He pointed out that the vehicle was practically unpursuable; that in its earlier appearances, it had apparently vanished from all roads even before a telephone message could be sent ahead. Active and numerous police agents had been spread throughout the country, but no one of them had encountered the delinquent. He did not move continuously from place to place, even at his amazing speed, but seemed to appear only for a moment and then to vanish into thin air. True, he had at length remained visible along the entire route from Prairie-du-Chien to Milwaukee, and he had covered in less than an hour and a half this track of two hundred miles. But since then, there had been no news whatever of the machine. Arrived at the end of the route, driven onward by its own impetus, unable to stop, had it indeed been engulfed within the waters of Lake Michigan? Must we conclude that the machine and its driver had both perished, that there was no longer any danger to be feared from either? The great majority of the public refused to accept this conclusion. They fully expected the machine to reappear. Mr. Ward frankly admitted that the whole matter seemed to him most extraordinary; and I shared his view. Assuredly if this infernal chauffeur did not return, his apparition would have to be placed among those superhuman mysteries which it is not given to man to understand. We had fully discussed this affair, the chief and I; and I thought that our interview was at an end, when, after pacing the room for a few moments, he said abruptly, “Yes, what happened there at Milwaukee was very strange. But here is something no less so!” With this he handed me a report which he had received from Boston, on a subject of which the evening papers had just begun to apprise their readers. While I read it, Mr. Ward was summoned from the room. I seated myself by the window and studied with extreme attention the matter of the report. For some days the waters along the coast of Maine, Connecticut, and Massachusetts had been the scene of an appearance which no one could exactly describe. A moving body would appear amid the waters, some two or three miles off shore, and go through rapid evolutions. It would flash for a while back and forth among the waves and then dart out of sight. The body moved with such lightning speed that the best telescopes could hardly follow it. Its length did not seem to exceed thirty feet. Its cigar-shaped form and greenish color, made it difficult to distinguish against the background of the ocean. It had been most frequently observed along the coast between Cape Cod and Nova Scotia. From Providence, from Boston, from Portsmouth, and from Portland motor boats and steam launches had repeatedly attempted to approach this moving body and even to give it chase. They could not get anywhere near it. Pursuit seemed useless. It darted like an arrow beyond the range of view.
