"At nine, then," she said. "No. 8 Rue d'Alouette." I bowed, took my hat, gloves, and stick, and attended her to her carriage below. Long after the blue-and-black victoria had whirled away down the crowded quay I stood looking after it, mazed in the web of that ancient enchantment whose spell fell over the first man in Eden, and whose sorcery shall not fail till the last man returns his soul. X I lunched at my lodgings on the Quai Malthus, and I had but little appetite, having fed upon such an unexpected variety of emotions during the morning. Now, although I was already heels over head in love, I do not believe that loss of appetite was the result of that alone. I was slowly beginning to realize what my recent attitude might cost me, not only in an utter collapse of my scientific career, and the consequent material ruin which was likely to follow, but in the loss of all my friends at home. The Zoological Society of Bronx Park and the Smithsonian Institution of Washington had sent me as their trusted delegate, leaving it entirely to me to choose the subject on which I was to speak before the International Congress. What, then, would be their attitude when they learned that I had chosen to uphold the dangerous theory of the existence of the ux. Would they repudiate me and send another delegate to replace me? Would they merely wash their hands of me and let me go to my own destruction? "I will know soon enough," thought I, "for this morning's proceedings will have been cabled to New York ere now, and read at the breakfast-tables of every old, moss-grown naturalist in America before I see the Countess d'Alzette this evening." And I drew from my pocket the roll of paper which she had given me, and, lighting a cigar, lay back in my chair to read it. The manuscript had been beautifully type-written, and I had no trouble in following her brief, clear account of the circumstances under which the notorious ux-skin had been obtained. As for the story itself, it was somewhat fishy, but I manfully swallowed my growing nervousness and comforted myself with the belief of Darwin in the existence of the ux, and the subsequent testimony of Wallace, who simply stated what he had seen through his telescope, and then left it to others to identify the enormous birds he described as he had observed them stalking about on the snowy peaks of the Tasmanian Alps. My own knowledge of the ux was confined to a single circumstance. When, in 1897, I had gone to Tasmania with Professor Farrago, to make a report on the availability of the so-called "Tasmanian devil," as a substitute for the mongoose in the West Indies, I of course heard a great deal of talk among the natives concerning the birds which they affirmed haunted the summits of the mountains.
