A mid-19th century comparison of making paper by hand and by machine, stating that a single Fourdrinier machine as refined by Donkin and Dickinson, made roughly twenty times as much paper as could made by an individual papermaker working by hand. The device in the upper right corner is a Hollander beater used to grind up rag fragments into "stuff" that was the basis of paper made either by hand or by machine. (When I purchased this image the book in which it was originally published was not identified.)
