his march; + 

And now, all eyes and feet, hath gained + 

The middle of the arch. + 

When list! he hears a piteous moan⁠— + 

Again!⁠—his heart within him dies⁠— + 

His pulse is stopped, his breath is lost, + 

He totters, pale as any ghost, + 

And, looking down, he spies + 

A Lamb, that in the pool is pent + 

Within that black and frightful Rent. + 
