If the universe consisted of but two bodies,--say, the sun and a planet,--the motion would be simplicity itself; the planet would describe an exact ellipse about the sun, and this...o...b..t would never change in form, size, or position. With the addition of only one more body, the problem at once becomes so much more difficult as to be practically insoluble; indeed, the "problem of the three bodies" has been attacked by astronomers for years without the discovery of any general formula to express the resulting motions. For the actually existing system of many planets with their satellites and countless asteroids, only an approximation is possible. The actual motions as observed and measured from year to year are most complex. Can these be completely accounted for by the mutual attractions of the bodies, according to the law of gravitation as enunciated by Sir Isaac Newton? In Newcomb's words, "Does any world move otherwise than as it is attracted by other worlds?" Of course, Newcomb has not been the only astronomer at work on this problem, but it has been his life-work and his contributions to its solution have been very noteworthy.

It is difficult to make the ordinary reader understand the obstacles in the way of such a determination as this. Its two elements are, of course, the mapping out of the lines in which the bodies concerned actually do move and the calculations of the orbits in which they ought to move, if the accepted laws of planetary motion are true. The first involves the study of thousands of observations made during long years by different men in far distant lands, the discussion of their probable errors, and their reduction to a common standard. The latter requires the use of the most refined methods of mathematical a.n.a.lysis; it is, as Newcomb says, "of a complexity beyond the powers of ordinary conception." In works on celestial mechanics a single formula may fill a whole chapter.

This problem first attracted Newcomb's attention when a young man at Cambridge, when by a.n.a.lysis of the motions of the asteroids he showed that the orbits of these minor planets had not, for several hundred thousand years past, intersected at a single point, and that they could not, therefore, have resulted, during that period, from the explosion of a single large body, as had been supposed.

Later, when Newcomb's investigations along this line had extended to the major planets and their satellites, a curious anomaly in the moon's motion made it necessary for him to look for possible observations made long before those hitherto recorded. The accepted tables were based on observations extending back as far as 1750, but Newcomb, by searching the archives of European observatories, succeeded in discovering data taken as early as 1660, not, of course, with such an investigation as this in view, but chiefly out of pure scientific curiosity. The reduction of such observations, especially as the old French astronomers used apparent time, which was frequently in error by quarter of an hour or so, was a matter of great difficulty. The ancient observer, having no idea of the use that was to be made of his work, had supplied no facilities for interpreting it, and "much comparison and examination was necessary to find out what sort of an instrument was used, how the observations were made, and how they should be utilized for the required purpose." The result was a vastly more accurate lunar theory than had formerly been obtained.

During the period when Newcomb was working among the old papers of the Paris Observatory, the city, then in possession of the Communists, was beset by the national forces, and his studies were made within hearing of the heavy siege guns, whose flash he could even see by glancing through his window.

Newcomb's appointment as head of the Nautical Almanac office greatly facilitated his work on the various phases of this problem of planetary motions. Their solution was here a legitimate part of the routine work of the office, and he had the aid of able a.s.sistants,--such men as G.W. Hill, who worked out a large part of the theory of Jupiter and Saturn, and Cleveland Keith, who died in 1896, just as the final results of his work were being combined. In connection with this work Professor Newcomb strongly advocated the unification of the world's time by the adoption of an international meridian, and also international agreement upon a uniform system of data for all computations relating to the fixed stars. The former still hangs fire, owing to mistaken "patriotism"; the latter was adopted at an international conference held in Paris in 1896, but after it had been carried into effect in our own Nautical Almanac, professional jealousies brought about a modification of the plan that relegated the improved and modernized data to an appendix.

Professor Newcomb's retirement from active service made the continuance of his great work on an adequate scale somewhat problematical, and his data on the moon's motion were laid aside for a time until a grant from the newly organized Carnegie Inst.i.tution in 1903 enabled him to employ the necessary a.s.sistance, and the work has since gone forward to completion.

What is the value of such work, and why should fame be the reward of him who pursues it successfully? Professor Newcomb himself raises this question in his "Reminiscences," and without attempting to answer it directly he notes that every civilized nation supports an observatory at great annual expense to carry on such research, besides which many others are supported by private or corporate contributions. Evidently the consensus of public opinion must be that the results are worth at least a part of what they cost. The question is included in the broader one of the value of all research in pure science. Speaking generally, the object of this is solely to add to the sum of human knowledge, although not seldom some application to man's physical needs springs unexpectedly from the resulting discoveries, as in the case of the dynamo or that of wireless telegraphy. Possibly a more accurate description of the moon's motion is unlikely to bring forth any such application, but those who applaud the achievements of our experts in mathematical astronomy would be quick to deny that their fame rests on any such possibility.

Pa.s.sing now to Professor Newcomb's "recreation," as he called, it,--political economy, we may note that his contributions to it were really voluminous, consisting of papers, popular articles and several books, including "The A B C of Finance" (1877) and "Principles of Political Economy" (1886). Authorities in the science never really took these as seriously as they deserved, possibly because they regarded Professor Newcomb as scarcely orthodox. Some of his distinctions, however, are of undoubted value and will live; for instance, that between the fund and the flux of wealth, on which he insists in his treatises on finance.

As to Professor Newcomb's single excursion into fiction, a romance ent.i.tled "His Wisdom the Defender," it is perhaps sufficient to say that, like everything he attempted, it is at least worth notice. It is a sort of cross between Jules Verne and Bulwer Lytton's "Coming Race."

Professor Newcomb's mind was comprehensive in its activity. One might have thought that an intellect occupied to the last in carrying out one of the most stupendous tasks ever attempted by a mathematical astronomer would have had little time or little energy left for other things; but Newcomb took his rest and pleasure in popular articles and interviews. Only a short time before his death he published an essay on aeronautics that attracted wide attention, drawing the conclusions that the aeroplane can never be of much use either as a pa.s.senger-carrier or in war, but that the dirigible balloon may accomplish something within certain lines, although it will never put the railways and steamships out of business. In particular, he treated with unsparing ridicule the panic fear of an aerial invasion that so lately seized upon our transatlantic cousins.

Personally, Newcomb was an agreeable companion and a faithful friend. His success was due largely to his tenacity of purpose. The writer's only personal contact with him came through the "Standard Dictionary,"--of whose definitions in physical science Newcomb had general oversight. On one occasion he came into the office greatly dissatisfied with the definition that we had framed for the word "magnet."--a conception almost impossible to define in any logical way. We had simply enumerated the properties of the thing,--a course which in the absence of authoritative knowledge of their causes was the only rational procedure. But Newcomb's mind demanded a logical treatment, and though he must have seen from the outset that this was a forlorn hope, his tenacity of purpose kept him, pencil in hand, writing and erasing alternately for an hour or more.

Finally he confessed that he could do no better than the following pair of definitions,--"_Magnet_, a body capable of exerting magnetic force," and "_Magnetic Force_, the force exerted by a magnet." With a hearty laugh at this beautiful _circulus in definiendo_ he threw down his pencil, and the imperfect and illogical office definition was accepted.

Logical as he was, however, he was in no sense bound by convention. His economics, as has been said, was often unorthodox, and even in his mathematical text-books he occasionally shocked the hide-bound. I well remember an interesting discussion among members of the Yale mathematical faculty just after the appearance of Newcomb's text-book of geometry, in which he was unsparingly condemned by some because he a.s.sumed in certain elementary demonstrations that geometrical figures could be removed from the paper, turned over and laid down again,--the so-called "method of superposition," now generally regarded as quite allowable. Of course, a figure can be treated in this way only in imagination and for this season, probably, the method was not employed by Euclid. Its use, however, leads always to true results, as anyone may see; and it was quite characteristic of Professor Newcomb that he should have taken it up, not having the fear of the Greek geometers before him.

Such was Newcomb; it will be long before American science sees his equal.

Mathematical genius is like an automobile,--it is looked upon in two opposing fashions as one has it or has it not. A noted educator not long ago announced his belief that the possession of a taste for mathematics is an exact index of the general intellectual powers. Not much later, another eminent teacher a.s.serted that mathematical ability is an exotic,--that one may, and often does, possess it who is in other respects practically an imbecile. This is scarcely a subject in which a single ill.u.s.tration decides, but surely Newcomb's career justifies the former opinion rather than the latter; the amount and kind of his mental abilities along all lines seemed to run parallel to his mathematical genius, to resemble it in quant.i.ty and in kind.

The great volumes of astronomical tables without which no astronomer may now venture upon a computation are his best monument; yet the general reader will longer remember, perhaps, the lucid expositor, the genial essayist, the writer of one of the most readable autobiographies of our day.

THE COMPANIONSHIP OF BOOKS[5]

[5] Read before the Pacific Northwest Library a.s.sociation, June, 1910.

Are books fitted to be our companions? That depends. You and I read them with pleasure; others do not care for them; to some the reading of any book at all is as impossible as the perusal of a volume in Old Slavonic would be to most of us. These people simply do not read at all. To a suggestion that he supplement his usual vacation sports by reading a novel, a New York police captain--a man with a common school education--replied, "Well, I've never read a book yet, and I don't think I'll begin now." Here was a man who had never read a book, who had no use for books, and who could get along perfectly well without them. He is not a unique type. Hundreds of thousands of our fellow citizens might as well be quite illiterate, so far as the use that they make of their ability to read is concerned. These persons are not all uneducated; they possess and are still acquiring much knowledge, but since leaving school they have acquired it chiefly by personal experience and by word of mouth. Is it possible that they are right? May it be that to read books is unnecessary and superfluous?

There has been some effort of late to depreciate the book--to insist on its inadequacy and on the impracticality of the knowledge that it conveys.

"Book-learning" has always been derided more or less by so-called "practical men". A recent series of comic pictures in the newspapers makes this clear. It is about "Book-taught Bilkins". Bilkins tries to do everything by a book. He raises vegetables, builds furniture, runs a chicken farm, all by the directions contained in books, and meets with ignominious failure. He makes himself, in fact, very ridiculous in every instance and thousands of readers laugh at him and his absurd books. They inwardly resolve, doubtless, that they will be practical and will pay no attention to books. Are they right? Is the information contained in books always useless and absurd, while that obtained by experience or by talking to one's neighbor is always correct and valuable?

Many of our foremost educators are displeased with the book. They are throwing it aside for the lecture, for laboratory work, for personal research and experiment. Does this mean that the book, as a tool of the teacher, will have to go?

What it all certainly does mean is that we ought to pause a minute and think about the book, about what it does and what it can not do. This means that we ought to consider a little the whole subject of written as distinguished from spoken language. Why should we have two languages--as we practically do--one to be interpreted by the ear and the other by the eye? Could we or should we abandon either? What are the advantages and what the limitations of each? We are so accustomed to looking upon the printed page, to reading newspapers, books, and advertis.e.m.e.nts, to sending and receiving letters, written or typewritten, that we are apt to forget that all this is not part of the natural order, except in the sense that all inventions and creations of the human brain are natural. Written language is a conscious invention of man; spoken language is a development, shaped by his needs and controlled by his sense of what is fitting, but not at the outset consciously devised.

We are apt to think of written language as simply a means of representing spoken language to the eye; but it is more than this; originally, at least in many cases, it was not this at all. The written signs represented not sounds, but ideas themselves; if they were intended to correspond directly with anything, it was with the rude gestures that signified ideas and had nothing to do with their vocal expression. It was not until later that these written symbols came to correspond to vocal sounds and even to-day they do so imperfectly; languages that are largely phonetic are the exception. The result is, as I have said, that we have two languages--a spoken and a written. What we call reading aloud is translation from the written to the spoken tongue; while writing from dictation is translation from the spoken to the written. When we read, as we say, "to ourselves,"

we sometimes, if we are not skilful, p.r.o.nounce the spoken words under our breath, or at least form them with our vocal organs. You all remember the story of how the Irishman who could not read made his friend stop up his ears while reading a letter aloud, so that he might not hear it. This anecdote, like all good comic stories, has something in it to think about.

The skilful reader does not even imagine the spoken words as he goes. He forgets, for the moment, the spoken tongue and translates the written words and phrases directly into the ideas for which they stand. A skilful reader thus takes in the meaning of a phrase, a sentence, even of a paragraph, at a glance. Likewise the writer who sets his own thoughts down on paper need not voice them, even in imagination; he may also forget all about the spoken tongue and spread his ideas on the page at first hand.

This is not so common because one writes slower than he speaks, whereas he reads very much faster. The swift reader could not imagine that he was speaking the words, even if he would; the pace is too incredibly fast.

Our written tongue, then, has come to be something of a language by itself. In some countries it has grown so out of touch with the spoken tongue that the two have little to do with each other. Where only the learned know how to read and write, the written language takes on a learned tinge; the popular spoken tongue has nothing to keep it steady and changes rapidly and unsystematically. Where nearly all who speak the language also read and write it, as in our own country, the written tongue, even in its highest literary forms, is apt to be much more familiar and colloquial, but at the same time the written and the spoken tongue keep closer together. Still, they never accurately correspond. When a man "talks like a book," or in other words, uses such language that it could be printed word for word and appear in good literary form, we recognize that he is not talking ordinary colloquial English--not using the normal spoken language. On the other hand, when the speech of a southern negro or a down-east Yankee is set down in print, as it so often is in the modern "dialect story," we recognize at once that although for the occasion this is written language, it is not normal literary English.

It is most desirable that the two forms of speech shall closely correspond, for then the written speech gets life from the spoken and the spoken has the written for its governor and controller; but it is also desirable that each should retain more or less individuality, and fortunately it is almost impossible that they should not do so.

We must not forget, therefore, that our written speech is not merely a way of setting down our spoken speech in print. This is exactly what our friends the spelling reformers appear to have forgotten. The name that they have given to what they propose to do, indicates this clearly. When a word as written and as spoken have drifted apart, it is usually the spoken word that has changed. Reform, therefore, would be accomplished by restoring the old spoken form. Instead of this, it is proposed to change the written form. In other words, the two languages are to be forced together by altering that one of them that is by its essence the most immutable. Where the written word has been corrupted as in spelling "guild" for "gild," the adoption of the simpler spelling is a reform; otherwise, not.

Now is the possession of two languages, a spoken and a written, an advantage or not? With regard to the spoken tongue, the question answers itself. If we were all deaf and dumb, we could still live and carry on business, but we should be badly handicapped. On the other hand, if we could neither read nor write, we should simply be in the position of our remote forefathers or even of many in our own day and our own land. What then is the reasons for a separate written language, beyond the variety thereby secured, by the use of two senses, hearing and sight, instead of only one?

Evidently the chief reason is that written speech is eminently fitted for preservation. Without the transmittal of ideas from one generation to another, intellectual progress is impossible. Such transmittal, before the invention of writing, was effected solely by memory. The father spoke to the son, and he, remembering what was said, told it, in turn, to the grandson. This is tradition, sometimes marvellously accurate, but often untrustworthy. And as it is without check, there is no way of telling whether a given fact, so transmitted, is or is not handed down faithfully.

Now we have the phonograph for preserving and accurately reproducing spoken language. If this had been invented before the introduction of written language, we might never have had the latter; as it is, the device comes on the field too late to be a compet.i.tor with the book in more than a very limited field. For preserving particular voices, such as those of great men, or for recording intonation and p.r.o.nunciation, it fills a want that writing and printing could never supply.

For the long preservation of ideas and their conveyance to a human mind, written speech is now the indispensable vehicle. And, as has been said, this is how man makes progress. We learn in two ways: by undergoing and reflecting on our own experiences and by reading and reflecting on those of others. Neither of these ways is sufficient in itself. A child bound hand and foot and confined in a dark room would not be a fit subject for instruction, but neither would he reach a high level if placed on a desert island far from his kind and forced to rely solely on his own experiences.

The experiences of our forebears, read in the light of our own; the experiences of our forebears, used as a starting-point from which we may move forward to fresh fields--these we must know and appreciate if we are to make progress. This means the book and its use.

Books may be used in three ways--for information, for recreation, for inspiration. There are some who feel inclined to rely implicitly on the information that is to be found in books--to believe that a book can not lie. This is an unfortunate state of mind. The word of an author set down in print is worth no more than when he gives it to us in spoken language--no more and no less. There was, to be sure, a time when the printed word implied at least care and thoughtfulness. It is still true that the book implies somewhat more of this than the newspaper, but the difference between the two is becoming unfortunately less. Now a wrong record, if it purports to be a record of facts, is worse than none at all.

The man who desires to know the distance between two towns in Texas and is unable to find it in any book of reference may obtain it at the cost of some time and trouble; but if he finds it wrongly recorded, he accepts the result and goes away believing a lie. If we are to use books for information, therefore, it is of the utmost consequence that we know whether the information is correct or not. A general critical evaluation of all literature, even on this score alone, without going into the question of literary merit, is probably beyond the possibilities, although it has been seriously proposed. Some partial lists we have, and a few lists of those lists, so that we may know where to get at them. There are many books about books, especially in certain departments of history, technology, or art, but no one place to which a man may go, before he begins to read his book, to find out whether he may believe what he reads in it. This is a serious lack, especially as there is more than one point of view. Books that are of high excellence as literature may not be at all accurate. How shall the boy who hears enthusiastic praise of Prescott's histories and who is spellbound when he reads them know that the results of recent investigation prove that those histories give a totally incorrect idea of Mexico and Peru? How is the future reader of Dr. Cook's interesting account of the ascent of Mount McKinley to know that it has been discredited? And how is he to know whether other interesting and well-written histories and books of travel have not been similarly proved inaccurate? At present, there is no way except to go to one who knows the literature of the subject, or to read as many other books on the subject as can be obtained, weighing one against the other and coming to one's own conclusions. Possibly the public library may be able to help. Mr. Charles F. Lummis of the Los Angeles library advocates labelling books with what he calls "Poison Labels" to warn the reader when they are inaccurate or untrustworthy. Most librarians have hesitated a little to take so radical a step as this, not so much from unwillingness to a.s.sume the duty of warning the public, as from a feeling that they were not competent to undertake the critical evaluation of the whole of the literature of special subjects. The librarian may know that this or that book is out of date or not to be depended on, but there are others about which he is not certain or regarding which he must rely on what others tell him. And he knows that expert testimony is notoriously one-sided. It is this fear of acting as an advocate instead of as a judge that has generally deterred the librarian from labelling his books with notes of advice or warning.

There is, however, no reason why the librarian should take sides in the matter. He may simply point out to the reader that there are other books on the same subject, written from different points of view, and he may direct attention to these, letting the reader draw his own conclusions.

There is probability that the public library in the future will furnish information and guidance of this kind about books, more than it has done in the past.

And here it may be noted in pa.s.sing that the library is coming out of its sh.e.l.l. It no longer holds itself aloof, taking good care of its books and taking little care of the public that uses them. It is coming to realize that the man and the book are complementary, that neither is much without the other, and that to bring them together is its duty. It realizes also that a book is valuable, not because it is so much paper and ink and thread and leather, but because it records and preserves somebody's ideas.

It is the projection of a human mind across s.p.a.ce and across time and where it touches another human mind those minds have come into contact just as truly and with as valuable results as if the bodies that held them stood face to face in actual converse. This is the miracle of written speech--a miracle renewed daily in millions of places with millions of readers.

We have, in the modern library, the very best way of perpetuating such relations as this and of ensuring that such as are preserved shall be worth preserving. When the ancients desired to make an idea carry as far as possible, they saw to the toughness and strength of the material object const.i.tuting the record; they cut it in stone or cast it in metal, forgetting that all matter is in a state of continual flux and change; it is the idea only that endures. Stone and metal will both one day pa.s.s away and unless some one sees fit to copy the inscription on a fresh block or tablet, the record will be lost. It is, then, only by continual renewal of its material basis that a record in written language can be made to last, and there is no reason why this renewal should not take place every few years, as well as every few centuries. There is even an advantage in frequent renewal; for this ensures that the value of the record shall be more frequently pa.s.sed upon and prevents the preservation of records that are not worth keeping. This preservation by frequent renewal is just what is taking place with books; we make them of perishable materials; if we want to keep them, we reprint them; otherwise they decay and are forgotten.

We should not forget that by this plan the reader is usually made the judge of whether a book is worth keeping. Why do we preserve by continual reprinting Shakespeare and Scott and Tennyson and Hawthorne? The reprinting is done by publishers as a money-making scheme. It is profitable to them because there is a demand for those authors. If we cease to care for them and prefer unworthy writers, Shakespeare and Scott will decay and be forgotten and the unworthy ones will be preserved. Thus a great responsibility is thrown upon readers; so far they have judged pretty well.

Just now, however, we are confining ourselves to the use of books for information; and here there is less preservation than elsewhere.

Especially in science, statements and facts quickly become out of date; here it is not the old but the new that we want--the new based on the accurate and enduring part of the old.

Before we leave this part of the subject it may be noted that many persons have no idea of the kinds of information that may be obtained from books.

Even those who would unhesitatingly seek a book for data in history, art, or mathematics would not think of going to books for facts on plumbing, weaving, or shoe-making, for methods of shop-window decoration or of display-advertising, for special forms of bookkeeping suitable for factories or for stock-farms--for a host of facts relating to trades, occupations, and business in general. Yet there are books about all these things--not books perhaps to read for an idle hour, but books full of meat for them who want just this kind of food. If Book-taught Bilkins fails, after trying to utilize what such books have taught him, it is doubtless because he has previously failed to realize that books plus experience, or, to put it differently, the recorded experience of others plus our own is better than either could be separately. And the same is true of information that calls for no physical action to supplement it. Books plus thought--the thoughts of others plus our own--are more effective in combination than either could be by itself. Reading should provoke thought; thought should suggest more reading, and so on, until others'

thoughts and our own have become so completely amalgamated that they are our personal intellectual possessions.

But we may not read for information at all--recreation may be what we are after. Do not misunderstand me. Many persons have an idea that if one reads to amuse himself he must necessarily read novels. I think most highly of good novels. Narrative is a popular form of literary expression; it is used by those who wish to instruct as well as to amuse. One may obtain plenty of information from novels--often in a form nowhere else available. If we want exact statement, statistical or otherwise, we do not go to fiction for it; but if we wish to obtain what is often more important--accurate and lasting general impressions of history, society, or geography, the novel is often the only place where these may be had.

Likewise, one may amuse himself with history, travel, science, or art--even with mathematics. The last is rarely written primarily to amuse, although we have such a t.i.tle as "Mathematical recreations," but there are plenty of non-fiction books written for entertainment and one may read for entertainment any book whatever. The result depends not so much on the book or its contents as on the reader.

Recreation is now recognized as an essential part of education. And just as physical recreation consists largely in the same muscular movements that const.i.tute work, only in different combinations and with different ends in view, so mental recreation consists of intellectual exercise with a similar variation of combinations and aims.

Somebody says that "play is work that you don't have to do". So reading for amus.e.m.e.nt may closely resemble study--the only difference is that it is purely voluntary. Here again, however, the written language is only an intermediary; we have as before, the contact of two minds--only here it is often the lighter contact of good-fellowship. And one who reads always for such recreation is thus like the man who is always bandying trivialities, story-telling, and jesting--an excellent, even a necessary, way of pa.s.sing part of one's time, but a mistaken way of employing all of it.

The best kind of recreation is gently stimulating, but stimulation may rise easily to abnormality. There are fiction drunkards just as there are persons who take too much alcohol or too much coffee. In fact, if one is so much absorbed by the ideas that he is a.s.similating that the process interferes with the ordinary duties of life, he may be fairly sure that it is injuring him. If one loves coffee or alcohol, or even candy, so dearly that one can not give it up, it is time to stop using it altogether. If a reader is so fond of an exciting story that he can not lay it aside, so that he sits up late at night reading it, or if he can not drop it from his mind when he does lay it aside, but goes on thinking about the deadly combat between the hero and Lord William Fitz Grouchy when he ought to be studying his lessons or attending to his business, it is time to cut out fiction altogether. This advice has absolutely nothing to do with the quality of the fiction. It will not do simply to warn the habitual drunkard that he must be careful to take none but the best brands; he must drop alcohol altogether. If you are a fiction drunkard, enhanced quality will only enslave you further. This sort of use is no more recreation in the proper sense of the word than is gambling, or drinking to excess, or smoking opium.

And now we come to a use of books that is more important--lies more at the root of things--than their use for either information or recreation--their use for inspiration. One may get help and inspiration along with the other two--reading about how to make a box may inspire a boy to go out and make one himself. It is this kind of thing that should be the final outcome of every mental process. Nothing that goes on in the brain is really complete until it ends in a motor stimulus. The action, it is true, may not follow closely; it may be the result of years of mental adjustment; it may even take place in another body from the one where it originated. The man who tells us how to make a box, and tells it so fascinatingly that he sets all his readers to box-making, presumably has made boxes with his own hands, but there may be those who are fitted to inspire action in others rather than to undertake it themselves. And the larger literature of inspiration is not that which urges to specific deeds like box-making, or even to cla.s.ses of deeds, like caring for the sick or improving methods of transportation; rather does it include in its scope all good thoughts and all good actions. It makes better men and women of those who read it; it is revolutionary and evolutionary at the same time, in the best sense of both words.

What will thus inspire me, do you ask? It would be easy to try to tell you; it would also be easy to fail. Many have tried and failed. This is a deeply personal matter. I can not tell what book, or what pa.s.sage in a book, will touch the magic spring that shall make your life useful instead of useless, that shall start your thoughts and your deeds climbing up instead of grovelling or pa.s.sively waiting. Only search will reveal it.

The diamond-miner who expects to be directed to the precise spot where he will find a gem will never pick one up. Only he who seeks, finds. There are, however, places to look and places to avoid. The peculiar clay in which diamonds occur is well known to mineralogists. He who runs across it, looks for diamonds, though he may find none. But he who hunts for them on the rock-ribbed hills of New Hampshire or the sea-sands of Florida is doing a foolish thing--although even there he may conceivably pick up one that has been dropped by accident.
