 their labor by an appeal to the fossils. 



Me. Edgeeton's Suevey. — Mr. B. H. Edgerton, engineer, having 

 been commissioned by the Milwaukee and Northern -Railroad Com- 

 pany to survey the northern extension of their road from Green Bay, 

 an arrangement was made with him to report the results of such ob- 

 servations as he might be able to make, that would forward the ob- 

 jects of the geological survey. The line run was from near Green 

 Bay, in ranges 19 and 20, very directly north to the Menomonee river, 

 which it crossed at the head of the Big Quinnesec Falls. The list of 

 elevations furnished by him shows the height of the ground above 

 the level of Lake Michigan at the crossing of every section line, and 

 the level of the surface of the water in the rivers over which the line 

 was run. These latter are as follows: 



Little Suamioo

No indications of the existence of workable beds or veins of iron 

 ore were observed upon this route; if any exist they are further to 

 the north and west. 



Mr. Edgerton reports as follows: "The geological formation of the 

 country traversed I found to be much the same as indicated on your 

 map, except that I did not succeed is discovering any evidence of the 

 belt marked thereon as the St. Peters sandstone. The first cropping
