[From the Proceedings of the American Association for the advancement of Science, Vol. XXXIV, Ann Arbor Meeting, August, 1885.] The science of statistical analysis. By Charles S. Hill, State Department, Washington, D. C. The Sciences are becoming, as they should be, the feature of education. Not that the classics must go, but that the sciences must come ; between these two classes in our colleges, and in our social and public relations, there is at present an evidence of feeling akin more to bitterness than to reason. The classic scholar has for so long a period ignored the greater importance and classification of scientific branches of knowledge that the modesty of the student, seeking skilfully the develop- ment of practical industry at home, and commercial relations with foreign countries, has unjustly and injuriously kept back much benefit to the masses of mankind and rational principles of reason. The beautiful accomplishment of a proficiency in interchanging thought and salutation in a common language gives grace, ease, and elegance to intercourse in society, in travelling, in diplomacy, and in many associations, as well as in study, but it is likewise a burden if allowed to obstruct the progress of industry. It is in the education of the masses that the power of a nation lies ; that the light of knowledge burns brightest and incessantly for the benefit of mankind. And even in the gradual advance of science to the foremost rank of study there has been too much disposition to disregard the many distinctive branches, and particularly the very rudiments of this standard of knowledge, even as the classic scholar has dis- 509 510 SECTION I. regarded the multiplicity, and often the most important base, of languages. Content with the acquirement of a science, the student often glo- ries in the knowledge of a principle without according his knowl- edge to the scientific system of research through the labyrinths of natural matter and analysis of statistical data by means of which knowledge is attained, and in many instances, it must be said with regret, without a willingness even to acknowledge that the system of analysis is a distinct and most important science-much less the rudiment of all sciences I The science of statistical analysis is paramount in the importance of correctness of result and satisfactory comprehension of how that result can be verified. The analysis of official statistical data is mining in mountains of precious metals - a miner's labor in separating the gold from the sulphurets. The labor of such work is purely and indisputably a science of the highest order. To separate and group together the figures and facts of greatest value, exhibiting and analyzing the wealth of hid- den knowledge, and interweaving chains of social problems with golden truths-otherwise left buried from view-which glisten the brighter when contrasted with the brassy alloys of sophistry or the counterfeit representations of fallacy, is a science without a peer. The definition of science, says Professor Fowler, of Oxford, " is the filiation of causes through the common observation to things beyond." Accepting the expression of Professor Fowler, we must accept, as the corner-stone of all sciences, arithmetic, the only basis upon which we may, with that second stone of science, logic, found an article on political economy, which, as a knowledge, is far more powerful in influence, effective in application, and brilliant as well as bountiful in results. To be thus effectual and bountiful in results, delicate distinction between like and unlike conditions is essential; similia similibus curantur is a faithful precept; but the application of like doctrine to cure evil or to guide our course merely upon general principles is the most fatal error into which a people may fall especially in economics. While the first object of the student is to find the origin of his subject, his great error, like that of some " professors " of theo- ECONOMIC SCIENCE AND STATISTICS. 511 retical economy, is in applying the derivations of terms to their rea- soning rather than in pursuing the pure science of defining the cause that must work the results. But neither science, arithmetic nor logic, can produce food or the other necessaries of life ; it requires good sense and reason which practical experience alone can give, to apply rules or prin- ciples to trading and economy. To draw these thoroughly into harmonious unity of action in our individual daily life is not only advisable, but essential to our prosperity, and, therefore, we must look particularly into the causes which create results rather than into the etymology of words or rules of syntax, and not forget to reason upon science with " Good sense, which is alone the gift of Heaven, And-though no science-fairly worth the seven." Statistical science, applied to social phenomena, enables us to comprehend facts which to the unthinking are incredible. One fact is worth one hundred theories. No greater misnomer can be applied to him who " has no time " for such data than the word " practical. " Nor should it be considered that the logic of statistics belongs alone to scientists. It is an essential in the education of every man who desires to arrange his study or regulate his own business cor- rectly. It is as important to possess this safeguard or guide through the numerous channels of occupation in life as the chart is to guide the mariner through the entrance to his harbor. How necessary, then, is the systematic preparation of official statistical data from all parts of the world, and how much more necessary that the analysis of such data should be made and is- sued authoritatively, that our manufacturers, merchants, and, in- deed, our whole people, may be assured that the information they receive is not deceiving. For more than a hundred years the Government of the United States failed to appreciate fully the Consul as a factor in the great work of protecting and enlarging the foreign commerce of the country. And yet the principal idea held by the founders of our Republic, when creating the consular service, was the development of inter- national trade through the medium of agents of the United States 512 SECTION I, throughout the world to protect and enlarge our commercial re- lations. Such intent is evinced in all our state papers, although at times this idea seems to have been disregarded or lost sight of. The first effort to give system by organization to the promul- gation of the valuable information acquired by these representa- tives for the benefit of our industries, as well as for the extension of our commerce, under the preparation and direction of the United States Department of State, was by the Act of Congress, August 16, 1842, followed by Act of August 18, 1856, and of July 4, 1864. A further act of Congress, June 20, 1874, created the office of Chief of the Bureau of Statistics in the Department of State for the development of such work. This act was never annulled, although rendered inoperative by failure from indifference to provide means for the proper working of the same. That bureau, however, increased by provision of an Act of Con- gress, June 16, 1880, granting a very small force, and ordering more frequent publication of its results. A further Act of Congress, March 3, 1881, renewed the last ap- propriation with a small but inadequate increase for the monthly issue of such information as had proved so acceptable to the public. These publications by the Department of State, during the last four years, have been analyses of " The State of Labor in Europe ; " " The Commerce of the World," and "The Share of the United States Therein" The Cotton Goods Trade of the World " Glass," " Cereals," Ostrich," " Petroleum," and " Fruit Industries," and " The Credit System of the World," "The Con- dition of Labor Abroad,"-compared with conditions at home,- in connection with the regular monthly series, which have clearly demonstrated the possibility of the usefulness of the consul, if properly encouraged and conserved in his true sphere. The Consul's reports, which convey so much useful data, were formerly, necessarily, doomed to oblivion in the archives of unpub- lished and unread history, if we except those very few which ap- peared in the annual volume after lapse of time and without ex- amination, analysis, or deduction, and which consequently served no higher usefulness than very unreliable works of reference, par- ECONOMIC SCIENCE AND STATISTICS. 513 ticularly from their old date, and from the natural absence of incentive to the consul, especially in the practical utility of his work or appreciation by the public, which always stimulates pride and correctness. In the spring of 1880 the Department of State made strenuous efforts to remedy this evil and utilize this vast field of information by more frequent and immediate publication of special and se- lected reports, as referred to above, relating to every industry and every condition of other nations, whereby our own social and in- dustrial conditions might be advanced. To accomplish this work was at first a great difficulty, but finally, through earnest efforts and determination, the exhumation of the consul from obscurity to conspicuousness-his revival from inaction to usefulness-was effected through this channel of com- munication that enables him to show himself publicly according to his real merit, and serve his country practically. Thus for about four years this system has been tried in a very small way. In this short time that department has daily received letters from scientists of all branches, from senators and members of Congress, from industrial, educational, and other corporate bodies, from private individuals, home and foreign, attesting the value of these publications, and requesting that more copies, if possible, be supplied ; which request, however, has been only partially complied with out of the limited issue of 10,000 copies, 4,000 of which are supplied to Congress, and about 2,000 to consuls, an average of 10 each to the former and 3 each to the latter ; the remainder being demanded by the press, merchants, and laboring masses. When it is taken into consideration that every report, previous to publication, has to be copied, revised, condensed, often corrected, and sometimes rewritten, the labor incident thereto can be appre- ciated, and not even then to its full extent, save by men who have experience in the work of statistical analyses. The scope of the field of information, as set forth in the require- ments of consular regulations, 1881, article 27, paragraph 556, em- braces the following industries, viz.: 1. Agriculture. 2. Manufactures. 3. Mining. 514 SECTION I 4. Fisheries. 5. Forestry. 6. Commerce and Navigation. 7. Revenues. 8. Miscellaneous, covering the conditions and peculiarities in business and habits of the several peoples of the world, viz., pop- ulation, emigration, labor, wages, prices of food and living. The last three Secretaries of State, Messrs. Evarts, Blaine and Frelinghuysen, under whose supervision and direction this labor has been performed, have fully appreciated these difficulties and have repeatedly called Congressional attention to the same and asked for sufficient provisions to enable that department to carry out this new system to its most profitable extent and in order to meet the petitions of the commercial community, made to the department, in this endeavor. It is hardly possible to day to meet and converse with a bus- iness or literary man from or in any city of our country who will not in some way speak of the benefit or pleasure he has derived from this systematic preparation and publication of official mat- ter and data. Contrast the benefit of the system of education and scientific analysis with the circumscribed condition and narrow- mindedness of the classic Turkish Cadi, Imaum Ali Zade, in reply to, and as given to the public by Mr. Layard, regarding the indus- try and commerce of Constantinople : " The thing you ask of me is both difficult and useless. Although I have passed all my days in this place, I have neither counted the houses, nor have I inquired into the number of inhabitants; and as to what one person loads on his mules, and another stows away in the bottom of his ship, that is no business of mine. But, above alb as to the previous of this city, God only knows the amount of dirt and confusion that the in- fidels may have eaten before the corning of the sword of Islam. It were unprofitable for us to inquire into it. O my soul! O my lamb! seek not after the things which concern thee not. Thou earnest unto us and we welcomed thee : go in peace." Such contractedness of mind and illiberality are too apt to pre- vail even with a few nearer our own home, but as " the sciences must come," so will analysis of the several sciences from rudiment to maturity, and their results be properly and justly classified. ECONOMIC SCIENCE AND STATISTICS. 515 The science of statistics may be credited to Sir Wm. Petty, of England, as its founder about the year 1650, but was first system- ized by Gottfried Achenwall, of Germany, a century later, who gave the name of Staat to his labor of love, and his noble pur- poses have been matured and wonderfully advanced by Quetelet, of Belgium ; Engel, of Dresden ; Rouher, of France; Bodio, of Italy; Neumann Spellart, of Austria ; Giffin, Bourne, and Levi; Farr, of England ; and their names will soon be " legion," and the world will be all the wiser for the work of those Statists, indeed! " And lovers of their country," Germany and England were the primogenitors of this science, the great value of which is now being appreciated by the civilized world. Nothing could be more forcible, more beautiful, or more appropriate here than the words of the Prince Consort Albert in opening the statistical Congress in London in 1860 : "Happy and proud indeed should I feel if this noble gathering should be enabled to lay the solid foundations of an edifice, necessarily slow of con- struction, and requiring for generations to come laborious and persevering exertions, intended as it is for the promotion of human happiness by lead- ing to the discovery of those eternal laws upon which universal happiness is dependent." These noble words are republican in sentiment, although born of a royal mind. Is not, then, statistical analysis the foundation of every science, the development of all good, the exposition of all bad ? and may we not hope for the sake of truth and practical usefulness and com- mon sense, rather than theoretical sophistry, that this science may in our colleges and universities be particularly " Tutored in the rudiments Of many desperate studies"?
