A short magazine article describing a visit to linen mills in Lisieux, France, on the Touques river, whose undershot water wheels drive the factories. It walks through the carding room, the hot, steamy wet-spinning room where operatives work in minimal clothing, and the later processes of reeling, drying, hanking and baling. It ends with an explanation of how the wet spinning system strengthens the thread by dissolving glutinous substances in the flax.
