"One day, in my office, there was a hot discussion going on about the material that the Chinese use for making paper. Their paper is far better than ours, because the raw material is better; and a good deal was said about this thin, light Chinese paper, for if it is light and thin, the texture is close, there are no transparent spots in it. In Paris there are learned men among the printers' readers; Fourier and Pierre Leroux are Lachevardiere's readers at this moment; and the Comte de Saint-Simon, who happened to be correcting proofs for us, came in in the middle of the discussion. He told us at once that, according to Kempfer and du Halde, the _Broussonetia_ furnishes the substance of the Chinese paper; it is a vegetable substance (like linen or cotton for that matter). Another reader maintained that Chinese paper was principally made of an animal substance, to wit, the silk that is abundant there. They made a bet about it in my presence. The Messieurs Didot are printers to the Institute, so naturally they referred the question to that learned body. M. Marcel, who used to be superintendent of the Royal Printing Establishment, was umpire, and he sent the two readers to M. l'Abbe Grozier, Librarian at the Arsenal. By the Abbe's decision they both lost their wages. The paper was not made of silk nor yet from the _Broussonetia_; the pulp proved to be the triturated fibre of some kind of bamboo. The Abbe Grozier had a Chinese book, an iconographical and technological work, with a great many pictures in it, illustrating all the different processes of paper-making, and he showed us a picture of the workshop with the bamboo stalks lying in a heap in the corner; it was extremely well drawn. "Lucien told me that your father, with the intuition of a man of talent, had a glimmering of a notion of some way of replacing linen rags with an exceedingly common vegetable product, not previously manufactured, but taken direct from the soil, as the Chinese use vegetable fibre at first hand. I have classified the guesses made by those who came before me, and have begun to study the question. The bamboo is a kind of reed; naturally I began to think of the reeds that grow here in France.
