Patrick or 77G feet at New Kicbuioud. The recession of the ice from 

 the present line of the Wabash removed the back wall from this arrange- 

 ment of features and the gradual cutting down of the valley of the 

 Wabash eventually drained the larger and sevei-al succeeding smaller 

 lakes and permitted the establishment of the present drainage of south- 

 eastern Tippecanoe County. 



It may now be said that an extension of the same process further 

 north and the disappearance of the Ice along the line of the Tippecanoe 

 to its great bend, and along the upper Kankakee, while the ice still occu- 

 pied the country to the west, would make quite simple the problem of 

 Lake Kankakee and other temporary glacial lakes. 



The arrangement of moraines along the north bank of the three forks 

 of Wild Cat Creek together with the pirating of the heads of several 

 southern tributaries of the Wabash indicates a comparatively rapid 

 northward recession of the southern edge of the Erie lobe. 



The region embraced in the Wabash basin still doubtless presents in 

 almost everj^ county interesting problems for the intelligent investigator 

 who may care to look for them, and the facts and opinions here set forth 

 are intended as suggestions to be verified or rejected by others or myself, 

 after further investigation. 



Note: In No. 3 and No. 4 of maps illustrating the development of the 

 Wabash drainage system I have indicated the probable line of interlobate 

 melting. I have suggested the name^ Tippecanoe Gulf for this reentrant 

 area. 



A Theory to Explain the Western Indiana Bowlder Belts. 



By W. a. McBeth. 



The proximity of the bowlder belt southeast of Independence, Warren 

 County, to the moraine which parallels It a little distance to the west, 

 is a marked relationship. The bowlders lie on and along the foot of the 

 eastward slope of the moraine. Where the slopes are gentle the belt 

 widens out, and on the abrupt slopes the width decreases and the bowlders 

 are more numerous. There are also patches of them on the ridges and 

 knolls that lie to the east at levels lower than the main divide. Bowlders 

 are not infrequent anywhere in the whole of western Indiana, but are
