which immediately preceded and followed it. It probably could not 
be heard at anything like the distances to which the hooting of 
the Barred and Horned Owls carries under favorable conditions. 
The whistle is the same as that which we heard near this 
camp on the evenings of Sept.26 and Oct.5 and which we have hither¬ 
to attributed to a Saw-whet. It is possible of course that the 
whistle was made to-night by another bird but if so he and the 
hooter must have kept close company, for when the latter was behind 
the tent I heard both sounds in quick succession from apparently 
the same spot and later when the hooter had moved to the pines on 
the point near the landing, the whistle came again thrice from that 
direction and on each occasion the yells ceased while the whistle 
was being given . 
If I am not mistaken - and my men have the same impres¬ 
sion - this whistle was heard by us several evenings in 1889 and 
1890, when we were in camp near Moll's Hock, but the other cries, 
as I have already said, are positively new to us all.
