short distances, but at last the line changes from hillocks to a 

 straight single ridge, which becomes more abundant in stones, 

 and after crossing the State Road presents a top soil well 

 filled with typical drumlin material. Smaller sand trains lie 

 parallel to this, east and west. A mile to the eastward lies a 

 large ridge of similar material and extent (see G-ibson's map), which 

 near its southern end develops into a veritable little kame-group of 

 sand hills, covered in parts with several feet of gravel dipping at a 

 high angle from the center. Here is another " sand quarry ", 

 used for many years to supply building material for the neigh- 

 boring country. Farther to the east there are undulations for 

 a mile or two, of the same character. Westward, the plain 

 toward Waterloo looks unbroken, but other exposures of sand 

 (probably similar) exist on the westward line north of that 

 village. 



Kame District. 



The above series of ridges of modified drift, forming a fringe 

 to the drumlin district, must probably be connected with that 

 much larger group of kame hills which lies at the western bound- 

 ary of Junius, opposite Mitchell's station on the Geneva and 

 Lyons railroad. 



This latter group is about two miles in diameter in either 

 direction, consisting of gravel and sand hills, to 50 feet 

 high, embracing deep basins which contain several lakelets. 

 The topography is very irregular and is well sho wn in the view, 

 Figure 13, which gives only one of the ponds. Around the region 

 of hills lies a belt of sand on the east, south and west, which 

 evidently belong to it. In many places the sand is gullied very 

 deeply, especially on the steep slope westward to the outlet of 

 Canandaigua lake, which runs in a rather deep valley for these 

 parts. The rise from the surface of the stream to the high 

 gravel hill at the north face of the kame is, by hand-lev«l, 160 

 feet. Several other high points are of nearly equal elevation. 

 Figure 14 shows a part of the sand-slope toward the outlet. 

 To the east the descent is much less, and the swales are of lesser 

 size. Southward, the sand runs about six miles, stopping a 

 couple of miles before reaching Seneca lake ; it is continuous
