When he got back to his room, the radio was urging everybody to go to sleep and rest. There were guards detailed for necessary night work, and there was no danger. Freshness and strength would be needed tomorrow. But John was too excited following his strenuous day, and knew that sleep would be impossible. He kept on listening to the news from the radio, which was trying to solve the mystery of these Roman hordes. "Who are they?" the announcer asked rhetorically. "Where are they from? What do they want?" His questions were asked but not answered. He reported that during the afternoon the entire world had been searched by cable and radio, and nowhere was there any trace of the departure of such vast numbers of men. Italy and Russia were especially suspected; but it was out of the question that such hundreds of thousands could have been transported without leaving some evidence. How had they reached the middle of the North American continent? No railroad knew anything about them; there had been no unusual number of airships observed in any direction. One was tempted to think that they came out of the ground. Someone proposed the idea, based on the popularity of Einstein's recent conceptions, that these men had somehow crossed the time dimension from Julius Caesar's time; a fold in the continuum might readily bring the period of the Roman Senate in contact with the period of radio and automobiles. A few minutes later the announcer stated that he had received a dozen contemptuous and scornful messages about the idea from scientists and historians. If these troops had come from Caesar's time, their sudden disappearance would certainly have caused enough sensation to be recorded; and no such record existed. If they came from such a period, they must have disappeared from the sight of the people who lived then; otherwise one must assume that they went on existing in their own time as well as the present day. The idea was rent to bits. The announcer went on with rhetorical questions: How many more men were there? What would happen tomorrow? At least there were comforting reports that in the morning the sky would be crowded with planes bearing tons of high-explosive bombs. It could not last long. Suddenly John slapped his thigh. He went to the telephone and called up the aviation lieutenant. "Hello!" he said. "Did I get you out of bed? Well, it looks as though neither one of us is so bright about war." "Now what?" the lieutenant asked. "Those last two kegs of dynamite that you dropped on Caesar's army--" "Yes?" the lieutenant asked. "They ought to have been dumped on the buildings on the Indian Reservation, what?" A faint oath came over the phone. "Say, Hastings, I feel like resigning my commission and getting a job selling bananas. But, what do you say to correcting the oversight? At once?" "I'm there. But wait. I'm getting positively brilliant tonight. Why not get the Latin prof to go with us and see what we can find out?"
