A GYPSY FORTUNE-TELLER: SAX LUIS POTOSI, MEXICO 



San Luis Potosi is another of those Mexican cities with a population of more than 60,000 

 which causes the traveler to wonder how it manages to exist. The country around is so dry 

 and parched that it would seem that it could not even partially provision a city of such size. 

 But silver is the key to the secret. Mexican history shows that cities always grow close to 

 silver mines, and that inhospitality of soil cannot counteract the magnetism of silver.
