 Now, here's the way I'm rigging it up, Mr. Hafner. Whatever it is, it spotted the photoelectric cell rig. So I've worked up an alarm that reacts to body radiation. You're sure the animal won't spot that? Well, I'm burying it in the field. Then we'll move the visible alarms to another field. All right, Kelly. As soon as the alarm goes off, notify Mr. Marin and me. Do you understand? Yes, sir. Just as soon as the alarm goes off.
