I Hear America Singing
I hear American Mouth-Songs, the varied carols I hear;
Those of mechanics -- each one singing his, as it should be,
blithe and strong;
The carpenter singing his, as he measures his plank or beam,
The mason singing his, as he makes ready for work, or leaves
off work;
The boatman singing what belongs to him in his boat -- the
deckhand singing on the steamboat deck;
The shoemaker singing as he sits on his bench -- the hatter
singing as he stands;
The wood-cutter"s song -- the ploughboy"s, on his way in the
morning, or at the noon intermission, or at sundown;
The delicious singing of the mother -- or of the young wife at
work -- or of the girl sewing or washing -- Each singing
what belongs to her, and to none else;
The day what belongs to the day -- At night, the party of young
fellows, robust, friendly;
Singing, with open mouths, their strong melodious songs.
-- Walt Whitman, 1860
