But the Chicago _Herald_ had been working thoroughly and saying little until its issue of June 16th, when it claimed the credit of solving the whole mystery. Its long article lies before me as I write: There had been no suicide; there had been no murder; there had been no infernal machine. Doctor Anderwelt was a learned man, and the warm personal friend of Isidor Werner. Both men had shared the same fate; they might yet be alive, but they were certainly _at the bottom of Lake Michigan together_! They were imprisoned there in a sunken submarine boat, which was the invention of Doctor Anderwelt, and was built with funds furnished by the young broker. The foundryman who had constructed the big torpedo-shaped contrivance had been interviewed. He knew both men, and they were on the most friendly terms. In a moment of confidence Doctor Anderwelt had told him the machine was for submarine exploration; had explained the four-winged rudder, which would make it dive into the water, rise to the surface, or direct it to right or to left. Moreover, there were closed living compartments, around which were chambers containing a supply of air. He himself had pumped them full of compressed air, and it was so arranged that foul air could be let out when used and new air admitted. When all had been finished the foundryman had shipped the new invention, _via_ the Michigan Southern Railway, to the shore of the Lake near Whiting, Indiana. Next the _Herald_ had sought and found the conductor whose train had hauled it to Whiting. He remembered switching off the flat-car there, and he was surprised on his return trip next morning to see the heavy thing already unloaded and gone. Undoubtedly, the two men had made an experiment with the diving boat under the surface of the water; and its failure to operate as hoped had resulted in its sinking to the bottom, with the two men imprisoned in it. On no other hypothesis could its disappearance, and that of the two men, be so plausibly accounted for. But as they had stores of air, and probably of food, there was a possibility that they were still alive inside the thing in the bottom of the Lake! Only three days had elapsed since it had been launched, and the _Herald_ was willing to head a subscription to drag the Lake and send divers to search for and rescue the two unfortunate men! All this serves to illustrate the untiring energy of newspaper investigation, as well as the remarkable fertility of journalistic imagination; for none of these clever theories hit at the real truth, or explained the correct bearing of the astonishing facts which the newspapers had so industriously unearthed.
