their number and distribution. These are matters of considerable interest, in con- 

 sequence of the influence which the presence of so great an assemblage of waters 

 must exercise on the climate and productions of the region in which they are 

 situated. 



The general level of the country, between Lake Superior and the Mississippi, is 

 shown in the profile of the same, the former being taken as a base. These lines 

 of level must be received as approximations only, as, in many instances, time 

 would only allow of one or two barometrical observations being made, for the pur- 

 pose of ascertaining heights. At most important points, however, the mean of 

 from five to twenty observations was used in making the calculations ; and in 

 every calculation the mean of one month's observations, at a single station on 

 Lake Superior, was employed. The following table exhibits the elevations, as 

 determined along some of the lines of observation : —
