Excerpt from Two Related Industries: An Account of Paper-Making and of Paper-Makers Felts as Manufactured at the Kenwood Mills, Rensselaer, New York, and Arnprior, Ontario, Canada, the Two Plants of F. C. Huyck Sons, Albany, New York

It may safely be said that the product of every industry in dependent on the product of some other industry either as a raw material or as a necessary supply in the process of manufacture. The great industry of paper-making has always been dependent on the product which has been known as paper-makers' felts.

From the time when the artisan making paper by hand laid a square piece of woolen cloth over the sheet of paper formed on his frame, and was able by the peculiar properties of the wool fibre to lift the sheet of paper attached to the cloth and transfer it to the pile where by hydraulic pressure the water was removed, to the present where the great endless felts of woolen cloth carry the rapidly moving, continuous sheet of paper through the various press-rolls of the paper-machine at tremendous speed, nothing has been found but this woolen cloth - always known as paper-makers' felts - that would serve this essential purpose. It is not a felt in the true sense of the word, because felt, as it has been made for thousands of years, consisted of the wool fibres pressed and felted or fulled together by the peculiar, half-mysterious tendency of the fibres to interlock, working so closely together that a strong fabric was formed.

The Scythians, who from remotest antiquity roamed about the wastes of Northern Asia, as did their successors, the Tartars, used felt for clothing and tent-coverings; and to-day in parts of Asia the same felted woolen fabric is used for the same purpose.
