"I have the honor to say to your lordship, that your lordship must be aware of your lordship's important duty as a Minister to the United States, and I trust that your lordship will pay a little attention to your lordship's grammar when next your lordship addresses your lordship's most obedient servant.

The sun rushed up the eastern sky in a state of patriotic combustion, and as the dew fell upon the grassy hill-sides, the mountains lifted up their heads and were rather green. Far on the horizon six rainbows appeared, with an American Eagle at roost on the top one, and as the translucent pearl of the dawn shone between them, and a small pattern of blue sky with thirty-four stars broke out at one end, I saw--I beheld--yes, it ees! it ees! our Banger in the Skee yi!
