V. MILWAUKEE, WISCONSIN. 



This is the second city in magnitude, population and commerce, on 

 Lake Michigan, being next to Chicago. It is also the largest city in 

 the State of Wisconsin. Its population is now near fifty thousand 

 (50,000) souls. It is very important that its position should be cor- 

 rectly laid down on the maps of our country. 



I was obliged to occupy three different stations in the course of the 

 observations made here, (or reasons which will be stated in turn. The 

 observations at each were reduc(>d to the position of the tall and con- 

 spicuous steeple of the Roman Catholic Church on Jackson street, 

 between Oneida and Riddle streets. This church is of permanent 

 structure, and was therefore selected as a monument for reference.
