CONCORD.

June 16 
At 9 A. M. started down river in the open canoe. 
Landed at Birch Island and walked to the Farm. To my great 
surprise, a Solitary Vireo was singing in the woods directly 
behind the barn. \Vhere can he have come from at this late 
season? He sang steadily during the hour or more that I 
was within hearing and acted as if he were quite settled- in 
this little isolated grove. Indeed when I entered it to 
look for him he came directly to me, hopping about in an 
oak within a few yards of me, scolding me v/ith the chattering 
cry which is com.non to both solitarius and flavifrons , and 
uttering also some low, exquisitely liquid notes. Presently 
he resumed singing again. He was a fine old bird with 
deep bluish head. 
The female Hummer was sitting quietly on her nest 
when I passed under it at 10 A. M. 
The Bats are roosting in the shed again, I found 
a bunch of seven in the inner chamber and another of six 
in the outer one at the head of the stairs. They hang so 
closely clustered together that it is difficult to count 
them. They took absolutely no notice of me when I 
approached so near that my face was literally within six 
inches of them. Nor was there the slightest movement among 
them save that of the pulsations caused by their breathing. 
The bunch of seven seemed to be made up of tvro old ones 
and five young; at least, two were fully twice as large 
as the other five. The floor beneath them was covered 
with their dung which resembled that of rats.
