'Twas well, O soul--'twas a good preparation you gave me,
Now we advance our latent and ampler hunger to fill,
Now we go forth to receive what the earth and the sea never gave us,
Not through the mighty woods we go, but through the mightier cities,
          for us is pouring now more than Niagara pouring,
Torrents of men, (sources and rills of the Northwest are you indeed
inexhaustible?
