Today for #MinCup23 I'm voting ammineite because guano mineral 😆 I got no folklore for it, even though I vaguely remember reading a bat guano folktale at some point... couldn't locate it. Maybe for the next round.
While three men (George S. Key, Henry Jones, and Edward Smith) were initially sentenced to death for murder, their supporters launched a legal challenge to the Guano Act and the jurisdiction of U.S. courts, argued as Jones vs. U.S. before the U.S. Supreme Court and, when that failed, successfully lobbied President Benjamin Harrison to commute the sentences. By that point, the case had achieved such notoriety that he devoted part of his 1891 State of the Union address to defending his decision.
This support came principally from the Black Baltimore community - especially the Grand United Order of Galilean Fishermen and the Mutual United Brotherhood of Liberty.
While successful in saving the men's lives, the commutation of their death sentences to life in prison meant that Key, Jones, and Smith would spend the rest of their lives in hard labor in brutal conditions without labor protections. Just as they had on Navassa.
