It was not a heart, beating.
That muted boom, that clangor
Far off, not blood in the ears
Drumming up and fever
To impose on the evening.
The noise came from outside:
A metal detonating
Native, evidently, to
These stilled suburbs nobody
Startled at it, though the sound
Shook the ground with its pounding.
It took root at my coming
Till the thudding source, exposed,
Confounded in wept guesswork:
Framed in windows of Main Street's
Silver factory, immense
Hammers hoisted, wheels turning,
Stalled, let fall their vertical
Tonnage of metal and wood;
Stunned in marrow. Men in white
Undershirts circled, tending
Without stop those greased machines,
Tending, without stop, the blunt
