“ HARVEY WINSTON, paying teller of the First National Bank of Chicago, stripped the band from a bundle of twenty dollar bills, counted out seventeen of them and added them to the pile on the counter before him.
"Twelve hundred and thirty-one tens," he read from the payroll change slip before him. The paymaster of the Cramer Packing Company nodded an assent and Winston turned to the stacked bills in his rear currency rack. He picked up a handful of bundles and turned back to the grill. His gaze swept the counter where, a moment before, he had stacked the twenties, and his jaw dropped. ”

“ My advice to you would be to keep out the patrolmen who are demanding admittance and get in touch with the chief of police. I would ask that his best detective together with an expert finger-print photographer be sent here before anyone else is mitted. If the patrolmen are allowed to wipe their hands over Mr. Winston's counter they may destroy valuable evidence."
"You are right, Mr. Carnes," exclaimed the cashier. "Mr. Jervis, will you tell the police that there is no violence threatening and ask them to wait for a few minutes? I'll telephone the chief of police at once." ”

“ The more I have thought about it, the more inclined I am to believe that Sturtevant is right and that it is an inside job. It seems to me impossible that a man could have entered in broad daylight and lifted that money in front of three men and within sight of a hundred more without some one getting a glimpse of him. He must have taken the money out in a grip or a sack or something like that, yet the bank record shows that no one but Trier entered with a grip and no one left with a package for ten minutes before Trier entered. ”

“ Trier?" he demanded, sharply.
"Of course not," replied the paymaster. "Winston's grill was closed. It still is. Granted that I might have reached the twenties he had piled up, how could I have gone through a grill and taken the rest of the missing money without his seeing me? The money disappeared almost instantly. It was there a moment before, for I noticed when Winston took the twenties from his rack that it was full."
"But someone must have taken it," said the bewildered cashier. "Money doesn't walk off of its own accord or vanish into thin air—"
A bell interrupted his speech. ”

“ It all depends on the light. The best flash-light powder gives a flash about one ten-thousandth of a second in duration, but that is by no means the speed limit of the film. The only trouble is enough light and sufficient shutter speed. Pictures have been taken by means of spark photography with an exposure of less than one three-millionth of a second. The whole secret of this machine lies in the shutter. This big disc with the slots in the edge is set up before the lens and run at such a speed that half a million slots per second pass before the lens. ”

“ The thief wore gloves."
"How in thunder do you know that?" demanded Carnes.
"It's merely common sense. A man who can do what he did had at least some rudiments of intelligence, and even the feeblest-minded crooks know enough to wear gloves nowadays."
Carnes stepped a little closer to the doctor.
"Another reason why I didn't want patrolmen tramping around," he said in an undertone, "is this. If Winston gave the alarm quickly enough, the thief is probably still in the building."
"He's a good many miles away by now," replied Dr. Bird with a shrug of his shoulders. ”

“ Ladd. An old track man like me can't let such an opportunity pass."
"I don't know what this is all about, Doctor," replied Carnes, "but I know you well enough to obey orders and to keep my mouth shut until it is my turn to speak."
Few men could resist Dr. Bird when he set out to make a favorable impression, and even a world's champion is apt to be flattered by the attention of one of the greatest scientists of his day, especially when that scientist has made an enviable reputation as an athlete in his college days and can talk the jargon of the champion's particular sport. ”

“ Bird as he followed Carnes out. "When you get through playing with your prisoners and start to look for the thief, here is a tip. Look for a left-handed man who has a thorough knowledge of chemistry and especially toxicology."
"It's easy enough to see that he was left-handed if he pulled that money out through the grill from the positions occupied by Trier and his guard, but what the dickens led you to suspect that he is a chemist and a toxicologist?" asked Carnes as he and the doctor left the bank. ”

“ The camera is equipped with a special lens ground out of rock crystal. This lens lets in ultra-violet light which the ordinary lens shuts out, and X-ray film is especially sensitive to ultra-violet light. In order to be sure that we get enough illumination, I will set up these two ultra-violet floodlights to illumine the cage. The teller will have to wear glasses to protect his eyes and he'll get well sunburned, but something has to be sacrificed to science, as Dr. Bird is always telling me. ”

“ We were in the bank, engaged on a counterfeiting case, when the robbery took place. We have had a good deal of experience along these lines and we are merely anxious to aid you."
Sturtevant examined Carnes' credentials carefully and returned them.
"This is a Chicago robbery," he said, "and we have had a little experience in robberies and in apprehending robbers ourselves. I think that we can get along without your help."
"You have had more experience with robberies that with apprehending robbers if the papers tell the truth," said Dr. Bird with a chuckle. ”

“ The film, which is sixteen millimeter X-ray film, travels behind the lens at a speed of nearly five miles per second. It has to be gradually worked up to this speed, and after the whole thing is set up, it takes it nearly four hours to get to full speed."
"At that speed, it must take a million miles of film before you get up steam."
"It would, if the film were being exposed. There is only about a hundred yards of film all told, which will run over these huge drums in an endless belt. There is a regular camera shutter working on an electric principle which remains closed. ”

“ The shutter opens and starts the machine taking pictures when the back door of the paying teller's cage is opened half an inch. There is also a hand switch in the line that can be opened so that you can open the door without setting off the camera, if you wish. When the hand switch is closed and the door opened, this is what happens. The shutter on the camera opens, the machine takes five thousand pictures during the next hundredth of a second, and then the shutter closes. Those five thousand exposures will take about five minutes to show at the usual rate of sixteen per second. ”

“ It's a dandy, all right."
"What is special about it?"
"The speed. You know how fast an ordinary movie is taken, don't you? No? Well, it's sixteen exposures per second. The slow pictures are taken sometimes at a hundred and twenty-eight or two hundred and fifty-six exposures per second, and then shown at sixteen. This affair will take half a million pictures per second."
"I didn't know that a film would register with that short an exposure."
"THAT'S slow," replied Casey with a laugh. ”

“ In such a case you would live five minutes in one one-hundredth of a second."
"Naturally, and you would live a year in about seventeen and one-half minutes, and a normal lifespan of seventy years in about twenty hours. You would be as badly off as any common may-fly."
"AGREED, but suppose that you could so regulate the dose of your catalyst that its effect would last for only one one-hundredth of a second. During that short period of time, you would be able to do the work that would ordinarily take you five minutes. ”

“ You don't expect a man who got away with a crime like this to quit operations just because a few flatfeet run around and make a hullabaloo about it, do you? I may be wrong in my assumption, but if I am right, the most important thing is to keep all reference to my name or position out of the press reports."
The cashier hastened up to them.
"Detective-Captain Sturtevant will be here in a few minutes with a photographer and some other men," he said. "Is there anything that we can do in the meantime, Mr. Carnes?"
"I would suggest that Mr. Trier and his guard and Mr. ”
