  Jim & I started off in the hunting boat at 8 a.m. crossing                                        
the lake to Richardson's Carry, which we reached just as the fog
began breaking up. About midway of the passage in came upon
a White-throated Sparrow floating dead on the calm water. It                                                 
occurred to me that these birds which we find drowned in this                                          
lake after foggy nights may meet this fate by descending through                           
the fog at daybreak & striking the water before they make out what                         
it is rather than by wandering about in circles until they become                                
exhausted. This idea was suggested to me by the reflection that                          
the color of the water when it is calm & enshrouded in fog is                                 
precisely like that of the fog itself. Looking down at the Lake                                  
from a slight elevation I find that I cannot make out the                                       
water at all through this fog unless it is agitated by the swirl
of a fish or by a breath of air.

  As we neared the entrance to Leonard's Pond a Pigeon Hawk                            
alighted on a stub which stood on the river bank. We                                         
approached to within easy range when I saw that the
bird was a fine adult male but before I could raise the 
gun it flew and I missed it as it was making off.

  Less than one hundred yards further on I was surprised
to see at least a dozen Yellow-rumped Warblers in
a dying & nearly leafless maple which overhung the water.
They were hopping & flitting about but did not appear to 
be especially active or excited and were making no noise.
  While I was looking at them my eye was attracted to 
an upright, motionless form in the centre of the tree & 
this I made out through my glass to be another Pigeon
Hawk, a young bird, apparently a male. It was evidently
the object which had excited the interest of the Warblers
