INVESTORS 



should appreciate the fact that the new 

 trans-continental systems of Railway 

 and Lake transport ition are making 

 the City of Superior, Wisconsin, their 

 focal point and will rapidly develop 

 that city into a successful bidder for 

 trade now controlled by Chicago. 



Superior, Wisconsin, is the farthest 

 inland of any Ameiican City accessible 

 by water and is neaier than Chicago by 

 rail, to Omaha, St. Paul, Minneapolis 

 and ail poincs Nortih and West of those 

 cities. It is in the heart of the richest 

 iron and lumber rej^ions in the United 

 States; has grown from 7,000 to 14,000 

 population during the past year ; in- 

 creased its lake commerce from $9,- 

 836,461 in 1888 to $38,053,730 in 1889. 

 It is going ahead now more rapidly 

 than ever before. Shrewd investors 

 will recognize the importance of these 

 facts and act uj)on them. 



I invest money in Eeal Estate or 

 First Mortgage Loans, and guarantee 

 Ifo profits. Write me for information. 

 Inquiry will cost you nothing. I refer 

 by permission to Editor of Scien"CE, 

 and will furnish other references ou 

 application. Address
