David demonstrates his invention to his father

David Séchard’s demonstration of his papermaking invention to his father turns a practical test into a reckoning over money, trust, and family obligation. In a makeshift workshop at Marsac, David produces thirty strong, fine sheets from plant stems, apparently proving the central promise of his discovery. Yet Père Séchard declines to finance him, seizing on an unfinished problem in the paper’s sizing. The invention passes its first visible test; the father-son appeal does not.

Background and Purpose

David arrives at Marsac with Kolb at about eight in the evening, while his father is finishing dinner and nearing his usual bedtime. David has been led to make one last attempt to move his father’s heart. He does not reveal the details of his secret at first. Instead, he offers to give his father an interest in the venture in exchange for the money he needs either to free himself from immediate pressure or to exploit the discovery.

The urgency is practical as well as personal. David is fleeing Victor-Ange-Herménégilde Doublon and has no paper or materials with him, only the clothes he is wearing. He asks his father for a securely closed room where no one can enter or watch him work. The request makes the demonstration itself the proposed proof: rather than asking his father to accept a claim on trust, David offers to produce the material in front of him, under controlled conditions.

The proposal also revives a long history of financial grievance. David had accepted the printing works at a price his father set himself, and he says he had even left his mother’s property to his father. He had borne the burdensome life created by that arrangement without complaint, hoping to make his own fortune without troubling his family. Now, exhausted by debts that are not his, he asks for help not only for himself but for his wife and young child. The invention is therefore presented as a possible business, but the request tests whether his father will recognize an obligation beyond the narrow terms of business.

The Overnight Demonstration

Père Séchard initially demands to know how David can make beautiful paper for nothing. David proposes to work in the cellar and asks for a cauldron and plant matter: artichoke stems, asparagus stems, stinging nettles, and reeds gathered along the small river. His father offers a conditional prospect of 25,000 francs, provided the investment can earn him the same amount every year. The sum gives the encounter a concrete commercial measure, but it is not a commitment: David must first demonstrate what the materials can produce.

Kolb rides to Mansle to obtain a large horsehair sieve from a cooper and glue from a grocer. Père Séchard supplies food and wine, then gathers the green plant material himself, joking in effect that the raw ingredients look too green. Around eleven, he shuts David and Kolb into a small tiled room adjoining the cellar. The room contains equipment used for distilling the wines of the Angoumois into Cognac brandy; for David, it offers the tubs, wood, and enclosed space needed for an improvised papermaking trial.

David and Kolb spend about two hours breaking and preparing the stems with two heavy beams while a fire burns and water boils. Their work takes place under the father’s watch, though not in the way David intended: Père Séchard has used the outer door to admit them, then peers through a small square opening above the inner door, concealed by empty casks. The makeshift laboratory thus becomes a scene of both experiment and suspicion. David has asked for privacy because he does not trust his father in business; his father, in turn, secretly observes the very test meant to persuade him.

At four the next morning, David emerges with about thirty sheets. Their fineness, whiteness, consistency, and strength are satisfactory, and the horsehair sieve has left watermark-like lines of varying strength. Père Séchard examines the samples as an experienced printer would: he tastes the paper, handles and crumples it, folds it, and tests its qualities. The material gives him little to criticize, but he postpones judgment until it has been tested on a printing press. Even the success of the immediate demonstration does not make him acknowledge defeat in the argument.

The Conditional Offer and Refusal

David himself identifies a remaining weakness. The paper still seems too expensive to make, and he wants to solve the problem of sizing in the vat. Although he can size it in the vat, the glue does not penetrate the pulp evenly, leaving the paper rough like a brush. This is a specific technical limit, not a failure to produce paper: the samples are strong and usable in appearance, but the process has not yet achieved the quality and economy David seeks.

Père Séchard turns that limitation into a condition. David must perfect the vat-sizing process before his father will provide the money. The offer shifts from the earlier prospect of 25,000 francs to an indefinite promise dependent on further work. David’s invention is neither dismissed as impossible nor funded on the strength of what he has shown. His father acknowledges only the next obstacle, allowing the demand for proof to recede whenever David meets it.

In private, David explains how he has understood their past dealings: he has seen a father in the man who sold him the printing works at his own valuation, and he has allowed an old man to enjoy the fruits of his labor. He says he had hoped to make a fortune without imposing on him. Now that he has found the secret while hungry, in debt, and under strain, he asks his father to consider the needs of a wife and a small child. David’s tears make plain how much this appeal costs him. Père Séchard reads them differently, treating his son’s distress as evidence of a failed scheme or an attempt to take advantage of him. He refuses to enter a business arrangement, insists that he is a vine-grower rather than a banker, and offers dinner instead of the assistance David requested.

Aftermath and Significance

David and Kolb leave Marsac around midnight and return to Angoulême on foot, taking precautions as if they were thieves. David is soon brought, without witnesses, to the refuge prepared by Basine Clerget, where his wife has arranged for him to hide. The failed appeal therefore has an immediate consequence: despite having demonstrated that he can make excellent sheets, David remains without his father’s backing and must continue to seek safety and support elsewhere. Kolb, Marion, and David’s mother have already contributed their savings, a contrast that sharpens the father’s refusal.

Père Séchard’s response is not simply a verdict on the paper. He has examined it closely enough to recognize its qualities, and his conditional promise shows that he sees a possible profit. Yet he interprets the family relationship through suspicion of exploitation, while David continues to approach him with patience and a willingness to excuse past injury. Their opposing readings of the same encounter—David’s tears as the disclosure of accumulated hardship, his father’s as proof of failure—make the estrangement more consequential than a failed business negotiation.

Two days later, Père Séchard comes to stay in one of the attic rooms he has reserved above his daughter-in-law’s apartment. The narration connects his visit to avarice: he wants to know whether the discovery offers a chance of fortune and to keep watch. He lives there while overlooking the household’s financial want. The demonstration thus ends with a bitter reversal. The father who refused to invest in David’s work moves closer to the household not to relieve its immediate hardship, but to monitor the potential value of the invention.
