The gratifying promptitude with which the reading public has called for a second edition of this book is a striking testimony to the interest that is now being taken in the International Money Market of the world. How great is that interest is revealed by the numerous letters that have reached the Author from kindly correspondents who have asked that more prominence be given to the inner working of our great monetary machine. Effect has been given to their wishes wherever possible. Further facts in regard to the Discount Market and the bills that one finds therein have been added, and, in order to make the Government’s connection with the market clearer, the opportunity has been taken to incorporate additional material in regard to the effect of the circulation and issue of Currency Notes and Treasury Bills.
