"It is after you have mustered your industrial army into service," I said, "that I should expect the chief difficulty to arise, for there its analogy with a military army must cease. Soldiers have all the same thing, and a very simple thing, to do, namely, to practice the manual of arms, to march and stand guard. But the industrial army must learn and follow two or three hundred diverse trades and avocations. What administrative talent can be equal to determining wisely what trade or business every individual in a great nation shall pursue? "
"The administration has nothing to do with determining that point."
"Who does determine it, then?" I asked.
"Every man for himself in accordance with his natural aptitude, the utmost pains being taken to enable him to find out what his natural aptitude really is. The principle on which our industrial army is organized is that a man's natural endowments, mental and physical, determine what he can work at most profitably to the nation and most satisfactorily to himself. While the obligation of service in some form is not to be evaded, voluntary  election, subject only to necessary regulation, is depended on to determine the particular sort of service every man is to render. As an individual's satisfaction during his term of service depends on his having an occupation to his taste, parents and teachers watch from early years for indications of special aptitudes in children. A thorough study of the National industrial system, with the history and rudiments of all the great trades, is an essential part of our educational system. While manual training is not allowed to encroach on the general intellectual culture to which our schools are devoted, it is carried far enough to give our youth, in addition to their theoretical knowledge of the national industries, mechanical and agricultural, a certain familiarity with their tools and methods. Our schools are constantly visiting our workshops, and often are taken on long excursions to inspect particular industrial enterprises. In your day a man was not ashamed to be grossly ignorant of all trades except his own, but such ignorance would not be consistent with our idea of placing every one in a position to select intelligently the occupation for which he has most taste. Usually long before he is mustered into service a young man has found out the pursuit he wants to follow, has acquired a great deal of knowledge about it, and is waiting impatiently the time when he can enlist in its ranks."
"Surely," I said, "it can hardy be that the  number of volunteers for any trade is exactly the number needed in that trade. It must be generally either under or over the demand."
"The supply of volunteers is always expected to fully equal the demand," replied Dr. Leete. "It is the business of the administration to see that this is the case. The rate of volunteering for each trade is closely watched. If there be a noticeably greater excess of volunteers over men needed in any trade, it is inferred that the trade offers greater attractions than others. On the other hand, if the number of volunteers for a trade tends to drop below the demand, it is inferred that it is thought more arduous. It is the business of the administration to seek constantly to equalize the attractions of the trades, so far as the conditions of labor in them are concerned, so that all trades shall be equally attractive to persons having natural tastes for them. This is done by making the hours of labor in different trades to differ according to their arduousness. The lighter trades, prosecuted under the most agreeable circumstances, have in this way the longest hours, while an arduous trade, such as mining, has very short hours. There is no theory, no a priori rule, by which the respective attractiveness of industries is determined. The administration, in taking burdens off one class of workers and adding them to other classes, simply follows the fluctuations of opinion among the workers themselves as indicated by the  rate of volunteering. The principle is that no man's work ought to be, on the whole, harder for him than any other man's for him, the worker themselves to be the judges. There are no limits to the application of this rule. If any particular occupation is in itself so arduous or so oppressive that in order to induce volunteers, the day's work in it had to be reduced to ten minutes, it would be done. If, even then, no man was willing to do it. It would remain undone. But of course, in point of fact, a moderate reduction in the hours of labor, or addition of other privileges, suffices to secure all needed volunteers for any occupation necessary to men. If, indeed, the unavoidable difficulties and dangers of such a necessary pursuit were so great that no inducement of compensating advantages would overcome men's repugnance to it, the administration would only need to take it out on the common order of occupations by declaring it 'extra hazardous,' and those who pursued it especially worthy of the national gratitude, to be over run with volunteers. Our young men are very greedy of honor, and do not let slip such opportunities. Of course you will see that dependence on the purely voluntary choice of avocations involve the abolition in all of anything like unhygienic conditions or special peril to life and limb Health and safety are conditions common to all industries. The nation does not maim and slaughter its workmen by thousands, as did the private capitalists and corporations of your day." 
"When there are more who want to enter a particular trade than there is room for, how do you decide between the applicants?" I inquired.
"Preference is given to those who have acquired the most knowledge of the trade they wish to follow. No man, however, who through successive years remains persistent in his desire to show what he can do at any particular trade, is in the end denied an opportunity. Meanwhile, if a man cannot at first win entrance into the business he prefers, he has usually one or more alternative preferences, pursuits for which he has some degree of aptitude, although not the highest. Every one, indeed, is expected to study his aptitudes so as to have not only a first choice as to occupation, but a second or third, so that if either at the outset of his career or subsequently, owing to the progress of invention or changes in demand, he is unable to follow his first vocation, he can still find reasonably congenial employment. This principle of secondary choices as to occupation is quite important in our system. I should add, in reference to the counter-possibility of some sudden failure of volunteers in a particular trade, or some sudden necessity of an increased force, that the administration, while depending on the voluntary system for filling up the trades as a rule, holds always in reserve the power to call for special volunteers, or draft any force needed from any quarter. Generally, however, all needs of this sort can be met by  details from the class of unskilled or common laborers."
"How is this class of common laborers recruited?" I asked. "Surely nobody voluntarily enters that."
"It is the grade to which all new recruits belong for the first three years of their service. It is not till after this period, during which he is assignable to any work at the discretion of his superiors, that the young man is allowed to elect a special avocation. These three years of stringent discipline none are exempt from, and very glad our young men are to pass from this severe school into the comparative liberty of the trades. If a man were so stupid as to have no choice as to occupation, he would simply remain a common laborer; but such cases, as you may suppose, are not common."
"Having once elected and entered on a trade or occupation," I remarked, "I suppose he has to stick to it the rest of his life."
"Not necessarily," replied Dr. Leete; "while frequent and merely capricious changes of occupation are not encouraged or even permitted, every worker is allowed, of course, under certain regulations and in accordance with the exigencies of the service, to volunteer for another industry which he thinks would suit him better than his first choice. In this case his application is received just as if he were volunteering for the first time, and on the  same terms. Not only this, but a worker may likewise, under suitable regulations and not too frequently, obtain a transfer to an establishment of the same industry in another part of the country which for any reason he may prefer. Under your system a discontented man could indeed leave his work at will, but he left his means of support at the same time, and took his chances as to future livelihood. We find that the number of men who wish to abandon an accustomed occupation for a new one, and old friends and associations for strange ones is small. It is only the poorer sort of workmen who desire to change even as frequently as our regulations permit. Of course transfers or discharges, when health demands them, are always given."
"As an industrial system, I should think this might be extremely efficient," I said, "but I don't see that it makes any provision for the professional classes, the men who serve the nation with brains instead of hands. Of course you can't get along without the brain-workers. How, then, are they selected from those who are to serve as farmers and mechanics? That must require a very delicate sort of sifting process, I should say."
"So it does," replied Dr. Leete; "the most delicate possible test is needed here, and so we leave the question whether a man shall be a brain or hand worker entirely to him to settle. At the end of the term of three years as a common laborer,  which every man must serve, it is for him to choose, in accordance to his natural tastes, whether he will fit himself for an art or profession, or be a farmer or mechanic. If he feels that he can do better work with his brains than his muscles, he finds every facility provided for testing the reality of his supposed bent, of cultivating it, and if fit of pursuing it as his avocation. The schools of technology, of medicine, of art, of music, of histrionics, and of higher liberal learning are always open to aspirants without condition."
"Are not the schools flooded with young men whose only motive is to avoid work? "
Dr. Leete smiled a little grimly.
"No one is at all likely to enter the professional schools for the purpose of avoiding work, I assure you," he said. "They are intended for those with special aptitude for the branches they teach, and any one without it would find it easier to do double hours at his trade than try to keep up with the classes. Of course many honestly mistake their vocation, and, finding themselves unequal to the requirements of the schools, drop out and return to the industrial service; no discredit attaches to such persons, for the public policy is, to encourage all to develop suspected talents which only actual tests can prove the reality of. The professional and scientific schools of your day depended on the patronage of their pupils for support, and the practice appears to have been common of giving  diplomas to unfit persons, who afterwards found their way into the professions. Our schools are national institutions, and to have passed their test a proof of special abilities not to be questioned.
This opportunity for a professional training," the doctor continued, "remains open to every man till the age of thirty is reached, after which students are not received, as there would remain too brief a period before the age of discharge in which to serve the nation in their professions. In your day young men had to choose their professions very young, and therefore, in a large proportion of instances, wholly mistook their vocations. It is recognized nowadays that the natural aptitudes of some are later than those of others in developing, and therefore, while the choice of profession may be made as early as twenty-four, it remains open for six years longer."
A question which had a dozen times before been on my lips now found utterance, a question which touched upon what, in my time, had been regarded the most vital difficulty in the way of any final settlement of the industrial problem. "It is an extraordinary thing," I said, "that you should not yet have said a word about the method of adjusting wages. Since the nation is the sole employer, the government must fix the rate of wages and determine just how much everybody shall earn, from the doctors to the diggers. All I can say is,  that this plan would never have worked with us, and I don't see how it can now unless human nature has changed. In my day, nobody was satisfied with the wages or salary. Even if he felt he received enough, he was sure his neighbor had to much, which was as bad. If the universal discontent on this subject, instead of being dissipated in curses and strikes directed against innumerable employers, could have been concentrated upon one, and that the government, the strongest ever devised would not have seen two pay days."
Dr. Leete laughed heartily.
"Very true, very true," he said, "a general strike would most probably have followed the first pay day, and a strike directed against a government is a revolution."
"How, then, do you avoid a revolution every pay day" I demanded. "Has some prodigious philosopher devised a new system of calculus satisfactory to all for determining the exact and comparative value of all sorts of service, whether by bran or brain, by hand or voice, by ear or eye? Or has human nature itself changed, so that no man looks upon his own things but 'every man on the things of his neighbor.' One or the other of these events must be the explanation."
"Neither one nor the other, however, is," was my host's laughing response. "And now, Mr. West," he continued, "you must remember that you are my patient as well as my guest, and permit  me to prescribe sleep for you before we have any more conversation. It is after three o'clock."
"The prescription is, no doubt, a wise one," I said; "I only hope it can be filled."
"I will see to that," the doctor replied, and he did, for he gave me a wineglass of something or other which sent me to sleep as soon as my head touched the pillow.
