Perhaps they would never understand why they had been uprooted and sent away from New York. The new transcripts arrived. Impatiently Walton checked through them. In the June tenth transcript, item seventy-one dealt with smallpox statistics for North America 1822-68, and item seventy-two with the tally of antihistamine supply for requisitions for Clinic Three. There was no sign of any of Walton's requests. They had vanished from the record as completely as if they had never been.
