Maumee river. This is the major stream of many smaller rivers 

 that belong to the northwestern part of Ohio. The Maumee 

 itself rises in Indiana. Of its Ohio tributaries the principal 

 are: on the north, the Tiffin river, which flows southward from 

 Michigan, joining the Maumee at Defiance; on the south, the 

 major tributary is the Auglaize, which rises in an extensive 

 swamp section northwest of Kenton in Hardin county. One of 

 the more significant tributaries of the Auglaize is Ottawa creek 

 which rises near Ada, also in the swamp district. The Blan- 

 chard river, another branch of the Auglaize, flows from the 

 same marsh area in Hardin county ; for about twenty miles, its 

 course is directly north; reaching the meridian of Findlay, it 

 turns westward through Ottowa, and joins the Auglaize near 

 Dupont. Many other smaller tributaries, on account of the direc- 

 tion of the moraines, also have a general westerly course. On its 

 western side, the Auglaize has numerous small branches draining 

 Paulding and Van Wert counties. The river takes its name from 

 the fact that several of its headwater streams rise in Auglaize 

 county. 



From Defiance to Toledo, the Maumee is a very sluggish stream. 

 It has not been of much use in navigation, as appears from the 

 fact that a canal had to be built along its channel. Wood, Henry 

 and Fulton counties give rise to several minor tributaries of the 

 Maumee. 



Ohio River Drainage 



The longest rivers of the state are tributary to the Ohio. 

 Many of these, when studied closely, show puzzling relation- 

 ships. The Ohio itself has had an intricate history; some of its 

 tributaries embody even greater complexities of origin, as already 

 described. 



Great Miami. The general course of this stream, w^hose basin 

 involves about 4000 square miles, coincides with the axis of the 

 Cincinnati arch. At first thought it may appear as an anomalous 

 condition for a river to flow along the axis of an anticline. When 

 such an anticline involves limestone formations, ultimately 

 the drainage takes just such a course. The principles involved 

 in the development of such a course have been fully discussed and
