1899. Along the river on my way down, I saw an Osprey. 
April 11. The Osprey was perched on a stake eating a large fish. Sever- 
al Crows were mobbing him viciously. Gilbert tells me that 
he saw the. same thing happen near the cabin this morning and 
that the Osprey (who was flying) was so hard pressed that he 
finally dropped his fish. It fell into the water among some 
bushes directly in front of the cabin. The Crows did not 
attempt to take it. I doubt if they were after the fish in 
either case. Just as I was finishing the proceeding sentence 
I heard an Osprey whistling and stepping out discovered him 
perched on the top of a white pine on the crest of Ball's 
Hill .
