Advantage for who vaults from low to high

And makes the stumbling-block a stepping-stone?

So, Guido, born with appetite, lacks food:

Is poor, who yet could deftly play-off wealth:

Straitened, whose limbs are restless till at large.

He, as he eyes each outlet of the cirque

And narrow penfold for probation, pines

After the good things just outside its grate,

With less monition, fainter conscience-twitch,

Rarer instinctive qualm at the first feel
