Goes the type in his stick,
As the printer stands at his case;
His eyes glance quick, and his fingers pick
The type at a rapid pace;
And one by one, as the letters go,
Yet the type they look but leaden and dumb,
As he puts them in place with finger and thumb;
O, where is the man with such simple tools
Can govern the world as I?
—J. C. Pierce
