V4 Report of the State Geologist. 



1. A railway cut of a few feet in depth traverses the ridge 

 at a low point. The narrow ridge rises rapidly to the south ; 

 barely wide enough for a wagon; gravelly. Eeaching the 

 height of 60 (?) feet it becomes very sinuous and humpy, with 

 steep sides ; wanders a short distance about on a table-like hill 

 (210-300 feet wide), and is lost. 



2. The table, some way southward, descends; continues as a 

 straight, well-rounded ridge 25 feet high, apparently composed 

 of till, S. 5° E. for a quarter of a mile ; then widens and becomes 

 knoUy for half a mile. 



3. A long, straight N-S valley splits the ridge in two. The 

 west branch becomes much higher and takes on the habit of a 

 till-ridge, descending when near the kame, arid marked on its 

 well-rounded top with a longitudinal groove 200 feet long. The 

 east branch diverges very slightly, remains low (30 feet ?), has a 

 sandy soil with a number of stones, and a rolling surface. 

 Finally it changes at once to a very narrow, tortuous ridge 

 of heavy gravel, which runs (with a short break in the swamp) 

 half a mile to the central parts of the kame. 



The gravel ridge begins exactly where the sand ridge ceases, 

 with a partial disconnection of continuity, and indications as if 

 the former emerged from the pond just at that point. 



Delta Terraces. 



The " points " at Sheldrake and Lodi afford excellent examples 

 of the formation of modern deltas. They correspond with two 

 of the largest local streams, and represent the drift and rock 

 brought down by the streams since the lake has stood at its 

 present level. Projecting a quarter of a mile into the respective 

 lakes, with a greater breadth, at points where the descent of the 

 bottom is steep, they indicate a very large amount of filling. 



Along the sides of these and most of the other streams we find 

 important accumulations of the same materials that compose the 

 modern deltas. In part, these masses form low walls or embank- 

 ments running continuously for long distances on both sides of 

 the gullies. This may be seen in the region of steep slopes south 

 of Kidder's ferry. The streams here run parallel and very near 

 each other, so that there is but a moderate space between two
