In accordance with the scope of the series of Books on Business, of which this little work forms an item, its main object is to explain to the unversed in simple terms the somewhat complicated machinery of the Stock Exchange. Some criticism is ventured upon here and there, and a practical hint may be gleaned now and again from its pages; but the real aim of the book is merely to explain, not to comment. If the book conveys some idea of the important part the Stock Exchange plays in the economy of the nation, and of how it plays that part; if it furnishes a solution of the various mysteries which the routine of the Stock Exchange presents to many minds, the objects of the little work will have been attained.
