knew all the mysteries of their craft. Then the mysteries grew more mysterious, and at last industry began to depend upon physical laws and chemical combinations that no eye could see, and only a trained mind could conceive. The scientist moved from his noble garret in the Latin Quarter into office buildings and laboratories. For he alone could construct a working image of the reality on which industry rested. From the new relationship he took as much as he gave, perhaps more: pure science developed faster than applied, though it drew its economic support, a great deal of its inspiration, and even more of its relevancy, from constant contact with practical decision. But physical science still labored under the enormous limitation that the men who made decisions had only their commonsense to guide them. They administered without scientific aid a world complicated by scientists. Again they had to deal with facts they could not apprehend, and as once they had to call in engineers, they now have to call in statisticians, accountants, experts of all sorts.

These practical students are the true pioneers of a new social science. They are "in mesh with the driving wheels" and from this practical engagement of science and action, both will benefit radically: action by the clarification of its beliefs; beliefs by a continuing test in action. We are in the earliest beginnings. But if it is conceded that all large forms of human association must, because of

sheer practical difficulty, contain men who will come to see the need for an expert reporting of their particular environment, then the imagination has a premise on which to work. In the exchange of technic and result among expert staffs, one can see, I think, the beginning of experimental method in social science. When each school district and budget, and health department, and factory, and tariff schedule, is the material of knowledge for every other, the number of comparable experiences begins to approach the dimensions of genuine experiment. In forty-eight states, and 2400 cities, and 277,000 school houses, 270,000 manufacturing establishments, 27,000 mines and quarries, there is a wealth of experience, if only it were recorded and available. And there is, too, opportunity for trial and error at such slight risk that any reasonable hypothesis might be given a fair test without shaking the foundations of society.

The wedge has been driven, not only by some directors of industry and some statesmen who had to have help, but by the bureaus of municipal research,1 the legislative reference libraries, the specialized lobbies of corporations and trade unions and public causes, and by voluntary organizations like the League of Women Voters, the Consumers' League, the Manufacturers' Associations: by hun

Upson of the Detroit Bureau of Governmental Research, Miss Rebecca B. Rankin of the Municipal Reference Library of New York City, Mr. Edward A.

dreds of trade associations, and citizens' unions; by publications like the Searchlight on Congress and the Survey; and by foundations like the General Education Board. Not all by any means are disinterested. That is not the point. All of them do begin to demonstrate the need for interposing some form of expertness between the private citizen and the vast environment in which he is entangled.

CHAPTER XXVI

INTELLIGENCE WORK

I

THE practice of democracy has been ahead of its theory. For the theory holds that the adult electors taken together make decisions out of a will that is in them. But just as there grew up governing hierarchies which were invisible in theory, so there has been a large amount of constructive adaptation, also unaccounted for in the image of democracy. Ways have been found to represent many interests and functions that are normally out of sight.

We are most conscious of this in our theory of the courts, when we explain their legislative powers and their vetoes on the theory that there are interests to be guarded which might be forgotten by the elected officials. But the Census Bureau, when it counts, classifies, and correlates people, things, and changes, is also speaking for unseen factors in the environment. The Geological Survey makes mineral resources evident, the Department of Agriculture represents in the councils of the nation factors of which each farmer sees only an infinitesimal part: School authorities, the Tariff Commission, the consular service, the Bureau of Internal Revenue give representation to persons, ideas, and objects which would never automatically find them

selves represented in this perspective by an election. The Children's Bureau is the spokesman of a whole complex of interests and functions not ordinarily visible to the voter, and, therefore, incapable of becoming spontaneously a part of his public opinions. Thus the printing of comparative statistics of infant mortality is often followed by a reduction of the death rate of babies. Municipal officials and voters did not have, before publication, a place in their picture of the environment for those babies. The statistics made them visible, as visible as if the babies had elected an alderman to air their grievances.

In the State Department the government maintains a Division of Far Eastern Affairs. What is it for? The Japanese and the Chinese Governments both maintain ambassadors in Washington. Are they not qualified to speak for the Far East? They are its representatives. Yet nobody would argue that the American Government could learn all that it needed to know about the Far East by consulting these ambassadors. Supposing them to be as candid as they know how to be, they are still limited channels of information. Therefore, to supplement them we maintain embassies in Tokio and Peking, and consular agents at many points. Also, I assume, some secret agents. These people are supposed to send reports which pass through the Division of Far Eastern Affairs to the Secretary of State. Now what does the Secretary expect of the Division? I know one who expected it to spend its appropriation. But there are Secretaries to
