 changed for other things. Other things 

 fluctuated in value according to their de-

 changeability fell greatly where there was 

 overproduction of goods, and it would be 

 futile and unjust to take the values of 

 goods, even over an average of time, as a 

 proper measure of values. Gold money 

 was the touch-stone of the need for goods. 

 If they rose in price in gold it was an indi-

 in gold it was an indication of overpro-
