FIG. i. A view looking lengthwise E. & W. of the "embayment" 

 discussed in the text. In the extreme right winds the main branch of 

 Cherry Creek while on the left may be seen the higher points of the la- 

 custrine beach. The vegetation, both of the trees and the undergrowth, is 

 very characteristic of such a slope. The trees vary from the black and 

 white oaks on the left to poplars, sycamores, and elms in the centre and 

 the black willow (salix nigra) on the right. In the left foreground are the 

 bogs mentioned, in which the biological remains are so well preserved. 



FIG. 4. View at the point of greatest gradient and erosion in the 

 head waters of the Tippecanoe where the stream has all but succeeded in 

 tapping Eagle Lake. The lake is less than a half mile distant. The view 

 also looks diagonally across the site of the greater dam to the southern 

 abutment. This is 22 feet high, at the base of the large white oak in the 

 back. The stones in tha foreground are nos'.ly limestones of the till.
