It was precisely at this unpropitious moment that M. de Soissons proffered his demand, which was warmly seconded by Madame de Verneuil, who represented to the monarch the impossibility of his refusing a favour of this nature to a Prince of the Blood, when he had so frequently made concessions of the same nature to individuals of inferior rank; and the certainty that, were his request negatived, M. de Soissons would not fail to feel himself at once injured and aggrieved. Still, mindful of the promise which had been extorted from him by Sully, the King hesitated; but upon being more urgently pressed by the favourite, he at length demanded what would be the probable yearly produce of the tax, when he was assured by the Count that it could not exceed ten thousand crowns; upon which Henry, who was anxious not to irritate him by a refusal where the favour solicited was so comparatively insignificant, at once signified his compliance; and as the subject had been cleverly mooted by the two interested parties at Fontainebleau, while the minister of finance was absent in the capital, Madame de Verneuil, by dint of importunity, succeeded in inducing the monarch to sign an order for the immediate imposition of the duty in favour of M. de Soissons; but before he was prevailed upon to do this, he declared to the Prince that he should withdraw his consent to the arrangement, if it were proved that the produce of the tax exceeded the yearly sum of fifty thousand francs, or that it pressed too heavily upon the people and the commercial interests of the kingdom. This reservation was by no means palatable to M. de Soissons, who had, when questioned as to the amount likely to be derived from the transaction, answered rather from impulse than calculation; but as the said reservation was merely verbal, while the edict authorizing the levy of the impost was tangible and valid, the Prince, after warmly expressing his acknowledgments to the monarch, carried off the document without one misgiving of success. Henry, however, when he began to reflect upon the nature of the concession which he had been prevailed upon to make, could not suppress a suspicion that it was more important than it had at first appeared; and, conscious that he had falsified his promise to the minister, he resolved to ascertain the extent of his imprudence. He accordingly, the same evening, despatched a letter to Sully, in which, without divulging what had taken place, he directed him to ascertain the probable proceeds of such a tax, and the effect which it was likely to produce upon those on whom it would be levied.
