"I'm glad to meet you, Major," said Carnes. "The resemblance is positively uncanny. But for your hands, I would have trouble telling you two apart." * * * * * The Major glanced down at his stubby fingers. "It is unfortunate but it can't be helped," he said. "Dr. Bird, this is Corporal Askins of my command. He is not as good a second to Mr. Carnes as I am to you but you said it was less important." "The likeness is plenty good enough," replied the Doctor. "He will probably not be subjected to as close a scrutiny as you will. Did you have any trouble in getting here unobserved?" "None at all, Doctor. Lieutenant Maynard found a good landing field within a half mile of here, as you said he would, and he has his Douglass camouflaged and is standing by. When do you expect trouble?" "I have no idea. It may come to-night or it may come later. Personally I hope that it comes later so that we can get in a few days of fishing before anything happens." "What do you expect to happen, Doctor?" demanded Carnes. "Every time I have asked you anything you told me to wait until we were in the Maine woods and we are there now. I read up everything that I could find on amnesia victims during the past three months but it didn't throw much light on the matter to me." "How many cases did you find, Carnes?" "Sixteen. There may have been lots more but I couldn't find any others in the _Post_ records. Of course, unless the victim were a local man, or of some prominence, it wouldn't appear." "You got most of them at that. Did any points of similarity strike you as you read them?" "None except that all were prominent men and all of them mental workers of high caliber. That didn't appear peculiar because it is the man of high mentality who is most apt to crack." "Undoubtedly. There were some points of similarity which you missed. Where did the attacks take place?" "Why, one was at--Thunder, Doctor! I did miss something. Every case, as nearly as I can recall, happened at some summer camp or other resort where they were on vacation." "Correct. One other point. At what time of day did they occur?" "In the morning, as well as I can remember. That point didn't register." "They were all discovered in the morning, Carnes, which means that the actual loss of memory occurred during the night. Further, every case has happened within a circle with a diameter of three hundred miles. We are near the northern edge of that circle." * * * * * Carnes checked up on his memory rapidly. "You're right, Doctor," he cried. "Do you think--?" "Once in a while," replied Dr. Bird dryly, "I think enough to know the futility of guesses hazarded without complete data. We are now located within the limits of the amnesia belt and we are here to find out what did happen, if anything, and not to make wild guesses about it. You have the tent set up for us, Major?"
