on tlie map — Lower Plain, Glad Tidings Plain, and Liberty 

 Plain. 



Lower Plain, with a normal height of from 50 to 55 feet, has its 

 best development between High Street and the railroad, west of 

 Weir River, including Hingham Centre and the district about 

 Great Hill. Toward the west and northwest especially, it loses, 

 very largely, the character of a [)lain, dividing into irregular 

 rounded hummocks and windinfr ridij^es or cskers euclosino; 

 numerous kettle-holes and small jjonds and bogs. In this 

 fragmentary form, only rarely attaining its maximum height, 

 this plain has a particularly interesting development in the 

 Hockley district between West Hingham and Weymouth Back 

 River. The fine series of cskers between Ideal's Cove and 

 Stoddard's Neck should be referred to this plain, and also the 

 plain (40—50 feet) so well develo[)ed around the southern 

 end of the harbor. Eastward, along the line of the railroad 

 and East Street, it can be traced into Cohasset, where we have 

 already recognized it as the principal plain of that town. There 

 is, however, in the vicinity of the coast, a distinctly lower 

 plain, with a normal height of from 20 to 30 feet. This is very 

 perfectly devcloj)ed between Beal Street and Iluit's Cove and 

 may be traced at intervals througii the northwest part of the 

 town. Glad Tidings Plain extends from the vicinity of High 

 and Free Streets south to the northern margin of Liberty 

 Plain, embracinp- Cushinc: and Fullinjji' jNIill Ponds and havinir 

 a normal height of from (35 to 70 feet. Liberty Plain lies almost 

 wholly south of the southern boundary of the nnip, embracing 

 Accord Pond and extending into the adjoining towns. It rises 

 very abruptly from Glad Tidings Plain to its normal height of 

 130 or 135 feet. 



Each plain is developed to some extent in the form of out- 

 liers or islands on the next lower one, and, conversely, kames, 

 eskers, or limited plateaus rising from the surface of either 

 plain may be n^garded as representing in height and age the 

 next higher plain. The eskers known as Break-neck Hills,
