2. I beg leave to correct a misleading passage in a footnote to p. 79 of _The Economic Consequences of the Peace_. I there spoke of “Poland’s pre–war annual demand” for coal, where I should have said “pre–war Poland’s pre–war annual demand.” The mistake was not material, as I allowed for Germany’s diminished requirements for coal, due to loss of territory, in the body of the text. But I confess that the footnote, as published, might be deemed misleading. At the same time it is, I think, a tribute to the general accuracy of _The Economic Consequences_ that partizan critics should have fastened so greedily on the omission of the word “pre–war” before the word “Poland” in the footnote in question. Quite a considerable literature has grown up round it. The Polish Diet devoted January 20, 1921, to the discussion and patriotic analysis of this footnote, and concluded with a Resolution ordering the chief speech of the occasion (that of Deputy A. Wierzlicki) to be published throughout the world in several languages at the expense of the State. I apologize for any depreciation in the Polish mark for which I may have been so inadvertently responsible. Mr. Wierzlicki begins: “A book appeared by Keynes ... the author of a well–known work on India, that pearl of the English crown, that land which is a beloved subject of study to the English. Through such studies a man may win himself name and fame,”—which was certainly a little unscrupulous of me. And he concludes: “But England too must believe in facts! And if Keynes, whose book is impregnated with a humanitarian spirit and with understanding of the necessity to get up beyond selfish interests, if Keynes is convinced by actual data that he has done a wrong, that he has wrought confusion in the ideas of statesmen and politicians as regards Upper Silesia, then he too will see with his eyes and must become the friend of Poland, of Poland as an active factor in the development of the natural wealth of Silesia.” I owe it to so generous and eloquent a critic to quote the corrected figures, which are as follows: the Polish lands, united by the Peace Treaty into the new Polish State, consumed in 1913 19,445,000 tons of coal, of which 8,989,000 tons were produced within that area and 7,370,000 tons were imported from Upper Silesia (the total production of Upper Silesia in that year being 43,800,000 tons).[26] The Silesian Plebiscite has been preceded and followed by a mass of propagandist literature on both sides. For the economic questions involved see, particularly, on the Polish side: Wierzlicki, _The Truth about Upper Silesia_; Olszewski, _Upper Silesia, Her Influence on the Solvability and on the Economic Life of Germany_, and _The Economic Value of Upper Silesia for Poland and Germany respectively_; and on the German side: Sidney Osborne, _The Upper Silesian Question and Germany’s Coal Problem, The Problem of Upper Silesia_ (papers by various authors, not all on the German side,
