INTRODUCTION. 



Boundary Lines. 



The boundary-line of Hinghain, commencing on the water- 

 front at Cohasset, near the head of Nantasket Beach, runs west 

 through an elongated inlet of the sea or bay which lies east of 

 the lower waters of Weir River, and from thence follows along 

 this river, and subsequently skirts the coast at the base of the 

 hills known as Planters' and World's End, in a northwesterly 

 direction until it passes the latter, when it turns westerly and 

 crosses outside the harbor of the town and the shores north to 

 the mouth of Weymouth Back River. From there this river 

 forms the boundary between the town and a part of Weymouth 

 to the head of navigation, about three and a half miles. The other 

 boundary-lines are artificial, dividing the town on the west from 

 a part of Weymouth not separated by the river, on the south and 

 southeast from Rockland and Norvvell, and on the east from Cohas- 

 set. The boundary-line of the harbor leaves exterior to it Bunkin 

 Island, which belongs to Hull, and that of the southern boundary 

 crosses Accord Pond, the beautiful sheet of water from which 

 Hingham draws its abundant supply. 



The shore-line of the water-front of the town, as distinct from 

 that of the boundary, is much more extensive, following as it does 

 the numerous indentures of the coast, and embracing the circum- 

 ference of the islands. Notice should be taken of the distinction 

 between the boundary and shore lines, as they comprise the limits 

 between which the marine forms of life appear that may be here- 

 after mentioned. 



The coast bordering upon the Weir River and Bay is of varied 

 and picturesque character, with its alternating rocky projections 

 and swampy plains. The shore-line, too, from Crow Point west
