TWENTY-EIGHT MILLIONS OF 



DOLLARS and over is the value given 

 the Collector of Customs for the com- 

 merce of the Port of Superior, Wis., 

 for 1889. In 1888 the valuation was 

 less than ten millions of dollars. 



WEST SUPERIOR, Wis., 



is a four-year-old city of 10,000 people, 

 at the extreme west eud of Lake Su- 

 perior. Its population has more than 

 doubled in 1889. Joaquin Miller be- 

 lieves it is destined to outstri]] Chicago 

 in growth, and will rank with New 

 York as a commercial, financial and 

 manufacturing center. It is worth in- 

 vestigation if half of this is so; for in- 

 vestors in real estate and mortgage 

 loans can realize large profits in such 

 growing towns. Information regard- 

 ing West Sui^erior and vicinity will be 

 gladly given by
