PHYSICAL AND GEOLOGICAL DESCRIPTION, 



veyed, was straight from the bridge over Island Creek at 

 Cape Island to Dennisville ; there it curved slightly to the 

 left, and then continued, on another straight course, to the 

 western border of the county, which it crossed near Hoff- 

 man's Mill. In the table, the first column gives the miles 

 from Cape Island ; the second gives the average elevation 

 in feet, of each mile above high tide ; the third gives the 

 highest ground passed over in each mile; and the fourth 

 gives the lowest. 



§ This ejxtreme uniformity of surface is a great hindrance 

 to the study of the geological structure of the county. 

 The slight elevations, which are met with, are generally in
