nels, thus forming partly enclosed harbors, lagoons, sounds, or bays, 
as they are variously called. Every stage in this process can be 
seen in progress. There is a little landlocked cove on Coney Island, 
with a shell-sand beach, but connected with the open water only by 
a narrow channel, between limestone ledges, barely wide enough for 
a row-boat to pass through (fig. 30). A similar miniature harbor 
may be seen near the roadside between Bailey Bay and Shelly Bay. 
It is said to have become connected with the sea, in quite recent 
times. Peniston’s Pond is a larger body of water, separated from 
the sea only by a low bar, over which the waves pour a large amount 
of water in storms.

ledges. 
It is evident that the sea will soon cut a channel through the bar 
and convert it into a small bay or harbor. This has already hap- 
pened at Hungry Bay, farther west, which was evidently shut off 
from the sea formerly by a similar bar, which has been breached by 
erosion. The tide now flows in and out, through a narrow channel, 
in a rapid current. This bay is shallow and the inner end terminates 
in a dense mangrove swamp of considerable extent. 
Elies’ Harbor and the “Scaur” are other good examples of the 
same action. 
It is easy to see that this same process, when it opens up larger 
valleys, or sinks, will give rise to larger lagoons and sounds.
