In the absence of figures of actual surveys the impression is that the 

 floor of the Furnessville Blowout is probably lower than the floors of 

 other blowouts in the region and also that it is approximately the same 

 height as the low ground between the dunes and the tracks of the Chi- 

 cago, Lake Shore and South Bend Railway. Although I have been in 

 many of the blowouts in this region, between Michigan City and Oak 

 Hill, the one designated as Furnessville is the only one in which I have 

 found these shells. 



No opinion is ventured as to the significance of these shells at the 

 place indicated.
