"Talpidae!" cried Dr. Bird. "Carnes, they are a race of giant intellectual moles!"
Despite the fact that they had no visible eyes, the creatures were strongly affected by the light. They dropped on all fours and turned their backs to the scientist and the detective. Two of them scurried away down a long tunnel which opened from the room in which they stood. Dr. Bird turned his light up and swept the room. It was roughly circular, a hundred feet in diameter, with a roof ten feet high. Dozens of tunnels led off in every direction.
"Your light, Carnes, quick!" cried the doctor in a strained voice. Carnes reached toward the table for his light. Before he could reach it he was frozen into immobility. From the corner of his eye he could watch the doctor. Dr. Bird was struggling to bring the light back on the moles which stood before them. Great beads of sweat stood out on his forehead. Inch by inch he moved the light closer to his goal, but Carnes could see that his thumb was stealing up toward the switch button. His breath came in sobs. Suddenly the light went out.
For some time the two men sat motionless on the bench unable to speak or move. One of the moles stepped before them and gave a mental command. The two rose to their feet. For a mile or more they followed their guide, then, at a silent command, they turned to the right for a few steps and stopped. In another moment, the numbing influence had departed.
"Yes, right as can be. Doctor, what were those things? Where are we? What's it all about?"
"We'll find out in time, I guess," replied the doctor with a chuckle. "Carnes, isn't this the darnedest thing we've ever been through? Captured half a mile underground by a race of giant talpidae before whose mental orders we are as helpless as children. Did you understand any of their talk?"
"Well, mental conversation then. They made no sound."
"No. All I understood was the orders I obeyed."
"I got a great deal of it," the doctor said. "We are evidently in or near a sort of central community of these fellows. They spoke; thought is a better word; they thought of doing away with us but decided to wait until they consulted someone with more authority. You see, we are not airplane pilots. Captain Garland was taken at once to the place where they have other aviators imprisoned."
