FORECASTING A BULL MARKET—1908-1909. NATURE AND USES OF SECONDARY SWINGS. 1909, AND SOME DEFECTS OF HISTORY. A "LINE" AND AN EXAMPLE—1914.. XVI. AN EXCEPTION TO PROVE THE RULE.. XVII. ITS GREATEST VINDICATION-1917 60 ..... PREFACE A preface is too often an apology, or at best an explanation of what should be sufficiently clear. This book requires no apology, and if it fails to explain itself the fault is that of the author. But acknowledgment must be made most gratefully to Clarence W. Barron, president of Dow, Jones & Co., and to Joseph Cashman, manager of that great financial news service, for permission to use the indispensable Dow-Jones stock-price averages, and to my old comrade in Wall Street newspaper work, Charles F. Renken, compiler of those averages, for the charts here used in illustration. W. P. H. |
