Wilken went to that paper mill in Dalton three times. On each occasion he went as a visitor, of course, and spent inside the mills only the comparatively few minutes it takes the visitor to be ushered from process to process and room to room. If you have ever been conducted through an industrial plant you will realize how little you actually see of processes.... Wilken left the paper mill convinced that he was quite ready to start business. He moved to New York City and set up a studio at 250 West 125th Street. To make everything appear regular he got a job with an advertising firm. He drew pictures of soap and suspenders, and so on, and did rather good work arranging display type for posters. That required only a small part of his time.... First he made the necessary paper. Just how well he worked will be apparent in a few minutes. Then he set about utilizing his book-learned etching and engraving. Little by little he added to his equipment. He never used a camera. In this fact alone he stands conspicuous among counterfeiters. So far as I know, he was the only counterfeiter of any ability at all who did not first photograph the bank note he was about to counterfeit and work from that.... [Then he made one-dollar bills.] I must say to begin with that not all the Wilken bills were detected. Really relatively few of them came into our hands. We took several of the bills to the paper mill in Dalton. They declared the paper to be genuine! We looked back over the production records and checked them against consumption. The two figures balanced! In other words, the United States Mint had used all that had been produced. There seemed to be nothing to do but watch the factory. For six months we hung around and nothing happened. In a month or so Wilken, so we learned later, decided it was time to go to work again. He did. He set up a studio in West Twenty-third Street, New York City, and began to turn out ten dollar bills that passed the tellers of some of the most important banks in America. They even passed the scrutiny of experts in the Treasury Department. I have samples of them here. They are magnificent frauds. I have never seen finer engraving. And to think that he learned this engraving in a public library.[111] And there are many cases in the records of courts and prisons showing a high degree of imagination, ingenuity, constructive intelligence, artistic ability, and careers as long continued in crime as legitimate life careers in physics, engineering, or art.
