Caslon or Garamond or Baskerville is shouted as the compositors search for as many cases of these types as can be found. But never is there enough of those metal letters. The apprentice is charged to clean the ones just used so he can distribute a constant supply, lest a compositor be forced into some fancy spelling for the want of Es. With his uppercase upper and his lowercase lower, the compositor, standing at his frame with his stick held in his hand, like an artist with his palette, looks first to the handwritten copy, before click, click, clicking metal letters into a line. Then, line by line, each page is built up upon a form and the metal words are banged home with a mallet, tightened and spaced with slugs of wood, then locked within this frame by the teeth of quoins. And when the page is set, 'Proof" is yelled at the door.
