"We're cornered all right," he said. "If we did elude the men in that truck, we would have a plane after us in no time. You might as well turn back, McCready, and land fairly near the building. We are sure to be captured and our best chance is to have the plane near us. They'll probably patch it up and if we get a chance to escape later, it may be a lifesaver. At any rate, we've lost for the present." * * * * * McCready turned the plane again to the west. The truck halted at their new maneuver. As the plane passed over, it turned and again followed them. The ground was approaching rapidly. With a final dip, McCready leveled off and made a landing. The machine rolled to a stop about a mile from the building. The truck was less than three hundred yards away. It came up rapidly and disgorged a dozen men armed with rifles who hurried forward. In the lead was a tall, slight figure who carried no gun. Dr. Bird stepped forward to meet them. "Do you understand English?" he asked. An incomprehensible jargon of Russian answered him. The men raised their rifles threateningly. Dr. Bird turned back to his companions. "Resistance is hopeless," he said. "Surrender gracefully and we'll see what comes of it." He faced the Russians and held one hand high above his head. The Russian leader stepped forward and confiscated the doctor's pistol. He repeated the process with Carnes and McCready, frisking them thoroughly for concealed weapons. At his command, six of the Russians stepped forward. The Americans took their place in the midst of the guard and were marched to the truck. The balance of the Russians moved over to the American's plane. The truck rolled forward and approached the low building. The projection which Dr. Bird had noticed from the air proved to be a metal tube projection from the roof, fully twenty feet in diameter and fifty feet long. "A projection tube of some sort," said the doctor, pointing. An excited command came from the Russian in command. A rifle was leveled threateningly at the doctor. He took the hint and maintained silence while they climbed down from the truck and approached the door of the building. It swung open as they approached. As they entered a strong garlic-like smell was evident. The hum of heavy machinery smote their ears. * * * * * They were led down a corridor to a flight of steps. On the floor below they went along another corridor to a heavy iron-studded door. The guide unlocked it with a huge key and swung it open. With a shrug of his shoulders, Dr. Bird led the way into the cell. The door closed behind them and they were left alone. Dr. Bird turned to his companions. "Be careful what you say," he whispered. "I am not at all convinced that there is no one here who knows English and we are probably spied upon. There is almost sure to be a dictaphone somewhere in this room. We don't want to give them any more information than we have to."
