same course around the shore which they had
taken in the forenoon, diving incessantly, and again entered

the day. This note was repeated scores of times with
ever increasing shrillness until it became almost a shriek 
somewhat husky and cracked in tone. Feeling sure that
something must be wrong I watched intently but for a 
time could see nothing. Finally the mother crossed a space
of open water unattended by any of her young. A moment
later a large brown bird, evidently a Hawk of some kind,
swept down on set wings and as it reached about the
level of the water disappeared behind the trunk of a large tree.
