Turning the further pages of my atlas I came upon an elaborately illustrated directory of the uniforms and insignia of the various military and civil ranks and classes. As I had already anticipated, I found that any citizen in Berlin could immediately be placed in his proper group and rank by his clothing, which was prescribed with military exactness. Various fabrics and shades indicated the occupational grouping while trimmings and insignia distinguished the ranks within the groups. In all there were many hundreds of distinct uniforms. Two groups alone proved exceptions to this iron clad rule; Royalty and free women were permitted to dress as they chose and were restricted only in that they were forbidden to imitate the particular uniforms of other groups. I next investigated the contents of Armstadt's desk. My most interesting find was a checkbook, with receipts and expenditures carefully recorded on the stubs. From this I learned that, as Armstadt, I was in receipt of an income of five thousand marks, paid by the Government. I did not know how much purchasing value that would amount to, but from the account book I saw that the expenses had not equalled a third of it, which explained why there was a bank balance of some twenty thousand marks. Clearly I would need to master the signature of Karl Armstadt so I searched among the papers until I found a bundle of returned decks. Many of the larger checks had been made out to "Katrina," others to the "Master of Games,"--evidently to cover gambling losses. The smaller checks, I found by reference to the stubs, were for ornaments or entertainment that might please a woman. The lack of the more ordinary items of expenditure was presently made clear by the discovery of a number of punch marked cards. For intermittent though necessary expenses, such as tonsorial service, clothing and books. For the more constant necessities of life, such as rent, food, laundry and transportation, there was no record whatever; and I correctly assumed that these were supplied without compensation and were therefore not a matter of personal choice or permissible variation. Of money in its ancient form of metal coins and paper, I found no evidence. ~3~ In my mail the next morning I found a card signed by Lieut. Forrester of the hospital staff. It read: "The bearer, Karl Armstadt, has recently suffered from gas poisoning while defending the mines beneath enemy territory. This has affected his memory. If he is therefore found disobeying any ruling or straying beyond his permitted bounds, return him to his apartment and call the Hospital for Complex Gas Cases." It was evidently a very kindly effort to protect a man whose loss of memory might lead him into infractions of the numerous rulings of German life. With this help I became ambitious to try the streets of Berlin alone. The notice from the tailor afforded an excuse.
