crossing this, and taking a southeast course toward Crown street, 

 and then diagonally southeast to Macmillan. Along Macmillan to 

 Gilbert Avenue seems next its course, and then from the junction 

 of these two streets it goes diagonally to the bluff, south of Mac- 

 millan street, and immediately over-hanging the river. Here it 

 ends abruptly, and all the drainage of East Walnut Hills is carried 

 east and north into ravines running into Crawfish and Duck 

 Creeks, and far north into Mill Creek. 



l"he peculiar features of ravines, heading up on both the south 

 and the north sides of the divide, reminds one of the remarks of 

 Capt. Button, quoted in part one of this paper, that in mountainous 

 countries the ravines form a series of amphitheatres close to a nar- 

 row divide which remains sharp in all stages of erosion. We find 

 this to be exactly the state of affairs on Calhoun and Auburn 

 streets, for there, on both north and south sides, the heads of ravines 

 come up close to the narrow knife-like water shed. 



While the Mt. Auburn and Ohio Avenue ridges project to the 

 southward of the divide, there are others of a similar character on 

 the north. One of these runs in a long, beautifully gentle slope 

 through the western side of Burnet Woods Park, and the other is 

 utilized by upper Vine street and Ludlow Avenue. The two latter 

 form the main streets of Corryville, and if the former ridge were 

 not a portion of Burnet Woods, there is no reason why it should 

 not have Iniilt upon it a new suburb equal, if not superior, in 

 beauty, to Clifton Heights and Mt. Auburn. 



Walnut Hills, on the contrary, occupies no such pronounced 

 tongue of land, but covers, with its fine residences, a vast undula- 

 ting tract, the most level of all that remains of the plateau which 

 once existed. Avondale, too, occupies a similar rolling tract 

 of country, and is also situated on the northern slojje of the 

 divide, so that all its drainage flows into Mill Creek to the north- 

 ward, though eventually into the Ohio. 



On the east side of Avondale, beginning about half a mile from 

 Macneale Avenue, is one of the most beautiful valleys in the 

 neighborhood of the city. At its upper or southern end it is rather 

 narrow, and through its centre wanders a small brook. As we go 

 down the valley widens and deepens. The little brook becomes 

 larger and cuts deep into the rich soil, and the green hill-sides rise 

 on either hand with few or no trees. Toward the lower end trees 

 become more abundant, but in no case do they form a thick
