The ebb of a spring tide always draws the water off a

broad strip of this mud, and then flocks of gulls appear

from all over the Upper Bay and light on it and thrash

around and scratch for clams. They fly up with clams in

their beaks and drop them on the concrete walk that runs

along the top of the island’s sea wall, and then they swoop

down and pluck the meats out of the broken shells.
