[113] The best short summaries of the pre-war wage situation are--"The Standard of Living among the Industrial People of America" (1911), by F. H. Streightoff, and an article by C. E. Persons in the February, 1915, issue of _The Quarterly Journal of Economics_. For a more extensive study see the Report of the Commission of Enquiry of the Board of Trade (Great Britain) into working class rents, etc., which contains material of great value. A recent comprehensive survey of wages in the United States, undertaken by the Bureau of Labor Statistics for the War Industries Board was published in May, 1920. It is Bulletin No. 265, U. S. Bureau of Labor Statistics, "Industrial Survey in Selected Industries in the United States, 1919." [114] South Australian Ind. Reports. Vol. 2-3--1919. Page 6--Submission by Employees in Cardboard Box Industry. Quoted from Printing Trades Case. [115] _Labor Gazette of the Dominion of Canada_, August, 1918, page 617. [116] As reported in the _Survey_, April 6, 1918. [117] Second Annual Report of the Minimum Wage Board, District of Columbia (1919), page 18. [118] An excellent study of the technique of measurement of the cost of living is that by W. F. Ogburn, "Measurement of the Cost of Living and Wages." No. 170, _Annals of the American Academy of Political and Social Science_ (1919). The article helps to put much firm ground under the feet of those engaged in cost of living investigations for the United States. For a description of the methods pursued in official cost of living investigations in Great Britain, see the account by F. H. McLeod in the June, 1919, issue of the _U. S. Monthly Labor Bulletin_, page 119. [119] The Plumber's Case, South Australian Industrial Reports (Volume I, 1916-18), page 122.
