|Plough deep while sluggards sleep.|
Benjamin Franklin.Poor Richard.
|Wherever a ship ploughs the sea, or a plough furrows the field; wherever a mine yields its treasure; wherever a ship or a railroad train carries freights to market; wherever the smoke of the furnace rises, or the clang of the loom resounds; even in the lonely garret where the seamstress plies her busy needle,there is industry.|
James A. Garfield.House of Representatives, April 1, 1870.
