54 THE ISLAND OF NANTUCKET. 



the body of the island? It is to be remembered that 

 the course of the waters from the melting southern 

 rim of the glacier that lay where Sancoty, Saul's, 

 Popsquatchet, and Trot's Hills stand, was southerly. 

 Those waters would wash away the lighter part of the 

 "till," or materials of which the top and southern 

 sides of the moraine consisted, and convey those 

 materials down in a southerly direction. Thus prob- 

 ably were formed, by deposition of gravel, sand, occa- 

 sional small bowlders, and clay, the plain or slightly 

 rolling expanse between Saul's, Shawkemo, Pop- 

 squatchet, and Trot's Hills at the north, and the South 

 Shore line at the south, — the expanse, namely, now 

 known as the Southeast Quarter, South Pasture, 

 Smooth Hummocks, the Plains, and Great Keck; leav- 

 ing the larger rocks or bowlders, such as Altar Rock, 

 Table Rock, Split Rock, and the rock to be seen at the 

 north from the 'Sconset road, unmoved, projecting 

 above the surface of the hills, and bare, and giving at 

 the same time the rounded and dome-like character to 

 Saul's, Trot's, and the other hills. This theory, too, 

 would account for the fact that the hilly part of the 

 island lies along the entire north side of its main body, 

 while the lower and more level part lies at the south. 



Furthermore, there is a slightly rolling and uneven 

 character in this comparatively level or southern part. 

 It is cut by parallel valleys or depressions, lying in a 

 general north-south direction ; e. #., Coffin's, Star- 

 buck's, Madequecham, and the Weweeder, Macomet, 

 Hummock, and Long Pond depressions. 



It is probable that at times, especially in times of 

 warm rain, the melting waters flowing from the lower
