Here the conversation was interrupted by the arrival of a person who was brought to the door in a chair, and conducted into another apartment, from which a message was brought to the Count, importing, that the stranger desired to speak with him upon business of the last importance. Fathom having chid the servant for admitting people without his order, desired the Swiss to excuse him for a minute longer, and went in to the next room, from whence the following dialogue was overheard by this challenger:--"Count," said the stranger, "you are not ignorant of my pretensions to the heart of that young lady, at whose house I met you yesterday; therefore you cannot be surprised when I declare myself displeased with your visits and behaviour to my mistress, and demand that you will instantly promise to drop the correspondence." "Else what follows?" answered Ferdinand, with a cool and temperate voice. "My resentment and immediate defiance," replied the other; "for the only alternative I propose is, to forego your design upon that lady, or to decide our pretension by the sword." Our hero, having expressed a regard for this visitant as the son of a gentleman whom he honoured, was at the pains to represent the unreasonableness of his demand, and the folly of his presumption; and earnestly exhorted him to put the issue of his cause upon a more safe and equitable footing. But this admonition, instead of appeasing the wrath, seemed to inflame the resentment of the opponent, who swore he would not leave him until he should have accomplished the purport of his errand. In vain our adventurer requested half an hour for the despatch of some urgent business, in which he was engaged with a gentleman in the other parlour. This impetuous rival rejected all the terms he could propose, and even challenged him to decide the controversy upon the spot; an expedient to which the other having assented with reluctance, the door was secured, the swords unsheathed, and a hot engagement ensued, to the inexpressible pleasure of the Swiss, who did not doubt that he himself would be screened from all danger by the event of this rencontre. Nevertheless, his hope was disappointed in the defeat of the stranger, who was quickly disarmed, in consequence of a wound through the sword-arm; upon which occasion Fathom was heard to say, that, in consideration of his youth and family, he had spared his life; but he would not act with the same tenderness towards any other antagonist. He then bound up the limb he had disabled, conducted the vanquished party to his chair, rejoined the chevalier with a serene countenance, and, asking pardon for having detained him so long, proposed they should instantly set out in a hackney-coach for the place of appointment.
