My choice of the two men to accompany me was easily made. They both belonged to my own department, and had many times under my direct command given proofs of their vigor, courage and intelligence. One, John Hart, of Illinois, was a man of thirty years; the other, aged thirty-two, was Nab Walker, of Massachusetts. I could not have had better assistants. Several days passed, without news, either of the automobile, the boat, or the submarine. There were rumors in plenty; but the police knew them to be false. As to the reckless stories that appeared in the newspapers, they had most of them, no foundation whatever. Even the best journals cannot be trusted to refuse an exciting bit of news on the mere ground of its unreliability. Then, twice in quick succession, there came what seemed trustworthy reports of the “man of the hour.” The first asserted that he had been seen on the roads of Arkansas, near Little Rock. The second, that he was in the very middle of Lake Superior. Unfortunately, these two notices were absolutely unreconcilable; for while the first gave the afternoon of June twenty-sixth, as the time of appearance, the second set it for the evening of the same day. Now, these two points of the United States territory are not less than eight hundred miles apart. Even granting the automobile this unthinkable speed, greater than any it had yet shown, how could it have crossed all the intervening country unseen? How could it traverse the States of Arkansas, Missouri, Iowa and Wisconsin, from end to end without any one of our agents giving us warning, without any interested person rushing to a telephone? After these two momentary appearances, if appearances they were, the machine again dropped out of knowledge. Mr. Ward did not think it worth while to dispatch me and my men to either point whence it had been reported. Yet since this marvelous machine seemed still in existence, something must be done. The following official notice was published in every newspaper of the United States under July 3d. It was couched in the most formal terms. “During the month of April, of the present year, an automobile traversed the roads of Pennsylvania, of Kentucky, of Ohio, of Tennessee, of Missouri, of Illinois; and on the twenty-seventh of May, during the race held by the American Automobile Club, it covered the course in Wisconsin. Then it disappeared. “During the first week of June, a boat maneuvering at great speed appeared off the coast of New England between Cape Cod and Cape Sable, and more particularly around Boston. Then it disappeared. “In the second fortnight of the same month, a submarine boat was run beneath the waters of Lake Kirdall, in Kansas. Then it disappeared. “Everything points to the belief that the same inventor must have built these three machines, or perhaps that they are the same machine, constructed so as to travel both on land and water.
