FORM OF NANTASKET BEACH 175 



Hill (H) without danger of appreciable error. This has been done 

 in Fig, 4, the restored portions being indicated by broken lines. 

 Where more than half of a drumlin has been destroyed, the restoration 

 cannot be made with the same degree of certainty, and we recognize 

 that the location and size of such drumlins cannot be determined with 

 absolute precision. The margin of error is not so large as materially to 

 affect our problem, and the restorations of Quarter Ledge drumlin (Q) 

 and Allerton Little Hill (L) in Fig. 4 (restored portions in broken 

 lines) are believed to be essentially correct. The position of Little 

 Hill will account for the peculiar protuberance of beach material 

 northwest of Great Hill, if we agree that a spit trailing back from 

 Little Hill by the action of waves and currents through Nantasket 

 Roads would have a form somewhat similar to that of Windmill Point 

 (WP) in Fig. 8. The restoration of the drumlins which are wholly 

 destroyed involves a larger chance of error, and each individual 

 restoration of this kind must be carefully considered. 



The first restoration of a drumlin now completely destroyed 

 (complete restorations shown by dotted lines) is that of Allerton Lost 

 Drumlin (AL). That this drumlin formerly existed is shown by the 

 relations of West Beach. The beach does not connect with Great 

 Hill at the present time, but is abruptly cut off by the present shoreline 

 a short distance south of Great Hill. That this beach formerly 

 continued toward the east seems clear. It is equally clear that the 

 seaward continuation of the beach would not connect with the seaward 

 continuation of Great Hill, unless we imagine the beach to have been 

 bent sharply northward. This last assumption is contrary to what 

 we should expect in a beach as well developed as West Beach, has no 

 evidence to support it, and is one which we are not permitted to make 

 arbitrarily. . The precise location of the drumlin with which West 

 Beach must have connected cannot be determined with certainty, 

 nor can its size be inferred; but that it occupied some such position 

 as is indicated in Fig. 4 there would seem to be little doubt. It is 

 not permissible to consider West Beach connected with the eastward 

 extension of Little Hill, for this would require a marked northward 

 bend in the beach, or the reconstruction of Little Hill on too large a 

 scale. 



It will be convenient to consider the restoration of Skull Head
