The aim of this 1908 classic book is to present in, clear form, the simple principles of investment, and to afford the reader (listener!) knowledge of the various classes of securities that were available as investments at the time and their elative adaptability to different needs. The book is an outgrowth of the writer's personal experience as an investment banker. Most of the material appeared in the pages of System magazine, through the courtesy of whose editors it is now rearranged and consolidated in book form.
