At the southern end of the main island stand two partially isolated 
“ Nubbles,” obviously once a part of the main island, consisting of 
masses of sand and clay, heavily wooded with small trees, resting upon 
granitic rocks. The larger is now cut off from the main island at 
every high tide, but the smaller is still attached to it by a low ridge 
of sand, never, or extremely rarely, crossed by the tide. Around the

islands are many ledges, shown on the maps (Figs. 3, 4), connected 
with one another by sand, gravel and boulders, extending on the 
eastward into a remarkable, long, sandy point. Beyond the low-tide 
limits of these ledges, as a rule, the shores slope down rather abruptly 
to the greater depths of the river; so that the ledges as a whole repre- 
sent a rather distinct and marked elevation above the general bed of 
the river. 
The only buildings upon the island are those of the United 
States Light Station, comprising a house with the lantern, carrying 
a revolving flash light, upon its roof, and various lesser buildings 
connected with the station, together with a small shed used by the 
weir fishermen (Fig. 14). The only residents are the keeper of the 
light and his family.
