A Book for All Readers Part 13

Now each of these is a legitimate reason for the absence of any book not found in its place. By search under each of these heads, _seriatim_, aided by the memory of librarian and a.s.sistants, the missing volume should be readily located, and soon availed of for use.

But in the case of books misplaced by readers, no such tracing out of the whereabouts of any volume is effectual, for the reason that the book may have been (and probably is) put on some shelf where it does not belong.

And the question, where in an extensive collection, a book-hunter admitted to freely range over all the shelves, and a stranger to the minute cla.s.sification of books, has misplaced the missing volumes, is an insoluble problem, except by hunting over or handling the entire library.

In this close practical view of the case we have to add to the long list of the enemies of books, formerly enumerated, those who demand a right to browse (as they term it) among the shelves of a public library, and who displace the books they take down to gratify, it may be, only an idle curiosity. Their offence consists, not in being anxious to see the books, but in preventing others from seeing them, by segregating them where neither librarian nor a.s.sistants may be able to find them, when called for. The whole question is summed up in the statement that the ability to produce library books when called for, depends strictly upon keeping them in their proper place: and this is quite incompatible with promiscuous handling upon the shelves.

The preservation of order is alike in the interest of the reading public, of the librarian and his a.s.sistants, and of the very persons who complain of it as depriving them of library facilities. If library facilities consist in rendering the books in it unfindable, and therefore unavailable to any reader, then the argument for free range of the shelves arrives at a _reductio ad absurdum_. The true library facilities consist in a cla.s.sification and a catalogue which arrange the books in systematic order, and keep them there, save when called into use. Thus, and thus only, can those who resort to a public library for actual research, be a.s.sured of finding what they want, just when they want it.

The time saved to all readers by the sure and steady preservation of an orderly arrangement of the books, is simply incalculable. Multiply the number of volumes out of place by the number of readers who call for them, and you have some idea of the mischief that may be done through the carelessness of a few favored readers, to the whole community of scholars. Of course the considerations here set forth pre-suppose an active and intelligent librarian, and zealous and willing attendants, all ever ready to aid the researches of readers by the most prompt and helpful suggestions, and by dispatch in placing before them what they most need. The one cardinal design of a library--to supply the largest amount of information in the shortest time, is subverted by any disorganizing scheme. If the library be administered on the just principle of "the greatest good to the greatest number," then such individual favoritism should never be allowed.

It may, indeed, be claimed that there is no rule without some valid exceptions; but these exceptions should never be permitted to defeat the cardinal object of the rule--which is to keep every book strictly in its own place. Let the exception be confined to allowing an occasional inspection of the shelves in the company of a library attendant, and there will be no trouble.

But there is another danger, aside from the misplacement of books.

Experience has shown that thefts or mutilations of books have been numerous, in direct proportion to the extension of freedom and opportunity to those frequenting the library. Literary men and book-lovers are frequently book-collectors also; and the temptation to take what is often too loosely considered public property is sometimes yielded to by persons whose character and standing may render them the least suspected. In one of the largest lending libraries in this country, the purloining of books had been carried so far, that the authorities had to provide a wire fence all around the reading room, to keep the readers from access to the shelves. The result was soon seen in the reduction of the number of books stolen from 700 volumes to 300 volumes a year.

After several years' experience of the Astor Library in opening its alcoves to readers (amounting to practical free admission to the shelves to all calling themselves special students) the losses and mutilations of books became so serious, that alcove admissions have been greatly curtailed.

At the Conference of Librarians in London, in 1877, the subject of admission or non-admission to the shelves was discussed with the result that opinions were preponderantly adverse to the free range of the library by readers. It was pointed out that libraries are established and maintained at great cost for serious purposes of reading and study, and that these ends are best subserved by systematic service at a common centre--not by letting the readers scatter themselves about the library shelves. To one speaker who held that every one in a free public library had the right to go to the shelves, and choose his books for himself, it was answered that this was equivalent to saying that it is the idler's right to stroll about in every place devoted to a special business, and interrupt that business at his pleasure.

At the International Conference of 1897, an able defence of open shelves was presented, claiming that it saves much librarians' time in finding books, if readers are allowed to find them for themselves; that thefts and mutilations are inconsiderable; that it makes an appeal to the honor of people to respect the books; that the open shelf system does better educational work; that it is economical by requiring fewer library attendants; that it has grown steadily in favor in America, and that it gives the people the same right in the library which is their own, as the individual has in his own.

On the other hand, it was urged that the arguments for open shelves were all arguments for anarchy; that the readers who want to rummage about for what they want lack proper discipline of the mind; that the number of books lost under it has been very large; that librarians are custodians and conservers, as well as dispensers of books; that all books misplaced are practically lost to the library for the time being; that the open shelf system requires far more s.p.a.ce, and is more expensive; and that, however desirable, its general adoption is utterly impracticable.

The practice of libraries in this particular of administration differs widely, as do the opinions of librarians regarding it. In most colleges and universities free access is allowed; and in some public free libraries, both east and west, the readers are allowed to handle the books on the shelves. This is comparatively safe in the smaller town libraries, where the books are in compact shape, and the unavoidable misplacement can be corrected daily in no long time. The experience of "open shelves" in such collections has been so favorable that their librarians have testified that the losses were insignificant when compared with the great public convenience resulting. But the difficulty and confusion arising from free handling of the books on shelves increases in the direct ratio of the size of the library, until, in an extensive collection, it reaches an intolerable result.

What is encountered continually in enforcing the rule of exclusion from shelves is the almost universal conceit that some reader is ent.i.tled to exemption from such a rule. Explain to him never so courteously that experience has proved that a library is thrown into confusion by such admission; that while he may be careful to replace every book handled in the same spot, nearly all readers are careless, and he will insist that he is the exception, and that he is always careful. That is human nature, the world over--to believe that one can do things better than any one else. But if such importunities prevail, the chances are that books will be misplaced by the very literary expert who has solemnly a.s.serted his infallibility.

On the whole, open shelves may be viewed as an open question. It may be best for small libraries, as to all the books, and for all libraries as to some cla.s.ses of books. But make it general, and order and arrangement are at an end, while chaos takes the place of cosmos. The real student is better served by the knowledge and aid of the librarian, thus saving his time for study, than he can be by ranging about dark shelves to find, among mult.i.tudes of books he does not want, the ones that he actually does want. The business of the librarian, and his highest use, is to bring the resources of the library to the reader. If this takes a hundred or more volumes a day, he is to have them; but to give him the right to throw a library into confusion by "browsing around," is to sacrifice the rights of the public to prompt service, to the whim of one man. Those who think that "browsing" is an education should reflect that it is like any other wandering employment, fatal to fixity of purpose. Like desultory reading of infinite periodicals, it tends rather to dissipate the time and the attention than to inform and strengthen the mind.

In libraries of wide circulation in America, many have open shelves, and many more free access to certain cla.s.ses of books. The Newark Free Library opens all departments except fiction; others open fiction and current literature only. Some libraries, notably in England, have a "safe-guarded" open-shelf system, by which the public are given free range inside the library, while the librarians take post at the outside railing, to charge books drawn, and check off depredations. This method may be styled "every one his own librarian," and is claimed by its originators to work well.

At the Conference of the American Library a.s.sociation in 1899, after discussion, votes were taken, showing 50 librarians in favor of free access to shelves for small libraries, as against only 10 for unrestricted access in large libraries.

The debate brought out curious and instructive facts as to losses of books where free range is allowed. The Denver Public Library lost in one year 955 volumes; the Buffalo Public Library 700 books in seventeen months; the Minneapolis, 300 in a year; and the St. Louis Public Library 1,062 volumes in two years, out of "a very limited open shelf collection." One librarian, estimating the loss of books at $1,000 worth in two years, said the library board were perfectly satisfied, and that "unless we lose $2,500 worth of books a year, the open-shelf system pays in its saving of the expenses of attendance." It does not appear to have occurred to them that a public library owes anything to the public morality, nor that a library losing its books by the thousand, to save the cost of proper management, may be holding out a premium to wholesale robbery.

There is another precaution essential to be observed regarding the more costly and rare possessions of the library. Such books should not be placed upon the shelves with the ordinary books of the collection, but provided for in a repository under lock and key. In a large library, where many hundred volumes of books of especial rarity and value are to be found, a separate room should always exist for this cla.s.s of books.

They will properly include (1) Incunabula, or early printed books; (2) Ma.n.u.scripts, or unique specimens, such as collections of autographs of notable people; (3) Illuminated books, usually written on vellum, or printed in color; (4) Early and rare Americana, or books of American discovery, history, etc., which are scarce and difficult to replace; (5) Any books known to be out of print; and (6) Many costly ill.u.s.trated works which should be kept apart for only occasional inspection by readers.

Where no separate room exists for safe custody of such treasures, they should be provided with a locked book-case or cases, according to their number. When any of these reserved books are called for, they should be supplied to readers under special injunctions of careful handling.

Neglect of precaution may at any time be the means of losing to the library a precious volume. It is easy for an unknown reader who calls for such a rare or costly work, to sign his ticket with a false name, and slip the book under his coat when un.o.bserved, and so leave the library unchallenged. But the librarian or a.s.sistant who supplies the book, if put on his guard by having to fetch it from a locked repository, should keep the reader under observation, unless well known, until the volume is safely returned. Designing and dishonest persons are ever hovering about public libraries, and some of the most dangerous among them are men who know the value of books.

This cla.s.s of reserved books should not be given out in circulation, under any circ.u.mstances. Not only are they subject to injury by being handled in households where there are children or careless persons, who soil or deface them, but they are exposed to the continual peril of fire, and consequent loss to the library. There are often books among these rarities, which money cannot replace, because no copies can be found when wanted. In the Library of Congress, there is a very salutary safe-guard thrown around the most valuable books in the form of a library regulation which provides that no ma.n.u.script whatever, and no printed book of special rarity and value shall be taken out of the library by any person.

This restriction of course applies to Members of Congress, as well as to those officials who have the legal right to draw books from the library.

CHAPTER 12.

THE FACULTY OF MEMORY.

To every reader nothing can be more important than that faculty of the mind which we call memory. The retentive memory instinctively stores up the facts, ideas, imagery, and often the very language found in books, so clearly that they become available at any moment in after life. The tenacity of this hold upon the intellectual treasures which books contain depends largely upon the strength of the impression made upon the mind when reading. And this, in turn, depends much upon the force, clearness and beauty of the author's style or expression. A crude, or feeble, or wordy, redundant statement makes little impression, while a terse, clear, well-balanced sentence fixes the attention, and so fastens itself in the memory. Hence the books which are best remembered will be those which are the best written. Great as is the power of thought, we are often obliged to confess that the power of expression is greater still. When the substance and the style of any writing concur to make a harmonious and strong impression on the reader's mind, the writer has achieved success.

All our study of literature tends to confirm the conviction of the supreme importance of an effective style.

We must set down a good memory as a cardinal qualification of the librarian. This faculty of the mind, in fact, is more important to him than to the members of any other profession whatever, because it is more incessantly drawn upon. Every hour in the day, and sometimes every minute in the hour, he has to recall the names of certain books, the authors of the same, including both their surnames and Christian or forenames, the subjects princ.i.p.ally treated in them, the words of some proverb or quotation, or elegant extract in poetry or prose, the period of time of an author or other noted person, the standard measurements and weights in use, with their equivalents, the moneys of foreign nations and their American values, the time of certain notable events in history, whether foreign or American, ancient or modern, the names and succession of rulers, the prices of many books, the rules observed in the catalogue, both of authors and subjects, the names and schools of great artists, with their period, the meaning in various foreign languages of certain words, the geographical location of any place on the earth's surface, the region of the library in which any book is located--and, in short, an infinitude of items of information which he wants to know out of hand, for his own use, or in aid of Library readers or a.s.sistants. The immense variety of these drafts upon his memory seldom perplexes one who is well endowed with a natural gift in that direction. In fact, it seems actually true of such minds, that the more numerous the calls upon the memory, the more ready is the response.

The metaphysicians have spent many words in attempting to define the various qualities of the mind, and to account for a strong or a weak memory; but after all is said, we find that the surprising difference between different memories is unaccounted for; as unaccountable, indeed, as what differences the man of genius from the mere plodder. The principle of a.s.sociation of ideas is doubtless the leading element in a memory which is not merely verbal. We a.s.sociate in our minds, almost instinctively, ideas of time, or s.p.a.ce, or persons, or events, and these connect or compare one with another, so that what we want is called up or recalled in memory, by a train of endless suggestion. We all have this kind of memory, which may be termed the rational or ideal, as distinguished from the verbal and the local memory. The verbal memory is that which retains in the mind, and reproduces at will what has been said in our hearing by others, or what we have read which has made a marked impression upon us. Thus, some persons can repeat with almost exact accuracy, every word of a long conversation held with another. Others can repeat whole poems, or long pa.s.sages in prose from favorite authors, after reading them over two or three times, and can retain them perfectly in memory for half a century or more. There have even been persons to whom one single reading of any production was sufficient to enable them to repeat it _verbatim_. These instances of a great verbal memory are by no means rare, although some of them appear almost incredible. John Locke tells us of the French philosopher Pascal, that he never forgot anything of what he had done, said, or thought, in any part of his natural life.

And the same thing is recorded of that great scholar of Holland, Hugo Grotius.

The mathematician Euler could repeat the Aeneid of Virgil from beginning to end, containing nearly nine thousand lines. Mozart, upon hearing the _Miserere_ of Allegri played in the Sistine Chapel at Rome, only once, went to his hotel, and wrote it all down from memory, note for note.

Cardinal Mezzofanti both wrote and spoke thirty languages, and was quite familiar with more than a hundred. He said that if he once heard the meaning of a word in any language, he never forgot it. Yet he was of the opinion, that although he had twenty words for one idea, it was better to have twenty ideas for one word; which is no doubt true, so far as real intellectual culture is concerned. Lord Macaulay, who had a phenomenal memory, said that if all the copies of Milton's Paradise Lost were to be destroyed, he could reproduce the book complete, from memory. In early life he was a great admirer of Walter Scott's poetry, and especially the "Lay of the Last Minstrel", and could repeat the whole of that long poem, more than six hundred lines, from memory. And at the age of fifty-seven he records--"I walked in the portico, and learned by heart the n.o.ble fourth act of the Merchant of Venice. There are four hundred lines. I made myself perfect master of the whole in two hours." It was said of him that every incident he heard of, and every page he read, "a.s.sumed in his mind a concrete spectral form."

But the memory for names and words has been sometimes called the lowest form of memory. Persons of defective or impaired intellect frequently have strong and retentive verbal memories. Mrs. Somerville records the case of an idiot who could repeat a whole sermon _verbatim_, after once hearing it, but who was stupid and ignorant as to every thing else. And there are many instances in the books to the same effect.

Another kind of memory may be called, for want of a better name, the local memory. A person who has this strongly developed, if he once goes to a place, whether a room, or a street in a city, or a road in any part of the country, knows the way again, and can find it by instinct ever after. In the same way any one gifted with this almost unerring sense of locality, can find any book on any shelf in any part of a library where he has once been. He knows, in like manner, on which side of the page he saw any given pa.s.sage in a book, which impressed him at the time, although he may never have had the volume in his hand more than once. He may not remember the number of the page, but he is sure of his recollection that it was the left or the right hand one, as the case may be, and this knowledge will abridge his labor and time in finding it again by just one half. This local memory is invaluable to a librarian or an a.s.sistant in shortening the labor of finding things. If you have a good local memory, you can, in no long time, come to dispense with the catalogue and its shelf-marks or cla.s.sification marks, almost entirely, in finding your books. Although this special gift of memory--the sense of locality--is unquestionably a lower faculty of the mind than some others named, and although there are illiterate persons who can readily find and produce any books in a library which have often pa.s.sed through their hands, yet it is a faculty by no means to be despised. It is one of the labor-saving, time-saving gifts, which should be welcomed by every librarian. The time saved from searching the catalogues for location-marks of the outside of books, will enable him to make many a research in their inside. This faculty, of course, is indefinitely strengthened and improved by use--and the same is true of the other branches of the sense which we call memory. The oftener you have been to any place, the better you know the way. The more frequently you have found and produced a given book from its proper receptacle, the easier and the quicker will be your finding it again.

Another faculty or phase of memory is found in the ability to call up the impression made by any object once seen by the eye, so as to reproduce it accurately in speech or writing. This may be termed the intuitive memory.

There are many applications or ill.u.s.trations of this faculty. Thus, for example, you see a book on some shelf in your library. You take in its size, its binding, both the material and the color, and its t.i.tle as lettered on the back. All this you absorb with one glance of the eye. You remember it by the principle of a.s.sociation--that is, you a.s.sociate with that particular book, in connection with its t.i.tle, a certain dimension, color, and style of binding. Now, when you have occasion to look up that special volume again, you not only go, aided by your memory of locality, to the very section and shelf of the library where it belongs, but you take with you instinctively, your memory or mental image of the book's appearance. Thus, you perhaps distinctly remember (1) that it was an octavo, and your eye in glancing along the shelf where it belongs, rejects intuitively all the duodecimos or books of lesser size, to come to the octavos. (2) Then you also remember that it was bound in leather, consequently you pa.s.s quickly by all the cloth bound volumes on the shelf. (3) in the third place you know that its color was red; and you pay no attention whatever to books of any other color, but quickly seize your red leather-bound octavo, and bear it off to the reading-room in triumph. Of course there are circ.u.mstances where this quick operation of the faculties of memory and intuition combined, would not be so easy. For example, all the books (or nearly all) on a given shelf might be octavos; or they might all be leather-bound; or a majority of them with red backs; and the presence of one or more of these conditions would eliminate one or more of the facilities for most rapidly picking out the book wanted.

But take a pile of books, we will say returned by many readers, on the library counter. You are searching among them for a particular volume that is again wanted. There is no order or arrangement of the volumes, but you distinctly remember, from having handled it, its size both as to height and thickness, its color, and how it was bound. You know it was a thin 12mo. in green cloth binding. Do you, in your search, take up every book in that ma.s.s, to scrutinize its t.i.tle, and see if it is the one you seek? By no means. You quickly thrust aside, one by one, or by the half-dozen, all the volumes which are not green, cloth-bound, thin duodecimos, without so much as glancing at them. Your special volume is quickly found among hundreds of volumes, and your faculty of memory and intuition has saved you perhaps a quarter of an hour of valuable time, which, without that faculty, might have been wasted in search.

Again, another circ.u.mstance which might intervene to diminish the frequency of application of the memory referred to, as to the physical features or appearance of a book sought for, is where the shelf-arrangement is alphabetical, by authors' names, or by the names of the subjects of the books, if it is an alphabet of biographies. Here, the surest and the quickest guide to the book is of course the alphabetical order, in which it must necessarily be found.

This memory of the aspect of any object once looked at, is further well ill.u.s.trated in the very varied facilities for the spelling of words found in different persons. Thus, there are people who, when they once see any word (we will say a proper name) written or printed, can always afterwards spell that word unerringly, no matter how uncommon it may be.

The mental retina, so to speak, receives so clear and exact an impression of the form of that word from the eye, that it retains and reproduces it at will.

But there are others, (and among them persons of much learning in some directions) upon whom the form or orthography of a word makes little or no impression, however frequently it meets the eye in reading. I have known several fine scholars, and among them the head of an inst.i.tution of learning, who could not for the life of them spell correctly; and this infirmity extended even to some of the commonest words in the language.

Why this inapt.i.tude on the part of many, and this extraordinary facility on the part of others, in the memorizing faculty, is a phenomenon which may be noted down, but not solved. That vivid mental picture which is seen by the inward eye of the person favored with a good memory, is wholly wanting, or seen only dimly and rarely in the case of one who easily forgets.

So vital and important is memory, that it has been justly denominated by the German philosopher, Kant, "the most wonderful of our faculties."

Without it, the words of a book would be unintelligible to us, since it is memory alone which furnishes us with the several meanings to be attached to them.

Some writers on the science of mind a.s.sert that there is no such thing with any of us as absolutely forgetting anything that has once been in the mind. All mental activities, all knowledge which ever existed, persists. We never wholly lose them, but they become faint and obscure.

One mental image effaces another. But those which have thus disappeared may be recalled by an act of reminiscence. While it may sometimes be impossible to recover one of them at the moment when wanted, by an act of voluntary recollection, some a.s.sociation may bring it unexpectedly and vividly before us. Memory plays us many strange tricks, both when we wake and when we dream. It revives, by an involuntary process, an infinite variety of past scenes, faces, events, ideas, emotions, pa.s.sions, conversations, and written or printed pages, all of which we may have fancied had pa.s.sed forever from our consciousness.

The aids to memory supposed to be furnished by the various mnemonic systems may now be briefly considered. These methods of supplying the defects of a naturally weak memory, or of strengthening a fairly good one, are one and all artificial. This might not be a conclusive objection to them, were they really effective and permanent helps, enabling one who has learned them to recall with certainty ideas, names, dates, and events which he is unable to recall by other means. Theory apart, it is conceded that a system of memorizing which had proved widely or generally successful in making a good memory out of a poor one, would deserve much credit. But experience with these systems has as yet failed to show, by the stern test of practical utility, that they can give substantial (and still less permanent) aid in curing the defects of memory. Most of the systems of mnemonics that have been invented are constructed on the principle of locality, or of utilizing objects which appeal to the sight. There is nothing new in these methods, for the principle is as old as Simonides, who lived in the fifth century before Christ, and who devised a system of memorizing by locality. One of the most prevalent systems now taught is to select a number of rooms in a house (in the mind's eye, of course) and divide the walls and the floors of each room into nine equal parts or squares, three in a row. Then

"On the front wall--that opposite the entrance of the first room--are the units, on the right-hand wall the tens, on the left hand the twenties, on the fourth wall the thirties, and on the floor the forties. Numbers 10, 20, 30, and 40, each find a place on the roof above their respective walls. One room will thus furnish 50 places, and ten rooms as many as 500, while 50 occupies the centre of the roof. Having fixed these clearly in the mind, so as to be able readily and at once to tell the exact position of each place or number, it is then necessary to a.s.sociate with each of them some familiar object (or symbol) so that the object being suggested, its place may be instantly remembered, or when the place is before the mind, its object may immediately spring up. When this has been done thoroughly, the objects can be run over in any order from beginning to end, or from end to beginning, or the place of any particular one can at once be given. All that is further necessary is to a.s.sociate the ideas we wish to remember with the objects in the various places, by which means they are readily remembered, and can be gone over in any order. In this way, one may learn to repeat several hundred disconnected words or ideas in any order, after hearing them only once."

This rather complicated machinery for aiding the memory is quite too mechanical to commend itself to any one accustomed to reflect or to take note of his own mental processes. Such an elaborate system crowds the mind with a lot of useless furniture, and hinders rather than helps a rational and straightforward habit of memorizing. It too much resembles the feat of trying to jump over a wall by running back a hundred or more yards to acquire a good start or momentum. The very complication of the system is fitted to puzzle rather than to aid the memory. It is based on mechanical or arithmetical a.s.sociations--not founded on nature, and is of very small practical utility. It does not strengthen or improve the habit of memorizing, which should always be based upon close attention, and a logical method of cla.s.sifying, a.s.sociating, and a.n.a.lyzing facts or ideas.

Lord Bacon, more than two centuries ago, wisely characterized mnemonic systems as "barren and useless." He wrote, "For immediately to repeat a mult.i.tude of names or words once repeated before, I esteem no more than rope-dancing, antic postures, and feats of activity; and, indeed, they are nearly the same thing, the one being the abuse of the bodily, as the other is of mental powers; and though they may cause admiration, they cannot be highly esteemed."

In fact, these mnemonical systems are only a kind of crutches, sometimes useful to people who cannot walk, but actual impediments to those having the use of their limbs, and who by proper exercise can maintain their healthy and natural use indefinitely.

I have given you an account of one of these artificial systems of memory, or systems of artificial memory, as you may choose to call them. There have been invented more than one hundred different systems of mnemonics, all professing to be invaluable, and some claiming to be infallible. It appears to be a fatal objection to these memory-systems that they subst.i.tute a wholly artificial a.s.sociation of ideas for a natural one.

The habit of looking for accidental or arbitrary relations of names and things is cultivated, and the power of logical, spontaneous thought is injured by neglecting essential for unessential relations. These artificial a.s.sociations of ideas work endless mischief by crowding out the natural ones.

How then, you may ask, is a weak memory to be strengthened, or a fairly good memory to be cultivated into a better one? The answer is, by constant practice, and for this the vocation of a librarian furnishes far more opportunities than any other. At the basis of this practice of the memory, lies the habit of attention. All memory depends upon the strength or vividness of the impression made upon the mind, by the object, the name, the word, the date, which is sought to be remembered. And this, in turn, depends on the degree of attention with which it was first regarded. If the attention was so fixed that a clear mental image was formed, there will be no difficulty in remembering it again. If, on the other hand, you were inattentive, or listless, or pre-occupied with other thoughts, when you encountered the object, your impression of it would be hazy and indistinct, and no effort of memory would be likely to recall it.
