noe, White, eastern Benton, southern Newton, and southern Jasper counties, and 

 receded eastward from these counties. The author maintains instead that the ice 

 from the Lake Michigan basin overspread nearly the whole area of these counties, 

 and that its recession was northwestward. The sketch maps which accompany the 

 paper represent several supposed outlines of the ice margin in the course of its retreat. 

 The author's interpretation and mapping are not supported, however; by the distribu- 

 tion of moraines, border drainage channels, and other features which are commonly 

 used by glacialists in determining the outline which an ice-sheet presented at a given 

 time. Instead other features are taken to indicate the position of the ice margin. In 

 one case a change from a level to an inclined plain, in another the irregularities of 

 the Wabash bluff produced by postglacial drainage, appear to have been interpreted 

 as marginal features.

The bowlder belts are interpreted to be a sort of beach formation, produced by the 

 stranding of icebergs and floe ice in shallow lakes.

The terraces are classified as high and low, the former being 80 to 130 feet 

 above the river, and the latter but little above the modern flood plain. Reference is 

 made to the occupancy of a preglacial valley by the Wabash throughout much of its 

 course in Tippecanoe county, whose rock floor is about 150 feet below the present 

 stream. A map repeats the views of earlier papers (reviewed above) as to moraines 

 and lake beds.

 Proc. Indiana Acad. Sci. for igoi.pp. 244-47, 1902. 



The creek is found to have its course governed by the slopes of the region, but 

 the author thinks that its drainage basin was submerged for a time after the ice had 

 disappeared, and it was not until the supposed lake had drained away that the creek 

 began to open a course in conformity to the slopes.

 Monroe County, Indiana. Proc. Indiana Acad. Sci. for igoi, pp. 222- 

 37. 1902. 



The valley of this creek is found to have been formed by a meandering pre- 

 glacial stream. There has been a large amount of filling vpith earthy material, 

 which also is found to antedate the deposition of the glacial material. The ice-sheet 

 covered the head waters and also the lower end of the valley, but the middle portion 

 is unglaciated. An arrest of drainage which resulted from this ice invasion is shown 

 by the presence of benches along the valley borders where material was brought into 

 the flooded valley by tributaries at levels considerably above the valley bottoms. 

 These benches stand about 70 feet above the bottoms in northeastern Monroe county, 

 but are only 25 to 30 feet above them in the northwestern part of the county. The 

 difference is interpreted to be due to a greater accession of material in the higher 

 benches than was received in the lower, rather than to different lake levels.
