and probably connects with a very well-marked belt lying near 

 the south line of the southeast quarter of Marion county and in 

 the northeastern part of Johnson county. There is also a well- 

 defined tract in southeastern Hendricks county, running east and 

 west, without evident connection with the foregoing tracts, 

 though it may be the equivalent of the Darlington belt. There 

 is also a somewhat unusual aggregation in the form of irregular 

 belts in southeastern Johnson county, in the vicinity of Nineveh, 

 and in southern Shelby county. The belt south of Indianapolis 

 is probably to be correlated by scattered boulders only slightly 

 more abundant than those of the adjacent region, but of the 

 surface type, stretching northeasterly to near the center of the 

 west half of Henry county, where a well-marked belt again sets 

 in. From this point the tract runs northeasterly nearly to the 

 north limit of the county, where it turns easterly and runs in the 

 vicinity of the line between Randolph and Wayne counties to 

 near the Ohio line, where it curves to the southeast entering 

 Ohio near the northwest corner of Preble count3^ In its south- 

 easterly course across that county it is phenomenally developed 

 as has been well shown b}^ the descriptions of Professor Orton. 

 Soon after entering Montgomery county it curves about to a 

 northeasterly course, and crossing the great Miami river, a few 

 miles above Dayton, holds its northeast course across the south- 

 eastern part of Miami county, the northwestern part of Cham- 

 paign county, and thence on to about the center of Logan 

 county, where it curves about and runs in a direction a little east 

 of south to near the southeast corner of Champaign county, 

 beyond which it ceases to be a specially notable phenomenon. 



In the region between the Wabash and Kankakee rivers, in 

 northern Indiana, there are numerous tracts of irregular form 

 over which surface boulders in phenomenal abundance are 

 scattered. These are particularly noticeable in southern Jasper 

 county ; in the vicinity of Wolcott, Monon and Chalmers in 

 White county ; near Star City in Pulaski county ; in the south- 

 eastern corner of Stark county, and very generally along the 

 great interlobate moraines, lying parallel with the Eel river,
