tail wide and slightly parting the tip & terminal third of 
the wing from the side of the body just as she
disappeared. As the water was very shallow (about 3 ft.)
she had not far to go and she rarely remained under
more than 8 or 10 seconds and often not over 5.
(The young kept under fully as long). Thrice I saw her
bring up something of a vegetable character that looked
like a strand of eel grass. This she shook about
violently in her bill & finally swallowed without
offering it to the young several of which came close
about her. Nor did they show any interest in her
success. The brood swam out through the open
channel at the west of the island and were lost
to our view, shortly before noon.
