TOPOGRAPHY OF THE SECTION. 
In the following table the distances between stations as cal- 
culated from the cyclometer readings are given. The eleva- 
tions given are calculated from the aneroid readings and cor- 
rected by the barograph readings. The resulting elevations 
are of the various stations above the mean level of lake Huron, 
which is taken as 580 feet above the sea.
