BONDS AND STOCKS 
(1) Purchase the stocks of producing, and if 
possible, dividend-paying mines. 
(2) Divide the investment equally among the 
mines of the above mentioned groups. 
(3) Insist upon a yield which will provide for 
laying aside each year a proper proportion of the 
dividends for a sinking fund, or else purchase the 
stocks only of companies which, of themselves, set 
aside a proper proportion of their earnings for the 
acquirement of additional property. 
(4) Purchase stocks when the price of copper 
is at or near its lowest point. Of course, to decide 
this latter question one should be thoroughly famil 
iar with business conditions and much more of a 
student than is the ordinary investor. The an 
nexed chart clearly shows both the price and pro 
duction of copper during the last thirty-five years, 
and when studied in connection with the price of 
iron and other commodities, it will be found very 
helpful.
