On Little neck, the hills on the west side are low, and are skirted mostly by salt marsh, 
with a beach next the shore. White clay was found by Mr. Briggs on the north or northwest 
side, similar to that of East neck. The clay has been dug for use, but the bed was nearly 
concealed by the superincumbent sands having crumbled and slidden down. Various kinds 
of clay were stated to exist on Capt. Sill’s farm, adapted to the manufacture of pottery, 
stone-ware, bricks and fire-bricks; but the pits were filled with sand and water when Mr. 
Briggs visited the locality. Capt. Sill mentioned to Mr. Briggs a remarkable locality on one 
of the hills of Little neck, on which he stated that he had never known snow or ice, although 
it was on sandy ground, and on a space several yards square.* 
Sandy clay was seen near Northport, in several places. It is like that observed on the 
east side of Little neck. 
From North point to Eaton’s neck beach, the cliffs are from ten to ninety feet high, but the 
geological structure was concealed by the sand having slidden down to the beach. 
Eaton’s neck was formerly a cluster of four islands, now connected by beaches and salt 
marshes. The principal of these islands, and the only part of the neck that is cultivated, is 
about two and a half miles long, and one and a half miles wide, and is composed of the ter¬ 
tiary strata, covered in some places by the drift and quaternary deposits. The strata of this 
island are similar to those of Lloyd’s neck. The following is the order of superposition as 
nearly as could be ascertained, the sand-banks having crumbled and slidden down in many 
places, so as to conceal partially, or entirely, the fresh sections that had recently been ex¬ 
posed along the shores. 
* This, if so, and not covered, is a remarkable fact; but it looks so improbable, that I am inclined to mistrust it as a quiz, I 
have, however, heard of a similar spot in Guilford (Conn.), on one of the trappean hills, as it is said to be, where snow always 
melts as fast as it falls ; but there, pyrites are said to abound in the rock, and to decompose, and the heat and the excess of sul¬ 
phuric acid are a plausible and sufficient explanation.
