No. 1 (Figs. 1, 2.) This may branch from No. 2. As an 

 independent ridge it proceeds from its head (about a quarter of 

 a mile below Calvary Cemetery) southward and almost parallel 

 with the Cincinnati Pike to a point almost opposite Dorothy 

 Lane (Fig. 1 ) where it ends in a cut. The upper end of this esker 

 though distinctly ridged is not as typically esker-like as the lower 

 end. Intersections between No. 1 and No. 2 occur near their 

 southern terminals. These intersections at one point form a 

 " Y", the base of which starts from No. 1, the branches leading 

 to No. 2. At all the intersections, four in number, the ridges

rise, forming knoll-like prominences. Small boulders about the 

 size of cobbles are abundant on the surface. These are large h' 

 of local limestone of the same formation (Cincinnati) as that seen 

 in the rock spur before mentioned. The exposed cut at the road 

 shows principally coarse gravel mingled with sand. Some of this 

 gravel has been cemented together into a form of conglomerate 

 by the action of carbonated water. ^^ Several feet of till contain- 

 ing a large percentage of small boulders overlies the gravel at 

 this point. This exposed section at the time of the writer's 

 first visit revealed the anticlinal stratification frequently men- 

 tioned in offering sub-glacial theories of origin. This may pos- 

 sibly be explained, however, by slumping of the material after
