"Yes," he replied. "It was at Hoboken. De Aëry and myself spent years in the construction of that machine, and a large amount of money. On the day when the trial of its powers was to have taken place, the weather proved unfavorable, and we met with unexpected delays. The spectators, who had congregated by thousands, became impatient; and the mob, breaking in upon us, destroyed in an hour property which had cost us five thousand dollars and the labor of years."
I felt obliged to sympathize with Mr. Bonflon. He had met with the usual fortune of public benefactors, and particularly of inventors. His success, however, should it prove real, in the unexampled brilliancy of its results, would more than compensate him for all his disappointments and losses. He would rank as the greatest of discoverers,—as the master mind of this master century.
Leading him off from this one topic into general conversation, I held him thus engaged for an hour. I was charmed with his comprehensive intelligence, and with the scope and liberality of his views. In everything relating to mechanics, his opinions were marked with originality. This had evidently been his favorite field, where his quick perceptions and powers of concentration and analysis had elevated him to an eminence where he stood almost alone. I had never met his equal. In plausible suggestions relative to the possibilities of the future, he took me quite above my level, and left me floating in a maze of glittering bewilderment. But I could discover no breaks, no confusion in his mind, on the themes he presented. His premises were apparently well considered, and his conclusions the fair and natural sequences flowing from them.
On the following day, Mr. Bonflon called on me again. In the interval, my friend and myself had held extended consultations. My friend, while externally calm as the surface of a summer sea, as was his wont, it was plain for me to see, was internally deeply stirred and excited by the extraordinary nature of Mr. Bonflon's revelations. Acknowledging a mutual and increasing interest in the intelligent inventor, we nevertheless parted in a wilderness of doubt. There was a mystery in the matter,—a surprise for the world or a surprise for ourselves,—which time, it would seem, with its busy thumb and finger, must be left to unravel at its leisure.
Mr. Bonflon had not brought the California paper with him. The two or three copies only which had come into his possession had been handed around among his confidential friends, and he had not been able to lay his hand on one. He informed me that the "Flying Cloud" was expected to return in three days, and, after remaining two days on the Atlantic side of the continent, would then start on her third experimental trip to the Pacific. At that time he expected to make one of the party himself, and he invited me to accompany him.
I accepted the invitation, and received from him particular instructions as to the nature of my outfit. It was in the midst of the heats of summer. He advised, however, a full supply of thick clothing, on account of the increased chill and coldness of the atmosphere at high altitudes; and, indeed, recommended a mail of flannel next the skin. Everything else—the supply of the larder, with an excellent cook, beds, and so forth—would be found amply provided by De Aëry and himself for the comfort and accommodation of their guests. The station, or point of departure, Mr. Bonflon informed me, was a retired spot but a few miles out of the city of Baltimore; and he promised to be at hand at the proper time to accompany me in person, and see me safely on board the "Flying Cloud."
I saw nothing more of Mr. Bonflon for several days. Meanwhile I arranged my affairs for a brief absence, and, as my family were all off in the country, prepared a special letter for use, if needed, to be dated and mailed at the last moment, notifying them of a probable gap in my correspondence, on account of some pressing business which would take me out of the city for a few days and keep me constantly employed.
In three or four days I received a note from Mr. Bonflon, advising me to hold myself in readiness; and at the proper time, he presented himself before me. But he came to apologize. The "Flying Cloud" had returned. The second trip had been as successfully and safely performed as the first. Nothing had occurred to mar the pleasure of the voyage; but, unfortunately, before coming on to New York, De Aëry had filled out the complement of guests for the third grand expedition. Even he (Mr. Bonflon) should remain behind; but he should see that seats were reserved for us both, without fail, for the next succeeding trip. Mr. Bonflon took his leave; and I found myself more deeply involved in doubt and perplexity than ever. I could hardly say that I was disappointed, or that I was not. I had thrown myself on a wave, with no look-out or means of judging where I was to be cast, and had formed no opinions. As yet, everything looked fair with Mr. Bonflon. His face was as honest as the morning sun, and it was next to impossible to doubt him. He might be the prey of some strange phantasm, some monomania; but the evidences did not show it. The account he had given of himself was manly and coherent; his claims as a discoverer had been modestly presented, and were not wholly unsupported by circumstances, or unreasonable in themselves. Indeed, they must be regarded as coming within the range of probabilities fully as much as, to human seeming, had once the established, but ceaseless, wonders of steam locomotion and electric telegraphing.
Singularly enough,—and it illustrates the constantly shifting scenes in the kaleidoscope of life,—within an hour, Mr. Bonflon returned with a new message, and with the programme of the "Flying Cloud" changed, if not reversed. He had seen De Aëry again. One or two of the expected passengers had telegraphed that untoward circumstances would compel them to remain behind, and there would be room for us. But no time was to be lost; the air-steamer would weigh anchor before daylight of the following morning, and we must start for Baltimore by the next train. De Aëry and several others were already flying over the rail on their way to Philadelphia.
I did not allow myself to hesitate. With an unusual degree of excitement, made up of the mingled emotions of wonder, doubt, and, I frankly confess, apprehension, I dated and superscribed the letter to my absent family; and, taking my carpet-bag in my hand, packed to plethora several days before in readiness for the occasion, set out on the strange and questionable adventure.
