“Apples? New Hampshire has them, but unsprayed,
With no suspicion in stem end or blossom end
Of vitriol or arsenate of lead,
And so not good for anything but cider.”

Eagle with crest of red and gold,

Point for them the virtue of slaughter,
Make plain to them the excellence of killing
And a field where a thousand corpses lie.”
