Cardon the banker； owner of the pulping troughs of Bruges and Langlee （where Leorier de l'Isle endeavored in 1776 to solve the very problem that occupied your father）； Cardon brought an action against one Proust for an error in weights of two millions in a total of ten million pounds' weight of rags； worth about four million francs！ The manufacturer washes the rags and reduces them to a thin pulp； which is strained； exactly as a cook strains sauce through a tamis； through an iron frame with a fine wire bottom where the mark which give its name to the size of the paper is woven。 The size of this mould； as it is called； regulates the size of the sheet。
〃When I was with the Messieurs Didot；〃 David continued； 〃they were very much interested in this question； and they are still interested； for the improvement which your father endeavored to make is a great commercial requirement； and one of the crying needs of the time。 And for this reason： although linen lasts so much longer than cotton； that it is in reality cheaper in the end； the poor would rather make the smaller outlay in the first instance； and； by virtue of the law of Vae victis！ pay enormously more before they have done。 The middle classes do the same。 So there is a scarcity of linen。 In England； where four… fifths of the population use cotton to the exclusion of linen； they make nothing but cotton paper。 The cotton paper is very soft and easily creased to begin with； and it has a further defect： it is so soluble that if you seep a book made of cotton paper in water for fifteen minutes； it turns to a pulp； while an old book left in water for a couple of hours is not spoilt。 You could dry the old book； and the pages； though yellow and faded； would still be legible； the work would not be destroyed。
〃There is a time coming when legislation will equalize our fortunes； and we shall all be poor together； we shall want our linen and our books to be cheap； just as people are beginning to prefer small pictures because they have not wall space enough for large ones。 Well； the shirts and the books will not last； that is all； it is the same on all sides； solidity is drying out。 So this problem is one of the first importance for literature； science； and politics。
〃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。
〃Labor is very cheap in China； where a workman earns three halfpence a day； and this cheapness of labor enables the Chinese to manipulate each sheet of paper separately。 They take it out of the mould； and press it between heated tablets of white porcelain； that is the secret of the surface and consistence； the lightness and satin smoothness of the best paper in the world。 Well； here in Europe the work must be done by machinery； machinery must take the place of cheap Chinese labor。 If we could but succeed in making a cheap paper of as good a quality； the weight and thickness of printed books would be reduced by more than one…half。 A set of Voltaire； printed on our woven paper and bound； weighs about two hundred and fifty pounds； it would only weigh fifty if we used Chinese paper。 That surely would be a triumph； for the housing of many books has come to be a difficulty； everything has grown smaller of late； this is not an age of giants； men have shrunk； everything about them shrinks； and house…room into the bargain。 Great mansions and great suites of rooms will be abolished sooner or later in Paris； for no one will afford to live in the great houses built by our forefathers。 What a disgrace for our age if none of its books should last！ Dutch paperthat is； paper made from flaxwill be quite unobtainable in ten years' time。 Well； your brother told me of this idea of your father's； this plan for using vegetable fibre in paper… making； so you see that if I succeed； you have a right to〃
Lucien came up at that moment and interrupted David's generous assertion。
〃I do not know whether you have found the evening pleasant；〃 said he； 〃it has been a cruel time for me。〃
〃Poor Lucien！ what can have happened？〃 cried Eve； as she saw her brother's excited face。
The poet told the history of his agony； pouring out a flood of clamorous thoughts into those friendly hearts； Eve and David listening in pained silence to a torrent of woes that exhibited such greatness and such pettiness。
〃M。 de Bargeton is an old dotard。 The indigestion will carry him off before long； no doubt；〃 Lucien said； as he made an end； 〃and then I will look down on these proud people； I will marry Mme。 de Bargeton。 I read to…night in her eyes a love as great as mine for her。 Yes； she felt all that I felt； she comforted me； she is as great and noble as she is gracious and beautiful。 She will never give me up。〃
〃It is time that life was made smooth for him； is it not？〃 murmured David； and for answer Eve pressed his arm without speaking。 David guessed her thoughts； and began at once to tell Lucien about his own plans。
If Lucien was full of his troubles； the lovers were quite as full of themselves。 So absorbed were they； so eager that Lucien should approve their happiness； that neither Eve nor David so much as noticed his start of surprise at the news。 Mme。 de Bargeton's lover had been dreaming of a great match for his sister； he would reach a high position first； and then secure himself by an alliance with some family of influence； and here was one more obstacle in his way to success！ His hopes were dashed to the ground。 〃If Mme。 de Bargeton consents to be Mme。 de Rubempre； she would never care to have David Sechard for a brother…in…law！〃
This stated clearly and precisely was the thought that tortured Lucien's inmost mind。 〃Louise is right！〃 he thought bitterly。 〃A man with a career before him is never understood by his family。〃
If the marriage had not been announced immediately after Lucien's fancy had put M。 de Bargeton to death； he would have been radiant with heartfelt delight at the news。 If he had thought soberly over the probable future of a beautiful and penniless girl like Eve Chardon； he would have seen that this marriage was a piece of unhoped…for good fortune。 But he was living just now in a golden dream； he had soared above all barriers on the wigs of an IF； he had seen a vision of himself； rising above society； and it was painful to drop so suddenly down to hard fact。
Eve and David both thought that their brother was overcome with the sense of such generosity； to them； with their noble natures； the silent consent was a sign of true friendship。 David began to describe with kindly and cordial eloquence the happy fortunes in store for them all。 Unchecked by protests put in by Eve； he furnished his first floor with a lover's lavishness； built a second floor with boyish good faith for Lucien； and rooms above the shed for Mme。 Chardonhe meant to be a son to her。 In short； he made the whole family so happy and his brother…in…law so independent； that Lucien fell under the spell of David's voice and Eve's caresses； and as they went through the shadows beside the still Charente； a gleam in the warm； star…lit night； he forgot the sharp crown of thorns that had been pressed upon his head。
