TWENTY-EIGHT MILLIONS OF 



DOLLARS and over is the value given 

 by the Collector of Customs for the 

 commerce of the Portof 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 end of Lake Su- 

 perior. Its population has more than 

 doubled in 1889. Joaquin Miller be- 

 lieves it is destined to outstrip 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 Superior and vicinity will be- 

 gladly given by
