Decidedly, thought I, the devil has many uses; and if he did not exist we would have to invent him, to give people some way of explaining the inexplicable. It was he who lit the flames of the Great Eyrie. It was he who smashed the record in the Wisconsin race. It is he who is scurrying along the shores of Connecticut and Massachusetts. But putting to one side this evil spirit who is so necessary, for the convenience of the ignorant, there was no doubt that we were facing a most bewildering problem. Had both of these machines disappeared forever? They had passed like a meteor, like a star shooting through space; and in a hundred years the adventure would become a legend, much to the taste of the gossips of the next century. For several days the newspapers of America and even those of Europe continued to discuss these events. Editorials crowded upon editorials. Rumors were added to rumors. Story tellers of every kind crowded to the front. The public of two continents was interested. In some parts of Europe there was even jealousy that America should have been chosen as the field of such an experience. If these marvelous inventors were American, then their country, their army and navy, would have a great advantage over others. The United States might acquire an incontestable superiority. Under the date of the tenth of June, a New York paper published a carefully studied article on this phase of the subject. Comparing the speed of the swiftest known vessels with the smallest minimum of speed which could possibly be assigned to the new boat, the article demonstrated that if the United States secured this secret, Europe would be but three days away from her, while she would still be five days from Europe. If our own police had searched diligently to discover the mystery of the Great Eyrie, the secret service of every country in the world was now interested in these new problems. Mr. Ward referred to the matter each time I saw him. Our chat would begin by his rallying me about my ill-success in Carolina, and I would respond by reminding him that success there was only a question of expense. “Never mind, my good Strock,” said he, “there will come a chance for our clever inspector to regain his laurels. Take now this affair of the automobile and the boat. If you could clear that up in advance of all the detectives of the world, what an honor it would be to our department! What glory for you!” “It certainly would, Mr. Ward. And if you put the matter in my charge—” “Who knows, Strock? Let us wait a while! Let us wait!” Matters stood thus when, on the morning of June fifteenth, my old servant brought me a letter from the letter-carrier, a registered letter for which I had to sign. I looked at the address. I did not know the handwriting. The postmark, dating from two days before, was stamped at the post office of Morganton. Morganton! Here at last was, no doubt, news from Mr. Elias Smith.
