[3] A. Marshall, Appendix N, "Industry and Trade," entitled "The Recent Increase in the Size of the Representative Business Establishment in the United States," has drawn up some tables on this very subject. He writes, "The table given below shows that the 208,000 establishments engaged in manufacture in 1900 had increased to 268,000; but meanwhile the total value of their output had increased from $4,831 M to $8,529 M: that is, their average output had increased from 232,000 to 318,000: if we go back to 1850, when workshops, etc., were reckoned in, we find the average output of an establishment to have been less than 4,000 dollars." And again "Industrial establishments having a less output than 100,000 dollars accounted for 20.7 per cent. of the whole in 1904; but only 17.8 in 1909. In the same years the share of establishments with output between 100,000 dollars and 1,000,000 dollars fell from 46.0 to 43.8, while that of grant businesses with not less than 1,000,000 dollars output rose from 38 per cent. to 43."

Commission," Vol. IX. [6] A. Marshall, "Principles of Economics" (7th edition), page 206. [7] In an analysis of the trend toward union amalgamation published by Glocker in 1915, he concludes that "Instances in which the self interest of the skilled workers demand their amalgamation with the unskilled are still rare, however. If common laborers are admitted in the near future to unions of other workers in the same industry, they will be admitted not from self interest, but from more altruistic motives, from a growing spirit of class consciousness attended, perhaps, by a correspondingly growing realization of class responsibility"--"Amalgamation of Related Trades in Unions." _American Economic Review_, Sept., 1915, page 575. [8] Under the Kansas Industrial Court Law passed in 1920, no provision in that direction is made. The Court is instructed to deal either with organizations or with individuals. It is likely that the Court, in its efforts to get disputes settled before they reach it, will find it necessary to encourage organization. A related question which is bound to arise sooner or later is in regard to the stand that the court will take in disputes arising out of attempts to organize an industry.
