work, the complicated ingenuity, the money and the personnel that were required. Nothing like that exists in time of peace, and as a corollary there are whole sections, there are vast groups, ghettoes, enclaves and classes that hear only vaguely about much that is going on.

They live in grooves, are shut in among their own affairs, barred out of larger affairs, meet few people not of their own sort, read little. Travel and trade, the mails, the wires, and radio, railroads, highways, ships, motor cars, and in the coming generation aeroplanes, are, of course, of the utmost influence on the circulation of ideas. Each of these affects the supply and the quality of information and opinion in a most intricate way. Each is itself affected by technical, by economic, by political conditions. Every time a government relaxes the passport ceremonies or the customs inspection, every time a new railway or a new port is opened, a new shipping line established, every time rates go up or down, the mails move faster or more slowly, the cables are uncensored and made less expensive, highways built, or widened, or improved, the circulation of ideas is influenced. Tariff schedules and subsidies affect the direction of commercial enterprise, and therefore the nature of human contracts. And so it may well happen, as it did for example in the case of Salem, Massachusetts, that a change in the art of shipbuilding will reduce a whole city from a center where international influences converge to a genteel provincial town. All the immediate effects of more rapid transit are not necessarily good. It would be difficult

to say, for example, that the railroad system of France, so highly centralized upon Paris, has been an unmixed blessing to the French people.

It is certainly true that problems arising out of the means of communication are of the utmost im-' portance, and one of the most constructive features of the program of the League of Nations has been the study given to railroad transit and access to the sea. The monopolizing of cables,1 of ports, fuel stations, mountain passes, canals, straits, river courses, terminals, market places means a good deal more than the enrichment of a group of business men, or the prestige of a government. It means a barrier upon the exchange of news and opinion. But monopoly is not the only barrier. Cost and available supply are even greater ones, for if the cost of travelling or trading is prohibitive, if the demand for facilities exceeds the supply, the barriers exist even without monopoly.

The size of a man's income has considerable effect on his access to the world beyond his neighborhood. With money he can overcome almost every tangible obstacle of communication, he can travel, buy books and periodicals, and bring within the range of his attention almost any known fact of the world. The income of the individual, and the income of the community determine the amount of communication that is possible. But men's ideas determine how that income shall be spent, and that in turn affects in the long run the amount of income they will have. Thus

also there are limitations, none the less real, because they are often self-imposed and self-indulgent.

There are portions of the sovereign people who spend most of their spare time and spare money on motoring and comparing motor cars, on bridgewhist and post-mortems, on moving-pictures and potboilers, talking always to the same people with minute variations on the same old themes. They cannot really be said to suffer from censorship, or secrecy, the high cost or the difficulty of communication. They suffer from anemia, from lack of appetite and curiosity for the human scene. Theirs is no problem of access to the world outside. Worlds of interest are waiting for them to explore, and they do not enter.

They move, as if on a leash, within a fixed radius of acquaintances according to the law and the gospel of their social set. Among men the circle of talk in business and at the club and in the smoking car is wider than the set to which they belong. Among women the social set and the circle of talk are frequently almost identical. It is in the social set that ideas derived from reading and lectures and from the circle of talk converge, are sorted out, accepted, rejected, judged and sanctioned. There it is finally decided in each phase of a discussion which authorities and which sources of information are admissible, and which not.

Our social set consists of those who figure as people in the phrase "people are saying"; they are the people whose approval matters most intimately to us. In big cities among men and women of wide

interests and with the means for moving about, the social set is not so rigidly defined. But even in big cities, there are quarters and nests of villages containing self-sufficing social sets. In smaller communities there may exist a freer circulation, a more genuine fellowship from after breakfast to before dinner. But few people do not know, nevertheless, which set they really belong to, and which not.

Usually the distinguishing mark of a social set is the presumption that the children may intermarry. To marry outside the set involves, at the very least, a moment of doubt before the engagement can be approved. Each social set has a fairly clear picture of its relative position in the hierarchy of social sets. Between sets at the same level, association is easy, individuals are quickly accepted, hospitality is normal and unembarrassed. But in contact between sets that are "higher" or "lower," there is always reciprocal hesitation, a faint malaise, and a consciousness of difference. To be sure in a society like that of the United States, individuals move somewhat freely out of one set into another, especially where there is no racial barrier and where economic position changes so rapidly.

Economic position, however, is not measured by the amount of income. For in the first generation, at least, it is not income that determines social standing, but the character of a man's work, and it may take a generation or two before this fades out of the family tradition. Thus banking, law, medicine, public utilities, newspapers, the church, large retailing, brokerage, manufacture, are rated at a different

but it does

social value from salesmanship, superintendence, expert technical work, nursing, school teaching, shop keeping; and those, in turn, are rated as differently from plumbing, being a chauffeur, dressmaking, subcontracting, or stenography, as these are from being a butler, lady's maid, a moving picture operator, or a locomotive engineer. And yet the financial return | does not necessarily coincide with these gradations.

Whatever the tests of admission, the social set when formed is not a mere economic class, but something which more nearly resembles a biological clan. Membership is intimately connected with love, marriage and children, or, to speak more exactly, with the attitudes and desires that are involved. In the social set, therefore, opinions encounter the canons of Family Tradition, Respectability, Propriety, Dignity, Taste and Form, which make up the social set's picture of itself, a picture assiduously implanted in the children. In this picture a large space is tacitly given to an authorized version of what each set is called upon inwardly to accept as the social standing of the others. The more vulgar press for an outward expression of the deference due, the others are decently and sensitively silent about their own knowledge that such deference invisibly exists. But that knowledge, becoming overt when there is a marriage, a war, or a social upheaval, is the nexus of a large bundle of dispositions classified by Trotter 1 under the general term instinct of the herd.
