From "The Hatrack Case" by H.L. Mencken
As I reflected upon the matter it became evident that something would have to be done, for if [John] Chase [head of the Watch and Ward Society] were permitted to get away with this minor assault he would be encouraged to plan worse ones, and, what is more, other wowsers elsewhere would imitate him…
It was accordingly arranged that Hays and I should meet in Boston on Monday morning, April 5 - one week after the suppression of the magazine, and I should there sell a copy of the April issue on the Common, and defy Chase to order my arrest…
[My lawyer Herbert B.] Ehrmann told me that the first business in hand was to take out a peddler's license. It had to be obtained from the Superintendent of Peddlers in the Boston Health Department, and getting it took some time. Meanwhile Ehrmann had made contact with Chase, and tried to induce him to meet me in public and buy a copy of the April issue. It was a difficult job getting his consent. In the past he had always had his own way in Boston, but now an apparently bellicose stranger had come to town to challenge him, with a lawyer of national prominence to brew the legal medicine, and he was considerably alarmed….
He finally agreed, though still very reluctantly, to meet me at 2PM on April 5 at the corner of Park and Tremont – the celebrated Brimstone Corner… I got [there] a little before two o'clock, and found a huge crowd assembled – largely made up, it appeared, of Harvard undergraduates. …I made my way to the agreed rendezvous with some difficulty, for the crowd was very dense, and called for Chase. A youngish man stepped up, said that he was Chase's assistant, and offered to buy the test magazine. When I refused to sell it to him he offered to produce evidence that he was the accredited agent of the Watch and Ward society, but I still refused, and demanded that Chase appear in person.
There was more delay here, but then cries of, "Here he is!" were set up, and he slowly pushed his way toward me. With him were Captain George W. Patterson, chief of the Boston Vice Squad, and a young officer in plain clothes. The actual sale took but a few seconds. Chase identified himself, I offered him a copy of the magazine, he handed me a silver half dollar, I bit it as if to make sure it was a good coin, and Chase said to Patterson, "I order this man's arrest."
Garret then tapped me on the arm and the laborious march to police headquarters began. They were in a little court called Pemberton Square, only four blocks away, but Park Street, which we had to traverse, was crowded …When we finally got into the little headquarters building, I was led to the second floor… and there booked on a charge of violating Chapter 272, Section 28, of the Public General Laws of Massachusetts by possessing and selling obscene literature.
