directly under her without attempting to fly.^ 
At 2.15 P. M. I heard a Sreat Horned Owl hoot over in 
the dense pines on the Prescott Hill. The sun was shining 
brightly at the time and there was almost no wind stirring. 
About two hours later (4,20 P. M.) a pair of these Owls 
began a wonderful serenade to v/hich I listened attentively 
and ViTith the keenest enjoyment for upwards of half-an-hour, 
when both became silent. 
One of them within fifty yards of me in the large 
dense pines on the ridge above the G-lacial Hollow invariably 
uttered five notest hop . hoo-hoo ; hop ; hoo . There was 
regularly a short but well-marked pause after the first note, 
the second and third notes v/ere given in. rapid succession, 
a carefully—measured and impressively long interval followed 
the third note while the interval between the fourth and 
fifth notes was about half as long as that between the first 
and second notes and that sepasatine: the third and fourth. 
The bird’s voice was, I think, the deepest and most 
sonorous that I have ever listened to from any , while 
the carefully measured intervals made it tremendously impres¬ 
sive. 
The other bird v;as apparently about two hundred yards 
distant and somewhere on Davis’s Hill. Its hooting was 
radically different. Usually it uttered eight notes ( hop , 
hoo-hoo- hoo , hoo- hoo- hoo , hoo ) but occasionally there were 
nine ( hoo-hoo , hoo-hoo-hpo , hoo-hoo-hoo . hoo ).It s voice 
was lighter and more woodeny than that of the first bird
