as wide as that occupied by the river above tliis point. From Hnntiiigton 

 it flows in a westward course and has opened up a post glacial line as 

 far as Lafayette, where it joins a preglacial channel as mentioned above. 



Big Raccoon Creek and its main tributary Little Raccoon Creek drain 

 an area of about 50O square miles. At the southern edge of Parke County 

 the stream enters an old channel of the Wabash and follows this chan- 

 nel for about fifteen miles northward before entering the Wabash. 



Busseron Creek, a tributary of the Wabash, has its source near the 

 Clay and Vigo line. The general direction of the stream is southwest 

 across Sullivan County into the Wabash. For a few miles near the mouth 

 the stream probably occupies a i)reglacial channel, otherwise it is not in- 

 fluenced by preglacial drainage. 



There are two Eel rivers within the State. One a tributary of the 

 Wabash entering at Logansport and the other a tributary of White River 

 entering just aI)ove Worthington. 



Along the latter and its tributaries are some of the best rock ex- 

 posures in southern Indiana. These exposures are chiefly in the Mans- 

 field sandstone. It is a very meandering stream and at present the ques- 

 tion of the drainage of some of the bottom lands which are subject to 

 overflow is i-eceiving serious consideration in Clay, Vigo and Greene 

 counties. From the great bend westward to the Wabash there is a con- 

 tinuous strip of almost level country. 



The Salamonic River enters the Wabash from the southeast near the 

 city of Wabash. The river is about seventy-flve miles in length and 

 flows alojig a plain along the south side of a moraine. The Mississinewa 

 enters near Peru. It has a length of about 100 miles and its channel is 

 cut mainly in drift, but in a few places down to solid rock. The Tippe- 

 canoe River is the main tributary from the northwest. Its source is 

 in the moraines in the northeast part of the State. Its course is con- 

 trolled by the moraines. From the moraines it passes through a sand 

 plain of "Old Lake Kankakee" then again follows the course of a moraine 

 along the northwest side of the Wabash, and enters it a few miles below 

 Delphi. 



The Kankakee River Is a very sluggish stream, flowing a distance of 

 about seventy-five miles in Indiana by a very meandering course in whicli 

 the river is said to make 2,000 bends
