House-building, measuring, sawing the boards,
Blacksmithing, glass-blowing, nail-making, coopering, tin-roofing, shingle-dressing,
Ship-joining, dock-building, fish-curing, flagging of sidewalks by flaggers,
The pump, the pile-driver, the great derrick, the coal-kiln and brick-kiln,
Coal-mines and all that is down there, the lamps in the darkness, echoes, songs, what meditations…
–from Walt Whitman, ‘A Song for Occupations’
