Glares burning, blinding, in the narrow street,
Still, noisome, deadly, sleeps the envenomed air,
Unstirred the yellow flag that says "Beware!"
Tempt not thy fate,--one little moment's breath
Bears on its viewless wing the seeds of death;
Thou at whose door the gilded chariots stand,
Whose dear-bought skill unclasps the miser's hand,
Turn from thy fatal quest, nor cast away
That life so precious; let a meaner prey
Feed the destroyer's hunger; live to bless
Those happier homes that need thy care no less!

Smiling he listens; has he then a charm
Whose magic virtues peril can disarm?
No safeguard his; no amulet he wears,
Too well he knows that Nature never spares
Her truest servant, powerless to defend
From her own weapons her unshrinking friend.
He dares the fate the bravest well might shun,
Nor asks reward save only Heaven's "Well done!"

Such are the toils, the perils that he knows,
Days without rest and nights without repose,
Yet all unheeded for the love he bears
His art, his kind, whose every grief he shares.

Harder than these to know how small the part
Nature's proud empire yields to striving Art;
How, as the tide that rolls around the sphere
Laughs at the mounds that delving arms uprear,--
