O Friend-Betrayer at the Big Horn’s mouth,
Beware of someone riding from the South
To do the deed that he had lived to do!
Now when the sun stood hour-high in the blue,
From where a cloud of startled blackbirds rose
Down stream, a panic tumult broke the doze
Of windless morning. What unwelcome news
Embroiled the parliament of feathered shrews?
A boiling cloud against the sun they lower,
Flackering strepent; now a sooty shower,
