The memories were there, all right. He could sense them, floating in some sort of mental limbo, just beyond the grasp of his conscious mind, like the memories of a dream after one has awakened. Each time he would try to reach into the darkness to grasp one of the pieces, it would shatter into smaller bits. The big patterns were too fragile to withstand the direct probing of his conscious mind, and even the resulting fragments did not want to hold still long enough to be analyzed. And, while a part of his mind probed frantically after the elusive particles of memory, another part of it watched the process with semi-detached amusement. He had always known there were holes in his memory (_Always? Don't kid yourself, pal!_), but it was disconcerting to find an area that was as full of holes as a used machine-gun target. The whole fabric had been punched to bits. No man's memory is completely available at any given time. Whatever the recording process is, however completely every bit of data may be recorded during a lifetime, much of it is unavailable. It may be incompletely cross-indexed, or, in some instances, labeled DO NOT SCAN. Or, metaphorically, the file drawer may be locked. It may be that, in many cases, if a given bit of data remains unscanned for a long enough period, it fades into illegibility, never reinforced by the scanning process. Sensory data, coming in from the outside world as it does, is probably permanent. But the thought patterns originating within the mind itself, the processes that correlate and cross-index and speculate on and hypothesize about the sensory data, these are much more fragile. A man might glance once through a Latin primer and have each and every page imprinted indelibly on his recording mechanism and still be unable to make sense out of _Nauta in cubitu cum puella est_. Sometimes a man is aware of the holes in his memory. ("What _was_ the name of that fellow I met at Eddie's party? Can't remember it for the life of me.") At other times, a memory may lay dormant and completely unremembered, leaving no apparent gap, until a tag of some kind brings it up. ("That girl with the long hair reminds me of Suzie Blugerhugle. My gosh! I haven't thought of her in years!") Both factors seemed to be operating in Bart Stanton's mind at this time.
