That was the Old Man’s favorite song. “Blow Ye Trumpet.” Them Negroes was far away from the doings on the plaza where the Old Man was to hang, way out from it. But they sang it loud and clear….Blow ye trumpet blowBlow ye trumpet blow….You could hear their voices for a long way, seemed like they lifted up and carried all the way into the sky, lingering in the air long afterward. And up above the church, high above it, a strange black-and-white bird circled ‘round, looking for a tree to roost on, a bad tree, I expect, so he could alight upon it and get busy, so that it would someday fall and feed the others.
