beach, but are strongly curved, concave toward the east. At the 

 extreme west, however, these curved beaches become prominent 

 features once more and are as high in places as the modern beach. 



If we examine the older beaches more carefully, we note several 

 significant points. Just south of Allerton Great Hill the high and 

 prominent westernmost beach, Avhich we may call West Beach, is 

 intersected by the modern beach. West Beach does not touch Great 

 Hill and from the curvature of the beach it seems hardly probable 

 that it connected with the former seaward extension of Great Hill. 

 At its southern end West Beach ties to the northwest side of Straw- 

 berry Hill, just in front of the only part of the hill which has no 

 bordering marine cliff. From the western side of the beach projects 

 the protuberance of the Skull Head area, which destroys the otherwise 

 symmetrical curve given to this portion of the harbor shoreline. Of 

 the beaches which intervene between West Beach and the modern 

 beach, a few connect with Strawberry Hill, others curve eastward as 

 if to connect with something formerly situated in front of Strawberry 

 Hill, and still others pass in front of the hill to connect with White 

 Head or Sagamore Head farther south; while at the north all converge 

 toward the intersection of West Beach with the modern beach, merging 

 with the former or being cut off by the latter. The waves from the 

 harbor are now attacking West Beach north of Skull Head, giving it 

 a steeper western face, cutting off part of the western convexity, and 

 building a small subsidiary beach toward the north. This attack 

 of the harbor waves upon a beach formerly constructed by the power- 

 ful Atlantic waves has become so effective that sea-walls have been 

 built in places to prevent further destruction of the old beach. 



South of Strawberry Hill the relations are much the same, except 

 that the beaches are less distinct and less regular in outline. The 

 equivalent of West Beach does not connect directly with Strawberry 

 Hill, but is truncated by a more recent beach or spit which extends 

 southward from the southwest end of the great cliff on Strawberry 

 Hill. The older main beach curves rather strongly southwest, con- 

 tinues south and southeast in much broken and complicated ridges, 

 and finally spreads out in a broad, indefinite plain of beach material 

 near the western end of White Head. The most prominent beach 

 in this vicinity is one which extends from the eastern point of Straw-
